About Baked Onion Rings

Onion rings are one of those perfect-for-any-occasion foods, from casual finger food to a garnish on a steak, and this recipe has quickly become my favorite version of this finger food classic.

Not only are they baked (so no messy oil) but they’re also coated in a crunchy cornflake breading (no flour used). This gives these baked onion rings all crispiness of their deep-fried cousins without the oily, floury mess left behind.

Are baked onion rings healthier than fried onion rings?

If onion rings are what you’re craving, then yes, baking onion rings in the oven is a better-for-you choice than eating onion rings that have been deep fried.

To put in the simplest terms possible, deep frying foods not only leaves a residue of oil on your food but it also causes chemical reactions that contribute to all sorts of health conditions (such as heart disease, diabetes, etc).  If you’d like to read more about the science behind it, check out this article: Facts on Why Baking Foods is Better Than Deep Frying Foods.

Plus, when you bake instead of fry, you don’t need to worry/store/waste a bunch of oil for just a simple meal. And I don’t know about you, but I’ll gladly clean a baking sheet before wrangling the messy aftermath of an oil frying adventure.

What temperature do you bake onion rings at?

How long are baked onion rings good for?

Can you freeze onion rings?

Yes, you totally can!

Once prepared and cooled, baked onion rings can be stored in a sealed container or freezer bag for up to two months.

How do you reheat baked onion rings?

Reheating these tasty bites is simple! Just follow these steps:

  • If you haven’t already done so, make sure the onion rings have thawed before reheating.
  • Preheat oven to 350 degrees F. Line a baking sheet with aluminum foil.
  • Arrange onion rings in a single layer on the baking sheet.
  • Cook for 3-5 minutes or until onion rings are crunchy again.

How do you bake onion rings?

This next part is only a photo tutorial of the recipe steps. If you’re looking for the full recipe measurements and instructions, scroll down to Recipe Details.

Step 1 – In a large bowl, add crushed cornflakes, sugar, paprika, accent salt, and garlic salt. Use a whisk or fork to thoroughly mix all of the ingredients together. Once mixed, set the bowl nearby.

Step 2 – In a small, wide bowl, add the two eggs and whip them until thoroughly beaten. Set this bowl beside the one with the breading mix.

Step 3 – Take a sliced onion and dip it in the beaten egg. I like to use a fork to flip the onion a few times, making sure all sides are coated.

Step 4 – Transfer the egg-coated onion to the bowl of breading mix, then toss to coat. Just like with the egg, I like to use a fork to flip the onion and toss the breading on the inside and outside of the onion ring.

Step 5 – Arrange the onion rings on a baking sheet lined with aluminum foil.

Step 6 – Repeat until all the onion rings are coated, then bake.

Step 7 – Serve and enjoy!

Yields: 24 onion rings
These baked onion rings are coated in a seasoned cornflake breading (no flour!) and cooked in the oven until tender on the inside and crisp on the outside.

Ingredients 

Instructions

  • Preheat oven to 375 degrees F. Line two large baking sheets with aluminum foil, then set aside.
  • Cut onions into 1/2 inch thick slices. Discard the small, inside rings and inner parts of the onion. For good presentation, use only the onion slices that are at least 2 inches in diameter. Once cut and separated, set onion nearby.
  • In a large bowl, add crushed cornflakes, sugar, paprika, accent salt, and garlic salt, then whisk to mix. Set nearby.
  • In a small wide bowl, add the two eggs and whisk well. Set nearby.
  • To prepare onions: Dip an onion ring in the egg mixture and use a fork to flip it a few times to coat. Transfer egg-coated onion to the dry ingredients, using a new fork to flip the onion over again, pushing the bread crumbs on the onion so that they stick. Once onion is completely coated, place on prepared baking sheet. Repeat this step until all of the onion rings are coated.
  • Bake onion rings for 15-20 minutes or until breading is crispy and lightly browned.
  • Serve immediately.

    I cannot wait to make these onion rings. We love onion rings but never eat fast food so will have to definitely try this recipe!

    Great recipe !!!

    • Kayla

    Can you use bread crumbs instead of cornflakes?

      • Ashley

      Wondering the same…

    No disrespect but no one wants to hear 5 star “opinions” for recipes that they’re “going to make”. We want ratings from those of whom actually MADE the recipe!

    This looks great! I’ve been looking for a side to go with pulled pork, and these look perfect!

    I would suggest, for reheating, use a pizza stone – tends to be better than foil lined pans for reheating crunchy foods.

    I absolutely loved this idea!! Thank you so much !! The only hitch is we are vegans. Can I use a substitute for eggs? If so, what would it be?

    Loving this Chrisy! Onion rings are one of our favorites but we usually don’t order them because they’r deep fried, so this baked version made with cornflakes (That’s genius!) is going to happen very soon!
