If you’re a health-conscious consumer or culinary enthusiast who shops at Costco, you’ve probably asked yourself: Does Costco carry plain yogurt? The answer is a resounding yes — and not just any plain yogurt, but a wide variety of high-quality, nutritious, and budget-friendly options that can suit nearly every palate and dietary need. Whether you’re using it for breakfast, smoothies, cooking, or as a base for homemade dips, Costco’s yogurt selection offers excellent value for bulk shoppers.
In this comprehensive guide, we’ll explore Costco’s extensive offerings of plain yogurt, diving into types, brands, health benefits, storage tips, and even creative ways to use plain yogurt in everyday life. By the end of this article, you’ll know exactly what to expect when you head to the dairy section — and how to make the smartest choice for your household.
Why Plain Yogurt Is a Staple in Health-Conscious Kitchens
Plain yogurt is more than a simple dairy product — it’s a nutritional powerhouse. Packed with protein, calcium, probiotics, and essential vitamins like B12 and riboflavin, it supports digestive health, boosts immunity, and contributes to strong bones and muscles. Unlike flavored yogurts, which often contain added sugars and artificial ingredients, plain yogurt is versatile and minimally processed, making it a favorite among nutritionists and foodies alike.
For families and meal preppers, buying in bulk from warehouse clubs like Costco helps maintain a consistent supply without constant trips to the grocery store. This is where Costco shines — providing large quantities of plain yogurt at cost-effective prices.
What Types of Plain Yogurt Does Costco Offer?
Costco’s yogurt aisle typically features multiple types of plain yogurt, catering to different dietary preferences and culinary uses. While availability may vary by location and season, the following categories are commonly found:
Whole Milk Plain Yogurt
This creamy, rich option is made from whole milk and contains a higher fat content compared to its low-fat and nonfat counterparts. Whole milk yogurt offers a luxurious texture and is ideal for cooking and baking, where fat contributes to a more satisfying mouthfeel.
Popular Brand Example: Kirkland Signature Whole Milk Plain Yogurt
Costco’s in-house brand, Kirkland Signature, offers a 5-pound tub of whole milk plain yogurt — frequently a standout in taste tests. Consuming this variety provides a balanced profile of nutrients and is especially popular with those following low-carb or ketogenic diets, where healthy fats are encouraged.
Low-Fat (2%) Plain Yogurt
For shoppers looking to reduce fat intake without sacrificing too much flavor, low-fat plain yogurt strikes a nice balance. With 2% milkfat, it’s less dense than whole milk yogurt but still retains a pleasantly smooth texture.
This type is ideal for those managing calorie intake while still wanting a satisfying dairy product for snacks or meals.
Nonfat (Fat-Free) Plain Yogurt
Nonfat plain yogurt is perfect for those focused on high-protein, low-fat diets. It’s commonly used in smoothies, dressings, and savory sauces where fat content needs to be kept minimal.
Despite the absence of fat, nonfat plain yogurt can still offer a tangy flavor and excellent probiotic content. The Kirkland Signature Nonfat Plain Yogurt — sold in 5-pound tubs — is a popular choice, praised for its thick consistency and clean ingredient list.
Greek-Style Plain Yogurt
Greek yogurt has skyrocketed in popularity due to its thicker texture and higher protein content. At Costco, Greek-style plain yogurt is strained to remove excess whey, resulting in a product with roughly double the protein of regular yogurt.
This variety is particularly favored for post-workout recovery, breakfast bowls, and as a healthier substitute for sour cream in recipes.
Top Pick: Kirkland Signature Greek Nonfat Plain Yogurt
This colossal 5-pound (or sometimes 6-pound) container is a fan favorite, offering a dense, creamy texture with around 23 grams of protein per cup. Many reviewers highlight that it rivals premium brands like Chobani or Fage in taste and consistency — but at a far lower cost per ounce.
