Ingredients

Scale

Vegetables

  • 4 cups broccoli, washed and cut into 1 inch pieces
  • 3 cups cauliflower, washed and cut into 1 inch pieces

Cream Sauce

  • ¼ cup butter
  • 1 cup onion, diced
  • 4 cloves garlic, minced
  • ¼ cup all purpose flour
  • 2 cups milk
  • 1 tbsp thyme, fresh
  • 2 tsp salt
  • 1 tsp black pepper
  • 2 cups sharp cheddar cheese, shredded
  • ⅓ cup parmesan cheese, shredded

Crumb Topping

  • 1½ cups plain bread crumbs
  • 2 tsp garlic powder
  • 2 tbsp butter, melted


Instructions

  1. Preheat and Prepare Vegetables. Preheat the oven to 350°F (177°C) and bring a large pot of water to a boil while preparing the broccoli and cauliflower by washing and cutting into 1 inch pieces.
  2. Cook Vegetables. Boil or steam the broccoli and cauliflower for 5 minutes until they are semi-tender, then drain them well and transfer into a lightly greased 9x13 inch baking dish.
  3. Make the Cream Sauce. In a large skillet, melt ¼ cup butter over medium heat and sauté the diced onion and minced garlic until tender and fragrant, about 4-5 minutes. Whisk in the flour and cook until thickened. Gradually whisk in milk, stirring constantly until the sauce is smooth and creamy. Season with salt, pepper, and fresh thyme.
  4. Combine and Cheese. Pour the creamy sauce evenly over the broccoli and cauliflower in the baking dish. Sprinkle the shredded sharp cheddar and parmesan cheeses over the top.
  5. Prepare Crumb Topping. In a small bowl, combine the plain bread crumbs, garlic powder, and melted butter. Evenly spread this crumb mixture over the cheese layer in the casserole.
  6. Bake. Bake the casserole in the preheated oven at 350°F for 20 minutes, or until the top is golden brown and the vegetables are fully tender.

Notes

  • Use fresh broccoli and cauliflower for the best texture and flavor.
  • This casserole can be prepared up to 48 hours ahead of time; store it covered in the refrigerator and bake just before serving until bubbly in the center.
  • If the cream sauce seems too thick without chicken broth, add a splash more milk to reach the desired consistency.
  • For a crispier topping, broil the casserole for 2-3 minutes at the end of baking, watching carefully to avoid burning.
