Ingredients
  

  • 4 cups broccoli florets fresh or frozen, thawed
  • 2 tablespoons unsalted butter
  • 1 small onion finely chopped
  • 2 cloves garlic minced
  • 2 tablespoons all-purpose flour
  • 1 cup milk whole or 2%
  • 1/2 cup heavy cream
  • 4 ounces cream cheese softened
  • 1/2 cup sour cream
  • 2 cups shredded sharp cheddar cheese plus extra for topping
  • 1/2 cup grated Parmesan cheese optional
  • 1 cup breadcrumbs or panko for topping
  • 1/2 teaspoon salt adjust to taste
  • 1/4 teaspoon black pepper
  • Pinch of nutmeg optional
  • Chopped parsley or chives for garnish

Instructions
 

  • Preheat to 350°F (175°C) and grease a 9×9-inch baking dish with butter or non-stick spray.
  • Bring a pot of salted water to a boil, add broccoli florets for 2 minutes until bright green, then drain and pat dry.
  • In a large skillet over medium heat, melt butter. Add chopped onion and cook 3–4 minutes until translucent, then stir in garlic and cook 1 minute more.
  • Sprinkle in the flour, whisking constantly for 1 minute to remove the raw taste.
  • Slowly whisk in milk and heavy cream until smooth and thickened, then remove from heat and stir in cream cheese, sour cream, cheddar, and Parmesan until creamy.
  • Toss blanched broccoli into the cheese sauce, then spread the mixture into the prepared baking dish.
  • Sprinkle remaining cheddar and breadcrumbs over the casserole, then bake for 20–25 minutes until bubbly and golden.
  • Allow the casserole to rest 5 minutes before serving and garnish with chopped parsley or chives if desired.

Notes

Store leftovers covered in the refrigerator for up to 3 days or freeze for up to 1 month. Thaw before reheating. For extra crisp topping, broil on high for 1–2 minutes.
