Ingredients

  • 1 tablespoon olive oil
  • ¼ cup Panko*
  • ½ cup freshly grated parmesan divided
  • 1 head cauliflower cut into florets
  • 3 tablespoons unsalted butter
  • 3 cloves garlic minced
  • 1 large shallot diced
  • 3 tablespoons all-purpose flour
  • 2 teaspoons chopped fresh thyme leaves
  • 1 ½ cups whole milk
  • ½ cup heavy cream
  • 1 teaspoon Dijon mustard
  • Kosher salt and freshly ground black pepper to taste
  • 1 cup shredded Mozzarella cheese
  • 3 sprigs fresh thyme

Instructions

    Cup of Yum
  1. Preheat oven to 400 degrees F.
  2. In a small bowl, combine olive oil, Panko and 1/4 cup Parmesan; set aside.
  3. Place cauliflower in a steamer basket and set over boiling water. Cover and steam until crisp-tender, about 4-5 minutes; drain well.
  4. Melt butter in a large skillet over medium heat. Add garlic and shallots, and cook, stirring frequently, until fragrant, about 2 minutes.
  5. Whisk in flour and thyme until lightly browned, about 1 minute. Gradually whisk in milk, heavy cream and Dijon. Cook, whisking constantly, until incorporated and slightly thickened, about 4-5 minutes. If the mixture is too thick, add more milk as needed; season with salt and pepper, to taste.
  6. Stir in cauliflower, mozzarella and remaining 1/4 cup Parmesan until the cheeses have melted, about 1-2 minutes. Sprinkle with Panko mixture.
  7. Place into oven and bake until golden brown and bubbly, about 20-25 minutes.
  8. Serve immediately, garnished with thyme, if desired.

Notes

  • *Panko is a Japanese-style breadcrumb and can be found in the Asian section of your local grocery store.
