7 Common Instant Pot Mistakes (And How to Avoid Them)

The Instant Pot is not out to get you. It’s not judging your life choices. It’s not “randomly” flashing BURN just to humble you in front of your family. (Okay, it sometimes feels like that.) Most “Instant Pot disasters” come down to a handful of predictable pressure-cooker mistakeseasy fixes once you know what the machine actually needs to do its job: create steam, build pressure, and cook evenly.

This guide covers the most common Instant Pot mistakes home cooks makeplus exactly how to avoid themwith real-world examples so you can stop Googling “why is my Instant Pot screaming at me” and start enjoying dinner that tastes like you meant it.

A 30-Second Safety Pep Talk (Worth Reading)

Pressure cookers are safe when used correctly, but they’re still cooking under pressure. Never force the lid open, keep hands/face away from the steam vent during quick release, and use extra caution with starchy or foamy foods that can sputter. If a recipe says “natural release,” it’s not being dramaticit’s trying to keep your ceiling clean.

1) Forgetting to Seal (or Missing a Sealing Ring)

What it looks like: The pot never comes to pressure, steam pours out constantly, the timer doesn’t start counting down, and you start questioning your relationship with technology.

Why it happens

• The steam release valve is set to Venting instead of Sealing.
• The silicone sealing ring isn’t seated properlyor it’s not in the lid at all (yes, this happens to smart people).
• The lid isn’t fully closed or the float valve is stuck.

How to avoid it (the “3-point pre-flight check”)

1. Ring: Before you add food, run your finger around the sealing ring to make sure it’s seated evenly in the rack. No twists, no gaps.
2. Lid: Close the lid fully until it locks.
3. Valve: Confirm the steam release is set to Sealing for pressure cooking.

Example: You’re making shredded chicken tacos. You set it and walk away. Ten minutes later it’s hissing like an angry tea kettle. Nine times out of ten, the valve was left on Venting. Flip it to Sealing (carefully), and the pot will usually pressurize normallyassuming you haven’t lost too much liquid to steam.

2) Not Using Enough Thin Liquid (Steam Can’t Magically Appear)

What it looks like: The pot struggles to pressurize, cooking is uneven, or you get the dreaded BURN warningespecially with sauces, rice, or anything thick.

Why it happens

Pressure cooking requires thin, water-based liquid to boil and create steam. Thick mixtures (like tomato sauce, cream, or gravy) don’t produce steam efficiently and can overheat at the bottom before pressure builds.

How to avoid it

• Start with enough thin liquid: Water, broth, stock, winesomething pourable and not thickened.
• Respect your pot size: Smaller pots generally need less; larger pots need more. When in doubt, add a bit more thin liquid (you can always reduce after cooking using Sauté).
• Thicken after pressure cooking: Use cornstarch slurry, roux, cream, or cheese at the end on Sauté mode.

Example: You try to pressure cook a “one-pot” creamy pasta sauce with heavy cream as the base. The bottom overheats, and the pot throws a fit. Better approach: cook pasta (or chicken) with broth/water, then stir in cream and cheese afterward.

3) Skipping the Deglaze Step (Hello, Burn Notice)

What it looks like: You sauté onions or brown meat, add everything else, hit Pressure Cook… and the display flashes BURN like it’s mad you dared to try.

Why it happens

Those browned bits stuck to the bottom (aka “fond,” aka “flavor gold”) can trigger the burn sensor if they remain stuck when the pot starts heating under pressure. The pot wants a clean-ish bottom so heat transfers evenly through liquid.

How to avoid it (the foolproof deglaze)

1. After sautéing, hit Cancel to stop the direct heat.
2. Add a splash of thin liquid (broth/water/wine).
3. Scrape the bottom with a wooden spoon until nothing is stuck.
4. Only then add thicker ingredients (tomato paste, sauces, dairy) and proceed.

Example: Chili night. You brown beef, then add tomato paste and beans and stir like you’re conducting an orchestra. Burn notice. Fix: deglaze with broth first, then layer the thick stuff on top (more on layering in mistake #6).

4) Overfilling the Pot (Those Fill Lines Are Not Decorative)

What it looks like: Foam spews from the valve during quick release, the pot struggles to pressurize, or you end up with a clogged vent (best case: a mess; worst case: unsafe pressure behavior).

