Description

A creamy and cheesy broccoli cauliflower casserole featuring a rich sauce and crunchy breadcrumb topping, perfect for a comforting side dish that serves a crowd.


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 oven to 350° Fahrenheit and heat a large pot of water. Boil or steam the broccoli and cauliflower pieces for 4-5 minutes until they are semi-tender. Drain and place them in a lightly greased 9×13 inch baking pan.
  2. Make Cream Sauce: In a large skillet, melt the butter over medium heat. Add the diced onion and minced garlic, cooking until tender and fragrant, about 4-5 minutes. Whisk in the flour and cook until thickened. Gradually whisk in the milk, stirring continuously until the mixture is smooth and creamy. Season with salt, black pepper, and fresh thyme.
  3. Combine and Add Cheese: Pour the creamy sauce evenly over the broccoli and cauliflower pieces in the baking pan. Sprinkle shredded sharp cheddar cheese and parmesan cheese on top.
  4. Prepare and Add Crumb Topping: In a small bowl, mix the plain bread crumbs with garlic powder and melted butter. Spread this crumb mixture evenly over the casserole.
  5. Bake the Casserole: Bake the casserole at 350° Fahrenheit for 20 minutes until the topping is golden brown and the vegetables are tender. Remove from oven and let rest briefly before serving.

Notes

  • Use fresh broccoli and cauliflower for the best texture and flavor.
  • This casserole can be prepared up to 48 hours ahead of time and refrigerated; bake until bubbly in the center before serving.
  • The original recipe included chicken broth in the cream sauce, but it was removed to create a thicker sauce. If your sauce is too thick, add a little more milk to reach your desired consistency.
  • For a crispier topping, you can toast the bread crumbs lightly before mixing with butter and garlic powder.
