Ingredients You’ll Need

These ingredients come together in a beautiful way to build layers of flavor. I like using fresh broccoli because it holds its texture during cooking, and sharp cheddar gives just the right kick of cheesiness. Simple pantry staples like flour and butter help create that silky sauce that binds the whole casserole together.

• Broccoli: Fresh crowns with stems are key—don’t toss those stems, they add great texture once sliced and cooked.
• Butter: Split between melting in the sauce and toasting the breadcrumbs, making everything rich and golden.
• Panko Breadcrumbs: Gives a crispy, light topping that contrasts beautifully with the creamy sauce.
• All-purpose Flour: This helps thicken the cheese sauce perfectly without lumps.
• Whole Milk: Adds creaminess and helps make the sauce silky.
• Sharp Cheddar Cheese: I like a cheese with punch—don’t skimp here, it’s what makes the dish sing.
• Kosher or Sea Salt: For seasoning both the broccoli water and at the assembly stage to enhance all flavors.
• Freshly Ground Black Pepper: Adds a subtle touch of heat and depth to the creamy sauce.

Variations

This Broccoli Cheese Casserole Recipe is a wonderful canvas for your personal tweaks—whether you want to kick up the spice, make it gluten-free, or add more veggies. I’ve played around with a few versions and each one has been a hit in my kitchen.

• Add Bacon: I’ve sprinkled crispy bacon bits on top for an irresistible smoky crunch—definitely a crowd-pleaser.
• Use Different Cheeses: Mixing sharp cheddar with Gruyère or mozzarella can take this casserole in a whole new direction flavor-wise.
• Gluten-Free: Substitute the all-purpose flour with a gluten-free blend and use gluten-free breadcrumbs—just as tasty!
• Extra Veggies: Throw in some sautéed mushrooms or chopped bell peppers next to the broccoli for a colorful twist.

How to Make Broccoli Cheese Casserole Recipe

Step 1: Preparing and Cooking the Broccoli

Start by cutting the broccoli heads into florets—aim for about 10 cups. Don’t toss the stems! Trim and peel their tough outer layer, then slice them into coins. Boil a large pot of salted water and cook the broccoli stems first for about 3 minutes—they need a little longer to get tender. Then add the florets and cook another 3 to 4 minutes until they’re vibrant green and just tender enough to pierce with a fork. Immediately drain and give them a quick ice bath with cold water to stop cooking—this keeps their color bright and texture perfect. Lay them out on a tea towel to drain while you prep the rest.

Step 2: Toast the Breadcrumbs

Using the same pot (after a quick rinse), melt 1 tablespoon of butter over medium heat. Once it’s foaming, toss in the panko breadcrumbs and stir frequently. It takes just 2 to 3 minutes for them to become golden and wonderfully toasted. Take care not to burn them—they go from golden to burnt quickly! Scrape breadcrumbs out into a bowl and wipe the pot clean for the sauce.

Step 3: Make the Cheese Sauce

In the same pot, melt the remaining 2 tablespoons of butter over medium-low heat. Stir in the flour and whisk until it forms a smooth paste—a roux—cooking it just about a minute until it smells nutty and golden. Now slowly whisk in the milk to avoid lumps. Bring the mixture to a gentle simmer and stir often as it thickens, about 2 to 3 minutes. Once it’s thick enough to coat the back of your spoon, remove from heat and stir in 1 cup of shredded sharp cheddar cheese until the sauce is smooth and perfectly cheesy.

Step 4: Assemble and Bake the Casserole

Butter a 9×13-inch casserole dish and spread the broccoli evenly inside. I always salt and pepper the broccoli generously here because it helps season every layer. Pour the creamy cheese sauce over the broccoli, then sprinkle the remaining shredded cheddar on top. Finish by scattering your toasted breadcrumbs evenly for that crave-worthy crunch. Bake at 400°F for about 20 minutes, or until the cheese has melted and the top is golden brown. Let it rest for 5 to 10 minutes so it sets beautifully before serving.

How to Serve Broccoli Cheese Casserole Recipe

Garnishes

I love topping my casserole with a sprinkle of chopped fresh parsley or chives. It adds a pop of color and a fresh herbal note that brightens the rich cheese flavor. Sometimes, a little drizzle of good olive oil right before serving takes it up a notch.

Side Dishes

This casserole pairs beautifully with roasted chicken or grilled sausages. For a vegetarian meal, I like serving it with a crisp green salad tossed with a tangy vinaigrette and some crusty bread to soak up any extra sauce.

Creative Ways to Present

For special occasions, I sometimes serve this casserole in individual ramekins to make it feel extra fancy. You can also layer it with slices of cooked potatoes or add a layer of caramelized onions for a richer twist that guests always rave about.

Make Ahead and Storage

Storing Leftovers

Once your casserole has cooled completely, store leftovers in an airtight container in the refrigerator. I find it lasts well for 2 to 3 days and still tastes delicious—just reheat gently.

Freezing

I’ve frozen this casserole several times with great results. Just assemble and bake, then cool completely and freeze in a resealable container. To enjoy later, thaw overnight in the fridge and reheat in the oven until warmed through.

Reheating

Reheat leftovers in a 350°F oven, covered with foil to prevent drying out, for about 15 to 20 minutes. You’ll still get a melty cheese experience, and the breadcrumbs re-crisp nicely if uncovered for the last few minutes.