Icelandic (Skyr) Plain Yogurt
Skyr, a traditional Icelandic cultured dairy product, is technically a soft cheese but consumed like yogurt. It’s ultra-thick, high in protein, and lower in sugar than many alternatives.
Costco occasionally stocks Icelandic-style plain yogurt, either under the Kirkland brand or as special imports. These are typically found in large multi-packs and are perfect for those seeking a protein-rich, filling snack.
Distinguishing Skyr From Greek Yogurt
While similar in texture, Skyr yogurt often contains even more protein and less fat than Greek yogurt. For fitness enthusiasts or those with high protein goals, this can be a valuable distinction.
Major Brands and In-House Options at Costco
Costco is known for offering a curated selection of products — so while you won’t find dozens of brands, the ones available are thoughtfully chosen for quality and value.
Kirkland Signature: Costco’s Trusted House Brand
The Kirkland Signature line dominates the yogurt section at most Costco warehouses. Known for competitive pricing and consistent quality, their plain yogurt tubs are often imported or produced in bulk under contract with reputable dairy manufacturers.
For example, the Kirkland Signature Greek Nonfat Plain Yogurt is manufactured in partnership with a well-known European producer, ensuring high standards in fermentation and freshness.
Key Benefits of Kirkland Plain Yogurts:
- Large 5- to 6-pound containers, ideal for families or meal prep
- Minimal ingredients — typically just milk and live cultures
- No artificial sweeteners or preservatives
- Extremely competitive price per ounce — often 30–50% less than grocery store equivalents
Other Brands You Might Find
While Kirkland is the most common, seasonal or regional Costco locations may carry:
- Chobani Plain Greek Yogurt — sold in multi-packs, especially around health-focused marketing campaigns
- Fage Total 0% or 2% — high-quality Greek yogurt occasionally available in larger tub sizes
- Dannon or Stonyfield Organic Plain Yogurts — sometimes found in organic sections or regional stores
However, availability fluctuates, so don’t rely on these brands being consistently in stock. The Kirkland Signature options remain the most reliable and cost-effective.
Nutritional Comparison: Plain Yogurt Varieties at Costco
To help you make an informed decision, here’s a breakdown of the nutritional content in popular Costco plain yogurt offerings (per 1 cup serving / 245g):
| Yogurt Type | Calories | Protein (g) | Fat (g) | Carbohydrates (g) | Sugar (g) | Notable Features |
|---|---|---|---|---|---|---|
| Kirkland Whole Milk Plain | 150 | 8 | 8 | 12 | 12 | Creamy texture, great for cooking |

| Kirkland Greek Nonfat | 120 | 23 | 0 | 6 | 5 | Highest protein, lowest sugar |
Note: Natural sugars in yogurt (lactose) are included in the sugar count. Unlike flavored yogurts, plain versions contain no added sugars — making them a healthier long-term choice.
Health Benefits of Choosing Plain Yogurt
Incorporating plain yogurt into your diet offers several science-backed benefits:
Rich in Probiotics for Gut Health
Plain yogurt is home to live active cultures like Lactobacillus and Bifidobacterium, which support a healthy gut microbiome. These good bacteria can aid in digestion, reduce bloating, and may even improve immune function.
Excellent Source of Protein for Satiety
Particularly in Greek and Icelandic styles, protein content helps keep you full longer, reducing between-meal snacking. This makes plain yogurt a favorite for breakfast or post-exercise recovery.
Supports Bone Health with Calcium and Vitamin D
Most plain yogurts at Costco are fortified with vitamin D and provide a significant percentage of your daily calcium needs — crucial for maintaining strong bones and preventing osteoporosis.
Natural Prebiotics
The lactose in milk acts as a prebiotic, feeding the beneficial bacteria in your gut. Combined with probiotics, this creates a synergistic effect for digestive wellness.
