In today’s fast-paced kitchens, the Instant Pot has transformed the way home cooks prepare meals. From fluffy rice to tender ribs, this multi-cooker does it all—but many users still struggle with one powerful yet underutilized feature: simmering. While most people rely on the Instant Pot’s pressure cook function, mastering how to set your Instant Pot to simmer opens up a world of delicate sauces, soups, stews, and braises that require gentle, consistent heat rather than high-pressure cooking. In this comprehensive guide, we’ll walk you through everything you need to know about setting your Instant Pot to simmer, including the proper settings, techniques, and best practices to get restaurant-quality results every time.
Understanding What Simmering Means on Your Instant Pot
Before diving into the steps, it’s crucial to understand what “simmering” actually refers to in the context of an Instant Pot. Unlike traditional stovetop simmering where liquid gently bubbles at around 180–205°F (82–96°C), the Instant Pot’s simmer function is a low, slow cooking method without pressure. It uses the Saute or Slow Cook settings at reduced heat levels to maintain a steady temperature ideal for developing flavors slowly and preventing scorching.
Simmering in the Instant Pot allows:
- Thickening sauces without boiling too rapidly
- Braising meats gently for fall-off-the-bone tenderness
- Infusing herbs and spices into broths and soups
- Cooking delicate dishes like risotto or custards safely
The Difference Between Pressure Cooking and Simmering
Many users confuse the Instant Pot’s high-pressure mode with simmering. Here’s the key difference:
- Pressure Cooking: Uses sealed pressure and high temperatures (about 235–250°F or 113–121°C) to cook food quickly. Ideal for beans, stews, and tough cuts of meat.
- Simmering: Applies low, steady heat at or near the boiling point of water, promoting gentle cooking. Best for recipes where flavor development and texture control are essential.
So while pressure cook might get dinner on the table faster, simmering ensures depth, complexity, and refinement—perfect for gourmet-style comfort food.
How to Set Instant Pot to Simmer: Step-by-Step Instructions
The way you set your Instant Pot to simmer depends on your model and the recipe’s specific requirements. Most newer Instant Pot models (Duo, Lux, Vortex, etc.) offer several options, but the Saute function and Slow Cook mode are the most commonly used for simmering.
Method 1: Using the Saute Function to Simmer (Manual Control)
The Saute setting is one of the most effective tools for simmering liquids. Despite the name, it can also be used to keep food warm or gently reduce sauces. Here’s how:
Step 1: Select the Saute Button
Press the Saute button on your Instant Pot. A default high heat level will engage—this is too hot for simmering.
Step 2: Adjust to Less or Low Heat
While the Saute mode is running, press the Adjust button repeatedly until it displays “Less” or “Low”” (depending on your model). This reduces the temperature to approximately 220°F (104°C), which is close to a true simmer.
Step 3: Add Your Ingredients and Stir
Add your liquids—such as broth, wine, or tomato sauce—and any other ingredients you’d like to simmer. Stir occasionally to prevent sticking, especially if you’re cooking starchy dishes like polenta or sauces with cream.
Step 4: Monitor and Simmer
Allow the mixture to reach a gentle bubble. You should see small, consistent bubbles breaking the surface, but no vigorous rolling boils. If it starts boiling too hard, press Cancel and let it cool a bit, or partially cover with the lid (vented position).
Tip: Use the “Keep Warm” function after simmering to maintain temperature for serving, especially during entertaining.
Method 2: Using Slow Cook Mode for Long Simmering
If you’re preparing a dish that needs hours of low-temperature cooking, the Slow Cook setting is ideal. It mimics a traditional crockpot but with more control.
Step 1: Press the Slow Cook Button
Select the Slow Cook button on your Instant Pot. By default, it begins on the “Normal” heat setting for 4 hours.
Step 2: Adjust Cooking Time and Heat Level
Press Adjust to cycle through Low, Normal, and High settings. For simmering, choose Low for the gentlest heat. Then, adjust the time using the +/- buttons to set anywhere from 30 minutes to 24 hours.
