Ingredients
- 1 large head cauliflower
- 2 tbsp olive oil
- 2 cloves garlic
- 1 tbsp fresh parsley
- 1 tsp fresh thyme
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1 tbsp unsalted butter
Instructions
- Step 1: Preheat oven to 425°F. Cut 1 large head cauliflower into 1-inch thick steaks (about 2 cups total), discarding the core. Place steaks on a parchment-lined baking sheet, drizzle with 2 tbsp olive oil, and season with 1/2 tsp salt and 1/4 tsp black pepper. Toss to coat evenly.
- Step 2: Roast for 20-25 minutes, flipping halfway through, until the cauliflower is golden brown and tender when pierced with a fork.
- Step 3: Melt 1 tbsp unsalted butter in a small saucepan over medium heat. Add 2 minced garlic cloves and cook for 1 minute until fragrant, then stir in 1 tbsp chopped fresh parsley and 1 tsp chopped fresh thyme.
- Step 4: Remove cauliflower from oven and drizzle with the garlic herb butter sauce. Serve immediately.
