Preheat oven to 400°F (200°C). Line a sheet pan with parchment paper and generously brush with olive oil.
Combine cottage cheese, egg, salt, and oregano in a small bowl. Mix well.
Spoon 1½ tablespoons of the cottage cheese mixture onto the sheet pan. Spread each dollop out slightly. Place an onion slice on top, pressing gently. Drizzle with olive oil, then season with salt, pepper, and thyme.
Bake for 24–28 minutes, until edges are golden brown and crispy.
Let cool for a couple of minutes, then carefully lift the crisps with a spatula. Enjoy warm!
