Crispy 2-Ingredient Onion Ring Chips

Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

1 large sweet onion

1 cup finely shredded parmesan cheese

Directions

I start by preheating my oven to 400°F (200°C). I line a large baking sheet with parchment paper to prevent sticking and make cleanup easier.

I peel the onion and slice it into thin rings, about ⅛-inch thick. I gently separate the rings and set them aside.

Next, I place small mounds of shredded parmesan cheese, about 1 tablespoon each, onto the prepared baking sheet. I make sure to space them about 2 inches apart so they have room to spread.

I gently press an onion ring into the center of each cheese mound. I lightly flatten it so the cheese spreads slightly around the onion.

I bake them for 12 to 15 minutes, until the cheese is melted, bubbling, and golden brown around the edges.

Once baked, I remove the tray from the oven and let the chips cool on the baking sheet for 5 to 10 minutes. I find that they crisp up beautifully as they cool.

Finally, I carefully lift them from the parchment paper and serve them immediately while they’re at their crispiest.

Variations

I sometimes switch things up by adding a light sprinkle of garlic powder or Italian seasoning over the cheese before baking. When I want a little heat, I add a pinch of red pepper flakes.

I also like experimenting with different cheeses. I have tried mixing parmesan with a bit of shredded mozzarella for a slightly softer center, though I keep parmesan as the base for maximum crispiness.

If I want a stronger flavor, I use sharp aged parmesan. For a milder taste, I choose a younger parmesan or even a blend of hard cheeses.

Storage/Reheating

I store any leftovers in an airtight container in the refrigerator for up to 3 days. To keep them from getting soggy, I place a paper towel in the container to absorb excess moisture.

When I reheat them, I avoid the microwave because it makes them soft. Instead, I place them in a preheated oven at 375°F (190°C) for about 5 minutes or until they crisp up again. I can also reheat them in an air fryer for a few minutes to bring back their crunch.

FAQs

Can I use a different type of onion?

I can use yellow or white onions, but I prefer sweet onions because I find their flavor balances the saltiness of the parmesan beautifully.

How do I keep the chips from sticking?

I always use parchment paper and allow the chips to cool before removing them. I find that they release much more easily once they have crisped up.

Can I make these in an air fryer?

I can make them in an air fryer by placing the cheese mounds on parchment paper designed for air fryers. I cook them at around 375°F until golden and crisp, keeping a close eye to prevent burning.

Why aren’t my chips crispy?

If my chips turn out soft, I check whether I sliced the onions too thick or didn’t bake them long enough. I also make sure I let them cool fully, since they crisp up as they rest.

Are these suitable for a keto diet?

Yes, I find these perfect for a keto or low carb lifestyle because they are made with just onion and parmesan cheese, with no flour or breadcrumbs added.

Conclusion

I love how something so simple can turn into such a satisfying snack. These crispy 2-ingredient onion ring chips give me all the crunch and savory flavor I crave without complicated steps or extra ingredients. Whenever I need a quick appetizer or low carb snack, this is one of the first recipes I reach for.