Why it happens

Under pressure, liquids boil vigorously and foods can expand. If the pot is too full, foam and particles can travel upward and block the pressure release pathway.

How to avoid it

• General rule: Fill to a maximum of about 2/3 for pressure cooking.
• Expanding/foamy foods: Stay around 1/2 full for rice, beans, oats, pasta, split peas, and anything that bubbles up like it’s auditioning for a bubble bath commercial.
• Batch smarter: If you need more food, cook in two rounds or use pot-in-pot cooking with a smaller container inside the liner (great for rice, cheesecake, and custards).

Example: You decide to “meal prep” by making a huge pot of beans, filled nearly to the max line. Beans expand, foam rises, and suddenly you’re cleaning bean confetti off your vent. Use the half-full guideline for beansyour future self will thank you.

5) Using the Wrong Pressure Release Method (Quick vs. Natural)

What it looks like: Foamy sputtering from the valve, tough meat, overcooked vegetables, or soups that erupt like Old Faithful (but less scenic).

Why it happens

Pressure release controls how aggressively the boil calms down. Quick Release (QR) dumps steam fast; Natural Release (NR) lets pressure drop gradually. Some foods need that gentle cooldown to prevent liquid from violently boiling up through the vent.

How to avoid it (quick cheat sheet)

• Use Natural Release for: soups, stews, beans, grains, oatmeal, and starchy/foamy foods. Also for big cuts of meat (it helps keep them tender).
• Use Quick Release for: quick-cooking vegetables, seafood, and anything you don’t want to keep cooking from carryover heat.
• Compromise move: Try a “10-minute natural release,” then quick release the restcommon in many recipes.
• Mess-control tip: If you must quick release something a little risky, vent in short bursts (or use a towel held safely away from the vent to redirect steamnever cover the valve fully).

Example: You cook chicken noodle soup and quick release immediately. The broth spits, the vent gets foamy, and you learn a new cleaning technique. Next time: let it naturally release at least 10–15 minutes, then finish with quick release if needed.

6) Stirring in Thick Ingredients Too Early (Tomatoes, Dairy, and Flour Love to Scorch)

What it looks like: Burn notice, scorched sauce on the bottom, or uneven cookingespecially in tomato-heavy recipes (chili, marinara, curry) or anything thickened with flour/cornstarch.

Why it happens

Thick ingredients can sink, stick, and overheat before the pot fully pressurizesparticularly if they’re stirred directly onto the bottom. Tomato paste, thick tomato sauce, cream, and flour-thickened bases are frequent offenders.

How to avoid it (layering is your superpower)

1. Liquid first: Add broth/water to the bottom.
2. Solids next: Add meat/veg/pasta (as the recipe allows).
3. Thick stuff last: Spoon tomato products or thick sauces on top and do not stir before pressure cooking.
4. Thicken at the end: Stir in dairy, cheese, and slurries after cooking (use Sauté to finish).

Example: Marinara in the Instant Pot. If you pour in tomato sauce, stir, and pressure cook, the thick base can scorch. Better: water/broth first, then tomatoes on top, no stirring. Once cooking is done, stir and simmer on Sauté if you want it thicker.

Bonus trick: If you love thick sauces, consider pot-in-potplace sauce ingredients in a smaller oven-safe bowl on a trivet with water underneath. It’s like a gentle steam bath for your dinner (and way less drama).

7) Neglecting Cleaning and Maintenance (A Dirty Pot Can Cook Like a Grudge)

What it looks like: Sealing issues, weird smells, the float valve sticking, repeated burn warnings, or steam leaking where it shouldn’t.

Why it happens

The Instant Pot depends on a few small partssealing ring, float valve, anti-block shield, steam release componentsworking smoothly. Food residue or worn silicone can mess with pressure, heat, and reliability.

How to avoid it (low effort, high reward)

• Clean the lid parts regularly: Remove and wash the sealing ring, anti-block shield, and any removable valve pieces per your model instructions.
• Check the float valve: Make sure it moves freely and isn’t sticky from starch or sugar.
• Own two sealing rings: One for savory foods (garlic, curry, chili) and one for sweet/neutral (cheesecake, rice pudding). Silicone holds odors.
• Replace worn rings: If the ring is stretched, cracked, or permanently smells like last month’s garlic festival, it’s time.