Step 3: Cover and Let Simmer
Place the lid on the Instant Pot, but ensure the steam release valve is in the venting position—slow cooking does not use pressure. Let the contents cook slowly, stirring occasionally if needed.
Best For: Braised short ribs, vegetable curries, hearty chilis, or slow-simmered tomato sauce.
Method 3: Combining Pressure Cook and Simmer (For Advanced Recipes)
Some recipes, like beef bourguignon or coq au vin, start with sauteing, move into pressure cooking to tenderize meat, and then finish with simmering to reduce sauce and blend flavors.
Example Sequence:
- Saute vegetables and sear meat using “Saute” mode (normal or more setting)
- Pressure cook with broth and wine for 35 minutes
- Release pressure manually
- Switch to “Saute – Less” and simmer uncovered for 15–20 minutes to thicken sauce
This hybrid approach gives you speed, flavor, and texture in one seamless workflow.

Bottom Line: For consistent simmering results, choose a model with the Adjustable Saute function and Slow Cook mode. The Duo, Ultra, and Duo Crisp are all excellent choices.
Top Tips for Successful Simmering in Your Instant Pot
Even with the right settings, a few simple techniques can make or break your simmered dish. Follow these expert tips to perfect the process:
1. Don’t Overfill the Pot
For simmering, keep contents below the ½ fill line. This helps prevent boil-overs and allows enough space for evaporation—critical when reducing sauces.
2. Stir Occasionally
Unlike pressure cooking, where stirring isn’t needed, simmering benefits from gentle stirring every 10–15 minutes. This promotes even heat distribution and prevents scorching on the bottom.
3. Leave the Lid Off or Vented
When simmering with Saute mode, either remove the lid completely or place it slightly ajar (vented). This facilitates evaporation and prevents pressure buildup.
4. Use a Lid as a Splatter Guard (Optional)
If you want to minimize mess while still allowing steam to escape, you can cover the pot with a silicone splatter guard or tilt the glass lid just enough to vent.
5. Monitor Temperature with a Thermometer
For precision cooking (like making custards or delicate reductions), consider inserting a digital thermometer. A true simmer sits between 185°F and 205°F—anything over 212°F is boiling.
6. Add Alcohol or Dairy Slowly
Wine, cream, and other additives can curdle or evaporate too quickly if introduced to high heat. Add them during the simmer phase and stir gently. Use low Saute (Less) setting to avoid splattering or separation.
7. Stop the Cook Process Promptly
To avoid over-reduction or scorching, press Cancel when your dish is done. The residual heat will keep it warm for serving.
Best Recipes to Simmer in Your Instant Pot
Simmering unlocks the potential for nuanced, slow-developed flavors. Here are some standout dishes that benefit from this technique:
1. Marinara or Bolognese Sauce
After pressure-cooking onions, garlic, and meat, use Saute – Less to simmer the sauce for 20–30 minutes. This deepens the flavor and thickens the texture without burning the bottom.
2. Dutch Baby Pancake or Clafoutis
Use Slow Cook on Low for 1.5–2 hours. The gentle heat allows custard-based batters to puff and set evenly.
3. Lentil Soup or Vegetable Stew
Sauté vegetables first, then simmer on Low for 3–4 hours. This draws out sweetness and melds herbs and spices naturally.
4. Rice Pudding or Oatmeal
Simmer milk-based grains gently to avoid boiling over and scorching. Try the Slow Cook Low setting with a timer for foolproof breakfasts.
5. Reduction Sauces (e.g., Balsamic Glaze)
Combine vinegar, sugar, and herbs. Simmer on “Saute – Less” uncovered, stirring occasionally, until reduced by half and syrupy.
Recipe Hack: Always taste and season at the *end* of simmering. As liquids reduce, salt and seasoning concentrate, so adjust at the end to get it perfect.
