Can a Pyrex Dish Go in an Air Fryer Find Out Now

Yes, a Pyrex dish can go in an air fryer, but only if it’s labeled oven-safe and you avoid sudden temperature changes to prevent cracking. Always preheat the air fryer gradually and place the dish in a cold basket to ensure safe, even heating—never add cold Pyrex directly to a hot air fryer.

Key Takeaways

• Pyrex is air fryer-safe: It withstands high heat if handled properly.
• Preheat Pyrex first: Avoid sudden temperature changes to prevent cracking.
• Check for damage: Cracks or chips make Pyrex unsafe for air frying.
• Use oven mitts: Pyrex gets extremely hot—always handle with care.
• Follow weight limits: Don’t overload Pyrex to avoid breakage risks.
• Cool gradually: Let Pyrex cool before washing to prevent thermal shock.

Can a Pyrex Dish Go in an Air Fryer? Find Out Now

Let’s be honest — the air fryer is the kitchen superhero we never knew we needed. It’s like a tiny convection oven that crisps up fries, roasts veggies, and even bakes desserts with minimal oil. But with all this versatility, one question keeps popping up: Can a Pyrex dish go in an air fryer? If you’re anything like me, you’ve probably stared at your favorite glass casserole dish, wondering if it can brave the intense heat of your air fryer. After all, Pyrex is a kitchen staple — it’s durable, microwave-safe, and oven-safe… but what about this newfangled countertop gadget?

I remember the first time I tried it. I had a leftover mac and cheese I wanted to reheat, and instead of waiting 20 minutes in the oven, I thought, Why not pop it in the air fryer for a quick crisp? I grabbed my trusty Pyrex dish, loaded it up, and set the timer. Five minutes in, I started to panic. Was the glass going to crack? Was I about to ruin a perfectly good dish — and possibly my air fryer? That moment sparked my journey into understanding the science, safety, and best practices behind using Pyrex in air fryers. And today, I’m sharing everything I’ve learned, so you don’t have to learn the hard way.

Understanding Pyrex: What Makes It Special?

What Is Pyrex Made Of?

Pyrex is a brand name that’s become synonymous with heat-resistant glass cookware. But not all Pyrex is created equal. Originally, Pyrex was made from borosilicate glass, a type of glass that contains boron trioxide. This special composition makes it highly resistant to thermal shock — meaning it can go from the freezer to the oven without cracking.

However, since the 1980s, most Pyrex sold in the U.S. and Canada has been made from soda-lime glass, which is cheaper to produce but less resistant to sudden temperature changes. This is a critical distinction. While soda-lime glass is still oven-safe, it’s more vulnerable to thermal shock than borosilicate.

Here’s a quick tip: Look at the bottom of your Pyrex dish. Older pieces (pre-1990s) often say “Pyrex” in cursive and may be made of borosilicate. Newer ones (CorningWare brand) typically use soda-lime. If you’re unsure, assume it’s soda-lime and treat it with extra caution.

Thermal Shock: The Hidden Danger

Thermal shock happens when one part of a glass dish heats up faster than another. For example, if the bottom of your Pyrex dish touches a hot air fryer basket while the top is still cold, the uneven expansion can cause it to crack or even shatter.

This is why sudden changes — like taking a dish from the freezer and placing it directly into a hot air fryer — are a big no-no. Even if your Pyrex is labeled “oven-safe,” that doesn’t guarantee it can handle the rapid, concentrated heat of an air fryer.

I learned this the hard way when I tried to cook frozen lasagna in my Pyrex. The edges cracked within minutes. Lesson learned: Always bring glass dishes to room temperature before using them in high-heat appliances.

Pyrex Safety Ratings and Labels

Most Pyrex dishes are labeled as oven-safe up to 425°F (220°C). Some newer models can handle up to 450°F (230°C). But here’s the catch: Air fryers often reach 400°F (205°C) and higher, and they heat much faster than conventional ovens.

Additionally, air fryers use convection heating, which means hot air is blown directly onto the food — and the dish. This creates a more intense, direct heat than a traditional oven, increasing the risk of thermal shock.

So, while your Pyrex might survive a 30-minute bake in the oven at 400°F, the same dish might crack in an air fryer at the same temperature due to the faster heat transfer and air circulation.

Air Fryer Mechanics: How Heat Works in a Small Space

The Science of Convection Heating

Air fryers work by circulating superheated air around food using a powerful fan. This mimics deep frying by creating a crispy exterior without submerging food in oil. The heating element (usually at the top) heats the air, and the fan pushes it down and around the food.

This rapid, intense heat is great for food — but it’s tough on glass. Unlike ovens, which heat more gradually and evenly, air fryers can create hot spots, especially near the heating element.

Think of it like this: In an oven, heat rises and fills the space. In an air fryer, heat is forced — like a hairdryer blowing hot air at your dish. This means the surface of your Pyrex dish can heat up much faster than the inside, increasing the risk of cracking.

Temperature and Timing Differences

Most air fryers heat up to 400°F (205°C) in under 5 minutes. Some high-end models go up to 450°F (230°C). Compare that to a conventional oven, which can take 10–15 minutes to reach the same temperature.

