Why You’ll Love These Parmesan Onion Rings

Crispy without frying – Parmesan works like magic, creating that satisfying crunch in the oven.
Viral for a reason – They’re just as addictive as TikTok promised.
Quick & easy – You’ll be snacking in about 30 minutes from start to finish.
Customizable – Spice them up or keep them mild—your call.

Ingredients You’ll Need

Onions – Firm, fresh white onions give the best mild-sweet flavor. Slice into even ¼-inch rings (mandoline slicer fans, this is your time to shine—but please use the guard or a glove).
Parmesan cheese – Freshly shredded melts and crisps beautifully, but pre-shredded is fine if you’re in a hurry. Just skip the powdery kind.
Olive oil (optional) – For extra browning and richness.
Seasonings – Salt, garlic powder, paprika. Add chili powder or flakes if you like a kick.

How To Make Viral Parmesan Onion Rings

Preheat & prep
Set your oven to 400°F and line a baking sheet with parchment paper. This step is crucial—the parchment keeps the parmesan from welding itself to your pan and ensures that satisfying, lacy cheese crust. Avoid foil or wax paper—they’ll sabotage your crisp factor.
Slice those onions
Peel your onions and cut them into ¼-inch rounds. Aim for slices that are consistent in thickness—this helps every ring cook evenly so you don’t have a mix of overdone and underdone pieces. If you’re using a mandoline slicer, remember: safety first! Use the guard or a cut-resistant glove.
Lay down the cheese base
On your parchment-lined tray, place about 1 tablespoon of shredded parmesan for each onion ring you plan to make. Gently flatten it into a circle just a smidge larger than your onion ring. This will form that crispy, golden “halo” of cheese that makes these so irresistible.
Place the onion ring
Nestle one onion ring right in the middle of each cheese circle. Press lightly so it settles in—think of it as tucking it into a cheesy bed.
More cheese, please
Sprinkle another heaping tablespoon of parmesan over the top of each onion ring, fully covering it. Use the back of a spoon to gently press it down so the cheese bonds with the onion. This double layer means extra crunch on both sides.
Season like you mean it
Sprinkle each ring with salt, garlic powder, and paprika. These seasonings don’t just add flavor—they help deepen the color so you get that appetizing golden-brown finish. If you’re in the mood for spice, add a pinch of chili flakes or cayenne.
Bake to golden perfection
Slide your tray into the oven and bake for 15–20 minutes. Keep an eye on them in the last few minutes—parmesan can go from perfect to “call the smoke alarm” in a flash. You’re looking for deep golden edges, bubbly cheese, and that savory aroma that will have everyone wandering into the kitchen asking, “Is it ready yet?”
Cool for crunch
This is the hardest part—waiting. Let your onion rings cool on the tray for 10–15 minutes. This allows the cheese to firm up so you can lift them easily without breaking, and it actually makes them even crispier.

Mounia’s Tips for the Best Results

Don’t skip the parchment – Foil or wax paper just won’t cut it.
Fresh parmesan = better melt – But pre-shredded will still taste great.
Cool before serving – They crisp up more as they cool.
Pair them up – They’re amazing with marinara, ranch, or a spicy aioli.

FAQs About Parmesan Onion Rings

Can I make these in the air fryer?

Absolutely! Just place them on parchment cut to fit your basket, and air fry at 375°F for about 8–10 minutes, checking for golden edges.

How do I store leftovers?

Pop them in an airtight container in the fridge for up to 3 days. Re-crisp in the oven or air fryer before eating.

Can I use other cheeses?

Yes, but hard cheeses like asiago or romano give the best crunch. Softer cheeses will melt but not crisp as much.

Bringing It All Together

These Parmesan Onion Rings aren’t just a trend—they’re a keeper. Minimal ingredients, maximum flavor, and no deep fryer required. Once you try them, you’ll understand why TikTok fell in love. So grab a couple of onions, shred that cheese, and let your oven work its magic.

Because sometimes, the best recipes are the ones that make you wonder why you ever did it any other way.
