    If you have been scrolling lately, you have probably seen these viral onion chips popping up everywhere. They are crispy, cheesy, and packed with flavor, yet surprisingly simple to make at home. This recipe takes thinly sliced onions, coats them with cheese and seasoning, and bakes or air fries them into crunchy, savory chips that are perfect for snacking or serving as a low carb side.

    I have tested a few versions of this trend, and this one is the easiest while still giving you that golden, crispy texture everyone is obsessed with. The key is slicing the onions thin and letting the cheese do most of the work. Once you try these, they might replace your usual chips.

    I want to test this recipe using an air fryer to see if the onions will get really crispy but I havenโ€™t yet. I have just used an oven to cook the onions.

    Pro Tips for Onion Chips

    • Slice onions thin. This is the most important step for getting that crispy texture.
    • Do not overcrowd the pan. Give each chip space so it crisps instead of steaming.
    • Watch closely near the end. Cheese can go from golden to burnt quickly.
    • Let them cool before removing. This helps them crisp up fully.
    • Use parchment paper to prevent sticking and make cleanup easier.

    Storage

    These onion chips are best enjoyed fresh, but you can store leftovers in an airtight container at room temperature for up to one day.

    Can I make these without cheese?


    The cheese is what creates the chip texture, so it is not recommended to skip it entirely.

    If they lose some crispiness, reheat them in the air fryer for a few minutes to bring them back to life. Avoid storing them in the fridge since moisture can make them soggy.
