How to Make Whole Roasted Cauliflower with Butter Sauce
👨🍳 Step-by-Step Directions
- Preheat your oven: Set it to 400°F (200°C).
- Prep the cauliflower: Trim the base of the cauliflower, removing leaves and stem while keeping the head intact. Rinse and gently pat dry.
- Simmer in stock: Place cauliflower into a slow cooker or large pot. Add the thyme, bay leaves, and stock. Simmer gently for 12–15 minutes to infuse flavors.
- Drain and transfer: Carefully remove cauliflower and place into a cast-iron skillet or oven-safe dish. Spoon some of the stock over the top.
- Baste with butter: Drizzle the melted butter generously. Sprinkle with more thyme and cracked pepper.
- Roast in the oven: Roast for 10–15 minutes, basting halfway through. Broil for 2 minutes at the end for a golden finish—watch carefully!
- Serve and enjoy: Garnish with fresh thyme. Slice into wedges and serve with the buttery pan juices.
