Recipe Features

Crispy onion chips are super easy to make and so fun to serve! They'll be a hit at parties, game days, or anytime you want a flavorful snack.
Absolutely bursting with flavor from the Parmesan cheese, the allium flavor of the onions, and the delicious spice blend.
Serve with your favorite dip, like tzatziki, ranch, or sour cream!

Ingredients

Onions - I recommend using yellow onions as they're milder in flavor. Sweet onions (like Vidalias) would also be wonderful!
Parmesan Cheese - use shredded (not grated) parmesan cheese. This will create a beautiful lacy lattice of cheese to hold the onions.
Olive Oil - brush the onions with a little olive oil to help crisp them up.
Seasonings - you'll use smoked paprika, garlic powder, salt, and pepper to season the onion chips.

Step 2: Spread Parmesan into a layer covering a parchment-lined baking sheet.

Tips for Making this Recipe

Cooking Tips - Check your onions after 18 minutes of cook time. They may be ready or may need up to 4 to 5 more minutes, depending on how thickly you slice your onions.
Specialty Ingredients - Smoked paprika if often used in onion rings, so it will give you the most similar flavor, but it's not absolutely necessary and can be substituted for regular paprika if you'd prefer!
Recommended Tools - I highly recommend using a mandoline to slice your onions. This guarantees a thin, uniform slice. Just be sure to wear a cut-proof glove to protect your fingers, as mandolines are super sharp!

Storage

While they are best served fresh (and don't reheat well), here are some ideas for saving leftovers. I do not recommend making this recipe ahead of time.

Storage - leftover onion chips can be stored for up to 3 days in the refrigerator in an airtight container.
Reheat - Reheating is tricky, as the parmesan tends to melt. I recommend reheating in the oven rather than in a pan on the stovetop or in the microwave. It still will not be as crispy in the oven, but it's the best option.