Troubleshooting Common Simmering Issues
Even experienced users run into problems. Here’s how to solve the most common simmering hiccups:
Issue 1: Food Is Burning on the Bottom
Solution: This often happens when the heat is too high or when starchy ingredients (like rice or tomatoes) sit too long. Use “Saute – Less” instead of default Saute, stir frequently, and consider adding a splash more liquid. Also, scrape the bottom regularly with a wooden or silicone spatula.
Issue 2: Simmer Is Too Vigorous
Solution: If your liquid is boiling rather than simmering, press “Adjust” to lower the Saute heat or cancel and restart on “Less.” You can also unplug the Instant Pot and return later if it’s a “Keep Warm” issue.
Issue 3: Not Thickening Enough
Solution: If your sauce isn’t reducing, make sure the lid is off and steam can escape. Increase the simmer time, but keep an eye on liquid levels. For faster thickening, mix a slurry of cornstarch and water, then whisk it in during the final 5 minutes.
Issue 4: Slow Cook Doesn’t Feel Hot Enough
Solution: The “Low” setting on Slow Cook is designed to maintain around 190°F, which is a very low simmer. If you want a more active simmer, switch to “Normal” or use Saute – Less for better control.
Comparing Instant Pot Simmer to Stovetop Simmering
It’s natural to wonder: Is simmering in an Instant Pot as effective as doing it on the stove?
| Factor | Instant Pot Simmer | Stovetop Simmer |
|---|---|---|
| Temperature Control | Consistent auto-setting (if using Low) | Manual flame adjustment (more variation) |
| Hands-off Time | High – Set and forget | Moderate – Requires monitoring |
| Risk of Burning | Higher if not stirred (especially Saute mode) | Lower with vigilant stirring |
| Evaporation Rate | Slower unless lid is off | Faster when uncovered |
| Surface Area for Reduction | Smaller (cylindrical pot) | Larger (wide pans preferred) |
| Best For | Beginner cooks, small batches, multitasking | Large reductions, professional control |
Verdict: The Instant Pot is excellent for gentle simmering when you need convenience and consistency. But for large-volume reductions or advanced sauce work, a wide skillet or Dutch oven on the stove will offer better evaporation and control.
Cleaning and Maintenance After Simmering
Simmering sauces or starchy dishes can leave residue on the inner pot, especially around the edges. To keep your Instant Pot in top shape:
- Let the pot cool before washing
- Soak the inner pot in warm, soapy water if sauce has stuck
- Use a non-abrasive sponge—avoid steel wool
- Wipe the sealing ring and exterior with a damp cloth
- Never immerse the base in water
Proper care ensures your Instant Pot will continue to simmer smoothly for years.

Now that you know how to set your Instant Pot to simmer, it’s time to experiment. Start with a simple tomato sauce, try a slow-simmered soup, or reduce a balsamic glaze for your next salad. The more you practice, the more you’ll appreciate how this simple function can elevate your home cooking.
Remember: great flavor is built over time—and simmering is how you do it, one gentle bubble at a time.
What does the simmer function do on an Instant Pot?
The simmer function on an Instant Pot is designed to gently cook food at a consistent, low temperature, typically just below the boiling point of water. This setting mimics the traditional stovetop simmering method, allowing flavors to meld slowly without aggressive boiling that could break down delicate ingredients. It’s ideal for preparing sauces, soups, stews, and dishes that require slow, even heating like porridge or braised meats.
Unlike the pressure cooking function, the simmer function operates at normal atmospheric pressure, giving you greater control over the cooking process. It enables you to reduce liquids gradually, maintain a steady heat, and avoid scorching, particularly useful for recipes that need extended cooking times without pressure. The function is especially valuable for finishing dishes started under pressure or for cooking recipes traditionally prepared on the stove.
How do you access the simmer function on newer Instant Pot models?
On newer Instant Pot models like the Duo Crisp, Vortex, or Lux series, the simmer function is often labeled directly and accessible via the control panel. Simply press the “Simmer” button to activate the setting. These models typically allow you to adjust the temperature and duration, offering preset options for low, medium, or high simmer, depending on your recipe’s requirements.
