Second Time’s the Charm: Can You Reheat Onion Rings and Still Enjoy their Crispiness?

Onion rings are a beloved side dish, but what happens when you have leftovers? Can you reheat onion rings and still enjoy their crispiness and flavor? Let’s take a closer look.

The Science of Reheating

When food is reheated, the moisture that was present in the food when it was cooked evaporates. This can cause the food to become dry and lose its texture.

This is especially true for fried foods like onion rings, which rely on a crispy coating to maintain their texture.

The Microwave

When reheating onion rings in the microwave, the radiant heat causes the coating to absorb moisture from the air. This can make the coating soggy and lose its crispiness. The high heat of the microwave can also cause the coating to become tough and chewy, rather than crispy.

Another issue with reheating onion rings in the microwave is that it can cause the oils used for frying to separate from the coating. This can give the onion rings an unappealing greasy texture and taste.

It is important to note that if you must reheat onion rings in the microwave, you should use a microwave-safe plate or dish and cover it with a microwave-safe lid or a damp paper towel to trap some of the moisture.

Also, it is better to reheat them for short intervals of time and check on them frequently to ensure they don’t become too soggy.

While the microwave may be a convenient option for reheating food, it’s not the best choice for reheating onion rings. The radiant heat of the microwave can cause the coating to become soggy, making the onion rings lose their crispiness and texture. It’s better to reheat them in the oven or fry them again to maintain their crispiness.

The Oven

Reheating onion rings in the oven can help to maintain their texture and crispiness. The oven uses convection heat, which circulates hot air around the food. This can help to evaporate the moisture from the food, keeping it crispy.

To reheat onion rings in the oven, preheat the oven to 350 degrees Fahrenheit, and place the onion rings on a baking sheet. Heat them for 8-10 minutes, or until they are heated through and crispy.

The Frying

Another way to reheat onion rings and keep their crispiness is to fry them again. This method will give the onion rings that crispy texture that everyone loves, but it will also add more oil to the food, which may affect the taste and healthiness of the dish.

The Taste

Frying onion rings again is a surefire way to regain their crispiness, however, it also adds more oil to the dish which can affect the taste and healthiness of the food.

When you fry food, the oil is absorbed into the food, which can change the taste and texture of the food. Additionally, the added oil can make the food less healthy. The extra oil can also add more calories to the dish, which may not be ideal for those watching their calorie intake.

Another downside to this method is that it may cause the oil to become too hot, leading to over-frying, which can also affect the taste of the food. This can also cause the coating to become dark and burnt, which can make the onion rings unappetizing.

While frying onion rings again is a great way to regain their crispiness, it’s important to consider the added oil and potential health concerns. It’s best to use this method in moderation and combine it with other reheating methods such as using the oven. Additionally, you may want to use healthier oils for frying such as avocado oil or coconut oil which have healthier properties.


Reheating onion rings can be tricky, but it is possible to maintain their crispiness and taste. The oven is the best option for reheating, as it uses convection heat to circulate hot air around the food, keeping it crispy.

Frying the onion rings again can also maintain the crispiness, but it will also add more oil to the food. Microwaving the onion rings is not recommended as it can make the coating of the onion rings soggy.
