Parmesan Roasted Cauliflower has a thick coating of Parmesan cheese that gets wonderfully browned and crispy when roasted. This is the most flavorful cauliflower I have ever tasted.
Place oven rack in lowest position in oven. Preheat oven to 450 degrees.
Spray a rimmed baking sheet with vegetable cooking spray.
In a medium bowl, stir together Parmesan, cornstarch, thyme, salt and pepper.
Toss cauliflower and oil together in large bowl.
Add Parmesan mixture. Toss until well coated.
Transfer mixture to prepared baking sheet. Use a rubber spatula to scrape out all the cheese mixture from the bowl onto the cauliflower.
Spread cauliflower out evenly.
Roast for 15 minutes. Remove from oven. Flip each piece over with a spatula and return to oven for 3 to 5 more minutes.
It's best to freshly grate Parmesan cheese for this recipe with a rasp-style grater.
