  • Total Time: 25 minutes
  • Yield: 4 servings

Ingredients

Ingredients

  • 1 large Vidalia sweet onion
  • 8 oz shredded cheese (such as cheddar, mozzarella, or a blend)
  • Fresh thyme (optional, for garnish and aroma)

Instructions

  1. Preheat the oven: Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper to prevent sticking and make cleanup easy.
  2. Slice the onion: Cut the Vidalia onion into even rounds about ¼-inch thick to ensure they cook evenly and hold their shape on the crisps.
  3. Prepare cheese mounds: Place small, evenly spaced mounds of shredded cheese directly onto the parchment-lined baking sheet, creating a base for each onion slice.
  4. Assemble onion and cheese layers: Set one onion round on top of each cheese mound, then sprinkle a little more shredded cheese over the onion slices, allowing some cheese to fall around the edges for extra crispiness.
  5. Bake the crisps: Place the baking sheet in the oven and bake for about 15 minutes or until the cheese is bubbling and deeply golden around the edges, and the onions become tender.
  6. Cool the crisps: Remove the baking sheet from the oven and let the onion crisps cool on the pan for 5 to 8 minutes, allowing the melted cheese to firm up and become crisp.
  7. Serve: Carefully lift each crisp from the parchment using a thin spatula and serve them warm, optionally garnished with fresh thyme for added flavor.

Notes

  • Use a sharp knife or mandoline to slice the onion for uniform thickness.
  • Choose a cheese that melts well and crisps nicely, like cheddar or mozzarella.
  • Fresh thyme adds a wonderful herbal note but is optional.
  • Allow cooling time after baking; cheese crisps better as it cools.
  • Serve immediately after cooling for the best texture and flavor.
