Instructions

  1. Step 1: Preheat oven to 425°F and line a baking sheet with parchment paper. Remove leaves and trim the stem of 1 medium cauliflower head, then slice into 3/4-inch thick steaks, about 3-4 pieces.
  2. Step 2: In a small bowl, combine 3 tbsp olive oil, 4 minced garlic cloves, 1 tsp salt, and 1/2 tsp ground black pepper. Brush both sides of each cauliflower steak generously with the garlic-oil mixture.
  3. Step 3: Arrange the cauliflower steaks on the baking sheet and roast in the preheated oven for 20 minutes. Flip each steak carefully, then sprinkle 1/4 cup grated Parmesan cheese evenly over the top of each.
  4. Step 4: Continue roasting for another 10 minutes until the cauliflower is tender and the Parmesan is golden and crisp at the edges.
  5. Step 5: Remove from oven and garnish with 2 tbsp chopped fresh parsley before serving warm.
