Step 1

Preheat the oven to 425 degrees Fahrenheit. Line a large baking sheet with parchment paper or aluminum foil.

Step 2

Quarter the zucchini and squash, then slice into 1-inch pieces. Arrange in a single layer on the prepared baking sheet. Drizzle the olive oil over the zucchini and toss to evenly coat.

Step 3

Sprinkle evenly with Italian seasoning, salt, and pepper (more or less to your taste).

Step 4

Roast squash for 12-15 minutes, tossing with a spatula halfway through the cook time to ensure even browning.

Step 5

Garnish with grated Parmesan, if desired, and serve immediately.
