No, you cannot use regular pots and pans directly inside an Instant Pot. The Instant Pot's inner pot is a specialized stainless steel vessel designed to work with the pressure cooking system, and using incompatible cookware can damage the appliance and create safety hazards.
Regular pots and pans are not designed to fit properly inside an Instant Pot's cooking chamber or to withstand its pressurized environment. The Instant Pot requires its specific stainless steel inner pot to function safely and effectively. While you can use certain oven-safe cookware as accessories within the pot using a trivet or steamer rack, they serve different purposes than direct cooking vessels. Always consult your Instant Pot manual before using any cookware inside the appliance.
Understanding why regular cookware doesn't work in an Instant Pot comes down to design and safety. The Instant Pot's inner pot is engineered specifically for pressure cooking—it has precise measurements, proper thickness, and specific material composition that allows it to seal correctly and distribute heat evenly under pressure. Regular pots and pans lack these specifications.
Sizing Issues: Standard kitchen pots typically won't fit inside an Instant Pot's chamber. The Instant Pot comes in various sizes (3-quart, 6-quart, 8-quart), and only cookware that fits within these dimensions without touching the heating element or lid can be used as accessories.
Pressure Seal Problems: The Instant Pot's inner pot has a specific shape and design that works with the appliance's sealing ring to maintain proper pressure. Using a different pot compromises the seal, which can lead to pressure loss, incomplete cooking, or dangerous pressure release.
Heat Distribution: The inner pot's thickness and material composition ensure even heat distribution during high-pressure cooking. Regular cookware may have thin spots that cause uneven cooking or burning, particularly since the Instant Pot uses direct heat on the bottom of the vessel.
What You CAN Use: While the inner pot itself must remain the original, you can use certain oven-safe glass bowls, silicone molds, or smaller pots placed on a trivet inside the Instant Pot for steaming or water bath cooking. These items don't replace the inner pot but rather sit inside it for specific cooking methods.
Instant Pot's official guidelines are clear: always use the included stainless steel inner pot for pressure cooking. Kitchen appliance experts emphasize that the inner pot's construction—typically 18/8 stainless steel—is critical for safety and performance. The pot must withstand repeated pressure cycles and maintain its integrity over hundreds of uses. Attempting to use regular cookware voids your warranty and can result in appliance damage, poor cooking results, or safety issues. Professional reviewers consistently note that the Instant Pot ecosystem is designed as a complete unit, where each component plays a vital role in the cooking process.
Rather than trying to use regular cookware, invest in proper Instant Pot accessories designed to work within the system. Instant Pot offers various compatible accessories including steamer racks, glass bowls, springform pans, and silicone egg molds that work perfectly inside the standard inner pot. These accessories expand your cooking possibilities without compromising safety or performance. You can find a wide selection of official and compatible accessories at Amazon's Instant Pot Accessories page, which includes options for different cooking methods and dietary needs.

Yes, you can use regular stainless steel pots and pans inside an Instant Pot as long as they fit and have a flat bottom that sits properly on the heating element. Common sizes are 6-inch and 8-inch round stainless steel bowls or pans that nest inside the inner pot. Make sure they don't touch the sides of the Instant Pot or prevent the lid from closing properly.
Most standard 6-quart Instant Pots can fit 6 to 8-inch round pans or bowls inside them, while 8-quart models can accommodate larger cookware. You should measure your cookware's diameter and height before purchasing to ensure it fits with at least an inch of clearance on all sides. Stackable stainless steel bowls designed for pressure cookers work best.
Non-stick pans can be used inside an Instant Pot as long as they're designed to handle high heat and steam, though they're less ideal than stainless steel. Aluminum pans are not recommended because aluminum can react with acidic foods and may discolor or damage the cookware. Stainless steel is the safest and most durable choice for use inside an Instant Pot.
You don't need special pans—any heat-safe pan with a flat bottom that fits inside will work for steaming on the trivet. Common options include stainless steel bowls, cake pans, or ramekins, though ceramic and glass cookware also work well. Just ensure your pan doesn't touch the heating element and leaves room for steam circulation around it.
