  • 1 medium head cauliflower
  • ¼ cup good olive oil (see tips on "how to buy" in Cooking Oils: The Bare Essentials)
  • cup grated Parmesan cheese (about 1 ounce) or use ½ cup if you like
  • 2 cloves garlic, minced (2 teaspoons)
  • ½ teaspoon kosher salt or more to taste
  • ¼ teaspoon freshly ground pepper or more to taste
  • Garnish: 2-3 tablespoon chopped parsley; extra Parmesan (optional)


  • HEAT OVEN to 425F. Line a pan with foil (for easy clean up) and spray with oil.
  • CUT CAULIFLOWER: Remove leaves, core and larger stems. Cut cauliflower into florets, If you cut them a bit smaller, they will cook faster, but don't cut them too small or they will dry out before they get nicely caramelized. Rinse florets in a colander under cool water. Pat dry with paper or cloth towel. Set aside.
  • SEASON CAULIFLOWER: In a medium bowl, mix together oil, Parmesan, garlic, salt and pepper. Add florets and toss to coat evenly.
  • ROAST AND SERVE: Lay cauliflower florets on pan. Spread them out in a single layer. Roast for 20-30 minutes (depending on size of florets), flipping them once or twice to caramelize/brown all over. Transfer to serving bowl. Garnish with parsley and serve immediately with extra Parmesan if desired.


Make Ahead: Two options: make the whole dish and warm it in a 350F oven for 5-6 minutes; or under-roast the cauliflower by 10 minutes, then finish roasting for the last 10 minutes before serving.
