Microwave Reheating

Microwaving onion rings is the fastest and the least favorite reheating method because microwaving makes fried foods quite soggy. However, lining the plate with paper toweling will help absorb the grease and reduce sogginess.

Place the onion rings single file on top of two or three paper towel layers on a microwave-safe plate, and set the onion rings single layer on the paper toweling. Next, microwave at 20-second intervals at high temperatures until the onion rings are thoroughly heated.

Remove the plate from the microwave and add extra salt or other seasonings and serve.

Oven Reheating

For the best results, allow the onion rings about an hour to warm up to room temperature and preheat the oven to 350 f degrees. Cover the baking sheet with parchment paper, place the onion rings single file, and cover the baking tray with aluminum foil.

Place the baking sheet on the middle rack and bake for about ten minutes or until the onion rings are heated completely.

Can you Freeze Cooked Onion Rings?

According to the National Center for Food Preservation, freezing onion rings is a safe method to preserve your onion rings for later usage. Moreover, there are food safety precautions to follow to ensure that your frozen onion rings will be safe for consumption.

To begin, peel, wash and chop the onions into slices. Next, blanch the raw onion rings for 10 to 15 seconds in boiling water. Remove the onions from the boiling water with a slotted spoon and place those in a colander to cool and drain.

Please be sure to check that the onions are completely cool before moving to the next step. Then, dip the raw onions into cold milk, and coat the rings with a breading of your choice. Next, place the breaded onion rings single file onto a clean baking sheet or tray.

Freeze the onion rings separated on the sheet to avoid the onion rings freezing in clumps. Once the rings are fully frozen, pack those into a Ziploc container or bag with saran wrap protecting the layers of onion rings from sticking to each other and seal the bag.

Please note that the onion rings will keep in the freezer for ten months to one year. It is not advisable to consume any onion rings past one year of storage in the freezer.

Next, line a baking sheet with parchments paper and place your cooked onion rings single file onto the baking sheet. Set the sheet in the oven to keep the onion rings crispy and warm until you are ready to serve dinner.
