  • Adjust an oven rack to the middle position and preheat oven to 400 degrees. Line a large rimmed baking sheet with foil for easy cleanup.
  • In a large bowl, add cauliflower, olive oil, garlic, lemon juice, and salt and pepper (I like at least 1/2 teaspoon salt and 1/4 teaspoon pepper; sometimes I do a little more).
  • Transfer to prepared baking sheet. Roast until florets are tender-crisp and browning around the edges, about 35 to 40 minutes.
  • Remove from oven and sprinkle with parmesan cheese and toss to coat. Return to oven and bake until cheese is melted, about 1 to 2 minutes longer. 



  1. Cauliflower: Look for one that is bright off-white, firm and heavy, without any brown discoloration or soft spots. Cut the cauliflower florets into pieces that are all about the same size so they cook evenly.
  2. Lemon: The zest of one lemon (about 1 teaspoon) can be added with the lemon juice. Just zest the lemon before you cut it to squeeze it.
  3. Parmesan: Any hard, aged cheese will work well instead. Think Parmesan, grated Asiago, pecorino, or Romano cheese.
  4. Yield: This recipe makes 8 servings.
  5. Storage: Store leftovers covered for up to 4 days.
