Can a Pyrex Dish Be Used in an Air Fryer Safely

Yes, a Pyrex dish can be used in an air fryer—but only if it’s labeled oven-safe and fits securely without blocking airflow. Avoid sudden temperature changes to prevent cracking, and always preheat the air fryer gradually for safe, even cooking. Never use damaged or non-oven-safe glass, as extreme heat may cause breakage.

Key Takeaways

• Check for heat resistance: Ensure your Pyrex dish is rated for air fryer temperatures (typically 400°F+).
• Preheat the dish: Warm Pyrex gradually to avoid thermal shock and cracking.
• Use oven mitts: Always handle hot Pyrex with protective gloves to prevent burns.
• Avoid sudden temperature changes: Never place cold Pyrex directly into a hot air fryer.
• Verify size and fit: Choose a dish that fits air fryer basket without blocking airflow.
• Inspect for damage: Discard chipped or cracked Pyrex to prevent breakage during cooking.

Can a Pyrex Dish Be Used in an Air Fryer Safely?

Let’s be honest—air fryers have taken over our kitchens. From crispy french fries to golden chicken wings, this countertop appliance makes cooking fast, easy, and (mostly) mess-free. But as we experiment with new recipes, one question keeps popping up: Can a Pyrex dish be used in an air fryer?

I remember the first time I tried using a Pyrex bowl in my air fryer. I was making a frittata, and my regular pan didn’t fit. The Pyrex was sitting there, clean and inviting. “Why not?” I thought. The result? A cracked dish and a kitchen full of disappointment. That moment taught me the hard way that not all kitchenware is air fryer-friendly. But don’t worry—you don’t have to learn the same lesson. Whether you’re baking, roasting, or reheating, understanding what works (and what doesn’t) in your air fryer can save you time, money, and heartbreak. So, let’s dive into the world of Pyrex, air fryers, and how to use them together—safely.

Understanding Pyrex: What Makes It Special?

What Is Pyrex Made Of?

Pyrex is a brand name that most of us associate with glass baking dishes. But did you know there are actually two types of Pyrex? The original Pyrex, developed in the early 1900s, was made from borosilicate glass—a material known for its ability to handle extreme temperature changes. This glass is resistant to thermal shock, meaning it can go from the freezer to the oven without cracking.

However, in the 1990s, many manufacturers (including the company behind modern Pyrex in the U.S.) switched to soda-lime glass for cost and manufacturing reasons. This version is more affordable and widely available, but it’s less resistant to sudden temperature changes. So, if you’re holding a Pyrex dish bought in the last 20 years, it’s likely made of soda-lime glass—not the original borosilicate.

Thermal Shock: The Real Enemy

The biggest risk when using glass in an air fryer is thermal shock. This happens when one part of the glass heats up faster than another, causing stress and cracks. Air fryers are notorious for creating rapid temperature shifts. The heating element blasts hot air at high speeds (sometimes up to 400°F), and the cooking basket can heat up in seconds.

Imagine placing a cold Pyrex dish directly into a 375°F air fryer. The outside heats instantly, but the inside stays cool. That tension? That’s thermal shock. And it’s a recipe for disaster. I’ve seen a casserole dish shatter mid-cook, sending hot food flying. Not fun.

Tip: Always check the bottom of your Pyrex dish for markings. If it says “borosilicate,” you’re in better shape. But even then, proceed with caution. If it just says “Pyrex” without specifics, assume it’s soda-lime glass.

Air Fryer Mechanics: Why Glass Matters

How Air Fryers Work

Air fryers use a powerful heating element and a fan to circulate hot air around food. This creates a crispy, fried-like texture without the need for oil. The cooking chamber is small, and the air moves at high velocity—sometimes up to 100 mph! This intense airflow means heat is distributed quickly and unevenly at first.

Unlike an oven, where heat rises slowly, an air fryer can go from room temperature to 400°F in under 5 minutes. This rapid heating is great for food, but it’s tough on glass. The edges of a Pyrex dish will heat up faster than the center, leading to stress fractures.

Heat Distribution and Airflow

Air fryers rely on convection—the movement of hot air. For best results, airflow must circulate freely around the food. If you place a large, flat Pyrex dish in the basket, it blocks airflow. This can lead to uneven cooking, longer cook times, and even overheating of the dish itself.

For example, I once tried to bake brownies in a deep Pyrex pan. The edges were burnt, the center was undercooked, and the pan cracked after cooling. The air couldn’t reach the middle, creating hot spots. Lesson learned: airflow is everything in an air fryer.

Tip: If you must use glass, choose shallow, wide dishes (like pie plates) that allow air to flow over and around the food. Avoid tall or narrow containers.

