Instructions

To Make the Filling:

  • Preheat your oven to 375°F. Grease a 9x13-inch baking dish.
  • In a large pot of boiling salted water, blanch the broccoli and cauliflower florets for 3-4 minutes, or until just tender. Drain and set aside.
    4 cups broccoli florets, 4 cups cauliflower florets
  • In a large saucepan, melt the butter over medium heat. Add the chopped onion and sauté until softened, about 5 minutes. Add the minced garlic and cook for another minute. Stir in the flour and cook for 1-2 minutes until lightly browned.
    2 tablespoons unsalted butter, 1 small onion, 2 cloves garlic, ¼ cup all-purpose flour
  • Gradually whisk in the milk and heavy cream and cook until the sauce thickens, about 5-7 minutes. Stir in the shredded cheddar cheese, grated Parmesan cheese, Dijon mustard, salt, and pepper until the cheese is melted and the sauce is smooth.
    1 cup milk, 1 cup heavy cream, 1 cup shredded cheddar cheese, ½ cup grated parmesan cheese, 1 teaspoon Dijon mustard, ¼ teaspoon smoked paprika, Salt and pepper to taste
  • Place the blanched broccoli and cauliflower florets in the prepared baking dish. Pour the cheese sauce over the vegetables and stir to coat evenly.

To Make the Topping:

  • In a small bowl, mix the panko breadcrumbs with the melted butter and sprinkle over the top of the casserole.
    1 cup panko breadcrumbs, 3 tablespoons unsalted butter
  • Bake, uncovered, for 20-25 minutes, or until the casserole is bubbly and the topping is golden brown.
  • Let the casserole cool for a few minutes before serving.
