Why You Might Be Wondering If Glass Bowls Can Go in an Air Fryer

Let’s be honest: air fryers have changed the way we cook. From crispy fries to juicy chicken wings, they’ve become the go-to appliance for quick, healthy, and delicious meals. But as we dive deeper into the world of air frying, questions start popping up—like, “Can glass bowls go in air fryer safely?”

It’s a fair question, especially if you’re like me and hate washing extra dishes. Why dirty a baking tray when you could just pop a glass bowl straight into the basket? After all, glass is non-toxic, microwave-safe, and doesn’t absorb odors. But here’s the catch: air fryers work differently than microwaves. They use intense, direct heat and rapid air circulation, which can be brutal on certain materials.

How Air Fryers Work and Why It Matters for Glass

The Science Behind Air Frying

Air fryers don’t actually “fry” food. Instead, they circulate hot air—usually between 300°F and 400°F (149°C to 205°C)—at high speed around food to create a crispy, golden exterior. Think of it like a mini convection oven with a powerful fan. The heat comes from a heating element at the top, and the fan pushes that heat down and around the food.

This process creates two major challenges for materials like glass: rapid temperature changes and direct exposure to intense heat. Unlike an oven, where heat builds gradually and evenly, air fryers blast heat from one direction, often causing uneven heating in containers.

Why Glass Reacts Poorly to Sudden Heat

Glass, especially regular glass (like Pyrex or Anchor Hocking), is designed to handle steady, even heat—like in an oven. But when you place a cold glass bowl into a hot air fryer, or vice versa, the sudden shift in temperature can cause thermal shock. This means the glass expands or contracts too quickly, leading to cracks or even shattering.

Imagine holding an ice cube in your hand. It melts slowly. But if you drop that ice cube into a hot frying pan, it explodes. That’s kind of what happens with glass in an air fryer. The outside of the bowl heats up fast, while the inside stays cool, creating stress points that can lead to breakage.

I learned this the hard way once. I put a chilled glass bowl straight into a preheated air fryer to reheat some soup. Five minutes later—crack!—I had glass shards and cold soup all over the basket. Not fun.

Types of Glass and Their Air Fryer Compatibility

Tempered Glass vs. Regular Glass

Not all glass is created equal. The key difference is whether it’s tempered glass or regular (annealed) glass.

• Tempered glass is heat-treated to be 4-5 times stronger than regular glass. It’s designed to handle temperature changes better and is often labeled “oven-safe” or “heat-resistant.” Brands like Pyrex (in its newer lines) and Anchor Hocking use tempered glass.
• Regular glass is more fragile and prone to cracking under thermal stress. Older Pyrex bowls (pre-1998) were made from borosilicate glass, which is more heat-resistant, but newer versions use tempered soda-lime glass, which is safer but still has limits.

So, can glass bowls go in air fryer? Maybe—but only if they’re made of tempered glass and meet specific safety standards.

Oven-Safe Glass: A Closer Look

Many glass bowls are labeled “oven-safe,” but that doesn’t automatically mean “air fryer-safe.” Here’s why:

• Ovens heat gradually and evenly from all sides.
• Air fryers heat quickly and unevenly, with hot air blasting from the top.
• Oven-safe glass can usually handle up to 450°F (232°C), but the rate of heating matters more in air fryers.

For example, a tempered glass casserole dish might survive 30 minutes in a 400°F oven, but if you place it in a preheated air fryer at 400°F, the rapid heat exposure could cause it to crack within minutes.

Tip: Check the bottom of your glass bowl. If it says “Oven Safe,” “Tempered,” or “Borosilicate,” it’s more likely to survive air fryer conditions. But always avoid sudden temperature changes.

Borosilicate Glass: The Gold Standard

Borosilicate glass (like old Pyrex or brands like Duralex) contains boron trioxide, which makes it highly resistant to thermal shock. It can handle temperatures from -40°F to 572°F (-40°C to 300°C) and is used in lab equipment and high-end cookware.

While it’s the safest glass for air fryers, it’s not foolproof. Rapid heating from one direction (like in an air fryer) can still stress the material. But if you must use glass, borosilicate is your best bet.

When It’s Safe to Use Glass Bowls in an Air Fryer

Preheating the Air Fryer with the Bowl

One of the safest ways to use a glass bowl in an air fryer is to preheat both the appliance and the bowl together. Here’s how:

1. Place the empty glass bowl into the air fryer basket.
2. Set the air fryer to the desired temperature (e.g., 350°F).
3. Let it preheat for 3–5 minutes.
4. Carefully add your food and cook as usual.

This method reduces thermal shock by warming the glass gradually. I’ve used this trick to bake small portions of lasagna or reheat soups without issues—as long as the bowl was tempered and room temperature.

