🛒 Ingredients

For the Onion Chips:

  • 2 small white onions, sliced into ¼-inch (0.6 cm) thick rings

  • 200 g (7 oz) shredded parmesan cheese

  • Olive oil (for drizzling)

For Seasoning (to taste):

  • Salt

  • Garlic powder

  • Onion powder

  • Paprika

🍳 Step-by-Step Instructions

  1. Preheat & Prep the Tray
    Preheat your oven to 400°F (200°C).
    Line a 12×17 inch (30×43 cm) rimmed baking sheet with parchment paper — avoid using foil or wax paper.

  2. Create a Cheesy Base
    Evenly sprinkle the shredded parmesan across the entire parchment-lined tray, creating a thin layer. This will form the crispy base for your chips.

  3. Add the Onion Rings
    Carefully place the onion slices on top of the parmesan. Lay them flat and close together, but don’t overlap them.

  4. Drizzle & Season
    Lightly brush or drizzle olive oil over the onion tops.
    Sprinkle with salt, garlic powder, onion powder, and paprika — season boldly for maximum flavor!

  5. Bake Until Golden
    Place the tray in the oven and bake for 18 minutes, or until the cheese is crispy and golden and the onions are nicely roasted.

  6. Cool & Break Apart
    Remove from the oven and let the tray cool for 5–10 minutes. Then break the cheesy sheet into individual chips or leave in rustic clusters. Serve as-is or with a dip!

💡 Pro Tips

🌬 Let Them Cool Completely – This ensures they crisp up even more as the cheese firms. Patience = perfect crunch!
🧀 Use Freshly Shredded Parmesan – Pre-grated cheese has anti-caking agents that can affect crispiness.
🔥 Want a spicy kick? – Add a pinch of cayenne or chili powder before baking.
🥣 Perfect for Dips – Try with ranch, sour cream, or your favorite low-carb dip!

📌 FAQs

Can I use red or yellow onions instead of white?
Yes! White onions are mild and sweet when baked, but yellow or red onions also work well — just expect a slightly different flavor.

Can I make this dairy-free?
Unfortunately, parmesan is essential for the crispiness here. However, some vegan parmesan alternatives may work — results can vary.

How do I store leftovers?
Let them cool completely, then store in an airtight container at room temperature for up to 2 days. Re-crisp in the oven if needed.

Can I air fry them instead?
You can try small batches in the air fryer at 375°F (190°C) for 8–10 minutes — just keep an eye on them so they don’t burn!
