Preheat the Oven
Position an oven rack in the center and preheat your oven to 425°F (220°C). This high temperature will help achieve a beautifully melted and golden topping.
Prepare the Baking Sheet
Line a baking sheet with aluminum foil or parchment paper, lightly sprayed with nonstick cooking spray. This will prevent the squash from sticking and make cleanup easier.
Prepare the Squash
Rinse the yellow squashes under cool water and pat them dry with a clean kitchen towel. Slice each squash into 1/4-inch thick rounds. Aim for uniform slices to ensure even cooking.
Arrange the Squash
Lay the squash rounds on the prepared baking sheet in a single layer, ensuring they are spaced closely but not overlapping. This allows for even roasting and browning.
Season the Squash
Sprinkle each round lightly with garlic salt and freshly ground black pepper. The garlic salt will infuse the squash with a delicious flavor, while the pepper adds a touch of warmth.
Add the Parmesan
