Broccoli Cauliflower Roast


  • 1 pound broccoli florets
  • 1 pound cauliflower florets
  • 2 cups milk, heated
  • 4 tablespoons unsalted butter
  • 4 tablespoon all-purpose flour
  • 1 cup cheddar cheese, grated
  • 1 cup Monterey Jack cheese, grated
  • 1 teaspoon ground mustard
  • salt and fresh ground pepper, to taste


  1. Preheat oven to 400°F and lightly grease a baking dish.
  2. Bring a large pot of salted water to a boil and add the broccoli and cauliflower, cooking until crisp-tender, about 4 minutes. Drain and place in prepared baking dish.
  3. Meanwhile, make the cheese sauce. Melt butter in a medium sauce pan over medium heat and whisk in the flour. Cooking, stirring constantly, for 1-2 minutes.
  4. Slowly add the warm milk, whisking continuously. Continue cooking until mixture has thickened.
  5. Add mustard, season with salt and pepper, and turn off the heat. Add 1/2 of the cheddar cheese and 1/2 of the Monterey Jack cheese and stir until melted and combined.
  6. Pour cheese sauce over broccoli and cauliflower in prepared baking dish and top with remaining cheeses.
  7. Bake until bubbly and golden brown, about 20 minutes. Let sit 5 minutes before serving. Enjoy!
