Preheat your oven to 400°F and line a large baking sheet with parchment paper.
In a bowl, toss together the shredded cheddar, parmesan, garlic powder, and onion powder until evenly combined.
Spoon tablespoon-sized mounds of the cheese mixture onto the prepared baking sheet, spacing them about 2 inches apart. Gently flatten each mound with the back of the spoon into thin rounds.
Sprinkle the top of each round generously with everything bagel seasoning, pressing it lightly so it sticks.
Bake for 7 to 9 minutes, until the edges are deeply golden brown and the centers are bubbling. They will look slightly soft but will crisp up as they cool.
Let the crisps cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely until they are crunchy and firm. Serve at room temperature.