How to Use Plain Yogurt Beyond the Breakfast Bowl
One of the most compelling reasons to buy plain yogurt in bulk is its incredible versatility. Here are several creative and nutritious ways to use your Costco plain yogurt stash:
As a Base for Smoothies and Parfaits
Plain yogurt adds creaminess and protein to fruit smoothies without the sugar spike from flavored yogurts. Layer it in parfaits with granola, berries, and a drizzle of honey for a delicious, balanced snack.
In Savory Cooking and Sauces
Replace sour cream with plain Greek yogurt in:
– Tzatziki sauce
– Ranch dressing
– Baked potato toppings
– Curry bases (like in Indian raita)
It adds tang and protein while cutting saturated fat.
Marinades for Tender, Flavorful Meats
The mild acidity in yogurt helps tenderize proteins. Use plain yogurt as a base for marinades for chicken, lamb, or tofu. Combine with garlic, lemon juice, and spices for a healthy, flavorful preparation.
Recipe Tip: Greek Yogurt Chicken Marinade
Mix 1 cup of plain Greek yogurt, 2 minced garlic cloves, 1 tbsp lemon juice, 1 tsp paprika, salt, and pepper. Marinate chicken breasts for 2–4 hours before grilling or baking.
Baking Substitute for Higher-Fat Ingredients
Plain yogurt can replace ingredients like oil, butter, or buttermilk in muffins, cakes, and breads — resulting in moist, lower-fat baked goods.
For example:
– Replace 1 cup of sour cream with 1 cup of plain Greek yogurt in banana bread.
– Use plain yogurt instead of mayonnaise in cakes like chocolate mayo cake for moisture and richness.
DIY Yogurt Bowls and Meal Prep
Prep weekly yogurt jars with layers of plain yogurt, chia seeds, nuts, and frozen fruit. Thaw overnight, and you’ve got a ready-to-eat breakfast with no added sugars.
Is Costco’s Plain Yogurt Organic?
Currently, the standard Kirkland Signature plain yogurts sold at most locations are not labeled as organic. However, Costco occasionally carries organic plain yogurt under special promotions or in certain regional markets.
If you’re seeking organic options, keep an eye out for:
– Kirkland Signature Organic Whole Milk Plain Yogurt — offered in some warehouses
– Organic Valley or Stonyfield Organic multi-packs in the organic refrigerated section
Alternatively, consider joining Costco’s newsletter or using the Coscto app to check inventory and product details before visiting.
Storage and Shelf Life Tips
With such large containers, proper storage is essential to prevent waste.
Refrigeration Is Key
Always keep plain yogurt refrigerated below 40°F (4°C). Once opened, transfer to an airtight container if the original lid doesn’t seal well.
Shelf Life Expectations
- Unopened: 2–4 weeks past the printed sell-by date if stored properly
- Opened: Consume within 7–10 days for best quality
Note: While yogurt can sometimes be safely consumed after the expiration date, always check for:
– Sour or rancid odor
– Mold
– Excess liquid separation (a little is normal; a lot may indicate spoilage)
Can You Freeze Plain Yogurt?
Yes — but with caveats. Freezing plain yogurt can alter its texture, causing separation upon thawing. It’s best used for cooking or smoothies post-freezing, not for eating raw.
For optimal results:
– Freeze in ice cube trays for smoothie additions
– Thaw slowly in the refrigerator
– Stir well before use
Cost and Value: Why Costco Wins for Yogurt Buyers
Let’s compare the cost per ounce of Costco’s Kirkland Signature Greek Nonfat Plain Yogurt (5 lb / 80 oz tub) with grocery store brands:
| Product | Size | Price (Approx.) | Cost Per Ounce |
|——–|——|——————|—————-|
| Kirkland Signature Greek Nonfat, Costco | 80 oz | $9.99 | $0.125 |
| Chobani Plain Nonfat, Grocery Store | 32 oz | $6.99 | $0.218 |
| Fage Total 0%, Grocery Store | 32 oz | $7.49 | $0.234 |
By purchasing from Costco, you’re saving nearly 50% per ounce — especially powerful if you’re buying multiple tubs or using yogurt daily.
