Air fryers have become one of the most-used kitchen appliances in America thanks to their fast cooking times, crispy results, and healthier approach to comfort food. But experts warn that not every food belongs inside an air fryer — and one popular movie-night snack could actually create a dangerous fire risk.

Can You Put Popcorn in an Air Fryer?

The short answer: experts say you shouldn’t.

While social media is full of “air fryer hacks,” popcorn remains one of the biggest foods to avoid cooking in an air fryer. Most air fryers simply don’t reach the roughly 400–460°F needed to reliably pop a kernel, so cooks are often left with a mix of burnt shells and hard, unpopped kernels. Kitchen appliance researchers at consumer group Which? have pointed to the same issue, noting that most air fryer models can’t get hot enough for proper popping.

Beyond the disappointing results, popcorn poses a real safety concern. Because kernels are lightweight, the rapid air circulation inside an air fryer can send them flying up toward the heating element, where they can scorch, smoke, or get lodged — creating a fire risk that lingers even into your next cooking session if the stuck piece isn’t noticed and removed.

So while the idea may sound convenient, attempting to make popcorn in an air fryer could damage your appliance and put your kitchen at risk. Stick with the microwave, stovetop, or a dedicated popcorn popper instead.

Why Popcorn Is One of the Top Things You Should Never Put in an Air Fryer

Unlike microwaves or stovetop methods, air fryers circulate extremely hot air around lightweight foods. Popcorn kernels can shift unpredictably during cooking, and home cooks who’ve tried it online consistently report the same handful of problems:

• Burnt popcorn and bitter, smoky flavor
• Visible smoke coming from the vents
• Loud popping and kernels bouncing around the basket
• Unpopped kernels stuck near the heating element
• Uneven cooking and wasted food

Even workarounds involving foil, lower temperatures, or shaking the basket rarely produce consistent results — and none of them eliminate the fire risk from stray kernels near the heating coil.

Other Foods You Should Never Cook in an Air Fryer

Beyond popcorn, appliance experts and air fryer chefs have flagged several other foods that tend to cause smoke, mess, or safety issues:

❌ Uncooked Pasta & Grains

Air fryers don’t use water, so pasta, rice, and other grains won’t cook properly — you’ll end up with something closer to crunchy than tender.

❌ Bacon & Other Fatty, Greasy Foods

Bacon renders a large amount of fat quickly. That hot grease can spatter around the basket and pool at the bottom, producing heavy smoke and a stubborn mess to clean up.

❌ Cheesy or Melty Foods

Sliced cheese, cheesy toast, and similar foods can drip through the basket into the heating element, where they burn, smoke, and are difficult to scrape off.

❌ Large Bone-In Meats

Thick cuts like whole chickens or bone-in steaks may not cook evenly all the way through, raising food-safety concerns if the center doesn’t reach a safe internal temperature.

❌ Leafy Greens & Lightweight Foods

Kale, spinach, single tortillas, and other featherweight foods can fly around inside the basket and get caught in the heating element instead of cooking properly.

❌ Wet-Battered Foods

Wet batters — think beer batter or tempura — are designed to set quickly in hot oil. Without that oil bath, they don’t crisp up and instead turn into a soggy, sticky mess.

A General Safety Rule Worth Following

Fire safety officials who’ve responded to air fryer-related fires generally recommend keeping food at least two inches below the heating element, avoiding overcrowding the basket (which restricts airflow and can cause overheating), and only using appliances that carry a recognized safety certification. Never leave an air fryer running unattended, and always check that nothing greasy or lightweight has drifted up toward the coil before starting your next batch.

The Best Alternatives for Cooking Popcorn

Since air fryers aren’t built for popcorn, here are better ways to make it:

• 🎬 Microwave: Quick and foolproof — just follow the bag instructions.
• 🍳 Stovetop: Use a little oil and a covered pan for perfect homemade popcorn.
• 🍿 Air Popper: The easiest oil-free option!

Final Thoughts: Know What Not to Cook in an Air Fryer

While air fryers are an amazing kitchen tool, they can’t cook everything. Knowing the foods and habits to avoid — from popcorn and bacon to overcrowded baskets — will help you sidestep fire hazards, messy clean-ups, and disappointing meals.

So next time you’re experimenting with your air fryer, make sure your food is actually air-fryer friendly — your kitchen (and your taste buds) will thank you!
