Can a Glass Dish Go in an Air Fryer? Find Out Here

So, you just pulled out your favorite glass baking dish—the one you’ve used for lasagna, casseroles, and even those gooey chocolate brownies—and you’re wondering: *Can a glass dish go in an air fryer?* You’re not alone. This question pops up all the time, especially as air fryers continue to dominate kitchen counters across the country. They’re fast, efficient, and make everything from frozen fries to chicken wings taste like they’ve been deep-fried… without the oil.

But here’s the thing: air fryers work differently than ovens or microwaves. They use rapid air circulation to cook food from all sides, creating a crispy exterior while keeping the inside juicy. That high-speed airflow and intense heat can be a game-changer—but it also raises concerns about safety, especially when using materials like glass. You don’t want to be the person who cracks a dish mid-cook or worse, starts a fire. So let’s cut through the confusion and get real answers. In this guide, we’ll explore whether glass is air fryer-safe, what types work best, and how to avoid kitchen disasters—all while keeping things simple and relatable.

How Air Fryers Work and Why Materials Matter

Understanding the Air Fryer’s Cooking Mechanism

Before we dive into glass, it helps to understand how your air fryer actually works. Think of it like a mini convection oven. A heating element warms the air, and a powerful fan circulates that hot air around your food at high speed. This process, called convection cooking, crisps up the outside while cooking the inside evenly. Most air fryers reach temperatures between 175°F and 400°F (80°C to 205°C), depending on the model and setting.

Because of this intense, direct airflow, the materials you use matter more than you might think. Unlike a slow oven, where heat builds gradually, an air fryer hits your dish with hot air almost immediately. This rapid temperature shift can stress certain materials—especially if they’re not designed to handle it.

Why Material Choice Affects Safety and Performance

Not all cookware reacts the same way to sudden heat. Some materials expand quickly when hot, while others conduct heat slowly. Glass is a great example. It’s non-reactive, easy to clean, and lets you see your food—but it’s also sensitive to thermal shock. That’s when a material expands or contracts too fast due to temperature changes, leading to cracks or even shattering.

For instance, imagine placing a cold glass dish straight from the fridge into a 400°F air fryer. The outside heats up fast, but the inside stays cool. This uneven expansion creates stress points, and *crack*—your dish is toast. Even if it survives the first round, repeated use under these conditions can weaken it over time.

Pro tip: Always let your glass dish come to room temperature before using it in an air fryer. And never place a hot dish on a cold surface (like a granite countertop) right after cooking.

Is All Glass Safe for Air Fryers?

Types of Glass Used in Cookware

Not all glass is created equal. Some types are built to handle extreme temperature swings, while others are best left for cold storage or room-temperature use. Here are the most common types of glass you’ll find in kitchenware:

• Borosilicate glass: This is the gold standard. Found in brands like Pyrex (original formula) and Duralex, it contains boron trioxide, which makes it resistant to thermal shock. It can handle sudden temperature changes much better than regular glass.
• Soda-lime glass: This is the most common type of glass used in everyday dishes. It’s affordable and durable for normal use, but it has low thermal resistance. Most modern Pyrex and Anchor Hocking products are made from tempered soda-lime glass, which is stronger—but still not as resilient as borosilicate.
• Tempered glass: This is soda-lime glass that’s been heat-treated to increase strength. It’s more resistant to breakage from impact, but it still has limitations when it comes to rapid heating and cooling.

The key takeaway? If you’re using glass in an air fryer, borosilicate glass is your safest bet. It’s designed for oven and stovetop use and can handle the kind of temperature swings an air fryer dishes out.

What the Manufacturers Say (And What They Don’t)

Here’s where things get tricky. Many glass dish manufacturers don’t explicitly state whether their products are air fryer-safe. You’ll often see labels like “oven-safe” or “microwave-safe,” but rarely “air fryer-safe.” Why? Because air fryers are relatively new, and safety standards haven’t fully caught up.

However, if a glass dish is labeled as oven-safe up to 450°F and made of borosilicate or tempered glass, it’s generally safe for air fryer use—with some caveats. For example, the original Pyrex (borosilicate) can handle air fryer temperatures, but the newer Pyrex (tempered soda-lime) may not be as reliable under rapid heating.

One user shared: “I used my old Pyrex casserole dish in my Cosori air fryer to make mac and cheese. It worked great—no cracks, no smoke. But when I tried the same with a newer Pyrex dish from my set, it cracked after just one use. I learned my lesson: check the glass type, not just the brand.”

Red Flags to Watch For

Before tossing any glass dish into your air fryer, ask yourself these questions:

• Is the dish chipped or scratched? Even small flaws can become weak points under heat stress.
• Is it lid included? Glass lids are usually not air fryer-safe because they trap steam and can shatter. Use a silicone or metal cover instead.
• Is the dish too large or deep? Air fryers rely on airflow. A deep dish might block circulation, leading to uneven cooking and overheating in spots.

If you answered “yes” to any of these, consider using a different dish or switching to an air fryer-safe alternative (more on that later).

Best Practices for Using Glass in an Air Fryer

Preheat and Pre-Warm Your Dish

One of the simplest ways to prevent thermal shock is to pre-warm your glass dish before adding it to the air fryer. Here’s how:

1. Let the dish sit at room temperature for at least 30 minutes.
2. Preheat your air fryer to 350°F (175°C) for 5 minutes.
3. Place the empty glass dish inside for 2–3 minutes to warm up gradually.
4. Add your food and continue cooking as usual.

This small step makes a big difference. It reduces the temperature gap between the dish and the air fryer, minimizing stress on the glass.

