Cooking a pie in the microwave might sound unconventional to traditional bakers, but in today’s fast-paced world, convenience often wins. Whether you’re in a rush, your oven is broken, or you’re serving a last-minute dessert, the microwave offers a surprisingly efficient way to enjoy a warm, delicious pie. But how long does it take to cook a pie in the microwave? The answer isn’t one-size-fits-all—it depends on the type of pie, its size, ingredients, and your microwave’s wattage. In this comprehensive guide, we’ll break down everything you need to know about microwaving pies, including cooking times, safety tips, best practices, and how to avoid common mistakes.
Why Microwave a Pie?
While baking a pie in the oven delivers golden crusts and deep flavors, microwaving offers several practical benefits:
- Speed: Ovens can take up to an hour just to preheat—microwaves deliver heat instantly.
- Energy efficiency: Microwave ovens consume less electricity than conventional ovens.
- Convenience: Ideal for reheating a slice or preparing a pre-made pie quickly.
- Accessibility: Available in almost every kitchen, dorm room, or workplace.
Although microwaves don’t produce the same browning or crisping effect as ovens, they are excellent for heating and softening the filling of a pie. But when can microwaving work for full pie cooking, and how does it affect taste and texture?
Types of Pies and Microwave Suitability
Not every pie is designed to be cooked solely in the microwave. Understanding your pie’s composition is key to ensuring success.
Fruit Pies
Fruit pies like apple, cherry, or blueberry are among the easiest to microwave. Since the fruit filling is already soft or semi-cooked (in pre-made pies), microwaving primarily warms the filling and slightly softens the crust.
Note: If you’re cooking a raw fruit pie from scratch, microwaving may not fully set the crust or thicken the juice. For best results, pre-bake the crust or pair microwaving with short oven finishing.
Cream and Custard Pies
Cream pies such as banana cream or pumpkin pie are ideal for microwaving in moderation. These pies are typically pre-cooked and refrigerated, so microwaving gently warms them without overcooking. However, caution is needed—milk-based fillings can easily curdle or separate if heated too quickly.
Meat and Savory Pies
Meat pies, shepherd’s pie, or pot pies can be safely microwaved, but require longer exposure due to dense fillings. The risk of uneven cooking increases here, so periodic stirring or rotating is essential.
Pastries and Hand Pies
Smaller pastries like handheld turnovers, empanadas, or pop tarts are excellent candidates for microwave heating. They generally heat through in under 2 minutes and retain their shape better than full-sized pies.
Factors That Affect Microwave Cooking Time
Before you start, understand that the exact time to cook a pie in the microwave depends on several variables.
Microwave Wattage
This is the most critical factor. Most microwaves range from 600 to 1200 watts. Higher wattage means faster heating. As a rule of thumb:
- 600–700 watts: Slightly longer cooking time (add 20–30 seconds)
- 800–900 watts: Standard timing applies
- 1000+ watts: Reduce time slightly to avoid overheating
Tip: Check your microwave’s wattage in the user manual or on the back panel. If unavailable, perform a water test: microwave 1 cup of water and time how long it takes to boil. Under 2 minutes = high wattage (1000+ W).
Size and Thickness of the Pie
A full 9-inch pie takes significantly longer than a single slice. Think about volume and density. A thick double-crust fruit pie will need more time than a shallow cream pie.
Starting Temperature
Is your pie refrigerated, frozen, or at room temperature? This directly impacts cooking time:
- Frozen pie: Add 1–2 minutes per slice
- Refrigerated pie: Standard time applies
- Room-temperature pie: Reduce time by 20–30 seconds
Crust Type
Some crusts (like crumble or biscuit-top shepherd’s pie) hold up better in the microwave, while traditional flaky pastry can become soggy due to trapped steam.
