Can I use a different type of onion?

Yes! Yellow, white, sweet, or even red onions will all work. Sweet onions tend to have the mildest, most pleasant flavor, but it's really a matter of personal preference.

What if I don't have an air fryer?

No problem! The oven method works just as well. The chips may take a few minutes longer to cook, but the results are equally delicious.

Are these really keto-friendly?

Yes! One medium onion has about 10 grams of net carbs, and Parmesan cheese has less than 1 gram per ounce. Depending on how many chips you make, each chip will have approximately 1-2 grams of net carbs.

Can I make these ahead of time?

While they're best fresh, you can make them a few hours ahead and store them at room temperature. Reheat briefly in the air fryer before serving to restore crispness.

Why did my cheese burn?

This usually happens if the temperature is too high or if you left them in too long. Every air fryer and oven is different, so you may need to adjust the temperature or cooking time. Start checking early and watch them closely.

Can I add other toppings?

Absolutely! Try sprinkling on some chopped fresh herbs like parsley or chives after they come out of the air fryer. You could also add a drizzle of hot honey or balsamic glaze for extra flavor.

What's the best way to slice onions uniformly?

A mandoline slicer is your best bet for perfectly uniform slices. If you don't have one, use a sharp chef's knife and take your time. Uniform slices ensure even cooking.

Ingredients

Scale

1 large yellow onion, sliced into thin rings
1 cup shredded mozzarella cheese (or cheddar for stronger flavor)
1 tbsp grated Parmesan cheese (optional, for extra crispiness)
½ tsp garlic powder
½ tsp smoked paprika (optional)
Salt and black pepper, to taste
Nonstick cooking spray or parchment paper

Instructions

Preheat Air Fryer or Oven
- Air fryer: set to 375°F (190°C).
- Oven: preheat to 400°F (200°C).
Prepare the Onion Rings
- Peel and slice your onion into thin rings.
- Separate the layers into individual rings.
Assemble the Chips
- On a parchment-lined tray or air fryer basket, place small piles of shredded cheese (about 1 tbsp each).
- Top each cheese pile with an onion ring and sprinkle a bit more cheese on top.
- Add seasonings: garlic powder, paprika, salt, and pepper.
Cook Until Golden and Crispy
- Air fry for 8–10 minutes or bake for 12–15 minutes, until cheese is bubbly and edges are golden brown.
Cool & Serve
- Let the chips cool for 2–3 minutes—they’ll crisp up as they rest.
- Enjoy warm or store leftovers in an airtight container for up to 2 days.

Notes

For extra crunch, mix mozzarella with Parmesan.
Avoid overlapping chips—they need space to crisp evenly.
These are amazing dipped in ranch or spicy mayo!
Works with red or white onions, but yellow gives the best flavor balance.
