Gathering your ingredients is the first step towards creating this delightful dish. Each component plays a vital role in building that irresistible creamy, cheesy flavor we all adore.
- 2 large heads of broccoli, about 6 cups florets
- 1/2 cup finely chopped yellow onion
- 1/4 cup unsalted butter, plus 2 tablespoons melted for topping
- 1/4 cup all-purpose flour
- 2 cups milk (whole or 2%)
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon salt, or to taste
- 1/4 teaspoon black pepper, or to taste
- 2 cups shredded sharp cheddar cheese, divided
- 1 cup crushed Ritz crackers or panko breadcrumbs, for topping
How to Make Broccoli Casserole

Let’s walk through creating this heartwarming dish, step by delicious step. You’ll be amazed at how simple it is to bring such a comforting meal to life!
- Prep the Broccoli: Steam or blanch your broccoli florets until they are tender-crisp and vibrant green. Drain them very well and set aside.
- Sauté Aromatics: In a large saucepan or Dutch oven, melt the first 1/4 cup of butter over medium heat. Add the chopped yellow onion and cook gently until it softens and becomes translucent, about 5 minutes.
- Make the Roux: Sprinkle the flour over the softened onions. Stir constantly for 1 minute, letting it cook into a fragrant, pale roux.
- Whisk in Milk: Gradually pour in the milk, whisking continuously to ensure a smooth, lump-free sauce. Continue whisking as the sauce simmers and thickens, which will take about 5-7 minutes.
- Season the Sauce: Remove the pan from the heat. Stir in the garlic powder, onion powder, salt, and black pepper, blending the flavors beautifully.
- Add Cheese: Now, add 1 ½ cups of shredded cheddar cheese to the warm sauce. Stir until the cheese is completely melted and the sauce is wonderfully smooth and creamy.
- Combine Ingredients: Gently fold the prepared broccoli florets into the luscious cheese sauce until every piece is coated in that golden goodness.
- Assemble Casserole: Pour the glorious broccoli and cheese mixture into a lightly greased 9×13 inch baking dish, spreading it evenly.
- Prepare Topping: In a small bowl, combine the crushed Ritz crackers (or panko breadcrumbs) with the 2 tablespoons of melted butter.
- Top and Bake: Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the casserole, followed by your buttery cracker topping.
- Bake to Golden Perfection: Bake in a preheated oven at 375°F (190°C) for 25-30 minutes, or until the casserole is bubbly around the edges and the topping is beautifully golden brown and crispy.
- Rest and Serve: Allow the casserole to rest for 5-10 minutes before serving. This helps the sauce set and makes for easier, more beautiful portions.
Fun Twists & Serving Ideas

This Broccoli Casserole is fantastic as is, but a few simple additions can make it uniquely yours!
- Add Protein: For a heartier main course, stir in some cooked, shredded chicken, diced ham, or even crispy bacon bits right before baking.
- Spice It Up: A tiny pinch of red pepper flakes added to the cheese sauce can introduce a delightful warmth without overpowering the creamy flavors.
- Cheesy Adventures: Don’t be shy to experiment with different cheeses! Gruyere offers a nutty depth, Monterey Jack adds extra meltiness, or a sharp white cheddar provides a more intense tang.
- Vegetable Boost: Toss in some sautéed mushrooms, thinly sliced bell peppers, or even a handful of fresh spinach during the final mixing step for an extra dose of veggies.
- Serving Suggestion: This casserole shines as a side dish alongside roasted chicken, baked salmon, or a festive holiday ham. It’s also incredibly satisfying all on its own for a lighter meal.

FAQ
Q: Can I use frozen broccoli?
A: Yes, absolutely! Just make sure to thaw it completely and drain it very well (perhaps even pat it dry with a clean towel) before adding it to the sauce. This prevents a watery casserole.
Q: How do I store leftovers?
A: Any leftover casserole can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in the oven at 300°F (150°C) until warmed through, or in the microwave for individual servings.
Q: Can I prepare this ahead of time?
A: You can assemble the casserole (without the cracker topping) up to a day in advance. Cover it tightly and refrigerate. Add the topping just before baking. If baking from cold, you might need to add an extra 5-10 minutes to the baking time.
Q: What if I don’t have Ritz crackers?
A: Panko breadcrumbs are a fantastic substitute, offering a similar crunch. Crushed cornflakes also work wonderfully! Just ensure you toss them with melted butter for that golden, rich flavor.
