Ingredients
- 2 large yellow onions
- 140 grams (5 ounces) shredded Parmesan cheese
- 15 milliliters (1 tablespoon) olive oil
- 2.5 milliliters (½ teaspoon) sea salt
- 2.5 milliliters (½ teaspoon) garlic powder
- 2.5 milliliters (½ teaspoon) smoked paprika
- 1.25 milliliters (¼ teaspoon) black pepper
Instructions
- Preheat your oven to 200°C (400°F) to prepare for baking the onion chips, ensuring it reaches the optimal temperature for crisping.
- Using a mandolin slicer set to approximately 1.1 mm (1/28 inch) thickness, or a very sharp chef's knife, thinly slice the yellow onions into even rounds. Uniform thickness is crucial for consistent cooking and ultimate crispiness.
- Line a large baking sheet with parchment paper, then spread the shredded Parmesan cheese evenly over the parchment to form a consistent base layer for the onion slices. This cheese layer will become the crispy, flavorful foundation of the chips.
- Carefully arrange the thinly sliced onion rounds in a single layer over the Parmesan cheese, ensuring there is minimal overlap. Giving each onion slice ample space allows for even baking and maximum crispness.
- Gently brush the tops of the onion slices with the olive oil. Then, evenly sprinkle the sea salt, garlic powder, smoked paprika, and black pepper over the oiled onions. This layering of flavor will infuse every chip with a rich, savory aroma.
- Place the baking sheet into the preheated oven and bake for 18 to 20 minutes. Bake until the Parmesan cheese is deeply golden brown and audibly crispy, and the onion slices appear tender-crisp.
- Remove the baking sheet from the oven and allow the baked onion ring chips to cool completely on the baking sheet for several minutes. As they cool, they will further firm up and become perfectly crispy. Once cooled, carefully slice them into individual chip-sized pieces using a sharp knife or a pizza cutter, and serve immediately.
Tools You’ll Need

- Measuring spoons
- Cutting board
- Pizza cutter (optional, for slicing after baking)
Essential Success Tips
- Uniform Slicing: The key to perfectly crispy chips is extremely thin and even onion slices. A mandolin is highly recommended for achieving this consistency.
- Single Layer is Essential: Do not overcrowd your baking sheet. Onions need space to dry out and crisp up properly. If necessary, use two baking sheets.
- Parchment Paper is a Must: Always use parchment paper; it prevents sticking and makes it much easier to remove the delicate chips once baked.
- Monitor Oven Closely: Ovens can vary, so keep a close eye on the chips during the last few minutes of baking to prevent the Parmesan from burning.
- Cool Completely: Allowing the chips to cool fully on the baking sheet is crucial. They will crisp up significantly as they cool.
Professional Cooking Secrets
- Enhanced Umami: For an extra layer of savory depth, mix a very small dash of tamari or Worcestershire sauce (if not strictly vegetarian) into the olive oil before brushing.
- Sweet-Savory Balance: A tiny pinch of brown sugar or maple sugar sprinkled with the other seasonings can create a beautiful caramelized edge and balance the savory flavors.
- Aromatic Boost: Gently toast a few coriander seeds or fennel seeds, crush them, and sprinkle them over the onions for an unexpected aromatic complexity.
Notes
- Storage: These chips are best enjoyed fresh out of the oven for maximum crispness. If you have leftovers, store them in an airtight container at room temperature for up to 2 days. They may lose some crispness, but can be briefly re-crisped in a low oven (150°C/300°F) for 5-7 minutes.
- Flavor Variations: Feel free to experiment with other seasonings such as chili powder, Italian seasoning, or a touch of cayenne pepper for a spicy kick. Nutritional yeast can also be added for a nuttier, cheesier flavor if you want to reduce dairy.
- Serving Suggestion: Serve these chips on their own as a snack, alongside a sandwich or burger, or with a simple dip like marinara sauce, ranch dressing, or a creamy aioli.
Frequently Asked Questions
Can I use red onions instead of yellow onions?
While yellow onions offer a classic mild-sweet flavor when baked, red onions can also be used. They tend to be slightly sharper and will yield a more vibrant color, but the baking process mellows their intensity nicely.
My onion chips aren't getting crispy, what went wrong?
The most common reasons for non-crispy chips are slicing the onions too thick, overcrowding the baking sheet, or not baking them long enough. Ensure your slices are paper-thin, that there's plenty of space between them, and bake until the Parmesan is a deep golden brown and crunchy.
Is there a dairy-free alternative for the Parmesan cheese?
For a dairy-free version, you can try using a plant-based Parmesan alternative. Alternatively, a generous sprinkle of nutritional yeast mixed with a small amount of almond flour or finely ground cashews can provide a savory, 'cheesy' crust, though the texture will be slightly different.
