Gather Your Ingredients
- White onions: sliced into rings the star of the show offers natural sweetness and gentle bite Always pick onions that feel firm without soft spots
- Shredded parmesan cheese: gives the crust its crunch and salty depth Use a block and grate it yourself for best melting and flavor
- Salt: brings out all the flavors and balances the cheese
- Garlic powder: adds savory warmth
- Paprika: for color and a gentle kick Use smoked if you like a little extra flavor
- Italian seasoning: an herby touch and complements the onion and cheese Choose blends with oregano and thyme for best results
How to Make It
- Preheat Your Oven:
- Bring your oven to 400 degrees Fahrenheit which creates high heat for crispness and prevents sogginess Prepare a large baking sheet with parchment paper so the cheese does not stick
- Build the Cheese Base:
- Sprinkle about one tablespoon of shredded parmesan on the parchment to form a small circle Do this for each onion ring you want to bake These will melt and crisp becoming the bottom layer
- Position the Onion:
- Take a sliced onion ring and set it directly on top of each parmesan round Try to choose rings that are even and not broken for best presentation
- Layer More Cheese:
- Add another tablespoon of parmesan cheese over each onion ring Spread it evenly to completely cover the onion as this acts as both coating and glue
- Flatten and Secure:
- Use the back of a spoon to press everything together slightly This step ensures the cheese will bake into a cohesive crunch around the onion
- Season Generously:
- Sprinkle salt garlic powder paprika and Italian seasoning over the top of each cheese covered onion ring Adjust the amounts to your taste—extra paprika for more color extra garlic for punch
- Bake to Perfection:
- Slide the tray into your preheated oven Bake for 15 to 20 minutes but watch closely after 15 The cheese should melt bubble then turn deep golden and crisp at the edges Let cool a few minutes before moving so they firm up
