[Answered] Are Oui Jars Oven Safe?

As the summer months roll in, you may want to add a few new pieces of cookware to your kitchen for grilling, roasting, and baking. Notably, the Oui jars are one of the latest additions from the Le Creuset brand as cookware. Using this cookware, you can bake or store any food in your kitchen. But, are oui jars oven safe for any cooking mode?

If you’ve been wondering whether your Oui jars are oven-safe in every baking mode of your oven, you have come to the right place. 

Here, we will address some of the questions around this topic and give you some excellent resources to help you make the best choice possible. All you need to ensure is that the Oui jars are being used for the proper cooking purpose.

Are The Oui Jars Oven Safe?

Quite simply, “Yes!”. The Oui jars are oven-safe; they are handmade and assembled with care, which means these jars can be used safely in an oven. But, you cannot leave these jars unattended when placed in a range. This is because the company does not mention all Oui jars as oven-safe. When they contain food, by its very nature, the food will be exposed to extreme temperatures during the cooking process. At that time, the temperature may get higher, creating a risky situation for the jars.

After being careful about such circumstances, you can use them for baking, storing, and serving food, just like a Mason jar. Just remember to keep the lid on while cooking so that the contents don’t spill. Once you’re done, you can also put the lid back on to store leftover food in your refrigerator. 

Oui jars are made of borosilicate glass, which is resistant to thermal shock and can also be used to make laboratory glassware. Since the borosilicate glass is also known as Pyrex and can be used in dry or wet applications, you shouldn’t find any issue when the temperature is set below the high heat setting.

You already know that the Oui jars are very durable, and you can safely use them in an oven, but remember that they are not meant for the oven. If your Oui jars have been purchased recently, you need to find the oven-safe marking at the bottom of the jar to confirm. 

When the Oui product doesn’t show oven-safe marking, you need to be careful when using that specific jar and keep the temperature below 200 degrees Fahrenheit. Cooking at a high temperature like over 300 degrees Fahrenheit will crack these Oui jars.

What Temperature Is Suitable For Baking Using The Oui Jars?

The Oui jars are safe for baking and cooking at any oven temperature when they come as oven-safe. We recommend using the Oui jars at temperatures up to 110 degrees Celsius or 230 degrees Fahrenheit. There is almost no risk of cracking if you use the Oui jars within this temperature limit. 

From the manufacturer’s instructions, the Oui jars have been specifically designed for use at 120 degrees Celsius or 248 degrees Fahrenheit. But we don’t recommend putting the pots at the highest-mentioned temperature. Some may not be able to absorb the highest possible heat.

The silicone sealant used in the Oui jar lids can withstand high heat and will not degrade or lose its function when used within the correct temperature parameters. Make sure your Oui jars are at room temperature before using them in the oven. If the temperature of your Oui jar is not balanced with the room temperature, you may need to adjust the temperature of your oven accordingly. 

For cold Oui jars, you need to rest them for some time and slowly increase the heat when placed inside the oven. On the other hand, you can use any temperature within the mentioned limit for hot Oui jars.

How Long Can You Bake In The Oui Jars?

You can bake with the Oui pots for as long as you like if the cooking temperature is below 200 degrees Fahrenheit. Because, this low temperature doesn’t affect any oui jar and keeps it at a stable temperature through constant heat. 

On the other hand, you can bake in oven-safe Oui jars for up to two hours at a temperature of up to 400 degrees Fahrenheit. We do advise you to check your product at 1 hour as every oven is different. But after testing it for up to 2 hours, everything has turned out fine.

Theoretically, how long you can bake in the Oui jars really depends on what you’re baking. For instance, if you’re baking a cake, you should be able to bake it for about 30 minutes without an issue. Since the cake doesn’t take much time for the baking process, keeping the Oui jars more than that can cause problems. 

On the contrary, when you are baking heavy and liquid foods, the cooking time can extend for a longer period. Because the heavy foods constantly absorb the cooking temperature to create balance with the Oui jars.

What Are The Uses Of Empty Oui Jars?

Empty Oui jars have a million uses! They’re great for storing everything from jewelry to makeup, craft supplies, and baby food. You can even use them as vases for your fresh flowers. To add more, empty Oui jars can be used for dry food storage, storing pastes and gels, or as a medium for growing small plants. If you are fond of planting, you can plant cuttings of herbs in the jars and transfer them to a larger pot when they’re ready to be transplanted outdoors.

Though you can use Oui jars for storing almost anything in your kitchen that fits the size, the most common use is to store pantry staples like pasta, grains and legumes. If you want more volume, then add more of each ingredient. If you want less volume, then use less of each ingredient. This is because the mixture of different ingredients creates gaps among the seeds. In every condition, you need to wash and dry your jars and lids before using them.

Frequently Asked Questions

Can I Put Oui Jars In The Dishwasher?

Oui jars are dishwasher safe according to the manufacturer, but we recommend hand-washing them. The reason for this is that the tapered neck of the jar can easily get damaged in the dishwasher. To avoid this issue, you can put them in a gentle cycle in the dishwasher. However, it’s always best to hand-wash all of your Oui jars. And, store your Oui jars in a cool, dry place.

Why Do Oui Jars Say Single Use Only?

We can’t say for sure why the jars say single use only. Oui products are made from medical grade silicon, and are safe to use more than once, but you’re not supposed to reuse the jars. The only reason can be here is that the product is made of glass and is not made to be repeatedly washed in a machine.

Final Speech

In the final analysis, it is clear that the Oui jars can be used in the oven when operated at a suitable temperature. According to the manufacturer, the Oui jars can be both oven-safe and not oven-safe. 

As a result, you won’t be able to use the same temperature as the oven-safe cookware for all Oui jars to get a safe baking process. If the product doesn’t show an oven-safe mark with it, you shouldn’t exceed the 200 degrees Fahrenheit limit for using it on an oven.
