by

This cheesy broccoli and cauliflower gratin is the perfect blend of creamy, cheesy goodness and tender vegetables, making it a standout side dish for any meal. The vibrant broccoli and cauliflower florets are blanketed in a rich, velvety cheese sauce and topped with a crispy breadcrumb crust.

Ingredients:

  • 1 medium head of broccoli, cut into florets
  • 1 medium head of cauliflower, cut into florets
  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 2 cups whole milk (warm)
  • 1 cup shredded sharp cheddar cheese
  • 1/2 cup grated Parmesan cheese
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon nutmeg (optional)
  • Salt and pepper, to taste
  • 1 cup panko breadcrumbs
  • 2 tablespoons olive oil
  • 2 tablespoons chopped fresh parsley (optional, for garnish)
  • Instructions:
    1. Preheat the Oven:
      Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish and set aside.
    2. Prepare the Vegetables:
      Bring a large pot of salted water to a boil. Blanch the broccoli and cauliflower florets for 3–4 minutes until tender-crisp. Drain and rinse with cold water to stop the cooking process. Set aside.
    3. Make the Cheese Sauce:
      • In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1–2 minutes until lightly golden.
      • Gradually pour in the warm milk, whisking constantly to prevent lumps. Cook for 3–4 minutes until the sauce thickens.
      • Stir in the cheddar cheese, Parmesan, garlic powder, nutmeg, salt, and pepper. Mix until the cheese is fully melted and the sauce is smooth.
    4. Assemble the Gratin:
      Spread the broccoli and cauliflower florets evenly in the prepared baking dish. Pour the cheese sauce over the top, ensuring all the vegetables are coated.
    5. Prepare the Breadcrumb Topping:
      In a small bowl, mix the panko breadcrumbs with olive oil. Sprinkle the mixture evenly over the gratin.
    6. Bake:
      Bake in the preheated oven for 20–25 minutes, or until the top is golden and the cheese sauce is bubbling.
    7. Garnish and Serve:
      Remove from the oven, let cool for 5 minutes, and sprinkle with fresh parsley before serving.
    8. Pro Tip:
      For added flavor, mix in a pinch of smoked paprika or Dijon mustard into the cheese sauce. This little touch adds a subtle, tangy depth to the dish. Enjoy!