Estimated Microwave Cooking Times by Pie Type
Here’s a detailed breakdown for common pie types. These times assume an 800–1000 watt microwave and a single serving (about 1/6 of a 9-inch pie):
| Pie Type | Refrigerated (Time) | Frozen (Time) | Notes |
|---|---|---|---|
| Apple Pie (slice) | 1.5–2.5 minutes | 3–4 minutes | Cover with paper towel; rotate halfway |
| Pumpkin Pie (slice) | 1–2 minutes | 2.5–3.5 minutes | Low power setting recommended |
| Blueberry Pie (slice) | 2–3 minutes | 3–4 minutes | May need stirring if juice thickens |
| Meat Pie (individual) | 3–4 minutes | 5–6 minutes | Stir or flip if possible |
| Banana Cream Pie (slice) | 45 seconds–1.5 minutes | 2–2.5 minutes | High risk of curdling; use low heat |
| Shepherd’s Pie (serving) | 4–5 minutes | 6–7 minutes | Stir well after cooking |
Important: These are starting points. Always check for doneness and adjust accordingly.
Step-by-Step Guide to Microwave Pie Cooking
Follow these proven steps to safely and effectively cook or reheat your pie in the microwave.
1. Prepare Your Pie
Remove foil, plastic wrap, or any non-microwave-safe container. Transfer to a microwave-safe dish if necessary. For single slices, keep them on a plate.
Tip: If reheating a frozen whole pie, consider thawing it in the refrigerator for 1–2 hours first for even heating.
2. Cover the Pie
Always cover your pie with a **moist paper towel** or microwave-safe lid. This prevents splatters and keeps the crust from drying out. However, avoid sealing it tightly—steam needs to escape to prevent sogginess.
3. Use Medium Power for Better Results
Set the microwave to 50% to 70% power instead of full blast. This allows heat to penetrate slowly, avoiding hot spots and boiling fillings. For example:
– Apple pie: 70% power for 2 minutes
– Pumpkin pie: 50% power for 1.5 minutes
– Meat pie: 60% power for 4 minutes
4. Rotate or Stir Midway
After half the cooking time, pause the microwave and rotate the dish. If safe, gently stir the filling (especially for shepherd’s pie or fruit pies with loose juice) to ensure even heat distribution.
5. Check for Doneness
Probe the center with a clean knife or toothpick. The filling should be steaming hot (above 165°F or 74°C for safety). Crust should be warm, not cold or rubbery.
Warning: Overheating can cause fillings to explode or crusts to harden. If the pie is not fully hot, continue in 15–30 second increments.
6. Let It Rest
Allow the pie to sit for 1–2 minutes after microwaving. This helps the temperature even out and prevents burns from scalding filling.
Can You Cook a Raw Pie in the Microwave?
Technically, yes—but carefully. While microwave ovens excel at heating, they don’t roast or brown like conventional ovens. However, with proper preparation, you can bake certain raw pies—particularly mug pies or small portions.

Microwave vs. Oven: Pros and Cons
While microwaving a pie saves time, it sacrifices texture and visual appeal.
Pros of Microwave Cooking
– Speed: A pie slice heats in under 3 minutes.
– Minimal mess: Less oil splatter or juice overflow.
– Energy savings: Much lower kilowatt usage than ovens.
– Portability: Great for quick meals at work or school.
Cons of Microwave Cooking
– No browning: Crusts won’t crisp or develop golden color.
– Sogginess: Steam softens pastry, making it chewy.
– Uneven heating: Hot spots and cold centers are common.
– Texture loss: Custards can curdle; fruit can become mushy.
Common Mistakes to Avoid
Even with simple instructions, people often make avoidable errors when microwaving pies. Here’s how to sidestep them.
1. Using High Power for the Entire Duration
Full power from start to finish often leads to overflow or curdling. Always begin at medium power, especially with custard, cream, or meat pies.
2. Not Covering the Pie
An uncovered pie will splatter filling across the microwave walls, creating a cleaning nightmare. Use a paper towel or microwave-safe cover every time.
3. Overheating Small Portions
A single slice only needs 1–2 minutes. Over-microwaving can destroy textures and make the dish unpleasantly hot.
4. Ignoring the Standing Time
Letting the pie rest after microwaving lets heat distribute evenly and prevents burns. Skipping this step means biting into molten filling while the edges are lukewarm.
5. Microwaving Metal or Non-Safe Dishes
Never microwave foil pans, metal-rimmed plates, or containers not labeled “microwave safe.” This can cause sparks or damage your appliance.
Tips for Better Microwave Pie Results
Enhance the quality of your microwaved pie with these expert tips.
Add a Crisping Touch
To restore crunch, use a toaster oven or air fryer for 2–3 minutes after microwaving. This crisps the crust without overcooking the filling.
