Equipment
- Oven
- Baking sheet
- Parchment paper
- Cutting board
- Sharp knife
- Measuring cups and spoons
Ingredients
- 2 large white onions, sliced into ¼-inch rings
- 2 cups shredded Parmesan cheese
- ½ teaspoon salt (or to taste)
- ½ teaspoon garlic powder
- ¼ teaspoon paprika
- Optional: Italian seasoning to taste
Instructions
- Preheat your oven to 400°F and line a baking sheet with parchment paper.
- Separate the onion slices into individual rings and pat them dry with a paper towel.
- For each onion ring, sprinkle about 1 tablespoon of shredded Parmesan onto the prepared baking sheet to form a small cheese “nest.”
- Place one onion ring on top of each cheese mound. Then add another tablespoon of Parmesan on top of the onion ring and press gently so the cheese sticks.
- Sprinkle a bit of salt, garlic powder, paprika, and optional Italian seasoning over each prepared ring.
- Bake in the preheated oven for approximately 15–20 minutes, or until the cheese edges are golden and crispy.
- Allow the onion rings to cool on the baking sheet for 10–15 minutes so they set up and crisp further before serving.

How to Store
- Store leftover onion rings in an airtight container in the refrigerator for up to 3 days.
- To maintain crispiness, reheat in an oven or air fryer at moderate heat until warmed through.
- Do not store with damp toppings or sauces, as moisture can make them lose crunch.
What Not to Do
- Do not skip the parchment paper—cheese will stick and make cleanup difficult.
- Avoid overcrowding the baking sheet; rings need space to crisp evenly.
- Don’t serve them immediately hot from the oven without cooling; they will be soft until they set.
Tips & Variations
- For extra flavor, mix some grated cheddar or asiago with the Parmesan.
- Add a pinch of cayenne or chili flakes for a spicy kick.
- Try air-frying instead of baking for even quicker crispiness.
- Serve with low-carb dips like garlic aioli, ranch, or spicy mayo.

The base is mild; you can add spices like cayenne if you want more heat. - Can I air fry instead of bake?
Yes—air fryer versions can crisp faster. - Why didn’t mine crisp?

Keto ranch, garlic aioli, or spicy mayo are great pairings.
