Crispy Sheet Pan Onion Rings: Easy Recipe for Crunchy Snacks

These crispy sheet pan onion rings are one of those recipes where you look at the ingredient list and wonder how something this simple is going to work. Onion, bacon, and a couple cheeses - that's pretty much it.

But once everything hits the oven, the cheese gets golden and crispy, the bacon adds a ton of flavor, and the onion softens just enough. You end up with these crispy, cheesy onion rings that are ridiculously easy to make.

Why You'll Love These Crispy Sheet Pan Onion Rings

The biggest reason I like these is there's no breading and no frying. Traditional onion rings are great, but they're also a whole production. These aren't.

You can have everything on the sheet pan in a few minutes, throw them in the oven, and about 10 minutes later they're ready. They work as an appetizer, snack, or an easy side when you're making burgers or something on the grill.

And bacon and Parmesan cheese are involved, so we're already starting from a pretty good place.

What You'll Need

You only need three ingredients for these crispy sheet pan onion rings - a large onion, shredded Parmesan cheese, and cooked bacon.

I like to cook the bacon until it's nice and crispy before chopping it up. You're only baking these for about 10 minutes, so you don't want to rely on the oven to finish cooking the bacon.

For the onion, slice it into fairly thick rings. If you go too thin, the onion can get lost underneath all that crispy cheese and bacon.

How To Make Crispy Sheet Pan Onion Rings

Start by preheating your oven to 400°F and lining a baking sheet with parchment paper. The parchment is important here because once that Parmesan melts and crisps up, you want the onion rings to release easily.

Add a small pile of chopped bacon to the baking sheet, roughly the same size as one of your onion slices. Sprinkle some Parmesan cheese over the bacon, then place an onion ring directly on top.

Finish each one with another little layer of Parmesan cheese. Repeat until you've used all of your onion rings.

Bake everything for about 10-12 minutes. You're looking for the Parmesan around the outside to be melted, golden brown, and crispy.

Let Them Cool Before You Move Them

This part actually makes a difference. When the crispy sheet pan onion rings first come out of the oven, the cheese will still be pretty soft.

Give them about 10 minutes right on the baking sheet. As the Parmesan cools, it firms up and gets much crispier. Then you can lift them right off the parchment and serve.

What To Serve With Them

I could easily eat these straight off the sheet pan, but they're also really good with ranch, spicy ranch, or your favorite dipping sauce.

They're an easy side for burgers, grilled chicken, steak, or pretty much anything you're already cooking outside. You could also make a couple of trays and serve them as an appetizer for game day.

Tips For The Best Sheet Pan Onion Rings

Don't pile the bacon and cheese too thick. You want enough to create that crispy base, but if you overload them, you'll end up with a big puddle of cheese instead of individual onion rings.

I'd also keep an eye on them toward the end. Parmesan can go from perfectly golden to too dark pretty quickly. Once those edges are browned and crispy, they're ready to come out.

These crispy sheet pan onion rings are about as easy as an appetizer gets. Three ingredients, one sheet pan, and no messing around with breading or a pot of hot oil. That's a win for me.
