Ingredients

  • 7 tablespoons — butter, divided

  • ½ cup — all-purpose flour

  • 3 cups — milk

  • 5 ounces — truffled pecorino cheese, grated, or more to taste

  • 1 teaspoon — salt, or to taste

  • 1 pinch — cayenne pepper, or more to taste

  • 1 pinch — ground nutmeg

  • 1 large head — cauliflower, cored and separated into florets

  • 2 tablespoons — bread crumbs

  • 2 tablespoons — finely grated Parmigiano-Reggiano cheese, or more to taste

  • 1 tablespoon — extra-virgin olive oil

  • 1 tablespoon — chopped fresh chives, or to taste

Directions

  • Preheat the oven to 425 degrees F (220 degrees C). Butter a 9×13-inch baking dish with 1 tablespoon butter.
  • Melt remaining 6 tablespoons butter in a saucepan over medium heat. Whisk flour into butter; cook and stir until raw flour taste cooks off, 2 to 3 minutes.
  • Gradually whisk milk into flour mixture. Increase heat to medium-high; cook and stir until mixture thickens and comes to a simmer, 5 to 10 minutes. Stir truffled pecorino cheese, salt, cayenne pepper, and nutmeg into milk mixture until cheese sauce thickens.
  • Bring a large pot of salted water to a boil; add cauliflower and cook until slightly tender, about 6 minutes. Drain and transfer cauliflower to the prepared baking dish.
  • Spread cheese sauce evenly over cauliflower. Dust with bread crumbs and Parmigiano-Reggiano cheese. Drizzle olive oil on top and sprinkle with a pinch of cayenne pepper.
  • Bake in the preheated oven until browned and bubbling, about 30 minutes. Garnish with chopped fresh chives.
