Can Glass Go in an Air Fryer? Find Out Now

You’ve just pulled a delicious-looking casserole from the oven, only to realize you’re out of oven-safe dishes. The next thought? Can I just use my air fryer? And more importantly, can glass go in an air fryer? If you’ve ever stood in your kitchen, holding a glass dish and staring at your air fryer like it holds the secrets of the universe, you’re not alone. Glass is a kitchen staple—affordable, clear (so you can see your food), and easy to clean. But when it comes to air fryers, the rules aren’t as clear-cut as they are with ovens or microwaves.

Let’s be honest: air fryers are magical. They crisp chicken wings, revive leftovers, and even bake cookies—all with less oil and faster cooking times. But with great power comes great responsibility (and a few safety concerns). Glass might survive a 400°F oven, but an air fryer blasts heat from all angles, creating rapid temperature changes. That’s where things get tricky. In this post, we’ll dive into whether glass is truly safe in your air fryer, what types of glass work, and how to avoid a kitchen disaster. Whether you’re reheating lasagna or baking a mini cheesecake, you’ll walk away knowing exactly what’s safe—and what’s not.

How Air Fryers Work and Why Heat Matters

Before we answer the big question—can glass go in an air fryer—we need to understand how air fryers actually work. Unlike traditional ovens that heat food from the bottom or top, air fryers use a powerful fan to circulate hot air at high speeds. This rapid airflow creates a convection effect, cooking food evenly and giving it that crispy, fried texture without deep frying. But this method has a catch: it creates intense, direct heat that can stress certain materials, especially glass.

Convection vs. Traditional Heating

In a regular oven, heat rises slowly. Glass dishes warm gradually, reducing the risk of thermal shock (when sudden temperature changes cause cracking or shattering). But in an air fryer, the fan blasts hot air from multiple directions—top, sides, and bottom—heating the dish much faster. This rapid temperature shift is the main reason why not all glass is safe.

Think of it like stepping from a cold pool into a hot shower. Your body reacts—sometimes with a gasp. Glass does the same. If the outside of the dish heats up faster than the inside, stress builds up, and crack! you’ve got a broken dish and a mess to clean.

Temperature Ranges and Air Fryer Settings

Most air fryers operate between 175°F and 400°F (80°C to 200°C), with some models going higher. That’s a wide range, and glass reacts differently at various temperatures. For example:

• Reheating at 300°F might be safe for tempered glass

<

• Baking at 375°F could be risky if the glass wasn’t designed for it

<

• Preheating an empty glass dish is a major no-no—thermal shock is almost guaranteed

One home cook shared: “I put a regular glass pie dish in my air fryer to reheat quiche. It didn’t crack during cooking, but when I took it out and set it on a cold granite counter, it shattered. I learned the hard way that even if it survives cooking, sudden cooling can be just as dangerous.”

Types of Glass: What’s Safe and What’s Not

Not all glass is created equal. The key to answering can glass go in an air fryer lies in the type of glass you’re using. Let’s break down the most common types and their air fryer safety.

Tempered Glass (Pyrex, Anchor Hocking, etc.)

Tempered glass is your best bet. It’s heat-treated to withstand higher temperatures and sudden changes better than regular glass. Brands like Pyrex and Anchor Hocking make borosilicate or tempered soda-lime glass dishes that are oven-safe up to 425°F–450°F. These are generally safe in air fryers if you follow a few rules:

<
• Always place food in the dish before putting it in the air fryer (never preheat an empty dish)

<

• Let the dish come to room temperature before cooking (no fridge-to-air fryer moves)

<

• Use lower to medium heat settings when possible

Example: A Pyrex 8×8 baking dish works well for mini brownies or roasted veggies in a 350°F air fryer. One user reported: “I bake individual lasagnas in Pyrex ramekins at 360°F for 20 minutes—no cracks, perfect results.”