Temperature Limits and Safety

Most air fryers can reach 400°F (205°C). Pyrex glass is rated for oven use up to 425°F, so temperature alone isn’t the issue. The problem is the rate of temperature change. Pyrex can handle high heat, but not sudden shifts.

Also, some Pyrex dishes have metal rims or handles. These can get extremely hot and even melt if they touch the heating element. Always remove any non-glass components before placing in the air fryer.

Can You Use Pyrex in an Air Fryer? The Truth

Short Answer: Yes, But With Conditions

So, can a Pyrex dish be used in an air fryer safely? The answer is: yes, but only if you follow strict guidelines. It’s not a “never do this” rule, but it’s definitely a “proceed with caution” situation.

Here’s what you need to know:

• Use borosilicate glass if possible. These are more heat-resistant.
• Preheat the dish by warming it gradually. Don’t place a cold dish in a hot air fryer.
• Choose the right size. The dish should fit with at least 1 inch of space around the sides for airflow.
• Start with lower temperatures. Begin at 325°F and increase if needed.
• Never go from freezer to air fryer. Always let food and dish come to room temperature first.

When It’s Safe (and When It’s Not)

Safe uses for Pyrex in an air fryer:

• Baking small items: Think mini quiches, single-serve cakes, or stuffed mushrooms. Use shallow, wide dishes.
• Reheating leftovers: A small Pyrex bowl can reheat pasta or rice without splattering. Just cover it with foil to trap steam.
• Melting cheese or butter: A tiny Pyrex ramekin works great for garlic butter or cheese sauce.

Unsafe uses:

• Deep dishes or casseroles: These block airflow and trap heat.
• Frozen dishes: A frozen Pyrex dish can shatter instantly.
• High-fat foods: Splattering oil can cause thermal stress. Use a lid or foil.
• Large or heavy dishes: They can block the heating element or fall out when removing the basket.

Real-Life Example: My Frittata Fix

Remember my frittata disaster? I fixed it by switching to a small, wide Pyrex pie dish and preheating it for 5 minutes at 250°F before adding the eggs and cranking it to 350°F. The result? Perfectly cooked eggs, no cracks, and easy cleanup. The key was gradual heating and good airflow.

Best Alternatives to Pyrex for Air Fryers

Metal Baking Pans and Ramekins

If you’re looking for safer, more efficient options, metal is your friend. Air fryer-safe metal pans heat evenly and don’t risk thermal shock. Look for:

• Silicone-coated metal pans: These prevent sticking and are easy to clean.
• Stainless steel ramekins: Great for individual servings of custard or soufflé.
• Aluminum cake pans: Lightweight and perfect for small cakes.

Metal conducts heat faster than glass, so food cooks more evenly. Plus, it won’t crack. I’ve used a 6-inch aluminum pan for lasagna in my air fryer—came out perfectly crispy on top, hot in the middle.

Silicone Molds and Baking Cups

Silicone is a game-changer for air fryers. It’s flexible, heat-resistant (up to 450°F), and non-stick. Silicone muffin cups, mini loaf pans, and even silicone “pans” with handles work wonders.

Pros:

• No preheating needed.
• Easy to remove food.
• Dishwasher-safe.

Cons:

• Can absorb odors over time.
• May not get as crispy as metal.

I love using silicone for mini meatloaves or egg muffins. They pop out easily and clean up in seconds.

Oven-Safe Ceramics

Not all ceramics are air fryer-safe, but many are. Look for dishes labeled “oven-safe” and “microwave-safe.” Avoid ceramics with metallic trim, as they can spark or melt.

Examples:

• Stoneware ramekins: Great for crème brûlée or baked apples.
• Ceramic pie plates: Work well for small pies or quiches.

Tip: Test ceramics by preheating them with the air fryer. If they survive 10 minutes at 350°F with no cracks, they’re likely safe.

Practical Tips and Safety Checklist

How to Use Pyrex in an Air Fryer (Step-by-Step)

1. Check the dish: Look for “borosilicate” or “oven-safe to 425°F.” Avoid metal trim.
2. Bring to room temperature: Never use a cold dish. Let it sit out for 30 minutes if stored in a cold cabinet.
3. Preheat the air fryer to 250°F for 3–5 minutes.
4. Place the dish inside and preheat for another 2–3 minutes.
5. Add food and increase temperature to desired level (start low: 325°F).
6. Monitor closely: Check after 10 minutes. Adjust time or temp as needed.
7. Remove carefully: Use oven mitts. Let the dish cool before washing.

Common Mistakes to Avoid

• Skipping preheat: This is the #1 cause of cracking. Always warm the dish first.
• Overcrowding: Don’t fill the dish more than 2/3 full. Food expands when heated.
• Using wet dishes: Water on the bottom can cause steam explosions. Dry thoroughly.
• Rapid cooling: Don’t place a hot Pyrex dish on a cold surface (like a granite counter). Use a trivet or towel.
