How do you get perfectly sliced onions?

The key to consistently thin, even slices is using a mandoline slicer . It allows you to adjust the thickness and ensures that every ring is uniform—essential for even cooking and crisping. If you don’t have one, a sharp chef’s knife can work too, but be extra careful to maintain a steady hand and consistent width (aim for about ¼ inch). Perfectly sliced onions make your onion rings chips cook evenly and hold their shape better in the oven or air fryer.

What kind of onions should I use?

Sweet onions are the top choice for onion rings chips because they balance beautifully with the salty parmesan. They caramelize lightly while baking, adding a mild sweetness that elevates the flavor. That said, yellow onions also work great if you want a more traditional, savory taste. For bolder flavors, try white onions or red onions , but note they’ll bring a stronger bite.

Can I cook this in my air fryer?

Absolutely! In fact, the air fryer gives you extra crispiness and quicker results. Preheat it to 375°F , place your cheese and onion rings on parchment paper (cut to fit), and cook for 6–9 minutes . Every air fryer model is a little different, so start checking for doneness around minute 6. This is a great method for small batches and quick snacks.

How do I store the leftovers?

Once your onion ring chips have cooled down fully, tuck them into an airtight container with a paper towel at the bottom to soak up any lingering moisture. This trick helps preserve their crunch. Pop the container in the fridge and enjoy within 3 days. Just be sure the rings are totally dry before storing to avoid sogginess.

How do I reheat these?

The best way to bring back the crisp is by reheating in the oven or air fryer . Set your oven to 350°F or your air fryer to 360°F , and heat the chips for 3–5 minutes . This helps the cheese firm up again and restores that signature crunch. Avoid using the microwave—it’ll make them chewy or rubbery.

Instructions

Preheat the oven: Set your oven to 400°F and line a baking sheet with parchment paper.
Prepare the base: On the parchment paper, create small cheese mounds about the size of each onion slice.
Add onion rings: Place an onion slice over each cheese mound and gently press down so they stick together.
Season and oil: Lightly mist each ring with cooking spray or brush with olive oil. Sprinkle with garlic powder, smoked paprika, and black pepper.
