Can a Pyrex Bowl Go in an Air Fryer? Find Out Here

You’re standing in your kitchen, air fryer humming, and you’ve just prepped a delicious quinoa and roasted veggie bowl. It’s all ready in your favorite Pyrex bowl—the one you’ve used for years to store, reheat, and serve. But now, as you glance at the air fryer basket, a question pops into your mind: *Can I just pop this Pyrex bowl right in the air fryer?*

It’s a fair question—and one I’ve asked myself more than once. After all, Pyrex is known for being heat-resistant, right? We’ve all pulled a glass dish from the oven without a second thought. But air fryers are a different beast. They use rapid, high-heat convection, and the environment inside can be surprisingly intense. So, before you risk a shattered bowl (and a ruined dinner), let’s dive deep into whether your Pyrex bowl is air fryer-safe. We’ll explore the science, the risks, the best practices, and even some real-life examples to help you cook with confidence—without any kitchen disasters.

Understanding Pyrex: What Makes It Special?

The Science Behind Pyrex Glass

Pyrex is a household name, and for good reason. Originally developed in the early 1900s, traditional Pyrex was made from borosilicate glass, a material known for its exceptional resistance to thermal shock. That means it can go from the freezer to a hot oven without cracking—a dream for meal preppers and busy home cooks.

Borosilicate glass has a low coefficient of thermal expansion. In plain English? It doesn’t expand or contract much when heated or cooled rapidly. This property is what makes it safe for oven use. But here’s the catch: not all modern Pyrex is borosilicate.

Modern Pyrex: A Shift in Material

In the 1980s, many manufacturers—including Corning, which originally made Pyrex—switched to soda-lime glass for their consumer lines. This glass is cheaper to produce and still heat-resistant, but it’s more prone to thermal shock than borosilicate. So, if your Pyrex bowl was made after the 1980s (especially in the U.S.), it’s likely made from soda-lime glass.

This shift is critical because thermal shock is the biggest risk when using glass in an air fryer. The sudden blast of hot air—sometimes exceeding 400°F (205°C)—combined with the metal basket and rapid airflow, creates a high-stress environment for any glass container.

How to Tell What Kind of Pyrex You Have

Wondering if your bowl is borosilicate or soda-lime? Here’s a quick way to check:

• Check the bottom: Look for markings. Older Pyrex (pre-1980s) often says “Pyrex” in cursive with a “Made in USA” stamp. Some newer pieces may say “Tempered Glass” or “Oven Safe.”
• Look for the logo: If it says “Pyrex” with a modern font and no mention of borosilicate, it’s likely soda-lime.
• Check the weight: Borosilicate tends to be slightly heavier and more durable than soda-lime.
• Manufacturer info: Brands like Anchor Hocking (which now owns the Pyrex brand in the U.S.) use soda-lime glass. However, some international versions (e.g., Pyrex in Europe) still use borosilicate.

So, if you’re unsure, assume it’s soda-lime—and treat it with extra caution. Better safe than shattered!

How Air Fryers Work and Why That Matters for Glass

Air Fryer Mechanics: More Than Just a Tiny Oven

Air fryers aren’t just mini convection ovens—they’re high-speed heat blasters. Using a heating element and a powerful fan, they circulate hot air at speeds up to 2,000 RPM. This creates a crisp, golden exterior on foods (think: fries, chicken wings, even roasted veggies) without needing a deep fryer.

The temperature inside an air fryer can range from 175°F to 400°F (80°C to 205°C), and the air moves fast—often at 10–20 mph. This intense airflow is great for food, but it can create uneven heating in glass containers.

Why Glass Can Crack in Air Fryers

Glass doesn’t conduct heat evenly. When you place a cold Pyrex bowl into a 400°F air fryer, the outer surface heats up instantly, while the inside remains cooler. This temperature difference creates stress—called thermal stress—and if the stress is too great, the glass cracks or shatters.

Here’s what makes air fryers especially risky:

• Rapid preheating: Most air fryers heat up in 2–3 minutes, giving no time for the glass to warm gradually.
• Metal basket contact: The bowl may touch the hot metal basket, creating localized hot spots.
• Airflow patterns: Air hits one side of the bowl more than the other, causing uneven expansion.
• Sudden temperature drops: If you open the basket mid-cooking, cold air rushes in—another shock risk.

