Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper. Spray lightly with cooking spray.

Set up three shallow dishes: one with flour, one with beaten eggs, and one with breadcrumbs mixed with half of the Parmesan, garlic powder, onion powder, salt, and pepper.

Slice the yellow squash into even rounds about half an inch thick. Pat the slices dry.

Dip each squash slice into flour, then beaten eggs, finally roll in the breadcrumb mixture, pressing gently to adhere.

Arrange the coated squash slices in a single layer on the baking sheet. Spray the tops lightly with cooking spray.

Bake for 20-25 minutes, flipping halfway through, until golden brown and crispy.

Remove from the oven and sprinkle with remaining Parmesan cheese. Serve warm.
