This parmesan onion ring chips recipe transforms simple onions into crispy, savory snacks that disappear from the table in minutes. The combination of sharp parmesan and sweet onions creates an irresistible appetizer that tastes indulgent but comes together with minimal effort.
I discovered this recipe when looking for a quick appetizer for game day, and it's become my secret weapon for impressing friends without spending hours in the kitchen. The combination of crispy cheese and sweet onions is absolutely addictive.
Ingredients
- Parmesan cheese: Shredded. The star ingredient that creates the crispy base and topping. Use freshly shredded for best melting results.
- White onion: Medium sized. Sweet when baked, providing the perfect contrast to the savory cheese. Look for firm onions without soft spots.
- Black pepper: Freshly ground if possible. Adds a subtle heat that enhances the savory flavors.
- Paprika: Adds a gentle smoky note and beautiful color. Regular works fine, but smoked paprika elevates this dish.
- Garlic powder: Infuses the chips with aromatic flavor without burning like fresh garlic might.
- Extra virgin olive oil: Or cooking spray. Just enough to help everything crisp up beautifully in the oven.
Step-by-Step Instructions
- Prep Your Baking Surface:
- Preheat your oven to 400°F and line a baking sheet with parchment paper. The parchment is crucial here as it prevents sticking and makes cleanup much easier. Make sure the paper lies flat without wrinkles for even cooking.
- Create Your Parmesan Base:
- Sprinkle half of your shredded parmesan evenly across the parchment paper, creating a thin layer that will become the crispy foundation of your chips. Try to distribute it as evenly as possible for consistent results.
- Layer Your Onions:
- Slice your onion into perfect 1/4 inch rounds, maintaining their circular shape. Carefully arrange these slices in a single layer on top of your parmesan base, ensuring they don't overlap which would prevent proper crisping.
- Season And Oil:
- Sprinkle the black pepper, paprika, and garlic powder evenly over each onion slice, then lightly spray or brush with olive oil. This thin coating of oil ensures everything becomes perfectly golden and crisp without becoming greasy.
- Add Final Cheese Layer And Bake:
- Distribute the remaining parmesan over the seasoned onion rings, covering them completely. Bake for 15 to 20 minutes, watching carefully toward the end as the difference between perfectly golden and too dark happens quickly.

Storage Tips
These parmesan onion ring chips can be stored in an airtight container in the refrigerator for 2-3 days, though they're best enjoyed fresh when they're at their crispiest. To restore some crispness after refrigeration, place them on a baking sheet and warm them in a 350°F oven for about 5 minutes. For longer storage, you can freeze them for up to 3 months in a freezer-safe bag with parchment between layers to prevent sticking.

Flavorful Variations
While the classic recipe is delicious on its own, you can easily customize these chips with different flavor profiles. Try adding Italian seasoning and a pinch of red pepper flakes for an Italian twist, or use smoked paprika and a touch of cumin for a smoky southwestern flavor. For herb lovers, adding finely chopped fresh rosemary or thyme to the cheese mixture creates an aromatic dimension that pairs beautifully with the sweet onions.
Serving Suggestions
These parmesan onion ring chips make a fantastic appetizer on their own, but they also shine as part of a larger spread. Serve them alongside a cool ranch or blue cheese dip for a delicious contrast. They also make an excellent garnish for creamy soups or as a gourmet topping for burgers and sandwiches. For a complete appetizer spread, pair them with olives, cured meats, and other finger foods for an impressive yet effortless presentation.
