Cooking with an Instant Pot has revolutionized how we prepare meals, offering convenience and speed. However, there are certain foods not to cook in an Instant Pot due to issues like texture loss, overcooking, or safety hazards. Knowing which foods to avoid will help you get the best results from this multi-functional appliance while preventing common cooking mistakes.
Why Some Foods Don’t Work in an Instant Pot
The Instant Pot works wonders for tough cuts of meat, grains, beans, and other hearty dishes. It uses pressure cooking technology to dramatically reduce cooking times, but this high-pressure environment is not suitable for everything. Certain foods require dry heat, precise temperature control, or delicate handling that the Instant Pot simply cannot provide. Avoid These Instant Pot Mistakes offers insight into common errors made when cooking with an Instant Pot, many of which stem from misunderstanding which foods can and cannot be cooked under pressure(
).
For instance, the moist, sealed environment of the Instant Pot is fantastic for making stews or steaming vegetables but is less suited for foods that need to retain crispiness or have a delicate texture. Foods that foam or expand significantly, such as pasta or certain legumes, can clog the pressure valve, leading to safety concerns and improperly cooked dishes(
).
Foods You Should Never Cook in an Instant Pot
1. Fried Foods
The Instant Pot may have many functions, but it cannot replicate the crispy exterior that frying requires. Fried foods like French fries or fried chicken need a dry, high-heat environment to get that perfect golden crust, something that the steam-filled environment inside the Instant Pot just cannot achieve.
- Why it doesn’t work: The Instant Pot’s environment produces moist heat, which leaves fried foods soggy and limp instead of crispy.
- Alternative: Use an air fryer or deep fryer to get the perfect crispiness on fried foods. Even though some Instant Pots come with an air fryer lid, it still doesn’t fully replicate the effects of deep frying(

).
2. Steak
If you’re a fan of a juicy, medium-rare steak, the Instant Pot is not the right tool. Cooking steak in an Instant Pot often results in overcooked, rubbery meat due to the high-pressure environment. A good steak needs to be seared at high heat to develop a flavorful crust, and cooking it under pressure robs it of this essential step.
- Why it doesn’t work: Pressure cooking doesn’t allow for precise temperature control or the creation of a crispy crust, which is essential for a good steak.
- Alternative: Sear steak in a cast-iron skillet or grill to achieve a caramelized exterior while keeping the inside tender and juicy(
)(
).
3. Dairy Products
While many recipes call for dairy products like milk, cheese, or cream, these ingredients are not well-suited to the high temperatures of an Instant Pot. Dairy tends to curdle when exposed to intense heat, separating into clumps and leaving your dish with a grainy texture.
- Why it doesn’t work: Dairy products can separate and curdle under high heat and pressure, ruining the texture of your dish.
- Solution: Add dairy products at the end of the cooking process, after releasing the pressure. For instance, stir in cream or cheese after the main ingredients have cooked(
)(
).
4. Pasta
Cooking pasta in an Instant Pot can be tricky. While it’s possible to make some pasta dishes, the pressurized environment often results in overcooked, gummy noodles. Additionally, pasta water tends to foam during pressure cooking, which can block the steam release valve and create a safety hazard.
- Why it doesn’t work: The pressure can cause pasta to overcook quickly, making it mushy and unappetizing.
- Alternative: Cook pasta on the stovetop to ensure it cooks evenly and maintains the desired texture. For dishes like mac and cheese, cook the pasta separately and stir it into your sauce(
).
5. Seafood
Delicate seafood like shrimp, scallops, and squid are best cooked quickly and at low temperatures to avoid becoming rubbery or overcooked. The high-pressure environment of an Instant Pot is too aggressive for these tender proteins.
- Why it doesn’t work: Seafood requires delicate cooking to prevent it from becoming tough, and the high-pressure setting can easily overcook it.
- Alternative: Sauté or grill seafood over medium heat to maintain its delicate texture. Use the Instant Pot for heartier proteins like fish in soups or stews(
).
6. Bread and Pastries
Baking bread or pastries in an Instant Pot is possible, but the results are often disappointing. The moist environment inside the cooker makes it difficult for dough to rise properly or for a crisp crust to form, leaving you with dense, underbaked results.
- Why it doesn’t work: Bread and pastries require dry heat to rise and form a crispy crust, which the Instant Pot’s moist cooking environment cannot provide.
- Alternative: Use a conventional oven or bread machine for baking bread, and reserve your Instant Pot for tasks better suited to its capabilities(
).
7. Stir-Fries
The Instant Pot has a sauté function, but it doesn’t provide the high, dry heat needed for stir-frying. Stir-fried dishes require quick cooking at very high temperatures to maintain the crunch of vegetables and to caramelize proteins. Attempting to stir-fry in an Instant Pot often leads to soggy, overcooked vegetables.
- Why it doesn’t work: The heat generated by the sauté function is too low to properly stir-fry, leading to uneven cooking and mushy vegetables.
- Alternative: Use a wok or a cast-iron skillet to achieve the high heat needed for stir-frying(
).
