If you love onion rings, you are going to love these low-carb onion ring chips, which require only two ingredients. They are crunchy, tasty, easy to make, and perfect as a snack or appetizer.

This Viral onion ring chips recipe is taking social media by storm and I had to give it a try myself. The kids were even more excited to try these so I made it and it is worth all the hype. I highly recommend that you give it a go since you can technically make it with only two ingredients. Onions and shredded parmesan cheese. You can get store-bought parmesan cheese or shred your own. I do recommend adding the seasonings to add in more flavor. So good!
Ingredients needed
Below is a list of ingredients you will need to make them. Full measurements are listed further down below in the recipe card.
- Onions, peeled and sliced to 1/4 inch thickness: Depending on the size of onions you use, you may need 2-3 onions.
- 8 ounces shredded parmesan Cheese
- Seasonings I used: onion powder, garlic powder, and smoked paprika
- Cooking oil spray or any oil of choice.
- Optional dips: Tzatziki, Ranch, or ketchup
How to make Onion Ring Chips
Below is a step-by-step visual to show you how to make it. Full instructions also found in the recipe card.
- Preheat the oven to 400F and line a sheet pan with Parchment paper.
- Using a Mandolin slicer, slice the onions thin (1/4 inch thickness)
- Spread the shredded parmesan cheese over the prepared sheetpan.
- Carefully line the sliced onions over the parmesan cheese.
- Spray with cooking oil spray and season with the paprika, onion powder, and garlic powder.
- Bake for 18-20 minutes or until the cheese turns golden brown.
- Allow it to cool for 10 minutes so the cheese hardens up.
- Cut them into squares and serve with your favorite dip.
Tips from my kitchen
- Don’t cut the onions too thick or they will just be soggy or not cooked enough by the time the cheese turns golden brown.
- This recipe does only need the 2 ingredients but adding seasonings is a bonus.
- If you do not have a mandolin slicer using a sharp knife and cut as thin as possible.
- Don’t forget to use parchment paper.
- Allow it to cool! This hardens up the cheese and gives you that crispy crunch.
- What I found helpful is placing a cutting board over the pan and flipping it to the other side so you can easily peel the parchment paper off and cut them on the cutting board.
Common Questions
I recommend using either sweet white onions or yellow onions.
Yes. Shredding your own parmesan cheese is even better.
Absolutely. Add in any seasonings you prefer. It doesn’t have to be the ones I used.
If you have leftovers, you can store them in the fridge for up to 2 days. They will lose their crunch. I saved a few on my counter covered on a plate for one of my kids for about 3 hours, but they lost their crunch. Just fyi. Maybe leave them uncovered if you plan to eat them within a few hours. I do not recommend freezing.