Drain Excess Juice
If fruit pie filling is too runny, let it sit uncovered for a moment before microwaving or blot excess juice with a paper towel after heating.
Use the Right Plate
Ceramic plates retain heat better than plastic. A pre-warmed plate can help keep your pie hot longer.
Stir or Mix Before Serving
This is especially helpful for pies with layered ingredients (like shepherd’s pie). Stirring ensures every bite is flavorful and evenly heated.
Add a Topping
A dollop of whipped cream, ice cream, or a sprinkle of cinnamon can elevate a microwaved pie instantly. The contrast of hot pie and cold topping is delicious.
Safety Considerations
Microwaving food isn’t inherently dangerous, but best practices should be followed.
Temperature Safety
Reheated pies—especially those with meat, dairy, or eggs—must reach an internal temperature of at least 165°F (74°C) to kill harmful bacteria. Use a food thermometer if unsure.
Burn Prevention
Filling heats quickly and can become superheated—hotter than boiling point without visible bubbles. Scoop a small portion first or stir before eating to prevent sudden steam bursts.
Handling Frozen Pies
Avoid microwaving large frozen pies whole. The exterior may overcook while the center remains frozen. Instead, thaw first or use a convection microwave with defrost settings.
Environmental Impact: Microwaving vs. Baking
Microwaves use up to 80% less energy than conventional ovens. According to the U.S. Department of Energy, cooking a meal in a microwave emits significantly fewer greenhouse gases. For occasional pie heating, the microwave is the eco-friendlier choice—especially when serving one or two people.
When Should You Avoid the Microwave?
Despite its conveniences, there are times when microwaving a pie simply isn’t ideal:
- Whole pies from scratch: Ovens provide even heat and proper browning.
- Dessert presentation: Microwaved pies lack the golden hue and flaky crust that impress guests.
- Texture-sensitive recipes: Meringue-topped pies or delicate puff pastry desserts suffer in microwaves.
In these cases, stick with conventional baking for the best culinary results.
The Verdict: How Long Does It Take?
So, how long does it take to cook a pie in the microwave? The short answer: anywhere from 45 seconds to 7 minutes, depending on size, type, and starting temperature.
– Single slice of fruit pie: 1.5–3 minutes
– Cream pie slice: 45 seconds–2 minutes
– Individual meat pie: 3–6 minutes
– Whole frozen pie: 6–10 minutes (in 2-minute intervals)
Always start conservatively and use lower power levels to avoid mistakes. With the right techniques, your microwave can deliver a satisfying, warm pie in record time—perfect for those unexpected cravings or hectic schedules.

Can you cook a pie in the microwave?
Yes, you can cook a pie in the microwave, although the results differ from traditional oven baking. Microwaves heat food quickly by exciting water molecules, making them ideal for reheating or partially cooking pies. While a microwave won’t give you the flaky, golden crust that an oven provides, it’s a convenient option for those seeking speed and simplicity. Pre-made pies, frozen pies, or even simple homemade fillings can be prepared this way, especially if convenience outweighs the desire for perfection.
However, there are some limitations. The crust may become soft or soggy, particularly the bottom, due to steam buildup during cooking. For best results, it’s often recommended to combine microwave cooking with a brief oven finish, or to use a microwave-safe crisping sleeve or tray. It’s also crucial to monitor cooking time to prevent overheating, which can cause fillings to bubble over or the pie to dry out. Microwaving works best for fruit pies, custard pies, or quick desserts where crust texture is less critical.
How long does it take to microwave a frozen pie?
A standard-sized frozen pie typically takes between 5 to 8 minutes to heat in the microwave, depending on wattage and pie composition. For an 800- to 1200-watt microwave, start with 5 minutes on high power and check the internal temperature. If the center is still cold, continue heating in 30-second increments until the pie is thoroughly warmed. To avoid a rubbery or uneven texture, allow the pie to rest for 1–2 minutes after microwaving, so heat distributes evenly.
The type of filling also affects cooking time. Fruit pies, with higher moisture content, generally heat faster than meat or dense custard pies. It’s advisable to cover the pie with a microwave-safe lid or vented plastic wrap to prevent splatters and retain moisture. You may want to rotate the dish halfway through for even heating, especially if your microwave has hot spots. For a more satisfying texture, consider transferring the pie to a toaster oven or regular oven for 3–5 minutes after microwaving to crisp the crust.
