Why This Recipe Works
🍳 What You'll Need for This Recipe
Essential tools to make this recipe perfectly
This recipe isn’t just about throwing broccoli and cheese together. It’s about crafting a harmonious balance of flavors and textures. Here’s why it works so well:
- Perfectly Cooked Broccoli: We precook the broccoli to ensure it’s tender-crisp, preventing a soggy casserole. Nobody wants mushy broccoli!
- Rich and Creamy Cheese Sauce: The cheese sauce is made with a roux base, creating a velvety smooth texture that coats the broccoli perfectly. We use a blend of cheddar cheese for that classic flavor and Gruyere for a touch of nutty complexity.
- Crispy Topping: The buttery breadcrumb topping adds a delightful crunch that contrasts beautifully with the creamy sauce and tender broccoli. We’re using panko breadcrumbs for extra crispiness, but regular breadcrumbs will work too.
- Flavor Depth: A touch of Dijon mustard and garlic powder in the cheese sauce adds a subtle depth of flavor that elevates the entire dish.
- Customizable: This recipe is a great base that you can easily adapt to your own preferences. Add bacon, ham, or even mushrooms for a personalized twist.
Ingredients
- Broccoli: 1 large head (about 2 pounds), cut into florets
- Butter: 4 tablespoons, divided
- All-Purpose Flour: 4 tablespoons
- Milk: 3 cups
- Cheddar Cheese: 2 cups, shredded
- Gruyere Cheese: 1 cup, shredded (optional, but highly recommended)
- Dijon Mustard: 1 teaspoon
- Garlic Powder: 1/2 teaspoon
- Salt: 1/2 teaspoon, or to taste
- Black Pepper: 1/4 teaspoon, or to taste
- Panko Breadcrumbs: 1 cup

Instructions
- Preheat Oven and Prepare Baking Dish: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish.
- Cook the Broccoli: Bring a large pot of salted water to a boil. Add the broccoli florets and cook for 3-5 minutes, or until tender-crisp. Drain well and set aside. You can also steam the broccoli if you prefer.
- Make the Cheese Sauce: In a medium saucepan, melt 4 tablespoons of butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux.
- Add Milk Gradually: Gradually whisk in the milk, a little at a time, ensuring there are no lumps. Continue whisking until the sauce is smooth and thickened, about 5-7 minutes.
- Melt the Cheese: Remove the saucepan from the heat. Stir in the cheddar cheese, Gruyere cheese (if using), Dijon mustard, garlic powder, salt, and pepper. Stir until the cheese is melted and the sauce is smooth and creamy.
- Combine Broccoli and Cheese Sauce: Add the cooked broccoli florets to the cheese sauce and gently stir to coat evenly.
- Transfer to Baking Dish: Pour the broccoli and cheese mixture into the prepared baking dish.
- Make the Topping: In a small bowl, melt the remaining 2 tablespoons of butter. Stir in the panko breadcrumbs until evenly coated.
- Sprinkle with Topping: Sprinkle the breadcrumb mixture evenly over the broccoli and cheese casserole.
- Bake: Bake for 20-25 minutes, or until the topping is golden brown and the casserole is bubbly.
- Let it Rest: Let the casserole rest for 5-10 minutes before serving. This allows the sauce to thicken slightly.
Tips for Success
Here are a few tips to ensure your broccoli and cheese casserole turns out perfectly every time:
- Don’t Overcook the Broccoli: Overcooked broccoli will become mushy and unappetizing. Aim for tender-crisp.
- Shred Your Own Cheese: Pre-shredded cheese often contains cellulose, which can prevent it from melting smoothly. Shredding your own cheese ensures a creamier sauce.
- Use a Good Quality Cheese: The quality of the cheese will significantly impact the flavor of the casserole. Choose a good quality cheddar and Gruyere for the best results.
- Adjust Seasoning to Taste: Taste the cheese sauce before adding the broccoli and adjust the seasoning as needed. You may want to add more salt, pepper, or garlic powder.
- Prevent a Soggy Topping: To prevent the breadcrumb topping from becoming soggy, add it just before baking.
- Make Ahead: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Add the breadcrumb topping just before baking. You may need to add a few extra minutes to the baking time if the casserole is cold.
Storage Instructions
Refrigerator: Leftover broccoli and cheese casserole can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat in the oven at 350°F (175°C) until heated through, or microwave in short intervals until warm.
Freezer: While broccoli and cheese casserole can be frozen, the texture may change slightly upon thawing. The cheese sauce can sometimes become grainy. To freeze, let the casserole cool completely, then wrap it tightly in plastic wrap and aluminum foil. Freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating as instructed above. For best results, add the breadcrumb topping after thawing and before baking.
