Yes, you can use an Instant Pot as a slow cooker, though you need to adjust the heat settings to “Normal” or “More” and use a glass lid for the best results.
Kitchen counter space is valuable real estate. You likely want to combine appliances to save room, and the promise of a multi-cooker is tempting. The idea that a single stainless steel pot can replace a heavy ceramic crock is appealing for anyone trying to declutter. However, the switch isn’t always seamless.
Pressure cookers and slow cookers transfer heat differently. If you treat them exactly the same, you might end up with undercooked carrots or a sauce that never thickens. Understanding the mechanics behind the heating element helps you adapt your favorite recipes without ruining dinner.
Can I Use An Instant Pot As A Slow Cooker? Realities & Adjustments
The short answer is yes, but with caveats. When people ask, “can I use an Instant Pot as a slow cooker?” they often assume the “Slow Cook” button acts exactly like a Crock-Pot. It does not. A traditional slow cooker heats from the bottom and the sides, surrounding the heavy ceramic insert with steady, radiant heat. This creates a thermal mass that holds temperature very well.
In contrast, an Instant Pot has a heating element only at the bottom. The stainless steel inner pot conducts heat fast but loses it fast too. It doesn’t hold heat like ceramic. Because the heat source is concentrated at the bottom, scorching can happen if the liquid isn’t sufficient, and the sides of the pot might be cooler than the base. You must modify your expectations and your settings to get a tender pot roast.
Why The “Low” Setting Isn’t What You Think
The biggest mistake new users make involves the temperature buttons. On a standard slow cooker, “Low” usually stabilizes around 190°F to 200°F, while “High” hits closer to 300°F (though they often stabilize at the same max temp, just at different speeds). The Instant Pot naming convention is different and often confuses home cooks.
The “Low” or “Less” setting on an Instant Pot is more like a “Keep Warm” function. It rarely gets hot enough to cook raw meat safely or break down collagen in tough cuts. If you set your pressure cooker to “Low” for 8 hours, you might come home to raw food. You almost always need to use “Normal” (Medium) or “More” (High) to mimic the traditional experience.
Comparing The Heating Logic
This table breaks down the fundamental differences between the two appliances so you can adjust your cooking times correctly.
| Feature | Traditional Slow Cooker | Instant Pot Slow Cook Mode |
|---|---|---|
| Heat Source | Wrap-around elements (bottom & sides) | Bottom heating element only |
| Pot Material | Thick Ceramic/Stoneware (High retention) | Thin Stainless Steel (Fast conduction) |
| “Low” Setting | ~190°F–200°F (Cooks food slowly) | ~170°F–180°F (More like Keep Warm) |
| “High” Setting | ~300°F (Cooks food fast) | ~200°F–210°F (Similar to standard Low) |
| Moisture Loss | Low (if lid fits well) | Very Low (if using pressure lid) |
| Risk of Burning | Low (heat is diffused) | Medium (hot spot on bottom) |
| Startup Speed | Slow ramp-up | Fast ramp-up |
Setting Up Your Instant Pot For Slow Cooking Success
You cannot simply dump ingredients in, press a button, and walk away. A few tactical changes will ensure your meal cooks evenly. The default settings on your pressure cooker are designed for speed, so you have to manually force it to act like a slow vessel.
Choose The Right Temperature Mode
Ignore the labels “Less”, “Normal”, and “More” if you are thinking about quantity. Think of them as temperature tiers.
- Less: Approximately 170°F. Do not use this for cooking raw meat. It is suitable for keeping dip warm or keeping a finished soup hot during a party.
- Normal: Approximately 190°F–200°F. This is your target for most standard slow cooker recipes that call for “Low” on a Crock-Pot. It mimics the gentle simmer needed for stews.
- More: Approximately 210°F or higher. This corresponds to the “High” setting on a traditional device. Use this if you are short on time or cooking dense root vegetables.
The Lid Situation: Pressure vs. Glass
The standard pressure lid that comes with your IP is insulated and heavy. If you use it for slow cooking, you must leave the vent open. However, even with the vent open, it locks in too much moisture and hides the food from view. Because the stainless steel pot doesn’t radiate heat from the sides, the top of your food can remain too cool if you use the heavy pressure lid.
Buying a tempered glass lid with a steam vent is a smart move. This allows you to see the simmer and lets excess liquid evaporate slightly, which helps thicken sauces. If you don’t have one, you can use a standard pot lid from your cookware set if it fits the rim securely.
Recipe Adjustments For The Stainless Steel Pot
Recipes written for ceramic pots rely on that side-wall heat. When you move that recipe to an Instant Pot, the heat comes strictly from below. This changes how ingredients behave.
Liquid Ratios Matter
In a standard slow cooker, some evaporation occurs over 8 hours. In an Instant Pot, especially if you use the standard lid, evaporation is near zero. This sounds good, but it often results in watery, flavorless gravy. You should reduce added liquids—like broth or water—by about 15% to 20% compared to the original recipe.
