You prepped tonight's casserole in your go-to dish, but first, find out if that Pyrex is oven-safe.
Is It Safe to Use Your Pyrex in the Oven?
Updated on Apr. 28, 2024
Pyrex dishes of all kinds are essential parts of my cooking and baking routines. I use my favorite vintage Pyrex bowls to stir up biscuits and my go-to 13×9 pan to make family-favorite chicken parm sliders.
It wasn’t until the other week when I prepped a small-batch macaroni and cheese in my favorite vintage Pyrex casserole dish that I asked myself, wait, is Pyrex oven-safe—especially my vintage Pyrex?
Is Pyrex Oven-Safe?
Since it came on the scene in 1915, Pyrex was designed to be oven-safe. These glass vessels, which range from casserole dishes to pie plates to loaf pans are all safe for baking.
This being said, you do need to follow one major rule when using Pyrex: Avoid extreme temperature changes. Shifts from one extreme to the other can cause thermal shock to the dish which can cause it to crack or shatter entirely.
Can Pyrex Go from Fridge to Oven?
While a move from the fridge to a 350ºF oven likely won’t cause any damage to your Pyrex dishes, I recommend erring on the side of caution. Avoid extreme temperature changes, and let your prepped enchiladas rest on the counter for 15 to 30 minutes before putting it in the oven. That’s about the time it takes for the oven to preheat.
And another word on preheating: Pyrex recommends only placing their bakeware in an oven that’s already heated. These dishes are designed for the heat of the oven, of course, but the company explains that pans “can break when exposed to the direct heat element while the oven is preheating.”
Can Pyrex Go from Freezer to Oven?
Let me answer this one with an emphatic no! If the Great Lasagna Disaster of 1999 taught me anything, it’s that an ice-cold Pyrex pan cannot go into a hot oven.
What’s the Great Lasagna Disaster, you ask? As a kid, I was instructed to defrost a homemade lasagna and put it in the oven for dinner. However, I completely forgot about that make-ahead dish in the freezer and rushed to stuff it (frost and all) right into a 400ºF oven. In an instant, the whole thing shattered leaving a gooey, cheesy, glass-shard-filled mess all over the bottom of the oven.
In sum: Do not go from extreme cold to extreme heat. If you have a dish that’s frozen in a Pyrex pan, set a reminder on your phone or place a sticky note on your mirror so you don’t forget to defrost your dishes in advance.
Is Vintage Pyrex Oven-Safe?
I know that vintage Pyrex collections are very special. You don’t want to risk ruining one of your most treasured heirloom kitchen items while making a weeknight supper. But rest easy—vintage Pyrex dishes are oven-safe.
As long as you follow the same guidelines above, vintage Pyrex is A-OK to go in the oven and can be used in oven temperatures up to 425ºF (and skip the broiler).
There is one caveat to using your vintage Pyrex, though: Do not use any vintage dishes that are chipped or cracked—in the oven or otherwise. Heating, washing and generally using items with these sorts of flaws can cause the dishes to crack entirely or release more chips of glass. You don’t have to toss these pieces, especially if they’re close to your heart, but use them for display only.
And if you have any scuffs on your old dishes from Gran, here’s how to remove scratches from Pyrex.
Other Tips for Using Pyrex
Now that you know the answer to the question is Pyrex oven-safe?, you may want to brush up on a few other tips for using this kitchen must-have right from Pyrex.
- Don’t place a hot pan in cold water: The thermal shock can cause the pan to crack. Let your pan rest until it’s cool enough to touch before plunging it into the sink. This tip goes for all kinds of cookware, not just Pyrex!
- Don’t place a hot pan on the counter: Always place hot Pyrex dishes on a hot pad or trivet. This is to protect the pan from thermal shock and your countertop from any damage.
- Let the dish come to room temperature before freezing: If you’ve made a casserole in advance and want to freeze it for later, kudos to you for prepping! Let your pre-made recipe come to room temp before wrapping and freezing.
- Don’t use Pyrex on the stovetop: This heat is too extreme for these glass dishes.
The name of the game here is avoiding those extreme temperature variations. With a little care, your Pyrex will last you a long time. Who knows: Maybe my Pyrex casserole dish will be a coveted item in my future grandchildren’s kitchens!
