Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
1 large onion, thinly sliced
1 cup shredded cheddar cheese
1/2 cup shredded mozzarella cheese
1 tbsp olive oil
1/2 tsp garlic powder
1/4 tsp black pepper
Salt to taste
Directions
I preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper.
I heat olive oil in a skillet over medium heat, then add the sliced onions and cook them until they’re caramelized, which usually takes about 10–15 minutes.
Once the onions are caramelized, I mix them in a bowl with cheddar cheese, mozzarella, garlic powder, black pepper, and a bit of salt.
I spoon small mounds of the mixture onto the prepared baking sheet, flattening them slightly.
Then I bake them for 8–10 minutes or until the edges are golden and crispy.
I let them cool for a few minutes before serving, so they firm up nicely.

Variations
When I want to change things up, I sometimes swap in different cheeses like pepper jack or gouda for a twist on flavor. Adding a sprinkle of red pepper flakes gives the crisps a spicy kick, while chopped herbs like rosemary or thyme offer a more aromatic profile. I’ve also tried adding a bit of grated parmesan for extra crunch, and it works beautifully.
Storage/Reheating
I store any leftovers in an airtight container at room temperature or in the fridge for up to 3 days. To reheat and bring back the crispiness, I pop them in a toaster oven or reheat them briefly in a hot oven for 2–3 minutes. I try to avoid microwaving, as it can make them soggy.
FAQs
What type of onion works best for this recipe?
I prefer using yellow onions because they caramelize beautifully and bring out a sweet, rich flavor that pairs well with cheese.

Definitely. With just about 2 grams of carbs per serving, these crisps fit perfectly into a low-carb or keto lifestyle.

I don’t recommend freezing them, as they can lose their crispiness and become chewy after thawing. Fresh or refrigerated is best.
