Ingredients
  

Main Ingredients

  • 3 Tbsp Olive oil
  • 4 cloves Garlic, minced
  • 1 large head cauliflower, cut into florets (about 2 3/4 lb)
  • 1/4 tsp Salt
  • 1/4 tsp Black pepper
  • 1/3 cup Grated Parmesan cheese
  • 1 Tbsp Fresh parsley, chopped

Optional Ingredients

  • Lemon wedges (for brightness at the end)
  • 1/2 tsp Smoked paprika (for deeper flavor)
  • Red pepper flakes (pinch for heat)
  • Extra Parmesan (for a cheesier finish)

Instructions
 

Preparation

  • Preheat oven to 450°F.
  • Grease a shallow roasting pan or a large broiler-safe baking dish.
  • Cut cauliflower into florets (try to keep them similar size so they roast evenly). Dry them well—less moisture = better browning.

Mixing / Assembling

  • In a large bowl, stir together olive oil and minced garlic.
  • Add cauliflower florets and toss until every piece is coated.
  • Spread cauliflower in the prepared pan in a single layer.
  • Sprinkle with salt and pepper.

Cooking / Baking

  • Roast for about 25 minutes, stirring once halfway through, until florets are tender and starting to brown.
  • Turn on the broiler. Sprinkle cauliflower evenly with Parmesan.
  • Broil for 3–5 minutes until the cheese is golden and lightly crisp (watch closely—broilers work fast).

Resting / Finishing

  • Remove from oven and sprinkle with fresh parsley.
  • Optional: add a quick squeeze of lemon for a fresh, bright finish.
  • Serve warm.

Notes

For best texture, roast in a single layer with space between florets—crowding causes steaming instead of browning. Add a pinch of red pepper flakes or smoked paprika before roasting for enhanced flavor.
