Total Time30 minutes
Course: Side Dish
Cuisine: American
Diet: Gluten Free, Vegetarian
Servings (change as needed): 4 (or 3 larger servings)

Ingredients

  • 1 medium whole head of cauliflower, Note 1
  • 1/4 cup good olive oil (see tips on best oils for cooking)
  • 1/3 cup grated Parmesan cheese (about 1.5 ounces) use more if you like
  • 2 garlic cloves, minced (2 teaspoons)
  • 1/2 teaspoon kosher salt or more to taste
  • 1/4 teaspoon ground black pepper or more to taste

Optional garnish

  • 2-3 tablespoons fresh chopped parsley, extra Parmesan, lemon zest or pesto

Instructions

  • HEAT OVEN to 425F/218C. Line a large baking sheet with parchment paper of aluminum foil, sprayed with oil (for easy clean up)
  • CUT CAULIFLOWER: Remove leaves, core and larger stems. Cut cauliflower into bite-size pieces, 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 WITH CHEESE MIXTURE: In a large bowl, mix together oil, Parmesan, garlic, salt and pepper. Add florets and toss to coat evenly.
  • ROAST AND SERVE: Lay cauliflower florets in a single layer on on pan. Spread them out in a single layer. Roast in preheated oven for 20-30 minutes (depending on size of florets), flipping them once or twice until golden brown and caramelized. Transfer to serving bowl. Garnish as you like with parsley, extra Parmesan, etc.

Notes

  1. Cauliflower alternatives: Instead of a regular cauliflower head, try the looser packed baby cauliflower (fioretto). If you're not a cauliflower fan, try brussels sprouts. Cut them in half (except for small ones), shed the outer leaves, then toss with the cheese mixture and roast.
  2. Flavor add-ins: Add some heat with red pepper flakes. Or feel free to add extra flavor to the cheese mixture with dried thyme or Italian seasoning.
  3. Shortcuts
    • Buy cauliflower florets that have been pre-cut 
    • Substitute fresh garlic with minced garlic in a jar or frozen garlic cubes. Or, use 1/4 tsp garlic powder.
    • Use pre-grated Parmesan cheese.
  4. Make ahead:
    • 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.
    • Store leftovers in an airtight container for up to 2-3 days.