Cooking Low-Temperature, Moist Dishes

Glass bowls work best in air fryers for foods that:

• Cook below 375°F (190°C)
• Contain plenty of moisture (like stews, casseroles, or oatmeal)
• Don’t require direct browning (since the bowl blocks airflow)

For example, I’ve successfully made individual chocolate lava cakes in a tempered glass ramekin. The cake stayed moist, and the bowl didn’t crack because I preheated it and kept the temperature at 325°F.

But I wouldn’t try to make crispy chicken tenders in a glass bowl—the lack of airflow and high heat needed would likely cause breakage.

Using Glass for Reheating, Not Cooking

One of the safest uses for glass bowls in air fryers is reheating leftovers. Since the food is already cooked, you don’t need extreme heat. Just:

• Place the glass bowl with food in the cold air fryer.
• Set to 300–325°F.
• Heat for 5–10 minutes, stirring halfway.

This slow, low-heat approach minimizes thermal stress. I’ve reheated chili, curry, and even rice pudding this way with zero issues.

When You Should Avoid Glass Bowls in an Air Fryer

High-Heat Cooking (Above 375°F)

If your recipe calls for temperatures above 375°F (190°C), skip the glass. At these temps:

• The air fryer’s heating element is working at full power.
• Heat is concentrated on the top of the bowl.
• Even tempered glass can’t handle the stress.

I once tried to make garlic knots in a glass bowl at 400°F. The outside of the bowl turned scorching hot, while the inside stayed cool. After 8 minutes, it cracked with a loud pop. Lesson learned: use metal or silicone for high-heat recipes.

Frozen or Cold Glass Bowls

Never put a cold glass bowl into a preheated air fryer. The temperature difference is too extreme. Always:

• Let the bowl sit at room temperature for 10–15 minutes before use.
• Or, preheat the bowl with the air fryer (as mentioned earlier).

One time, I pulled a glass bowl straight from the fridge to reheat soup. The air fryer was already hot at 350°F. The result? A cracked bowl and soup all over the heating element. Not only was it dangerous, but cleaning the basket was a nightmare.

Deep or Narrow Bowls

Air fryers need airflow to work. Deep, narrow glass bowls block circulation, leading to:

• Uneven cooking
• Hot spots that stress the glass
• Longer cooking times

Stick to shallow, wide bowls that allow air to flow around the food. For example, a 1-quart Pyrex casserole dish works better than a deep cereal bowl.

Safer Alternatives to Glass Bowls in Air Fryers

Silicone Containers: The Air Fryer Hero

Silicone is flexible, heat-resistant (up to 425–500°F), and immune to thermal shock. It’s the best material for air fryer cooking. Look for:

• BPA-free, food-grade silicone
• Reinforced sides (won’t collapse under heat)
• Oven-safe labels

I use silicone muffin cups to make individual quiches and silicone loaf pans for banana bread. They’re easy to clean, don’t scratch the basket, and never crack.

Metal Pans and Ramekins

Stainless steel and aluminum are excellent choices. They conduct heat evenly and withstand high temperatures. Just make sure:

• The metal doesn’t touch the heating element (keep it in the basket).
• Use oven-safe metal (not aluminum foil trays, which can melt).

I love using a small stainless steel bowl to make “air fryer mug cakes” or to crisp up tater tots. The food browns perfectly, and cleanup is a breeze.

Oven-Safe Ceramic Dishes

Ceramic (like CorningWare or stoneware) is another good option. It’s:

• Heat-resistant (up to 500°F)
• Non-reactive (won’t leach chemicals)
• Better at handling gradual temperature changes

But like glass, ceramic can crack if exposed to sudden heat. Always preheat it with the air fryer or start from room temperature.

Final Thoughts: Can Glass Bowls Go in Air Fryer Safely?

So, can glass bowls go in air fryer safely? The short answer is: sometimes, but with strict rules.

If your glass bowl is:

• Made of tempered or borosilicate glass
• At room temperature
• Used at temperatures below 375°F
• Preheated with the air fryer
• Shallow and wide (to allow airflow)

…then yes, you can use it. I’ve done it many times for reheating soups, baking small desserts, or making individual casseroles.

But if you’re cooking at high heat, using a cold bowl, or need crispy results, choose silicone, metal, or ceramic instead. They’re safer, more durable, and actually improve cooking performance.

Remember: air fryers are powerful tools, but they’re not magic. Using the right cookware isn’t just about safety—it’s about getting the best results. So next time you’re tempted to toss a glass bowl in the basket, ask yourself: “Is this worth the risk?” If there’s even a small chance of breakage, it’s not.

Stick to the guidelines, use common sense, and your air fryer will keep serving up delicious meals—safely and efficiently. And hey, if you’re ever unsure, just grab that silicone muffin cup. It’s cheap, reliable, and never lets you down.