Regular Glass (Jars, Drinking Glasses, Non-Tempered)

This is where things get dangerous. Regular glass—like mason jars, drinking glasses, or non-tempered storage containers—is not designed for high heat. It’s more likely to shatter due to thermal stress. Avoid using:

• Mason jars (even if labeled “oven-safe,” they’re not meant for convection heat)
• Drinking glasses (wine glasses, tumblers)
• Non-branded glass containers with no safety labels

One Reddit user shared a cautionary tale: “I tried to cook a single-serve cake in a mason jar. It cracked halfway through, and the batter leaked into the air fryer basket. Not worth the risk!”

Oven-Safe vs. Air Fryer-Safe: A Crucial Difference

Just because a glass dish is labeled “oven-safe” doesn’t mean it’s “air fryer-safe.” Oven-safe glass is tested for radiant heat, not intense convection. Some Pyrex products have been recalled in the past due to shattering in ovens, so air fryers—with their faster, more aggressive heating—can be even riskier. Always check the manufacturer’s guidelines. If it says “not for convection ovens,” skip the air fryer.

Safe Practices When Using Glass in an Air Fryer

So, can glass go in an air fryer? Yes—but only if you follow these safety practices. Treat glass with respect, and it will serve you well. Ignore the rules, and you might end up with a kitchen hazard.

Preheating: The Biggest Mistake

Never, ever preheat an empty glass dish in the air fryer. This is the #1 cause of glass breakage. Air fryers heat up quickly, and an empty dish has no food to absorb heat, so the glass heats unevenly. Instead:

• Preheat the air fryer with the basket (empty or with a liner)
• Add the glass dish (with food inside) when the air fryer reaches temperature
• Start cooking immediately

Tip: If your recipe calls for a “preheated dish,” skip glass. Use a metal or silicone alternative instead.

Temperature Gradients: Avoid Sudden Changes

Thermal shock happens when one part of the glass heats or cools faster than another. To prevent this:

• Don’t place a hot glass dish on a cold surface (like stone counters or metal sinks)
• Use a trivet or wooden cutting board to set it down
• Don’t run cold water over a hot dish
• Let it cool gradually on a cooling rack

One mom shared: “I reheated mac and cheese in a Pyrex dish. After removing it, I set it on a silicone mat instead of the counter. No cracking, and the food stayed hot longer.”

Size and Fit: Don’t Overcrowd

Air fryers need space for air to circulate. If your glass dish is too large or too deep, it can block airflow, causing uneven cooking and overheating the glass. Choose dishes that:

• Fit comfortably with 1–2 inches of space around the sides
• Are shallow (under 2 inches deep) for better air flow
• Leave room for the basket to close properly

Example: A 7-inch round Pyrex dish works well in a 5-quart air fryer. A 9-inch dish might touch the heating element, increasing breakage risk.

Alternatives to Glass: When to Use Other Materials

Sometimes, the safest answer to can glass go in an air fryer is “not this time.” Other materials are better suited for air fryers, especially for high-heat or rapid-cooking recipes.

Silicone: The Air Fryer’s Best Friend

Silicone is flexible, heat-resistant (up to 450°F), and won’t crack from thermal shock. It’s perfect for:

• Muffins, cupcakes, and mini quiches
• Individual portions (like single-serve lasagna)
• Reheating sticky foods (no scraping needed)

Bonus: Silicone molds are lightweight and easy to clean. One user said: “I use silicone egg molds for breakfast frittatas. They pop out easily and clean up in seconds.”

Metal: Durable and Efficient

Metal dishes (aluminum, stainless steel) conduct heat quickly and evenly. They’re ideal for:

• Baking bread or rolls
• Roasting vegetables
• Frying foods that need high heat

Note: Avoid non-stick metal pans if the coating is scratched—flaking coating can be dangerous. Stick to plain, oven-safe metal.

Oven-Safe Ceramics and Stoneware

Ceramic dishes (like CorningWare or Le Creuset) are great for casseroles and baked goods. They retain heat well and are less prone to thermal shock than glass. Just make sure they’re labeled “oven-safe” and avoid sudden temperature changes.

One tip: “I use a small ceramic casserole dish for baked oatmeal. It browns evenly and stays warm longer than glass.”