Real-Life Example: The “I Tried It” Story

A few years ago, my friend Sarah tried to cook a frittata in her Pyrex pie dish inside her air fryer. She preheated the air fryer to 375°F, placed the dish in, and set the timer. Five minutes later—*crack!* The dish split cleanly down the middle. No warning. No wobble. Just a clean break. She was devastated (and had to clean up tiny glass shards for weeks).

After some research, she realized her Pyrex was soda-lime glass, and she hadn’t preheated the dish. The lesson? Even oven-safe glass isn’t always air-fryer-safe—especially if you skip the pre-warming step.

Can You Use Pyrex in an Air Fryer? The Verdict

Yes… But With Major Caveats

So, can a Pyrex bowl go in an air fryer? The short answer: **sometimes, but not without precautions**. It depends on:

• The type of Pyrex (borosilicate vs. soda-lime)
• The size and shape of the bowl
• Whether you preheat the bowl
• The air fryer model and temperature settings
• The food being cooked (e.g., liquid vs. solid)

If you’re using a **borosilicate Pyrex bowl** and follow strict safety steps, you can use it—but even then, it’s not the safest choice. For soda-lime Pyrex, the risk is much higher, and I’d strongly advise against it unless you’re willing to accept the possibility of breakage.

When It Might Work (With Caution)

There are a few scenarios where using Pyrex in an air fryer is *less risky*:

• Low to medium temperatures (under 350°F / 175°C): Less thermal shock.
• Preheating the bowl: Place the empty bowl in the air fryer during preheating. This slowly warms the glass.
• Using a shallow, wide bowl: Thinner glass heats more evenly. Deep, narrow bowls are riskier.
• Cooking liquids or moist foods: The food helps regulate temperature and reduces hot spots.
• No sudden temperature changes: Don’t open the basket mid-cooking or place a hot bowl on a cold counter.

For example, you might safely reheat a bowl of soup or warm up a casserole in a shallow Pyrex dish at 325°F—if you preheat the bowl first and monitor closely.

When You Should Absolutely Avoid It

Here’s when you should never use Pyrex in an air fryer:

• Using high heat (above 375°F / 190°C)
• Using a deep or narrow bowl (e.g., a measuring cup or tall casserole dish)
• Placing a cold bowl into a preheated air fryer
• Cooking frozen or icy foods directly in the bowl (thermal shock risk)
• Using a bowl with cracks, chips, or scratches (weak spots can fail under stress)
• Using a bowl that doesn’t fit securely (wobbling = uneven heat)

Remember: Even if your Pyrex survives one cooking session, repeated thermal stress can weaken it over time. One day, it might just give out—with no warning.

Safer Alternatives to Pyrex in the Air Fryer

Air-Fryer-Safe Materials You Can Trust

Instead of risking your Pyrex, consider using materials specifically designed for high-heat, high-airflow environments. Here are the best alternatives:

• Silicone molds and baskets: Flexible, heat-resistant (up to 428°F / 220°C), and safe for air fryers. Great for muffins, egg bites, or even mini casseroles. Just make sure they’re food-grade silicone and don’t touch the heating element.

<

• Stainless steel bowls: Durable, non-reactive, and perfect for mixing and cooking. Just ensure they’re not too large (to allow airflow) and use oven mitts when handling.
• Cast iron skillets (mini sizes): Excellent for searing or baking. Preheat with the air fryer to avoid thermal shock.
• Ceramic baking dishes: Look for oven-safe, air-fryer-approved ceramic. Brands like Le Creuset make mini cocottes that fit in most air fryers.
• Air fryer-safe parchment paper or liners: Use these in a metal or silicone basket to protect food and make cleanup easy.

