Ingredients You’ll Need
| Ingredient | Amount | Notes |
|---|---|---|
| White onions | 2 small | Sliced into ¼-inch rings |
| Parmesan cheese | 7 oz shredded | Finely shredded works best |
| Olive oil | ½ tbsp | For brushing rings before baking |
| Salt | To taste | Optional but recommended |
| Garlic powder | To taste | Adds depth and flavor |

Tip: Use pre-shredded parmesan for convenience, but avoid “powdery” cheese—it won’t melt and crisp the same.
How to Make Onion Ring Chips (Step-by-Step)
Step 1: Prep the Oven and Pan
Set your oven to 400°F (204°C). Line a 12×17-inch rimmed baking tray with parchment paper to prevent sticking and make cleanup easier.
Step 2: Layer the Cheese
Sprinkle the shredded parmesan cheese over the parchment in a thin, even layer. This will serve as the crispy base for the onion rings, so aim to cover most of the surface.
Step 3: Place the Onion Rings
Arrange the onion slices on top of the cheese in a single, non-overlapping layer. Keep them spaced slightly apart so each one cooks evenly and soaks up that cheesy crunch.
Step 4: Add Oil and Seasoning
Brush the tops of the onion rings lightly with olive oil. Then season with a pinch of salt, garlic powder, and paprika to your preference.
Step 5: Bake Until Crispy
Transfer the tray to the oven and bake for 18–20 minutes, or until the cheese turns a deep golden brown and the onions become soft with caramelized edges.
Step 6: Let Cool and Enjoy
Allow the tray to cool for 5 to 10 minutes. The cheese will firm up as it rests. Once cooled slightly, break into individual crispy pieces and enjoy them warm or at room temperature.
Flavor Variations You’ll Want to Try
Air Fryer Version – Cook in batches at 375°F for 10–12 minutes for even crispier chips

- With dips – Pair with hummus, guacamole, or Lazy Tzatziki
