Ingredients needed

You don’t need a big grocery list here. In fact, the simpler you keep it, the better the flavor shines. Here’s exactly what I use when I make a batch for movie night or when friends swing by without warning.

• 2 medium sweet onions, thinly sliced into rings or half-moons
• 2 cups shredded cheese, divided: I like a 50-50 mix of sharp cheddar and mozzarella for flavor and melt
• 2 tablespoons grated Parmesan for extra savory crunch
• 1 tablespoon olive oil
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1/2 teaspoon smoked paprika or chili powder, optional for a little warmth
• Salt and black pepper to taste
• Optional for low carb structure: 2 teaspoons almond flour or crushed pork rinds (helps bind loose cheese)
• Optional fresh topping: chopped chives or parsley

Choosing the right onion

Sweet onions like Vidalia are amazing because they soften and caramelize just a touch while baking, bringing out their natural sweetness. Yellow onions also work well. Red onions can be used too if you want a sharper bite and deeper color at the edges. The key is slicing them thin and even so they crisp properly and cook at the same rate.

Pro tip: If your onions are a little strong, soak the slices in cold water for 10 minutes, then pat very dry. It mellows the bite without losing that onion punch.

How to make Onion Ring Chips

This method gives you that perfect balance of golden, lacy cheese and lightly caramelized onion. You can use the oven or the air fryer. Both work beautifully.

Oven, air fryer, or skillet

Oven method:

1. Preheat to 400°F. Line two sheet pans with parchment. Lightly brush the paper with olive oil so the crisps release cleanly.

2. Toss the onion slices with olive oil, garlic powder, onion powder, smoked paprika, salt, and pepper. If using almond flour or crushed pork rinds, sprinkle it in and toss again. The coating should feel light, not heavy.

3. On your pans, make small mounds of shredded cheese about 2 inches wide. I do a thin layer of cheddar, a few onion strands, then a little mozzarella and Parmesan on top. Don’t make them too big or they won’t crisp evenly.

4. Bake for 9 to 13 minutes until the edges are bubbling, deep golden, and lacy. Let them sit on the pan for 3 to 4 minutes before moving so they set properly.

Air fryer method:

1. Set to 360°F. Line the basket with perforated parchment or use a lightly greased sheet of regular parchment cut to fit.

2. Arrange small piles of cheese with onion strands in the center. Air fry 5 to 8 minutes, checking near the end so nothing burns. Pull when the edges are well browned and the centers look set.

Skillet method (fast but watchful):

1. Warm a nonstick pan over medium heat with a light film of oil.

2. Add tiny piles of cheese, then a few onion strands, then more cheese. Cook until the edges darken and crisp, then gently flip for 20 to 30 seconds. Transfer to a rack to cool.

Note on moisture: Pat your onions dry before assembling. Extra moisture fights crispness. And give each mound a little breathing room on the pan so the heat can circulate.

Tips from my kitchen

Cheese blend matters: Cheddar gives flavor, mozzarella gives pull, and Parmesan gives crunch. I like a mix. If you only have one cheese, use what you’ve got, but make sure it’s a good melter.

Don’t overpack the onions: A few strands per crisp is enough. If you pile too many, the cheese can’t seal and you lose that delicate lacey edge.

Let them cool: As tempting as it is to snatch one off the pan, a few minutes on a wire rack helps achieve that shatter-crisp texture. They firm up as they cool.

Flavor twists: Try a dusting of ranch seasoning, everything bagel spice, or a pinch of red pepper flakes. A tiny drizzle of hot honey when they’re warm is also wildly good if you like sweet heat.

Batch and store: These are best fresh, but if you do store them, keep them in a paper towel lined container at room temp for up to 24 hours. Re-crisp in a 325°F oven for 3 to 5 minutes.

Make it a meal: Pair with a big salad or a protein plate. For another cheesy side that surprises people, try these cheesy baked cabbage steaks that roast up tender in the middle with crispy edges.

“I made a double batch for game night and they vanished in minutes. The pan-to-table time was so quick, I actually got to sit and enjoy the game.”

Dips to serve it with

Quick mix ideas

I’m a dip person, so I rotate a few depending on what we’re craving. These are all super easy and match the savory sweetness of the onions.

• Cool ranch yogurt dip: plain Greek yogurt, ranch seasoning, squeeze of lemon
• Smoky chipotle mayo: mayo, chipotle in adobo, touch of lime and honey
• Garlic-herb sour cream: sour cream, minced garlic, dill, chives, black pepper
• Spicy marinara: warm your favorite tomato sauce and stir in grated Parmesan
• Green goddess riff: yogurt, parsley, basil, lemon, garlic, olive oil

If you want a party-level dip that everyone will crowd around, this Margherita pizza dip is bubbly, cheesy, and tangy. For something crunchy to go with your crunchy snack, these spinach dip cheese crisps are a fun duet on a snack board.

I also like to drizzle a little balsamic glaze on a few crisps and serve them with thinly sliced apples or pears. The sweet and tart combo totally flatters the onions.

Common Questions

How thin should I slice the onions?

About 1/8 inch. The thinner the slice, the easier it crisps. Use a sharp knife and keep the pieces similar in size.

Can I make them ahead?

They’re best fresh, but you can bake a batch, cool completely, then re-crisp for a few minutes in a 325°F oven right before serving.

What cheeses work best?

Cheddar, mozzarella, Monterey Jack, and Parmesan. A blend gives the best texture. Avoid very low-moisture cheese only, or they can get brittle.

Do these work in an air fryer?

Yes. Use 360°F and keep the piles small. Check often for browning at the edges.

What can I serve with them for a full meal?

Keep it simple with a leafy salad or a rice side. If you love onion flavor, this comforting French onion rice plays nicely with the same savory notes.

Let’s get you crispy with it

If you’ve got onions and cheese, you’re halfway to a pan of Cheesy Onion Crisps. Keep the slices thin, don’t overcrowd the mounds, and let them cool so the edges can turn delightfully brittle. I love how flexible this recipe is, from oven to air fryer, and how easy it is to tweak the seasonings to your taste.
