Roasted Cauliflower au Gratin


  • 2 large heads cauliflower

  • 3 tablespoons extra virgin olive oil (EVOO)

  • Salt and black pepper

  • 1 cup ricotta cheese

For the topping:

  • 2 tablespoons extra virgin olive oil (EVOO)

  • 3 tablespoons butter

  • 1 garlic clove, grated

  • 1 lemon, zested, reserve the lemon for squeezing for juice for garnish

  • 2 tablespoons parsley, chopped

  • 1 cup breadcrumbs

For the sauce:

  • 2 tablespoons butter

  • 4 tablespoons flour

  • 2 cups milk

  • Salt and black pepper

  • Freshly grated nutmeg


Pre-heat the oven to 400°F. Chop the cauliflower into medium to large bite-size florets. Toss the cauliflower with EVOO, salt and pepper to coat. Roast on a baking sheet until just barely tender but slightly crispy, about 15 minutes. For the topping, in a large skillet over medium heat, add 2 tablespoons EVOO and the butter. When the butter melts, add the garlic, lemon zest and parsley and cook for 1-2 minutes, or until fragrant. Add the breadcrumbs and toast until golden. Transfer to a bowl and reserve. Meanwhile, make the sauce: Melt the butter in a saucepot over medium heat. Stir in the flour and cook for a few minutes, stirring constantly, until it starts to smell slightly nutty. Stir in the milk, salt, pepper and nutmeg and bring to a simmer. Remove from the heat and reserve. Turn down the oven to 375°F. Mix the cauliflower and sauce in a casserole dish, then dollop with ricotta. Bake for 15 minutes, until golden brown. Finish the dish with a sprinkling of the breadcrumb mixture and a squeeze of lemon juice over top. This is one of many "Yum-o!" recipes – it's good and good for you.
