20 Things You Should Never Put in the Oven

Imagine the enticing aroma of freshly baked bread, the sizzle of a perfectly roasted chicken, or the joy of pulling out a golden brown batch of cookies from your oven. The oven is indeed a magical appliance, capable of transforming raw ingredients into mouthwatering delights. However, not everything is meant to be baked, broiled, or roasted in this culinary wonder. In this guide, we’ll explore the art of mastering the oven by revealing the 20 things you should never put in it.

The Expertise Behind Your Oven Wisdom

Before we dive into the list, let’s ensure you have confidence in the advice you’re about to receive. Our insights come from experts in the culinary world, and we’ve consulted well-established consensus on scientific topics related to cooking and kitchen safety. Your culinary journey is about to get a whole lot more exciting, and you’ll be equipped with the knowledge to use your oven wisely.

1. Plastic Utensils and Containers

Plastic and extreme heat are not a harmonious duo. Melting plastic releases harmful chemicals into your food and the air. Stick to microwave-safe containers for reheating, and save your oven for heat-resistant materials.

2. Aluminum Foil on the Bottom

Lining the oven floor with aluminum foil might seem like a clever cleanup hack, but it can disrupt heat circulation and damage your oven’s heating elements. Opt for oven-safe liners instead.

3. Non-Oven Safe Glass

While some glass dishes are designed for the oven, not all are created equal. Ordinary glassware can shatter when exposed to rapid temperature changes. Invest in oven-safe glassware to avoid a kitchen catastrophe.

4. Empty Baking Sheets

A common mistake is putting an empty baking sheet in the oven for preheating. This can lead to warping and damage. Always have something on the sheet, even if it’s just a piece of parchment paper.

5. Mason Jars with Unvented Lids

Mason jars are charming, but don’t forget to remove their metal lids before putting them in the oven. The lack of ventilation can cause the jar to explode.

6. Anything Wet in a Deep Fryer

Deep fryers and water don’t mix. Never put wet or damp food into a deep fryer; it can cause dangerous oil splatters.

7. Bread Dough That Overflows

Baking bread is a delightful endeavor, but if your dough overflows in the oven, it can create a sticky mess and even start a fire. Use an appropriate pan size and follow recipes carefully.

8. Styrofoam Containers

Styrofoam is not designed for high temperatures, and heating it in the oven can release toxic fumes. Transfer leftovers to an oven-safe container before reheating.

9. Eggs in Their Shells

Cracking eggs directly onto an oven tray is a recipe for disaster. The eggs can explode due to steam buildup. Instead, poach, bake, or boil them in a safe container.

10. Paper Bags

Baking your favorite treats in a paper bag may sound rustic, but it’s also a fire hazard. Stick to parchment paper for safe baking.

11. Delicate Herbs and Spices

The oven’s high heat can quickly turn delicate herbs and spices into a bitter mess. Add these after cooking to preserve their flavor.

12. Fresh Fruits and Vegetables with High Water Content

Items like watermelon and cucumbers may seem tempting to roast, but their high water content will turn them into mush. Stick to grilling or sautéing instead.

13. Glass Coffee Pots

If your coffee pot has a glass decanter, don’t use it in the oven. The rapid temperature change can cause it to shatter. Opt for oven-safe coffee carafes instead.

14. Wet Oven Mitts and Towels

It’s essential to keep your oven mitts and towels dry. Wet fabric can transfer heat and lead to burns.

15. Makeup and Art Supplies

Artistic endeavors should stay out of the oven. Makeup and art supplies can release harmful fumes when heated.

16. Glazed Ceramic Dishes

Ceramic dishes with decorative glazes may contain lead or other toxins. Play it safe and use only ceramics labeled as oven-safe.

17. Nonstick Cookware

While nonstick pans are fantastic for stovetop cooking, they’re not meant for the oven at high temperatures. Excessive heat can release harmful fumes and damage the nonstick coating.

18. Plastic Water Bottles

Reusing plastic water bottles by placing them in the oven to sterilize them is a big no-no. The plastic can release chemicals into the water.

19. Closed Glass Containers

Much like mason jars, sealed glass containers can explode when heated. Always vent containers by leaving the lid slightly open.

20. Wet Oven Mitts and Towels

We’ve mentioned it before, but it’s worth repeating: never put wet oven mitts and towels in the oven. Dry them thoroughly to avoid accidents.