For families of four consuming 1 cup per person daily, you’d go through about one 5-pound tub every 10–12 days — making this a sustainable and economical choice.
What to Know Before You Buy
Before heading to Costco to pick up a tub of plain yogurt, consider these key tips:
Check Local Inventory Online
Not all Costco locations carry the same items. Use the Coscto website or app to search for “plain yogurt” and view availability at your nearest warehouse.
Look Beyond the Label
Even within “plain yogurt,” check the ingredient list. Stick to products with just:
– Milk
– Live active cultures
Avoid any with thickeners (like modified cornstarch), gelatin, or added sweeteners.
Consider Your Dietary Goals
- Trying to lose weight? Opt for nonfat or low-fat plain Greek yogurt.
- Following a keto diet? Whole milk plain yogurt provides healthy fats.
- Need high protein? Greek or Skyr-style options are best.
Eco-Friendly and Waste-Reducing Strategies
Bulk items like yogurt tubs can contribute to waste if not managed well. Here’s how to use your Costco plain yogurt sustainably:
– Repurpose empty tubs for storage, gardening scoops, or DIY craft containers
– Share with neighbors or friends if you can’t consume it in time
– Make labneh or strained yogurt — a delicious Middle Eastern cheese made by straining plain yogurt, extending usability
Final Verdict: Yes, Costco Carries Plain Yogurt — And It’s a Great Buy
To answer the original question: Yes, Costco absolutely carries plain yogurt — and not just in one form. You’ll typically find a range of types including whole milk, low-fat, nonfat, and Greek-style options, primarily under the trusted Kirkland Signature brand.
The value, quality, and versatility of Costco’s plain yogurt make it one of the best bulk dairy purchases available. Whether you’re building high-protein meals, looking for healthy snacks, or want a natural ingredient for cooking and baking, Costco’s plain yogurt delivers on all fronts.
So next time you’re shopping the warehouse aisles, don’t skip the dairy section. Grab a giant tub of plain yogurt and experience the perfect blend of nutrition, convenience, and savings. Your body — and your wallet — will thank you.
Does Costco Carry Plain Yogurt?
Yes, Costco carries plain yogurt at most of its warehouse locations. The availability of plain yogurt may vary depending on the region, store size, and current inventory, but plain varieties—such as non-fat, low-fat, and whole milk plain Greek yogurt—are commonly stocked. These options are typically offered in large multi-pack containers, aligning with Costco’s bulk-selling model, and are often from well-known brands like Kirkland Signature (Costco’s own label), Chobani, or Fage.
Customers looking for plain yogurt should check the refrigerated dairy section, where yogurt is organized by brand and type. The Kirkland Signature Organic Plain Greek Yogurt is a particularly popular and cost-effective choice among shoppers. Due to high turnover, stock may occasionally run out, especially in high-demand areas, so it’s a good idea to visit earlier in the week for the best selection.
What Types of Plain Yogurt Can I Find at Costco?
Costco typically offers a range of plain yogurt options catering to different dietary preferences and nutritional goals. Shoppers can commonly find plain Greek yogurt, which is known for its high protein content and thick texture. These are available in full-fat, 2% reduced-fat, and non-fat varieties. Some stores also carry organic options, such as Kirkland Signature Organic Plain Greek Yogurt, which is free from artificial additives and made with milk from cows not treated with rBST.
In addition to Greek-style, some Costco locations stock regular plain yogurt, which tends to be thinner and lower in protein compared to Greek versions. Customers may also find Icelandic-style plain yogurt, or skyr, which is similar to Greek yogurt but often even higher in protein. Availability of specific types and brands depends on seasonal supplies and warehouse distribution, so checking the product display or asking a store associate can help identify current offerings.
Is Kirkland Signature Plain Yogurt Available at All Costco Locations?
