Crispy Parmesan Onion Crisps Recipe
Introduction
If you crave a snack that delivers a satisfying crunch with an explosion of savory, cheesy flavor, these Crispy Parmesan Onion Crisps will be your new go-to. Whether served as a crowd-pleasing appetizer or a tasty topping for salads and burgers, these crisps marry the sweetness of onions with the irresistible umami punch of Parmesan cheese, all baked to a golden crisp.
The beauty of this recipe lies in its simplicity: minimal ingredients, quick preparation, and a result that will have everyone reaching for seconds.
What Makes Crispy Parmesan Onion Crisps a Must-Try Snack
The magic here is the contrast — thinly sliced onions roast up sweet and tender under a blanket of sharp Parmesan. The edges turn lacy and golden, each bite melting on your tongue with a delicate crunch. These crisps are packed with flavor, gluten-free, and baked (not fried), making them a smarter choice for guilt-free snacking.
You can enjoy them on their own, crumble over soups, or layer into sandwiches for extra pop and texture.
How to Slice Your Onions for Perfect Crisps
The key to irresistibly crunchy crisps is evenly thin onion slices. Using a mandoline or specialty vegetable chopper guarantees consistent, wafer-thin rounds that cook uniformly and crisp up beautifully. Try the Mueller Pro-Series 10-in-1, 8 Blade Vegetable Chopper for quick, safe slicing.
Cutting boards are essential for tidy prep—consider a sturdy set like Bamboo Cutting Boards for Kitchen, Set of 3 to streamline your kitchen workflow.
Getting Crispy Results: Baking vs. Air Frying
Achieve a perfectly golden crunch in your oven or air fryer—both methods work beautifully. For oven baking, line your sheet with a piece of Reynolds Kitchens Brown Parchment Paper Roll for effortless removal and easy cleanup. If you have an air fryer, the COSORI Air Fryer 9-in-1, Compact & Large 6-Qt helps speed up cooking and delivers ultra-crisp edges with minimal oil.
For either method, a light mist of oil is key. Get even coverage without excess using an YARRAMATE 16oz/470ml Oil Sprayer for Cooking, Black for healthier, crispier results.

- Peel and slice onions into thin, even rounds (about ⅛-inch thick). For best results, use a Mueller Pro-Series 10-in-1, 8 Blade Vegetable Chopper to get consistent slices.
- Preheat your oven to 400°F (or air fryer to 375°F). Line a baking sheet with Reynolds Kitchens Brown Parchment Paper Roll for nonstick, easy cleanup.
- Separate the onion slices into rings. In a large bowl, gently toss rings with olive oil (or use the YARRAMATE 16oz/470ml Oil Sprayer for Cooking, Black for an even coat).
- Arrange onion rings in a single layer on the prepared baking sheet or air fryer basket. Sprinkle generously with Parmesan, black pepper, garlic powder, and optional spices.
- Bake for 15–20 minutes, flipping halfway, or air fry for 8–12 minutes. Watch closely the last few minutes—they should be golden and crisp, not burnt.
- Let crisps cool slightly to firm up. They’ll continue to crisp as they cool.
- Serve warm or store in an airtight container for up to 3 days.
