Equipment

Ingredients

  • 24 ounces cauliflower florets
  • Kosher salt
  • 3 tablespoons butter divided
  • 2 tablespoons all-purpose flour
  • 1 cup 2% milk
  • ½ teaspoon freshly ground black pepper
  • Pinch of grated nutmeg
  • ½ cup freshly grated Swiss cheese or Gruyere
  • ¼ cup freshly grated Parmesan divided
  • 2 tablespoons seasoned bread crumbs

Instructions

  • PREPARE: Preheat the oven to 375˚ F and adjust the oven rack about 10 inches from the top.
  • BOIL THE CAULIFLOWER: Fill a large pot with water and 1 teaspoon of salt; bring to a boil. Add the cauliflower florets and boil until they’re just soft, about 6 minutes. Drain, return to the pot and set aside.
  • MAKE A ROUX: Heat a medium saucepan over medium-low heat, melt 2 tablespoons of the butter. Once the butter has fully melted, whisk in the flour.
  • FINISH THE SAUCE: Slowly pour the milk into the pot while stirring. Increase the heat to medium and bring to a boil. Continue boiling and stirring until it has thickened, about 1-2 minutes.
  • Remove from the heat and add ½ teaspoon of salt, the pepper, nutmeg, and the Gruyere.
  • COMBINE EVERYTHING: Pour the sauce on the cauliflower and toss to coat the cauliflower in the sauce. Pour the mixture into an 8X8 pan.
  • ADD TOPPINGS: Sprinkle an even layer of parmesan and breadcrumbs over the top of the cauliflower. Melt the remaining butter and drizzle over the top of the breadcrumbs.
  • BAKE: Bake for 25 to 30 minutes, until the top is golden brown. Allow to cool for about 5 minutes before serving.
