Air fryers have revolutionized the way we cook, offering a faster, healthier, and more convenient alternative to traditional frying methods. Their compact size and rapid air circulation create crispy, delicious food with minimal oil. But as with any new kitchen appliance, questions arise regarding the compatibility of different cookware. One of the most common questions is: Can you safely put a Pyrex dish in an air fryer? This article delves deep into the nuances of using Pyrex in an air fryer, providing a comprehensive understanding of the factors involved and offering practical guidelines for safe and successful air frying.
Understanding Pyrex and its Heat Resistance
Pyrex, a household name synonymous with durable glassware, has been a kitchen staple for over a century. Its reputation for heat resistance makes it a popular choice for baking, roasting, and microwaving. However, it’s crucial to understand the composition and properties of Pyrex to determine its suitability for use in an air fryer.
The Composition of Pyrex: Borosilicate vs. Soda-Lime Glass
Originally, Pyrex was manufactured using borosilicate glass, known for its exceptional resistance to thermal shock. Thermal shock occurs when a material experiences a sudden and significant temperature change, leading to stress and potential breakage. Borosilicate glass contains boron trioxide, which gives it a lower coefficient of thermal expansion compared to other types of glass. This means it expands and contracts less when exposed to temperature fluctuations.
However, in the latter half of the 20th century, the manufacturing process for Pyrex in some regions, including the United States, shifted to using soda-lime glass. Soda-lime glass is a less expensive alternative to borosilicate glass. While still relatively heat-resistant, it is more susceptible to thermal shock. This change in composition has led to some confusion and concern regarding the safety of using Pyrex in high-heat environments like air fryers.
Thermal Shock and Glassware: What You Need to Know
Thermal shock is the primary concern when using any type of glassware, including Pyrex, in an air fryer. The rapid heating and cooling cycles within an air fryer can create significant temperature gradients within the glass, potentially leading to cracking or shattering.
The risk of thermal shock is influenced by several factors, including the type of glass, the thickness of the glass, the temperature difference, and the presence of any existing imperfections in the glass.
Air Fryers and Heat Distribution
Air fryers operate by circulating hot air rapidly around the food, creating a convection-like cooking environment. This intense heat circulation is what gives food its crispy exterior. Understanding how heat is distributed within an air fryer is vital for determining the suitability of different cookware.
The Convection Cooking Environment
The high-speed air circulation within an air fryer results in faster and more even cooking compared to traditional ovens. This is because the hot air is constantly in contact with the food’s surface, promoting efficient heat transfer. However, this rapid heating can also create temperature differentials within cookware, particularly if the cookware is not designed to withstand such rapid temperature changes.
Temperature Fluctuations in Air Fryers
While air fryers offer precise temperature control, the actual temperature inside the appliance can fluctuate depending on factors like the food load, the initial temperature of the food, and the air fryer’s heating element. These temperature fluctuations, combined with the rapid heating and cooling cycles, can exacerbate the risk of thermal shock.
Is It Safe to Use Pyrex in an Air Fryer? Guidelines and Considerations
The question of whether you can safely use Pyrex in an air fryer doesn’t have a simple yes or no answer. It depends on several factors, including the type of Pyrex, the specific air fryer model, and the cooking conditions. Here’s a breakdown of the key considerations:
Identifying Your Pyrex: Borosilicate or Soda-Lime?
Determining whether your Pyrex is made of borosilicate or soda-lime glass is crucial. Older Pyrex dishes are more likely to be made of borosilicate glass, while newer dishes, particularly those manufactured in the US after the shift in production, are often made of soda-lime glass. Unfortunately, it is generally difficult to ascertain the glass type just by looking at it. However, some resources online may provide clues based on the manufacturing date or location indicated on the dish.
Reading the Manufacturer’s Instructions
Always consult the manufacturer’s instructions for both your Pyrex dish and your air fryer. The manufacturer’s guidelines are the most reliable source of information regarding the safe usage of their products. If the Pyrex dish is explicitly stated to be oven-safe, it is likely but not guaranteed to be suitable for use in an air fryer, assuming the air fryer temperature does not exceed the maximum oven-safe temperature specified for the Pyrex. If your air fryer manual advises against using glassware, it is best to adhere to those guidelines.