What is the best way to microwave a homemade pie?
When microwaving a homemade pie, it’s best to partially bake the crust first if possible. Start by blind-baking the bottom crust for 10–15 minutes in an oven to prevent sogginess. After adding the filling, microwave the pie on medium-high power (70% power) for 6–10 minutes, depending on size and filling type. Use a microwave-safe glass or ceramic dish, and cover loosely with a microwave-safe cover or paper towel to contain spills and maintain moisture.
High-power microwaving can cause fillings to explode or create uneven cooking, so using medium-high power is crucial for gentle, thorough heating. For fruit pies, stir the filling halfway through if possible (if not in a closed crust), and test for doneness by inserting a knife into the center—the knife should come out hot. Let the pie stand for a few minutes after cooking to allow thickening, especially for custard or cream fillings. For optimal results, finish with a short broil or oven bake to brown the top.
Can you reheat a baked pie in the microwave?
Yes, you can reheat a previously baked pie in the microwave, making it a quick way to enjoy leftovers. Reheating time varies based on pie size and filling, but generally takes 1.5 to 4 minutes on medium power. Smaller slices need about 1.5 to 2 minutes, while whole pies may require 3 to 4 minutes, with pauses to check temperature. For even warming, use 50–70% power to avoid overheating the edges while the center remains cool.
To preserve texture, place a damp paper towel over the slice before microwaving to retain moisture and prevent drying. This is especially helpful for custard or cream pies. For fruit pies, you can add a sprinkle of water or cover loosely to keep the crust from becoming tough. If a crisp texture is desired, consider finishing the reheated slice in a toaster oven or air fryer for 2–3 minutes. Always allow the pie to rest for a minute after microwaving to stabilize internal temperature.
Does microwaving a pie affect its taste and texture?
Microwaving a pie can significantly affect both taste and texture compared to oven baking. Because microwaves heat by exciting water molecules, the result is often a softer, sometimes rubbery crust that lacks the flaky crispness achieved in an oven. The filling may also cook unevenly, leading to pockets of overheated areas and cold spots. Additionally, delicate toppings like meringue or streusel may collapse or become chewy, reducing visual appeal.
However, the flavor of the filling is generally well-preserved, especially in fruit or chocolate pies, as the core ingredients are heat-stable. Some people even prefer the faster cooking method for convenience. To minimize texture issues, using microwave-safe crisping trays or combining microwave heating with a short oven finish can help restore some crispness. While microwaving won’t replicate the gourmet texture of a slow-baked pie, it can still provide a satisfying, warm dessert in a fraction of the time.
Are there safety concerns when microwaving a pie?
While microwaving a pie is generally safe, there are a few precautions to take. One common issue is “thermal runaway,” where the filling becomes extremely hot while the crust feels only warm. This can cause burns if you bite into the pie too quickly. Always test the temperature carefully, especially with custard, cream, or fruit fillings that retain heat well. Avoid using metal pans or foil, which can spark and damage the microwave.
Additionally, sealed pies or those with thick crusts may build up internal steam pressure and burst during or after cooking. To prevent this, vent the top crust slightly or use a pie with a pre-cut vent. Covering the pie with a microwave-safe lid or paper towel not only prevents splatters but also reduces the risk of overheating. Always use oven mitts when removing the dish, as the container may become very hot. Finally, ensure your microwave is clean to avoid smoke or fire from spilled fillings.
How can you improve the crust when microwaving a pie?
Improving the crust when microwaving a pie requires a few strategic steps. First, pre-baking the crust slightly in an oven before adding filling helps create a moisture barrier and reduces sogginess. Using a microwave-safe crisping sleeve or browning dish can also make a significant difference—these specialized tools absorb microwave energy and get hot, helping to crisp the bottom and sides of the crust. Additionally, placing a paper towel under the pie can absorb excess steam.
Another technique is to microwave the pie just until the filling is hot, then transfer it to a toaster oven or air fryer for 3–5 minutes to brown and crisp the top. You can also lightly brush the top crust with butter or egg wash before microwaving to enhance browning, though this works better with a follow-up oven step. For frozen pies, consider thawing slightly before microwaving to allow more even heating and prevent the crust from becoming tough on the outside while the inside remains cold.
