If you’ve been seeing onion ring chips everywhere and wondering if they’re worth the hype, they are. You sprinkle shredded Parmesan on a sheet pan, top it with onion rings, bake until golden and crispy, then let them cool so they snap into crunchy, cheesy onion chips. No frying, no breading, and barely any prep. Just slice, bake, cool, and crunch. And if you’ve made my Viral Grillo’s Pickle Dip, you already know I'm always down for an easy snack that disappears fast.

Why You'll Love This Onion Chips Recipe
I’d seen videos of these onion ring chips for months and finally tried them, and yeah, I was missing out. If you loved Funyuns growing up like me, these hit that same salty onion craving, but even better because they’re real onion and real cheese. And this is a healthier low carb snack, too, with 20 grams of protein per serving!
The magic of these onion chips is how simple they are. Parmesan melts, then crisps into a lacy “chip,” while the onions caramelize and sweeten in the oven. You end up with the perfect salty-savory bite that feels like a snack hack, but it’s honestly just smart baking.
They’re perfect for snack boards, game day, parties, or any time you need something crunchy fast. Serve them with ranch, chipotle mayo, or your favorite dip, and they’ll be everyone's new favorite snack.
Onion Ring Chips Ingredients
- 2 small white onions, sliced into ¼-inch rounds
- 7 oz shredded Parmesan cheese
- ½ tablespoon olive oil
- Salt, garlic powder, paprika (to taste)
- Dipping sauce of choice
Ingredient Notes That Make These Onion Crisps Better
- Onions: White onions give the classic flavor and crisp nicely. Slice evenly so everything bakes at the same speed.
- Parmesan: Parmesan is the “chip.” Freshly grated Parmesan crisps best. Pre-shredded works, but some brands have anti-caking agents that can affect crispness.
- Parchment vs Silpat: Either works. If using parchment, a light spray helps prevent sticking.
- Seasoning: Keep it simple. Parmesan is salty, so go easy on salt until you taste a finished chip.
How to Make Onion Ring Chips
Step 1: Slice onions
Use a mandoline to slice onions into ¼-inch rings, keeping them intact as much as possible.
Step 2: Preheat and prep pan
Preheat oven to 400°F. Line a 12x17-inch rimmed baking sheet with parchment paper or a Silpat. If using parchment, lightly spray with pan spray.
Step 3: Add cheese layer
Sprinkle Parmesan in a thin, even layer across the baking sheet. Try not to leave big gaps.
Step 4: Add onion rings
Arrange onion rings on top of the cheese so they’re touching but not overlapping. Brush tops lightly with olive oil. Evenly season with salt, garlic powder, and paprika.
Step 5: Bake
Bake 18 to 25 minutes, until golden brown and crispy, like my photo below.
Step 6: Cool and break apart
Cool for 5 to 10 minutes, then break apart into chips and serve alone or with any dipping sauce you want.
Pro Tips for Crispy Onion Chips
- Slice the onions evenly. Even thickness will give you even crispness. If some rings are thick and some are thin, the thin ones can burn while the thick ones stay soft. A mandoline makes this easy, but a steady knife works too.
- Keep the Parmesan layer thin and even. Think “lacy cheese crisp,” not a thick pile of cheese. Too thick, and it stays greasy or chewy instead of snapping like a chip.
- Don’t overlap the onion rings. Overlapping traps steam and makes soft spots. Give each ring its own space so everything crisps up evenly. Either use a large baking sheet or bake in batches.
- Let them cool before you move them. Cooling is what turns them into chips. If you try to lift them hot, they’ll bend, tear, and stick. Give them a few minutes, then peel them off the tray cleanly.
- Go light on salt. Parmesan is already salty, so taste before adding much extra. If you want more seasoning, add it after baking (or dip in a salty sauce).
- Watch the last few minutes. They can go from perfectly golden to burnt fast, depending on your oven and the cheese you use. Start checking early and pull them when the edges are deep golden, and the cheese looks set.
- Use parchment for easiest release. Parchment helps prevent sticking and makes it way easier to lift the chips once they’re cool.

- Campfire sauce (smoky-sweet + spicy)
- Creamy jalapeño dip (cool, tangy, and addictive)
Onion Ring Chips FAQs
Why are my onion ring chips not crispy?
The most common reasons are a Parmesan layer that’s too thick, onion rings overlapping, or not letting them cool long enough. Keep the cheese in a thin, even layer, don’t overlap the onions, and let them cool completely so they snap into chips.
Can I use a different onion?
Yes. Yellow onions work great and caramelize nicely. Red onions are a little sweeter but can stay softer. White onions also work if you want a sharper onion bite.
Can I make these in an air fryer?
Yes, you can, it just takes smaller batches. Cut a piece of parchment to fit your air fryer basket, sprinkle a thin, even layer of shredded Parmesan (don’t mound it), then place onion rings on top in a single layer with space between them. Air fry at 375°F until the cheese is deep golden and the edges look set, usually about 6–10 minutes depending on your air fryer and how thick the cheese layer is. Let the chips cool for a few minutes before lifting them out, because cooling is what makes them crisp and lets them release cleanly. If you want to make a lot, the oven is still easier, but the air fryer works great for a quick small batch.
Do I need olive oil?
Not necessarily. A light brush can help browning and flavor, but you can skip it. Just watch the bake time closely because the chips may crisp a little faster without oil.
What cheese works best?
Parmesan gives the crispiest, chip-like result. Other cheeses melt more and can turn oily, so if you swap, expect a softer texture. A finely shredded Parmesan or a Parmesan blend usually works best.
Can I use pre-shredded Parmesan?
Yes, but freshly shredded Parmesan usually crisps better. Pre-shredded cheese can have anti-caking agents that affect melting and crisping. If you use pre-shredded, keep the layer thin and bake until deep golden.
How do you keep onion chips from sticking to the pan?
Use parchment paper and let the chips cool before lifting. Trying to remove them hot is when they stick and tear. Once cooled, they peel off much easier.
Can I store leftover onion chips?
They’re best fresh, but you can store them in an airtight container at room temperature for up to 1 day. If they soften, re-crisp in the oven at 350°F for a few minutes.