Choose the Right Size and Shape

Air fryers work best when air can circulate freely around the food. A dish that’s too big or too deep can block airflow, leading to hot spots and uneven cooking. Here’s what to look for:

• Size: Use a dish that’s at least 1 inch smaller than the air fryer basket on all sides. For a 5.8-quart basket, a 7-inch round or 6×8-inch rectangular dish works well.
• Shape: Shallow dishes (under 2 inches deep) allow better airflow. Deep casserole dishes may cook the top too fast while the bottom stays undercooked.
• Material thickness: Thicker glass (like 1/4 inch) handles heat better than thin, flimsy dishes.

Example: I once tried making a deep-dish quiche in a 3-inch glass pie pan. The crust burned on the outside, but the center was still runny. Switching to a 1.5-inch deep dish fixed the problem instantly.

Monitor Cooking Time and Temperature

Glass dishes can affect cooking time. Because glass retains heat well, food may cook faster than expected—or slower, if the dish is too cold. Here are a few tips:

• Lower the temperature: Reduce the air fryer temp by 25°F (about 15°C) compared to a metal pan. Glass doesn’t conduct heat as quickly as metal, so it may take longer to start cooking.
• Check early: Start checking your food 5–7 minutes before the recipe suggests. Glass can cause browning to happen faster on the surface.
• Stir or rotate: For even cooking, stir or flip ingredients halfway through, especially in deeper dishes.

One reader shared: “I used my glass loaf pan to make banana bread in my Ninja air fryer. I set it for 350°F, but after 20 minutes, the top was black and the inside was raw. Now I use 325°F and cover the top with foil after 15 minutes. Perfect every time.”

Alternatives to Glass: What Else Can You Use?

Air Fryer-Safe Materials You Should Consider

While glass can work, there are other materials that are often safer and more efficient in an air fryer. Here are the top alternatives:

Material	Pros	Cons	Best For
Silicone	Flexible, non-stick, heat-resistant up to 450°F, easy to clean	Can absorb odors, not as rigid, may wobble in basket	Muffins, egg bites, small cakes
Metal (stainless steel, aluminum)	Excellent heat conduction, durable, promotes browning	Can scratch basket coating, not non-stick (unless coated)	Roasting veggies, baking cookies, reheating leftovers
Cast iron	Retains heat well, creates crispy crusts, oven-to-table	Heavy, may rust, not suitable for all air fryer models	Baking, searing, slow cooking
Ceramic	Attractive, non-reactive, oven-safe	Can crack under thermal shock, heavy	Casseroles, quiches, desserts

For example, I love using small silicone molds for making air fryer egg bites or mini meatloaves. They pop out easily, clean up in seconds, and never crack. But if I’m making a family-sized casserole, I’ll use a lightweight metal baking pan—it browns evenly and doesn’t block airflow.

When to Stick With Glass (And When to Avoid It)

Glass still has its place. It’s perfect for:

• Dishes you want to serve directly from the dish (no messy transfers)
• Foods with high moisture content (like casseroles or quiches)
• Recipes that benefit from slow, even heating (e.g., baked oatmeal)

But avoid glass when:

• You’re cooking something that needs a crusty, crispy top (metal or cast iron works better)
• You’re using a very deep dish that blocks airflow
• You’re short on time and can’t pre-warm the dish

Real talk: I keep a small glass pie pan just for my air fryer. It’s borosilicate, shallow, and perfect for individual quiches. But for everything else? I reach for silicone or metal.

Common Mistakes and How to Avoid Them

Putting Cold Glass in a Hot Air Fryer

This is the #1 mistake—and the most dangerous. Cold glass + hot air = thermal shock. Even if the dish doesn’t crack right away, it can develop micro-fractures that weaken it over time.

Solution: Always let your glass dish sit at room temperature before use. If you’ve been storing it in a cold pantry or fridge, give it at least 30 minutes to warm up.

Using the Wrong Dish Size

A dish that’s too big blocks airflow. A dish that’s too small leaves food exposed to direct heat, causing burning.

Solution: Use the “1-inch rule”: leave at least 1 inch of space between the dish and the air fryer walls. This ensures hot air can circulate freely.

Ignoring Lids and Covers

Glass lids trap steam, which can cause pressure buildup and shattering. Metal lids can get too hot and damage the basket.

Solution: Use a perforated silicone lid or a small piece of parchment paper to cover food without blocking airflow. Or, use foil—but only if it’s not touching the heating element.

Overloading the Dish

Too much food in a glass dish can lead to uneven cooking. The center stays cold while the edges burn.

Solution: Fill the dish no more than 2/3 full. Stir or flip food halfway through cooking for even results.

Final Thoughts: Yes, Glass Can Go in an Air Fryer—But Do It Right

So, can a glass dish go in an air fryer? Yes—but only if it’s the right kind of glass, used the right way. Borosilicate glass dishes that are oven-safe, shallow, and free of cracks can work beautifully. Just remember to pre-warm the dish, choose the right size, and monitor cooking closely.

That said, don’t force it. If you’re unsure about a dish, test it with a simple recipe first—like a small batch of roasted veggies. And if you’re making something that needs a crispy top or fast browning, consider switching to metal, silicone, or ceramic.

The beauty of air fryers is their versatility. They’re not just for frozen snacks—they can handle full meals, baked goods, and even delicate dishes. But with great power comes great responsibility. By understanding how materials interact with your air fryer, you’ll avoid kitchen mishaps and enjoy safer, tastier results every time.

At the end of the day, your glass dish isn’t the enemy. It’s a tool—one that can work perfectly in your air fryer, as long as you treat it with care. So go ahead, experiment, and find what works best for your kitchen. Just remember: slow and steady wins the race… especially when it comes to glass and heat.
