A recipe for roasted cauliflower. Not that you really need one. But I liked the addition of onion and Parmesan. And the sprinkling of thyme is nice. So yeah, maybe you do need a recipe. Thanks again, Bon Appetit.
Preheat oven to 425°. Cut 1 head cauliflower into florets; toss on a large rimmed baking sheet with 1 sliced medium onion, 4 thyme sprigs, 4 unpeeled garlic cloves, and 3 tablespoons olive oil; season with kosher salt and freshly ground black pepper. Roast, tossing occasionally, until almost tender, 35-40 minutes. Sprinkle with 1/2 cup grated Parmesan, toss to combine, and roast until cauliflower is tender, 10-12 minutes longer.
