Description

Cauliflower and Broccoli Gratin is a creamy, cheesy baked side dish that combines tender florets with a rich béchamel sauce and a golden breadcrumb topping. It’s a comforting and flavorful way to enjoy your veggies, perfect for holiday tables or cozy weeknight dinners.


Ingredients

Scale

Vegetables

  • 2 cups cauliflower florets
  • 2 cups broccoli florets

Sauce

  • 2 tablespoons butter
  • 2 tablespoons all-purpose flour
  • 1 1/2 cups whole milk
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon ground nutmeg
  • Salt and black pepper to taste
  • 1 cup shredded sharp cheddar cheese
  • 1/4 cup grated Parmesan cheese

Topping

  • 1/3 cup breadcrumbs
  • 1 tablespoon olive oil or melted butter


Instructions

  1. Preheat and blanch: Preheat the oven to 400°F. Bring a large pot of salted water to a boil and blanch the cauliflower and broccoli florets for 2–3 minutes until just tender. Drain well and set aside.
  2. Make béchamel sauce: In a saucepan, melt butter over medium heat, whisk in flour, and cook for 1–2 minutes to form a roux. Gradually whisk in milk, stirring constantly, and cook until the sauce thickens, about 4–5 minutes. Add garlic powder, nutmeg, salt, and pepper.
  3. Add cheeses: Stir in shredded cheddar and grated Parmesan cheese into the sauce until melted and smooth.
  4. Combine and transfer: Mix the cheese sauce with the drained vegetables, then pour the mixture into a greased baking dish.
  5. Prepare topping: In a small bowl, mix breadcrumbs with olive oil or melted butter. Sprinkle evenly over the top of the vegetable and sauce mixture.
  6. Bake: Bake in the preheated oven for 20–25 minutes until the gratin is bubbly and the breadcrumb topping is golden brown.
  7. Rest and serve: Let the gratin rest for 5 minutes before serving to allow it to set and cool slightly.

Notes

  • Add a pinch of crushed red pepper flakes for a little heat.
  • Swap in Gruyère cheese for a more upscale flavor.
  • This dish can be made ahead and reheated before serving.
