Choosing quick-roasting vegetables like zucchini and summer squash is obvious when you need a fast side dish for dinner. Olive oil, salt, and pepper are the only seasonings you’ll need and this recipe will be on the table in just 20 minutes.
Preheat oven to 425°F. Cover a large baking sheet (see Tip) with foil; lightly coat with cooking spray. Set aside. Halve squash lengthwise. Cut the squash into ¼-inch-thick slices.
Toss the squash slices with oil, kosher salt, and pepper in a large bowl. Arrange the slices in a single layer on the prepared baking sheet. Roast for 10 to 15 minutes or until the slices are tender and golden.
