- 5 ounces shredded Parmesan cheese: Adds a rich, savory layer that crisps into a golden, cheesy crust.
- 1 tablespoon olive oil: Helps the onions brown and keeps the chips perfectly tender yet crispy.
- 1/2 teaspoon sea salt: Enhances the natural flavors and balances the savory elements.
- 1/2 teaspoon garlic powder: Brings a warm, mellow garlic flavor without overpowering the dish.

How to Make Oven-Baked Parmesan Onion Ring Chips Recipe
Step 1: Prepare the Onions
Start by preheating your oven to 400 degrees Fahrenheit to get it properly hot and ready for crisping. Thinly slice your yellow onions using a mandolin or a very sharp knife—aim for delicate, even slices about 1/28th of an inch thick. This thickness ensures the chips will bake evenly and turn that perfect shade of golden crisp.
Step 2: Create the Parmesan Base
Line a baking sheet with parchment paper, then spread your shredded Parmesan cheese into a thin, even layer that covers the entire surface. This layer will serve as a deliciously crispy foundation for your onion slices and prevent sticking.
Step 3: Layer the Onion Slices
Arrange the thin onion rings carefully over the Parmesan layer in a single, even layer. Make sure the slices don’t overlap too much so that every chip crisps up beautifully on all sides.
Step 4: Season and Oil the Onions
Brush the onion slices gently with the olive oil. Then sprinkle the sea salt, garlic powder, smoked paprika, and black pepper evenly over the top. This combination of seasonings adds vibrant color and a burst of savory flavor that’s irresistible.
Step 5: Bake Until Crispy
Pop the baking sheet into your preheated oven and bake for 18 to 20 minutes. Keep an eye on the chips as they bake; you want the cheese to turn golden and crisp while the onions soften and become crunchy, but not burnt.
Step 6: Cool and Slice
Once baked to perfection, take the chips out of the oven and let them cool for a few minutes on the baking sheet. This cooling step allows the Parmesan to set fully, making those chips easy to cut and enjoy without falling apart. Slice them into individual chips or small clusters, and get ready to indulge.
How to Serve Oven-Baked Parmesan Onion Ring Chips Recipe

Garnishes
These chips are amazing on their own, but you can take presentation up a notch by sprinkling a little extra Parmesan or freshly chopped herbs like parsley or chives. A tiny drizzle of truffle oil over the top adds a gourmet touch that pairs beautifully with the smoky paprika.
Side Dishes
Oven-Baked Parmesan Onion Ring Chips Recipe complements lots of homemade dips and spreads — try them with garlic aioli, spicy sriracha mayo, or a cool tzatziki for contrast. They’re also a great crunchy side next to juicy burgers, grilled chicken, or a fresh salad.
Creative Ways to Present
Serve these chips in small snack bowls for easy sharing at parties, or layer them atop salads for a fun texture contrast. You could even crumble them over soups as a crispy garnish, adding a savory crunch that transforms the dish entirely.
Make Ahead and Storage
Storing Leftovers
If you have leftovers of the Oven-Baked Parmesan Onion Ring Chips Recipe, store them in an airtight container at room temperature. This will keep them slightly crisp for up to 2 days. Avoid refrigeration, which can make them soggy.
Freezing
While these chips taste best fresh, you can freeze leftovers by placing them in a single layer in a freezer-safe bag. When ready to enjoy again, thaw briefly at room temperature and re-crisp in a 350°F oven for a few minutes.
Reheating
To bring back that just-baked crunch, pop your stored chips into a preheated oven at 350 degrees Fahrenheit for 3 to 5 minutes. Keep an eye on them so they don’t burn. Avoid microwaving as it softens the cheesy crispness.
FAQs
Can I use other types of onions for this recipe?
Absolutely! While yellow onions provide a nice balance of sweetness and sharpness, you can experiment with white or red onions for a different flavor profile. Just make sure to slice them thinly for the best crisp.
Is this recipe gluten-free?

How crispy do these chips get compared to fried onion rings?
These chips bake up wonderfully crispy thanks to the Parmesan base and thin onion slices. While they won’t have the exact crunch of deep-fried onion rings, their lighter texture and cheesy coating make them just as satisfying in a healthier way.
Can I add other seasonings to this recipe?
Of course! Feel free to personalize the seasoning with your favorites, such as cayenne pepper for heat, Italian herbs for freshness, or even a pinch of cumin for earthiness. The Oven-Baked Parmesan Onion Ring Chips Recipe is really adaptable to your taste.
