Broccoli Cheese Casserole

This broccoli cheese casserole is a cozy, dependable side dish built from tender broccoli, a smooth sharp cheddar sauce, and a crisp golden breadcrumb topping. It is easy enough for a weeknight but comforting enough for a holiday table. The sauce comes together on the stovetop, then the oven finishes the casserole until the edges bubble and the top turns deeply golden. Make it ahead, keep the broccoli well drained, and you will have a creamy bake that serves six with very little last-minute work.

What is broccoli cheese casserole?

Broccoli cheese casserole is a baked vegetable dish in which lightly cooked broccoli is coated in a simple cheese sauce and finished with crumbs. This version uses a flour-thickened milk sauce instead of a canned soup base, so the flavor stays bright and the texture is creamy rather than heavy. The broccoli should remain just tender before baking because it continues cooking in the hot sauce. A sharp cheddar gives the casserole enough character to stand beside roasted meats, while the breadcrumb topping supplies the contrast that makes every spoonful satisfying.

Why you will love this broccoli cheese casserole

The ingredient list is short, the method is forgiving, and the dish can be assembled before dinner. Steaming the florets briefly protects their color and keeps excess water out of the sauce. Shredding cheese from a block helps it melt smoothly, and a quick roux gives the milk enough body to cling to every piece of broccoli. The finished casserole is creamy inside, crisp on top, and flexible enough for a family meal, a potluck, or a holiday side. It also reheats well, making leftovers worth saving.

Ingredients

• 5 cups broccoli florets, fresh or thawed and patted dry
• 2 tbsp butter, melted
• 2 tbsp all-purpose flour
• 2 cups milk, warmed
• 2 cups sharp cheddar cheese, shredded
• 1/2 tsp kosher salt
• 1/4 tsp black pepper
• 1/2 cup breadcrumbs

How to make broccoli cheese casserole

• Heat oven to 375°F and grease a 2-quart baking dish.
• Steam broccoli 3 to 4 minutes until bright green and barely tender; drain well.
• Whisk butter and flour in a saucepan over medium heat, then gradually whisk in milk until smooth and thickened.
• Remove from heat, stir in cheddar, salt, and pepper, and fold in broccoli.
• Transfer to the dish, top with breadcrumbs, and bake 20 to 25 minutes until bubbling and golden.

Serving and timing tips

Let the casserole stand for five minutes before serving so the sauce can settle slightly. It is especially good with roast chicken, baked ham, grilled steak, or a simple green salad. For a larger meal, serve it alongside rice or crusty bread to catch the extra cheese sauce. The recipe yields six side-dish servings. If you are coordinating several dishes, prepare the sauce and broccoli earlier, assemble the dish, and keep it covered in the refrigerator until you are ready to bake.

Storage and reheating

Cool leftovers promptly and refrigerate them in a covered container for up to three days. Reheat individual portions in the microwave in short bursts, or warm the whole casserole in a 350°F oven until hot in the center. The breadcrumb topping is crispest when reheated uncovered. If assembling ahead, cover the unbaked casserole and refrigerate it for up to one day. Add a few minutes to the baking time when starting from cold.

Optional variation

For an optional variation, replace up to half of the cheddar with Monterey Jack for a milder, stretchier sauce. You can also add smoked paprika, garlic powder, or finely chopped cooked bacon. For a vegetarian main dish, stir in drained white beans or cooked rice. Avoid watery vegetables, since excess moisture can thin the sauce and soften the topping.

For the best result, cut the broccoli into evenly sized florets so each piece becomes tender at the same pace. Small florets can become soft before the sauce is ready, while very large pieces may stay firm in the center. A wide, shallow baking dish gives the casserole more golden surface area. If your broccoli was frozen, press it gently between clean towels after thawing. This small step prevents watery pockets and helps the cheese sauce stay thick. Taste the sauce before adding the vegetables and adjust the salt carefully, remembering that cheddar brings its own seasoning. When the casserole is done, look for bubbling around the edges and a lightly browned center rather than relying only on the clock. These visual cues are useful when ovens and baking dishes vary.

Choose a dish that is not too deep so the heat reaches the center evenly. If you are serving children, a mild cheddar blend keeps the flavor gentle without losing the creamy texture. For a more pronounced finish, mix a tablespoon of grated Parmesan into the breadcrumbs. Do not cover the dish while it bakes, because steam will soften the crust. Leftovers can be spooned into a small baking dish and refreshed with a few new crumbs before reheating.
