Step-by-Step Guide to Make Onion Chips
Onion chips are crispy, flavorful snacks made from thinly sliced onions. They can be baked, fried, or air-fried and are great for snacking or topping burgers and salads.
Step 1: Choose the onions
Use large onions such as yellow, white, or sweet onions. Peel off the outer skin and wash them well.
Step 2: Slice thinly
Cut the onions into very thin rings or strips. Thin slices help them cook evenly and become crispy.

Step 4: Season the onions
Place the onion slices in a bowl. Add a little oil, salt, black pepper, and optional seasonings like paprika or garlic powder. Toss until lightly coated.
