Preheat oven to 350 degrees F and line a baking sheet with parchment paper.
In a medium mixing bowl, add the sliced squash and olive oil. Stir together until the squash slices are coated.
Place the squash rounds on prepared baking sheet in a single layer. Make sure to tap off any excess oil. Leave a little space in between each squash round.
In a small mixing bowl, combine the parmesan cheese, bread crumbs (or panko), garlic powder, onion powder, salt, and pepper.
Spoon the cheese mixture evenly over each squash round and lightly press down.
Bake for 15 minutes or until the squash slices are golden brown on top and softened but not mushy. Remove from the oven, transfer to a dish or platter, garnish with parsley (optional) and enjoy!