Temperature Limits and Gradual Heating
Regardless of the type of Pyrex, it’s essential to avoid extreme temperature changes. Gradual heating is always preferable. This means avoiding placing a cold Pyrex dish directly into a preheated air fryer. Allowing the dish to warm up gradually can help minimize the risk of thermal shock.
Never exceed the maximum temperature recommended by the Pyrex manufacturer. This information is typically found on the bottom of the dish or in the product documentation.
Avoiding Thermal Shock: Best Practices
Here are some best practices to minimize the risk of thermal shock when using Pyrex in an air fryer:
- Preheat the air fryer gradually: Instead of setting the temperature to the desired level immediately, start at a lower temperature and gradually increase it.

Can all types of Pyrex be used in an air fryer?
Not all Pyrex dishes are created equal, and therefore, not all are suitable for air fryer use. Original Pyrex, made with borosilicate glass, is generally more resistant to thermal shock and temperature changes. However, newer Pyrex made with soda-lime glass is more prone to shattering due to rapid temperature fluctuations.
Before using any Pyrex dish in your air fryer, carefully check the bottom for markings indicating its temperature tolerance. If it explicitly states it is oven-safe, it might be okay, but proceed with caution. It’s always best to err on the side of safety and avoid using delicate or older Pyrex dishes in an air fryer, especially if you’re unsure of their material composition.
What are the risks of putting Pyrex in an air fryer?
The primary risk is shattering or cracking due to thermal shock. Air fryers heat up and cool down quickly, which can cause stress on the glass if it’s not designed to handle rapid temperature changes. This is especially true for soda-lime Pyrex, which is more susceptible to breaking under these conditions.
A shattered Pyrex dish can be dangerous, potentially causing cuts or burns from flying glass and hot food. It also makes a significant mess and renders your dish unusable. Beyond the physical danger, you also risk damaging your air fryer if glass fragments get lodged in the heating element or fan.
What temperature is safe for Pyrex in an air fryer?
There’s no universally “safe” temperature for all Pyrex in an air fryer. Older borosilicate Pyrex can withstand higher temperatures, while newer soda-lime Pyrex is more vulnerable. Even with oven-safe labeled Pyrex, it’s wise to stay well below the maximum oven temperature, especially if you’re unsure of the exact type.
As a general guideline, avoid exceeding 350°F (175°C) when using Pyrex in an air fryer. Monitor the dish closely for any signs of stress, such as small cracks or unusual noises. Start with shorter cooking times and lower temperatures, increasing them gradually only if the Pyrex appears stable.
Are there specific Pyrex dishes that are better suited for air fryers?
Smaller, newer Pyrex dishes might be more suitable than larger, older ones, simply because they tend to be made with the more resistant borosilicate glass. Individual ramekins or small baking dishes are often less prone to issues. However, this does not guarantee complete safety.
Always prioritize dishes that are specifically labeled as safe for both oven and air fryer use. Even then, closely monitor the dish during cooking for any signs of stress or damage. Consider alternative materials like metal or silicone for a safer cooking experience in your air fryer.
Can I put a cold Pyrex dish directly into a hot air fryer?
No, putting a cold Pyrex dish directly into a hot air fryer is extremely risky. This sudden temperature change can cause significant thermal shock, greatly increasing the likelihood of shattering or cracking, regardless of the Pyrex type.
Always allow the Pyrex dish to gradually come to room temperature before placing it in a preheated air fryer. This allows the glass to adjust to the temperature change more slowly, minimizing the risk of thermal stress. Even preheating the air fryer with the Pyrex inside can help, but still proceed with caution.
What are safer alternatives to Pyrex for air fryer cooking?
There are many safer alternatives to Pyrex for air fryer cooking, eliminating the risk of glass shattering. Metal baking pans, especially those made of stainless steel or aluminum, are excellent choices as they are durable and distribute heat evenly.
