Can You Put a Glass Bowl in the Air Fryer Safely? Let’s Talk About It

You’ve probably found yourself standing in the kitchen, air fryer humming, and staring at that leftover lasagna in a glass bowl. The thought crosses your mind: “Can I just pop this right into the air fryer and save myself the hassle of transferring it to another dish?” You’re not alone. It’s a common question, especially when you’re juggling a busy schedule and just want a quick, crispy reheat.

I’ve been there too—trying to streamline my cooking process while avoiding a kitchen disaster. After a few close calls (and one unfortunate cracked casserole dish), I decided to dig into the science and safety behind using glass in the air fryer. Turns out, the answer isn’t a simple yes or no. It depends on the type of glass, the temperature, and how you use it. In this post, we’ll explore the ins and outs of using glass bowls in your air fryer, so you can make smart, safe choices without sacrificing convenience.

Understanding How Air Fryers Work

The Science Behind Rapid Air Circulation

Before we dive into glass compatibility, let’s take a quick look at how air fryers actually work. Unlike traditional ovens that rely on radiant heat from heating elements, air fryers use rapid air circulation to cook food. A high-powered fan pushes hot air (usually between 300°F and 400°F) around the food in a confined basket or tray. This creates a crispy, fried-like texture without the need for oil.

This method is fast, efficient, and great for achieving that golden crunch. But it also means the heat is intense and direct—especially on the surface of the food and any container holding it. Unlike a slow-heating oven, an air fryer can go from room temperature to 400°F in under 5 minutes. That’s a rapid thermal shock for any material, including glass.

Why Container Choice Matters

The container you use in an air fryer isn’t just about convenience—it’s about safety and performance. The air fryer’s heating element is close to the cooking chamber, and the fan creates strong airflow. If your container isn’t designed for this environment, it can:

• Crack or shatter due to sudden temperature changes
• Interfere with airflow, leading to uneven cooking
• Leach chemicals (especially if not food-safe or oven-safe)
• Damage the air fryer’s non-stick coating

So, while you might be tempted to reuse that leftover glass bowl from the fridge, it’s important to ask: Is this glass built to handle the air fryer’s unique environment?

Common Misconceptions

Many people assume that if a glass dish is “oven-safe,” it’s automatically safe for an air fryer. But that’s not always the case. Ovens heat slowly and evenly, while air fryers deliver intense, focused heat in a smaller space. I once used a Pyrex dish I’d used in the oven for years—only to hear a loud crack halfway through cooking. The dish survived the oven, but the air fryer’s rapid heating was too much for it.

Another myth is that all glass is the same. In reality, there are different types of glass with varying heat tolerances. Knowing the difference can save you from a messy cleanup and potential injury.

Types of Glass and Their Heat Tolerance

Tempered Glass (Borosilicate vs. Soda-Lime)

Not all glass is created equal. The two most common types of heat-resistant glass are borosilicate glass and soda-lime glass (tempered). Here’s how they differ:

• Borosilicate glass (e.g., Pyrex, Duralex): Made with boron trioxide, this glass can handle extreme temperature changes. It’s used in laboratories and high-end bakeware. It typically withstands temperatures from -40°F to 572°F and is highly resistant to thermal shock.
• Soda-lime glass (tempered) (e.g., many store-bought glass bowls, Mason jars): While tempered for strength, it’s not as heat-resistant as borosilicate. It can handle oven temperatures (usually up to 350°F–400°F), but rapid temperature changes (like placing a cold dish into a preheated air fryer) can cause it to crack.

Tip: Check the bottom of your glass bowl. If it says “borosilicate” or “tempered borosilicate,” it’s a safer bet for air fryer use. If it just says “tempered glass” or “oven-safe,” proceed with caution.

Oven-Safe vs. Air Fryer-Safe: What’s the Difference?

Here’s a key distinction: Oven-safe doesn’t always mean air fryer-safe. Ovens heat gradually, giving glass time to expand evenly. Air fryers, on the other hand, can go from cold to 400°F in minutes. This rapid heating causes uneven expansion in the glass—leading to stress points and potential breakage.

For example, I tried using a tempered glass casserole dish (rated for 450°F in the oven) in my air fryer. I preheated the air fryer to 375°F, then added the dish straight from the fridge. Five minutes later, the dish cracked in half. The temperature difference was too much for the glass to handle.

Lesson learned: Even if a glass dish is oven-safe, it may not be designed for the rate at which an air fryer heats up.

How to Identify Safe Glassware

So, how do you know if your glass bowl is truly air fryer-ready? Here are a few tips:

• Look for labels: “Borosilicate,” “thermal shock resistant,” or “air fryer safe” are good signs.
• Check the manufacturer’s website: Some brands (like Pyrex, Anchor Hocking) list air fryer compatibility.
• Test the weight: Borosilicate glass is usually thinner and lighter than tempered soda-lime glass.
• Avoid colored or decorative glass: These often contain additives that reduce heat resistance.

I keep a few small borosilicate ramekins and a 6-inch glass pie dish specifically for my air fryer. They’re clearly labeled and have survived multiple uses without issues.