Kirkland Signature plain yogurt, especially the Organic Plain Greek Yogurt, is widely available at most Costco warehouses across the United States and Canada. As Costco’s in-house brand, Kirkland products are a staple in the dairy section, and the plain yogurt variant is a frequent restock item due to high consumer demand. However, availability may vary based on distribution and regional preferences, with some smaller or more remote warehouses offering limited quantities or rotating stock.
It’s worth noting that Kirkland Signature offers different yogurt varieties under various packaging sizes—commonly 5-pound tubs or multi-packs of smaller containers. The 5-pound tubs are ideal for families or those who use yogurt regularly in cooking, baking, or smoothies. To confirm local availability, shoppers can use the Costco website or app, which features store inventory lookup tools, or call their local warehouse directly before visiting.
How Does the Price of Plain Yogurt at Costco Compare to Other Retailers?
Plain yogurt at Costco is typically more cost-effective than at traditional grocery stores, especially when purchased in large quantities. Due to Costco’s bulk pricing model and low markup strategy on private-label items, the per-ounce cost of plain yogurt—particularly Kirkland Signature—is often significantly lower than comparable brands at supermarkets. For example, a 5-pound tub of Kirkland Organic Plain Greek Yogurt frequently offers a better value than buying multiple individual containers elsewhere.
This savings is particularly evident for families or individuals with high yogurt consumption, such as those following high-protein diets or using yogurt in meal prep. While non-members may see the upfront cost as high due to the large container size, members often report that the long-term value justifies the initial investment. Additionally, since Costco frequently offers promotions or bundles on dairy items, savvy shoppers can take advantage of even greater discounts during certain times of the year.
Can Non-Members Buy Plain Yogurt at Costco?
Non-members cannot regularly shop at Costco without paying a fee, but they do have limited options to purchase plain yogurt. One option is using a Costco gift card, which allows non-members to make purchases at the warehouse. Alternatively, non-members can accompany a Costco member into the store and let the member make the purchase. However, shopping independently at the door is not permitted for non-members.
Some people opt for a temporary membership or a free trial if offered, to make a one-time purchase. In select areas, Costco also operates standalone liquor or gas stations where membership is not always required, but this does not apply to warehouse grocery shopping. For those who don’t want a long-term commitment, becoming an affiliate member through certain credit cards or shopping with a friend regularly may be practical alternatives to access Costco’s yogurt selection.
Is Costco’s Plain Yogurt Suitable for Cooking and Baking?
Yes, Costco’s plain yogurt—especially Greek varieties—is excellent for cooking and baking due to its thick, creamy texture and neutral flavor. It can be used as a healthier substitute for sour cream, mayonnaise, or buttermilk in recipes such as dips, dressings, marinades, and baked goods. The high protein and fat content (depending on the variety) contribute to moist textures in muffins, cakes, and breads, making it a favorite among home cooks and meal preppers.
Kirkland Signature plain Greek yogurt, in particular, is praised for its consistency and lack of added sugars or flavors, which makes it ideal for savory dishes. It can also be used in breakfast bowls, smoothies, or as a base for homemade granola parfaits. Because it comes in large quantities, buying yogurt at Costco is especially convenient for people who frequently use it in recipes, meal prep, or for making labneh (strained yogurt cheese) at home.
How Long Does Plain Yogurt from Costco Last Once Opened?
Once opened, plain yogurt from Costco typically remains fresh for 7 to 10 days when stored properly in the refrigerator at or below 40°F (4°C). The large 5-pound tubs, while economical, require careful handling to prevent spoilage. It’s important to use clean utensils when scooping out yogurt to avoid introducing bacteria, and the container should be sealed tightly after each use to maintain quality and prevent odor absorption.
Unopened yogurt can last well beyond the printed “best by” date—often 1 to 2 weeks—if kept refrigerated. The shelf life varies slightly depending on whether the yogurt is regular, Greek, or organic, and on the specific formulation. Some shoppers prefer to portion the yogurt into smaller, airtight containers to extend usability and reduce the risk of contamination. Freezing is also an option for long-term storage, although it may alter the texture slightly upon thawing.
