Step 1

Preheat an oven to 400°F (200°C). Line a baking sheet with parchment paper.

Step 2

Place the cauliflower, stem side down, on a cutting board and cut into 3/4-inch (2-cm) slices. Place the slices on the prepared baking sheet. Brush the cauliflower with 1 Tbs. of the olive oil and season lightly with salt and pepper. Roast until the cauliflower is soft and caramelized, about 20 minutes.

Step 3

While the cauliflower is roasting, make the brown butter by melting the butter in a small saucepan over medium heat. Cook, swirling the pan, until the butter foams and begins to brown, about 3 minutes. Be careful not to burn the butter. Remove from the heat and cover to keep warm.

Step 4

Using a spatula, carefully transfer the cauliflower slices to a platter. Drizzle with the brown butter and sprinkle evenly with the parsley and capers. Squeeze the lemon halves over the cauliflower to taste and serve immediately. Serves 4.