If your model doesn’t have a dedicated “Simmer” button, you can use the “Slow Cook” function set to high or “More” mode as a substitute for a gentle simmer. Additionally, some models let you use the “Manual” or “Pressure Cook” function with zero pressure and a longer time, followed by natural release, to achieve a simmer-like effect. Always consult your model’s manual to determine the most accurate settings available.
Can you use the pressure cooking function to simulate a simmer?
Yes, the pressure cooking function can be adapted to simulate a simmer, but with important distinctions. You can set the Instant Pot to cook at high pressure for a short time, then quickly release the pressure and allow the dish to continue cooking at a lower temperature in the “Keep Warm” mode. This approach works well for transitioning from pressure-cooked dishes to a slow, flavor-developing simmer phase.
However, true simmering requires no pressure and a lower, steady temperature—usually between 185°F and 205°F (85°C–96°C). Using the pressure cook function won’t precisely replicate these conditions. For best results, rely on the dedicated simmer or slow cook setting if available. Otherwise, manually monitor the pot after releasing pressure to avoid overcooking or drying out your dish during the post-pressure simmering stage.
How long should you simmer food in an Instant Pot?
The duration for simmering in an Instant Pot depends on the type of food and recipe goals. Generally, simmering times can range from 10 to 45 minutes for finishing sauces or soups, while heartier dishes like stews or braised meats may benefit from 1 to 4 hours of gentle cooking. Always refer to your recipe, but use the pot’s adjustability to fine-tune timing based on desired consistency and flavor development.
Over-simmering can lead to reduced liquid, overly soft textures, or even scorching, especially if unattended. It’s advisable to set a timer and check your food periodically, particularly during longer simmer sessions. Most Instant Pot simmer functions include a default time, but you can customize it using the “+” and “–” buttons. If uncertain, start with a shorter time and extend as needed to achieve the perfect texture.
What is the temperature range of the Instant Pot’s simmer function?
The simmer function on an Instant Pot generally maintains a temperature range between 185°F and 205°F (85°C–96°C), closely mimicking a traditional stove-top simmer. This low, controlled heat prevents rapid boiling while ensuring food continues to cook gently, preserving texture and allowing flavors to deepen over time. Some models may vary slightly in exact output, but all aim to stay just below the boiling point of water (212°F or 100°C).
This precise temperature control makes the simmer function ideal for reducing sauces, cooking custards, or preparing delicate broths without curdling or scorching. Because it operates at a consistent heat, it reduces the need for constant stirring. However, it’s still wise to check occasionally, particularly when cooking thick or starchy foods, to prevent sticking or uneven cooking at the pot’s base.
Do you need to cover the Instant Pot when using the simmer function?
Yes, it is recommended to cover the Instant Pot with the lid during the simmer function to maintain consistent temperature and prevent excessive evaporation. While the pot doesn’t seal under pressure in this mode, the glass lid—often used during slow or sauté/simmer cycles—helps retain moisture and heat, contributing to even cooking. If your model includes a vented lid, ensure the steam valve is in the “vented” position to allow small amounts of steam to escape safely.
Leaving the pot uncovered may cause liquids to reduce too quickly and increase the risk of splattering or uneven heating. It can also make it difficult to maintain the desired simmer temperature, especially in cooler environments. Always use oven mitts when handling the lid, as it and the pot can become hot during extended simmering. Proper covering enhances safety and improves cooking outcomes.
Can you leave the Instant Pot unattended while it’s simmering?
While the Instant Pot is designed to be safe and reliable, it’s generally not recommended to leave it completely unattended during the simmer function, especially for extended periods. Although the appliance has safety features like automatic shut-off and overheat protection, prolonged simmering of thick or starchy foods may still pose a risk of burning or sticking at the bottom, which could trigger the “burn” warning or affect food quality.
For optimal results and safety, periodic checks are advisable. Stirring every 20–30 minutes helps prevent scorching and ensures even cooking. If you must step away, keep the duration short and set a timer to remind yourself. When used responsibly, the simmer function offers hands-off convenience, but attentive monitoring ensures your dish turns out perfectly without unexpected issues.
