Most Instant Pot owners stick with pressure cooking alone—but three accessory categories unlock entirely different cooking methods and dramatically expand what your pot can do. Steamer baskets let you cook vegetables and dumplings simultaneously with grains below. Trivet sets enable water bath cooking and multi-level meal prep. Silicone seals maintain the pressure integrity that makes everything work.
Before purchasing steamer baskets or trivets, verify they're compatible with your specific Instant Pot model size (3-quart, 6-quart, or 8-quart) since accessories vary significantly in dimensions and fit. Always check the replacement seal quality and material composition, as inferior silicone seals can degrade quickly and affect cooking performance, so investing in official or high-rated third-party alternatives will save money on frequent replacements.
The catch: these accessories serve different purposes, and many home cooks end up buying the wrong one—or all three without understanding why. This guide breaks down what each does, which brands and styles actually deliver, and which setup matches your cooking habits.
Steamer baskets feature food-grade stainless steel construction with strategically placed ventilation holes that allow steam to circulate without letting food fall through. Quality baskets include heat-resistant silicone handles and feet or raised edges that allow stacking with other accessories or combining with trivets for maximum cooking capacity. The best designs fit snugly inside specific Instant Pot models (6-quart vs. 8-quart make a real difference) and are fully dishwasher-safe.
Best for: Cooks who want to steam vegetables, fish, or dumplings while simultaneously cooking grains or proteins below. Also ideal if you meal prep and need to cook multiple components in one cycle.
Trivet sets use food-grade stainless steel with non-slip silicone feet to prevent sliding and protect your inner pot from scratches. The best sets include multiple heights or stackable configurations, allowing you to create different cooking zones and simultaneously steam vegetables on top while pressure cooking a sauce below. Compatibility varies—verify fit for your specific pot size (6-quart vs. 8-quart) to avoid jamming or poor seal.
Best for: Home cooks serious about multi-zone cooking who want to prepare two separate dishes in different-sized containers at once, or those doing extensive meal prep who need maximum versatility in one pot.
Single replacement seals made from 100% food-grade silicone rated to withstand temperatures up to 400°F. These are direct wear-and-tear replacements for the original seal that degrades over time from heat exposure and food residue buildup. Individual seals are the lowest-cost option but require knowing your exact model number, as different Instant Pot generations (3-quart, 6-quart, 8-quart) require specific dimensions.
Best for: Users whose existing Instant Pot seals show visible wear, leaking pressure, or cooking inconsistencies. Best if you already own an Instant Pot and just need a direct replacement without extra accessories.
Bundle packages that include replacement seals plus supporting accessories: anti-blocking racks, sealing ring storage containers, and cleaning tools. These kits provide better overall value and ensure you have all the supporting components needed to maintain peak performance. The bundled approach prevents you from discovering later that you also needed the anti-blocking rack or storage solution.
Best for: New Instant Pot owners or those upgrading their entire accessory ecosystem at once. Also ideal if you want a complete maintenance system in one purchase rather than buying pieces separately over time.
Some accessory sets allow you to layer or stack steamer baskets with trivets, creating multi-level cooking capacity. This hybrid approach requires baskets with proper feet or raised edges that fit trivets without binding, and careful verification that the combined height doesn't prevent lid closure. This is the most versatile setup but also the most complex to master.
Best for: Advanced home cooks who prepare multiple dishes regularly and want maximum flexibility in a single pot. Not recommended for beginners still learning pressure cooking fundamentals.
For most home cooks: Start with a stainless steel steamer basket if you cook vegetables and proteins regularly, or a trivet set if you meal prep multiple components. These solve the most common use cases without overwhelming you. For seal maintenance: Buy a comprehensive accessory kit once rather than individual seals later—the bundled anti-blocking racks and storage justify the higher upfront cost. For advanced users: A combination setup with stackable baskets and trivets unlocks the most versatility, but only if you've already mastered basic pressure cooking and understand your exact pot dimensions. The key mistake is buying all three types without a specific cooking problem in mind. Steamer baskets and trivets do fundamentally different things—baskets focus on steam circulation and stacking, trivets focus on protecting your cookware and creating separate cooking zones. Choose based on what you actually cook, not on what sounds impressive.
Not necessarily. Steamer baskets excel at vegetables and dumplings while cooking grains below. Trivets excel at protecting cookware and cooking two separate dishes at once. If you cook vegetables + grains often, choose the basket. If you meal prep multiple sauces or main dishes, choose the trivet. Some advanced cooks use both by stacking them, but that requires precise height management.
Signs include visible cracks or discoloration, pressure loss during cooking (lid won't seal or hisses steam continuously), or food residue that won't clean out. If your Instant Pot is more than 2-3 years old and used regularly, proactive replacement prevents mid-cook failures. Always use food-grade silicone rated to 400°F minimum.
No—6-quart and 8-quart pots have different internal dimensions. A 6-quart basket or trivet will be too small for an 8-quart pot and won't protect your cookware effectively. Always verify your exact model number (found on the bottom of the pot or in your manual) before purchasing.
Aluminum is food-safe under pressure, but flimsy aluminum baskets warp under heat and don't vent steam evenly. They also absorb food odors permanently. Food-grade stainless steel costs more upfront but outlasts aluminum by years and performs more consistently.
Yes, if both have proper feet or raised edges and your combined height doesn't exceed your pot's interior. This gives advanced cooks three cooking zones (pressure below, steam in middle, steam on top), but requires careful assembly and verification that the lid seals. Not recommended for beginners.