This rapid preheating is efficient, but it’s hard on glass. Pyrex dishes need time to adjust to temperature changes. When you place a room-temperature Pyrex dish into a hot air fryer, the outer layer heats up instantly while the inner layer lags behind. This stress can cause microfractures — tiny cracks that may not be visible but weaken the glass over time.

For example, I once tried to bake a quiche in a 10-inch Pyrex pie dish. The air fryer was preheated to 375°F (190°C), and I placed the dish in without letting it warm up first. After 8 minutes, I heard a faint ping — and found a hairline crack along the edge. Not a disaster, but a clear warning sign.

Air Fryer Basket Design and Heat Distribution

Air fryer baskets are typically made of metal with a non-stick coating. They’re designed to allow hot air to flow through the sides and bottom. When you place a Pyrex dish inside, the glass sits directly on the metal basket or a metal tray — which is already hot.

This direct contact is a problem. Metal conducts heat very well, so the bottom of your Pyrex dish can heat up much faster than the rest. Even if the air temperature is 375°F, the metal basket might be closer to 400°F, creating a thermal gradient that stresses the glass.

Some air fryers come with a non-stick tray or baking dish insert designed for baking. These are usually metal, but they’re often thicker and more insulated than the basket itself. If your model includes one, it’s a safer choice than placing Pyrex directly on the basket.

Can You Use Pyrex in an Air Fryer? The Verdict

Short Answer: Yes, But With Conditions

So, can a Pyrex dish go in an air fryer? The answer is yes — but with important caveats. You can use Pyrex in an air fryer, but you must follow specific safety rules to avoid cracking, shattering, or damaging your appliance.

Here’s the golden rule: Only use Pyrex dishes that are explicitly labeled as oven-safe and designed for baking. Avoid using them with sudden temperature changes.

When It’s Safe to Use Pyrex

You can safely use Pyrex in an air fryer if:

• It’s at room temperature before going in.
• The air fryer is preheated to the cooking temperature.
• The Pyrex dish is not touching the heating element or sides of the basket.
• You’re cooking at 375°F (190°C) or lower.
• You’re using a dish with low sides (to allow airflow) or a special air fryer-safe baking dish.
• You’re cooking for shorter durations (under 20–25 minutes).

For example, I’ve successfully used a small 8-inch Pyrex pie dish to bake mini quiches and reheat casseroles — but only after letting the dish warm up on the counter for 10 minutes and preheating the air fryer.

When to Avoid Pyrex

Avoid using Pyrex in these situations:

• The dish is chilled or frozen (from the fridge or freezer).
• You’re cooking at 400°F (205°C) or higher.
• The dish is large or deep (e.g., 9×13 casserole dish), which blocks airflow.
• The air fryer is not preheated (causing sudden temperature shock).
• The dish is scratched, chipped, or damaged (weak spots are more likely to crack).

One reader shared a horror story: They tried to cook a frozen lasagna in a deep Pyrex dish at 400°F. The dish shattered halfway through, sending glass shards into the air fryer basket. Not only was the meal ruined, but they had to clean up broken glass and buy a new dish.

Best Practices for Using Pyrex in Air Fryers

If you decide to use Pyrex, follow these steps to stay safe:

1. Preheat your air fryer to the cooking temperature.
2. Let your Pyrex dish sit at room temperature for 10–15 minutes.
3. Use a trivet or oven-safe silicone mat to create a buffer between the dish and the hot basket.
4. Place the dish in the center of the basket, not touching the sides or heating element.
5. Start with lower temperatures (350–375°F) and shorter times.
6. Check the dish frequently for any signs of stress (cracking, bubbling, or discoloration).

I also recommend using a lid or air fryer-safe cover (like a silicone lid) to trap moisture and reduce direct heat exposure. This helps prevent the top of the dish from overheating.

Safer Alternatives to Pyrex in Air Fryers

Air Fryer-Safe Baking Dishes

If you’re worried about Pyrex, consider using dishes specifically designed for air fryers. These are usually made from:

• Ceramic – Heat-resistant and great for even cooking. Look for oven-safe ceramic dishes (up to 450°F).
• Silicone – Flexible, non-stick, and immune to thermal shock. Perfect for baking and reheating.
• Cast iron – Retains heat well and can go from air fryer to table. Use a small skillet or ramekin.
• Oven-safe metal – Like stainless steel or aluminum baking pans. These conduct heat quickly but are durable.

I switched to a ceramic 8-inch pie dish for my air fryer baking. It’s lighter than cast iron, doesn’t crack, and cleans up easily. Plus, it fits perfectly in my 5.8-quart air fryer.

Silicone: The Underrated Hero

Silicone baking molds and trays are my go-to for air fryer cooking. They’re:

• Heat-resistant up to 428°F (220°C)
• Flexible and easy to remove food from
• Lightweight and stackable for storage
• Safe for sudden temperature changes

I use silicone muffin cups to bake mini frittatas and a silicone loaf pan for banana bread. No cracking, no sticking — just easy, mess-free cooking.

When to Stick with Metal

For high-heat cooking (like crisping chicken or roasting veggies), stick with metal. Air fryer baskets are designed for metal, and it handles the heat best. Use:

• Aluminum foil (shaped into a small tray)
• Oven-safe stainless steel bowls
• Disposable aluminum pans (for easy cleanup)

Just avoid covering more than 50% of the basket with a solid pan — airflow is essential for crispy results.