Foods to Approach with Caution in the Instant Pot
1. Foods that Foam: Oatmeal, Rice, and Lentils
Certain foods like oatmeal, rice, and lentils tend to foam during cooking. This foam can rise and block the steam release valve, which creates a safety risk. These foods also expand as they cook, which can lead to overfilling and undercooked portions.
- Why it’s tricky: Foods that foam can block the pressure release valve, leading to potential clogs and unsafe pressure buildup.
- Solution: Cook these foods in smaller portions, use plenty of water, and follow the recipe’s guidelines for liquid ratios(
).
2. Delicate Vegetables
Vegetables like asparagus, spinach, and zucchini are highly sensitive to overcooking. While the Instant Pot is excellent for starchy vegetables like potatoes and squash, these delicate greens can turn mushy and lose their nutritional value when cooked under pressure.
- Why it doesn’t work: Delicate vegetables overcook quickly and become mushy in the high-pressure environment.
- Solution: Use the steam function for 1-2 minutes or add delicate vegetables at the end of the cooking process to avoid overcooking(
).
3. Crispy Bacon or Sausage
Crispy bacon or sausage requires high, dry heat for the fat to render and create a crunchy texture. The Instant Pot’s moist environment will prevent these meats from crisping up properly, leaving you with soggy results.
- Why it doesn’t work: The Instant Pot lacks the ability to reach the necessary temperatures for crisping meats.
- Alternative: Fry or bake bacon and sausage separately, then add them to your Instant Pot recipes for flavor(
).
FAQs: Common Questions About Instant Pot Cooking
Can I Cook Dairy in an Instant Pot?
While it is possible to make some dairy-based dishes like yogurt in the Instant Pot, cooking with dairy directly inside under pressure can lead to curdling. Dairy products like milk, cream, and cheese should be added after the pressure cooking is complete.
- Best Practice: Stir dairy ingredients into the dish after releasing the pressure to avoid separation and curdling(
).
Why Shouldn’t I Cook Steak in an Instant Pot?
Steak requires high heat to develop a flavorful sear, which the Instant Pot’s pressure cooking mode cannot provide. Cooking steak in an Instant Pot will result in a mushy texture with no sear.
- Best Practice: Use the Instant Pot for braised dishes like pot roast or stews, and cook steak using a grill or skillet(
).
Is It Safe to Cook Pasta in an Instant Pot?
Cooking pasta in an Instant Pot is possible, but it comes with some challenges. If the pasta is cooked too long, it can quickly become mushy and overcooked, and if the liquid ratios aren’t correct, it can result in sticky, starchy water. Moreover, the starchy water can foam up and block the pressure valve, creating a safety concern.
- Best Practice: Cook pasta separately on the stovetop for better control of texture and doneness. If you decide to cook it in the Instant Pot, use just enough water and follow a strict cooking time to avoid a gummy mess. For dishes like mac and cheese, it’s recommended to cook the pasta first and then incorporate it with the sauce(
)(
).
Can I Cook Delicate Vegetables in an Instant Pot?
Delicate vegetables, such as asparagus, spinach, zucchini, or leafy greens, do not fare well in the Instant Pot. The intense pressure and heat can cause them to overcook rapidly, resulting in mushy textures and a significant loss of nutrients.
- Best Practice: Use the steam function for only a minute or two to maintain their crisp texture. Alternatively, add delicate vegetables at the end of the cooking process, once the pressure has been released, to preserve their color, nutrients, and texture(
).
Alternative Cooking Methods for Problematic Foods
Not all foods are ideal for the Instant Pot, but that doesn’t mean you can’t cook them well using other methods. For the foods listed above, here are some alternative cooking methods that will yield better results:
1. Use an Oven or Air Fryer for Crispiness
Foods that require a crispy texture—such as fried chicken, bacon, or breaded dishes—should be cooked in a dry-heat environment like an oven or air fryer. These appliances can reach the higher temperatures needed to develop the desired golden-brown crust, something the moist heat of the Instant Pot cannot achieve.
- Best Practice: Try using an air fryer for crispy foods like fried chicken, French fries, or even crisping up bacon(
).
2. Use a Cast-Iron Skillet for High-Heat Searing
For foods like steak, which require a sear or caramelization, using a cast-iron skillet or grill is the best option. These methods allow you to get a perfectly cooked steak with a rich, crispy crust while keeping the inside juicy and tender.
- Best Practice: Heat a cast-iron skillet over high heat, add a bit of oil, and sear your steak for 2-3 minutes on each side before finishing it in the oven or continuing to cook on the stovetop(
).
3. Cook Delicate Vegetables on the Stovetop
For vegetables that are highly sensitive to heat, such as zucchini, spinach, and broccoli, it’s best to cook them briefly on the stovetop or use the steaming function outside of pressure cooking. This allows you to maintain their texture and nutritional value.
- Best Practice: Use a steamer basket for vegetables in the Instant Pot, but set it to “steam” for no more than a minute or two, using a quick release to avoid overcooking(
).