Top Picks for Air Fryer Bowls and Dishes

Here’s a quick comparison of popular air fryer-friendly containers:

Material	Max Temp	Best For	Pros	Cons
Silicone	428°F (220°C)	Muffins, egg bites, small casseroles	Non-stick, flexible, easy to clean	Can retain odors; avoid sharp utensils
Stainless Steel	500°F+ (260°C+)	Mixing, roasting, reheating	Durable, no leaching, oven-safe	Can get very hot; not non-stick
Cast Iron (mini)	500°F+ (260°C+)	Frittatas, seared meats, cornbread	Excellent heat retention, sears well	Heavy; requires seasoning
Ceramic	450°F (230°C)	Casseroles, baked eggs, desserts	Attractive, non-reactive, oven-safe	Can crack if dropped; check for air fryer safety

My personal favorite? A set of mini silicone muffin cups. I use them for air fryer egg bites, mini meatloafs, and even chocolate lava cakes. They’re cheap, reusable, and never crack!

Pro Tip: Use the Air Fryer Basket Itself

Often, the safest and most effective way to cook is to skip the bowl entirely and use the air fryer basket directly. Line it with parchment or a silicone liner, add your ingredients, and let the air do its magic. No extra dishes, no risk of breakage, and maximum crispiness.

For example, instead of cooking a quinoa bowl in a Pyrex dish, cook the quinoa separately, then mix it with roasted veggies and protein directly in the basket. Toss with sauce at the end—easy, fast, and safe.

Best Practices for Using Glass in High-Heat Appliances

General Rules for Glass in Air Fryers, Ovens, and Microwaves

Whether you’re using an air fryer, oven, or microwave, these rules apply to any glass container:

• Preheat the container: If using glass, place it in the appliance during preheating. This slowly warms the glass and reduces thermal shock.
• Avoid extreme temperature changes: Don’t take a hot bowl straight to cold water or a cold surface. Let it cool on a trivet or heat-safe surface.
• Check for damage: Inspect for chips, cracks, or scratches. Even small flaws can become failure points under heat.
• Use even heating: Don’t place glass directly under a broiler or in a hot spot (e.g., touching the heating element).
• Don’t use for deep frying: Glass isn’t designed for oil immersion or direct flame.
• Follow manufacturer guidelines: If the bowl says “not for stovetop or broiler,” respect that.

What to Do If Glass Breaks in Your Air Fryer

It happens. If your Pyrex cracks or shatters:

1. Unplug the air fryer immediately to prevent glass from melting onto the heating element.
2. Let it cool completely before handling.
3. Carefully remove large pieces with tongs or gloves.
4. Use damp paper towels or tape to pick up tiny shards.
5. Wipe down the basket and interior with a damp cloth and mild detergent.
6. Inspect the heating element and fan for glass fragments—don’t run the air fryer until it’s clean.

And yes, I’ve been there. After Sarah’s frittata fiasco, we spent an hour picking glass out of the basket. Never again!

Long-Term Care for Glass Cookware

Even if you don’t use it in the air fryer, treat your Pyrex with care:

• Wash with mild soap and avoid abrasive scrubbers.
• Don’t stack heavy items on top of glass bowls.
• Store with soft liners to prevent chipping.
• Retire any bowl that’s been through extreme heat cycles (e.g., oven to freezer).

Final Thoughts: Is It Worth the Risk?

So, can a Pyrex bowl go in an air fryer? Technically, yes—but only under very specific, cautious conditions. For most home cooks, the risk of breakage, cleanup, and potential injury just isn’t worth it.

Think of it this way: Your air fryer is a high-performance tool. It’s meant to deliver crispy, delicious results quickly. But it’s not designed to handle fragile glass in the same way a slow, even oven does. The intense airflow, rapid temperature changes, and metal contact create a perfect storm for thermal shock.

If you’re set on using a bowl, go for air fryer-safe silicone, stainless steel, or ceramic. They’re designed for this environment, safer, and often more functional. Plus, they’re easier to clean and more versatile.

And if you’re attached to your Pyrex? Use it for prep, storage, or serving—but keep it out of the air fryer basket. There’s no shame in playing it safe. After all, the goal is to enjoy your food, not spend an evening picking glass out of your kitchen.

At the end of the day, cooking should be fun, not stressful. So grab a silicone mold, line your basket with parchment, or just cook directly on the rack. Your meals will be just as delicious—and your Pyrex will stay intact for years to come.