Conversely, because the bottom gets hotter than the sides, thick sauces (like barbecue sauce or cream soups) can scorch. If you are making chili, put the broth and vegetables at the bottom and layer thick tomato products on top. Do not stir. This prevents the “Burn” error that newer models sometimes trigger even in non-pressure modes.
Food Size And Placement
Cut your root vegetables smaller than usual. Carrots and potatoes take a long time to soften in an Instant Pot’s slow cook mode because they aren’t getting radiant heat from the sides. Cut potatoes into one-inch chunks rather than quarters. Place these hard vegetables on the very bottom of the stainless steel pot where the heat is most direct. Place your meat on top of the vegetables.
Common Pitfalls When You Use An Instant Pot As A Slow Cooker
Users frequently report disappointment after their first attempt. The meat is tough, or the beans are hard. These issues usually stem from the temperature curve. A dedicated slow cooker ramps up heat slowly and holds it. The Instant Pot cycles its heating element on and off to maintain the target temp, but the thin metal wall drops temperature quickly during the “off” cycle.
For safety, always ensure your food reaches a safe internal temperature. The USDA Food Safety and Inspection Service warns that food held between 40°F and 140°F allows bacteria to grow rapidly. Since the “Less” setting hovers dangerously close to this lower limit, avoid it for raw poultry or pork.
Beans Staying Hard
Dry beans are notorious for failing in this mode. They require sustained steady heat to break down. If the temperature dips too often, they remain chalky. If you must cook beans, soak them overnight first, or use the “More” (High) setting. Better yet, use the pressure cook function for beans—it does in 40 minutes what slow cooking does in 8 hours.
Thickening Sauces
Since evaporation is minimal, your stews won’t thicken naturally. You will likely need to add a cornstarch slurry at the end. Once the slow cook cycle is done, switch the pot to “Saute” mode. Stir in your thickener and let it bubble for a few minutes. This is one advantage the Instant Pot has—you can sear and thicken in the same vessel without dirtying a pan.

| Chicken Breasts | Normal (Medium) | Check 30 mins early to prevent drying |
Troubleshooting Your Results
If you open the lid and find the meal isn’t done, don’t panic. This is common when learning how to use an Instant Pot as a slow cooker effectively. Unlike pressure cooking, you can simply put the lid back on and add time. If the food is significantly undercooked, you can switch to “Pressure Cook” (Manual) for 5 to 10 minutes to finish the job quickly. This saves the meal without waiting another two hours.
If you find that your food has a metallic taste, it might be due to acidic ingredients reacting with the stainless steel over very long periods, though this is rare with high-quality steel. More likely, it is a lack of flavor concentration. Add a splash of acid (lemon juice or vinegar) or fresh herbs at the very end to brighten the flavor profile.
When To Stick To The Crock-Pot
While you can use an Instant Pot as a slow cooker, some dishes just work better in ceramic. If your recipe involves delicate custards, heavy cream bases that might curdle with bottom heat, or ultra-long 12-hour cook times, the thermal stability of a traditional heavy pot is superior. The thin metal of the Instant Pot is less forgiving for recipes that need extremely gentle, diffuse heat.
Also, consider the shape. The Instant Pot is tall and narrow. Large cuts of meat like a full brisket or a rack of ribs might not fit flat. In a wide oval Crock-Pot, they lay evenly in the liquid. In the IP, you might have to curl or stack them, which leads to uneven cooking. If you have to stack meat, ensure you rotate the pieces halfway through the cycle.
Converting Specific Dish Types
Different food categories require different strategies when making this switch. Here is how to handle the main groups.
Soups And Stews
These are the easiest to adapt. The liquid nature distributes the bottom heat well. Use the “Normal” setting. You can fill the pot higher than you would for pressure cooking, but leave an inch or two at the top to prevent boiling over if you switch to Saute mode later.
Roasts And Large Cuts
Sear the meat first. This is mandatory for flavor because you won’t get the browning that occurs in some high-end ceramic cookers. Use the “Saute” function to brown all sides of your chuck roast. Then, scrape the bottom of the pot to remove stuck bits (fond) before switching to slow cook mode. This adds flavor and prevents the sensors from thinking the pot is burning. For official guidance on operating modes, checking the Instant Pot user manual for your specific model is always smart, as buttons vary by series (Duo vs. Pro vs. Max).
Poultry
Chicken breasts dry out faster in an Instant Pot slow cook cycle than in a ceramic pot because the bottom heat is more intense. Use “Normal” rather than “More” for chicken, and rely on a meat thermometer. Thighs work better than breasts due to their higher fat content.
Making The Decision
If you have limited space, relying on the Instant Pot for slow cooking is a solid compromise. You gain the ability to pressure cook, sauté, and slow cook in one footprint. The trade-off is that you must be more active in the process. You have to check settings, buy a glass lid, and perhaps stir the pot once or twice. For most casual home cooks, this is a small price to pay for decluttering the kitchen.
Remember that the “Slow Cook” button is just a program, not magic. It controls a heating element that behaves differently than what you are used to. But once you master the “Normal” vs. “More” distinction and manage your liquid levels, you can turn out excellent meals. So, can I use an Instant Pot as a slow cooker? Yes, absolutely—as long as you respect the physics of the pot.