When and How to Safely Use a Glass Bowl in an Air Fryer

Step-by-Step Safety Guide

If you’ve confirmed your glass bowl is borosilicate or air fryer-safe, here’s how to use it without risk:

1. Preheat the air fryer first: Set your air fryer to the desired temperature and let it run for 3–5 minutes. This ensures even heat distribution.
2. Bring the glass bowl to room temperature: Never place a cold glass bowl (especially from the fridge) into a hot air fryer. Let it sit out for 10–15 minutes.
3. Use a trivet or silicone mat: Place a heat-resistant trivet or silicone mat at the bottom of the air fryer basket. This creates a buffer and improves airflow.
4. Position the bowl in the center: Avoid letting the glass touch the heating element or fan. Keep it centered for even cooking.
5. Monitor cooking time and temperature: Stick to 350°F or lower. High heat (400°F+) increases the risk of thermal shock.
6. Remove carefully: Use silicone oven mitts or tongs. Place the bowl on a heat-safe surface—not a cold countertop.

I use this method for reheating casseroles, cooking small portions of mac and cheese, or even making individual frittatas. It works like a charm—when done right.

Best Foods to Cook in a Glass Bowl

Glass bowls are ideal for foods that benefit from even, gentle heating. Here are some great options:

• Reheating leftovers: Pasta dishes, casseroles, or stews (just stir halfway through).
• Baking small desserts: Mug cakes, chocolate lava cakes, or mini cheesecakes.
• Cooking eggs: Frittatas, quiches, or baked eggs with cheese and veggies.
• Melting or sautéing: Butter, chocolate, or small amounts of sauce (stir often to avoid hot spots).

One of my favorite tricks: I make a single-serving chocolate mug cake in a 10-ounce borosilicate ramekin. 2 minutes at 325°F, and it’s perfectly gooey in the middle with a slightly crisp top. No need to preheat the oven!

What to Avoid

Even with safe glassware, there are some things you should never do:

• ❌ Use a glass bowl that’s cracked, chipped, or has visible scratches.
• ❌ Place a cold glass bowl directly into a preheated air fryer.
• ❌ Use glass for high-heat searing (e.g., steak, chicken skin). The intense heat can cause cracking.
• ❌ Stack multiple glass bowls. This blocks airflow and increases pressure.
• ❌ Cook for long periods at 400°F+. Stick to 30–40 minutes max at 350°F.

When in doubt, opt for silicone or metal containers designed for air fryers. They’re more forgiving and often come with handles or lids for easy removal.

Alternatives to Glass Bowls in Air Fryers

Silicone Containers: The Flexible Favorite

If you’re nervous about glass, silicone containers are a fantastic alternative. They’re:

• Heat-resistant (up to 425°F or higher)
• Flexible and easy to remove
• Non-stick (great for baked goods)
• Available in various sizes and shapes

I use silicone muffin cups for mini quiches and silicone loaf pans for small meatloafs. They’re dishwasher-safe and never crack. Plus, they collapse for easy storage.

Metal and Stainless Steel Options

Metal is a natural fit for air fryers. It conducts heat well and doesn’t shatter. Look for:

• Stainless steel bowls: Durable and safe for high heat. Just avoid aluminum if it’s not food-grade.
• Cast iron skillets (small size): Perfect for searing or baking. Retains heat beautifully.
• Perforated metal pans: Allow better airflow than solid dishes.

One caveat: Metal can cause hot spots if not properly positioned. Use a silicone mat underneath to diffuse heat.

Disposable and Oven-Safe Paper Containers

For quick meals or camping, oven-safe paper containers are a lightweight option. Brands like Reynolds and If You Care make parchment-lined paper bowls that can handle 400°F. They’re great for:

• Reheating leftovers
• Portable meals
• Reducing cleanup

Just make sure they’re labeled “oven-safe” and avoid using them for long cooking times or high heat.

Real-World Examples and User Experiences

Success Stories: When Glass Works

Many home cooks have successfully used glass in air fryers—with the right precautions. Here are a few examples:

• Sarah, a busy mom: “I use my Pyrex pie dish to reheat lasagna every week. I preheat the air fryer, let the dish warm up, and cook at 325°F. It’s perfect—crispy top, hot inside, and no mess.”
• Mike, a college student: “I make mug cakes in a borosilicate ramekin. 2 minutes, and I’ve got dessert. No oven needed.”
• Lisa, a food blogger: “I tested 5 glass bowls in my air fryer. Only the borosilicate ones survived. The rest cracked within 10 minutes.”

These stories show that glass can work—but only when used correctly.

Cautionary Tales: When Glass Fails

On the flip side, there are plenty of cautionary tales:

• Tom’s shattered casserole: “I put my leftover mac and cheese in a glass bowl straight from the fridge. The air fryer was preheated to 375°F. Five minutes later, it exploded. Glass everywhere.”
• Emma’s cracked ramekin: “I used a decorative glass bowl I thought was safe. It cracked after 15 minutes. The manufacturer later confirmed it wasn’t thermal shock resistant.”

These incidents highlight the importance of temperature acclimation and material verification.