Example: Your cheesecake tastes vaguely like cumin. Congratulations: your sealing ring is a spice sponge. Swap to a “dessert ring” and store rings separately.

A Quick Instant Pot Troubleshooting Checklist

• Not sealing? Check valve = Sealing, ring seated, lid locked, float valve clean.
• Burn notice? Add thin liquid, deglaze bottom, don’t stir thick sauces into the base, layer tomatoes on top.
• Foamy sputter on release? Use natural release for starchy/foamy foods; don’t overfill.
• Food over/undercooked? Remember pressure build time + release time; adjust next round.

Conclusion: A Calm Instant Pot Is a Consistent Instant Pot

Most Instant Pot problems aren’t mysteriesthey’re patterns. Seal it. Add enough thin liquid. Deglaze like you mean it. Don’t overfill. Use the right release. Treat thick sauces with respect (layer, don’t stir). Keep the parts clean. Do those seven things, and your Instant Pot becomes what it promised to be: fast, convenient, and oddly satisfyinglike a kitchen robot that actually follows through.

Bonus: Real-World “Instant Pot Moments” (What These Mistakes Look Like in Real Kitchens)

Let’s make this painfully relatable. Because the fastest way to learn Instant Pot tips is to recognize the exact moment a mistake is happeningpreferably before the pot starts beeping like it’s calling security.

Moment #1: The “Why won’t it start?” stare-down. You’ve loaded the pot, hit Pressure Cook, and nothing happens… except steam escaping from the top like a tiny locomotive. In your head, you’re already drafting an apology letter to dinner. This is almost always the vent set to Venting or a sealing ring that isn’t seated. The fix is boring: pause, check the ring, set to Sealing, restart. The lesson: build a pre-flight routine. You can forget your phone charger; you can’t forget the sealing ring.

Moment #2: The “BURN” message betrayal. You sautéed onions and browned meat, and your kitchen smells incredible. Then you pressure cook andbamburn warning. It feels unfair because you were doing the “chef thing.” But the Instant Pot doesn’t care about your vibe; it cares about what’s stuck to the bottom. In real life, the best habit is to deglaze immediately after sautéing, before you add anything thick. If you can run your spoon across the bottom and feel rough spots, your pot can feel them too (and it will complain).

Moment #3: The “tomato trap” in chili or pasta sauce. Someone teaches you a recipe that says “dump everything in and stir,” and you do… including tomato paste. Under pressure, that thick tomato base can scorch before steam fully builds. The trick you’ll see experienced cooks use is layering: liquid on bottom, then solids, then tomato products on topno stirring until after cooking. It looks weird the first time. Then it works, and you become a layering evangelist.

Moment #4: The “steam volcano” quick release. You’re hungry, so you quick release a pot of soup or oatmeal. Steam roars, liquid sputters, and suddenly your vent is wearing dinner. This is the moment you learn that release method is part of the recipe, not a suggestion. Natural release feels slow, but it’s often faster than cleaning splatter out of valve parts. Real-kitchen compromise: let it naturally release 10–15 minutes, then quick release the rest.

Moment #5: The “why does dessert taste like curry?” surprise. You make a cheesecake that tastes… savory. Not in a charming “salted caramel” way. In a “did I accidentally add cumin?” way. Odds are your sealing ring has absorbed odors. People who use the Instant Pot weekly often keep two ringsone for savory, one for sweet. It’s not extra. It’s peace.

Moment #6: The “I thought it would take 8 minutes” misunderstanding. Many recipes list an 8-minute pressure cook time and forget to mention the 10–15 minutes to come to pressure and another chunk of time to release. Real kitchen planning means building in that extra timeespecially for big batches. Once you start thinking in “total time,” the Instant Pot becomes predictable instead of chaotic-good.

Moment #7: The “this thing is broken” panic… that isn’t. The float valve sticks, the lid feels locked, and you’re tempted to force it. Don’t. In real kitchens, the best move is to wait, verify pressure is released, and keep the lid parts clean so valves move freely. A clean, well-maintained pot behaves like an appliance. A neglected one behaves like a moody roommate.

If you’ve lived any of these moments, congratulationsyou’re officially an Instant Pot cook. The win isn’t never making mistakes. The win is recognizing them fast, fixing them safely, and getting dinner back on track without ordering “emergency pizza.”
