Ingredients
Core Ingredients
5 cups broccoli florets, roughly chopped
3 cups cooked long-grain white rice
2 cups sharp cheddar cheese, shredded and divided
1 medium onion, finely diced
3 garlic cloves, minced
For the Creamy Cheese Sauce
3 tablespoons butter
3 tablespoons all-purpose flour
2 cups whole milk or half-and-half
½ cup sour cream or Greek yogurt
Seasonings
1 teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon paprika
1 teaspoon kosher salt
½ teaspoon black pepper
Crunchy Topping
½ cup panko breadcrumbs or crushed Ritz crackers
2 tablespoons melted butter
½ cup shredded cheddar cheese
Instructions
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Bring a pot of water to a boil and blanch the broccoli florets for 2 minutes. Drain and set aside.
In a large skillet over medium heat, melt the butter.
Add the diced onion and cook for 4–5 minutes until softened.
Stir in the minced garlic and cook for another 30 seconds.
Sprinkle the flour over the onion mixture and whisk continuously for 1 minute to form a roux.
Gradually add the milk while whisking until smooth.
Cook for 3–4 minutes until the sauce begins to thicken.
Add sour cream, garlic powder, onion powder, paprika, salt, and black pepper.
Stir in 1½ cups of the shredded cheddar cheese and mix until completely melted.
In a large mixing bowl, combine the cooked rice, broccoli, and cheese sauce.
Transfer the mixture to the prepared baking dish and spread evenly.
Top with the remaining cheddar cheese.
In a small bowl, mix the breadcrumbs or crushed crackers with melted butter.
Sprinkle the topping evenly over the casserole.
Bake uncovered for 30–35 minutes or until bubbly and golden brown.
Allow the casserole to rest for 10 minutes before serving.
Tips
Use freshly shredded cheese instead of pre-packaged shredded cheese for a smoother sauce.
Cook the rice slightly firm so it maintains texture after baking.
Avoid overcooking the broccoli during blanching, as it will continue cooking in the oven.
Whisk the sauce continuously to prevent lumps from forming.
Whole milk creates the creamiest texture, but half-and-half adds even more richness.
Allow the casserole to rest before serving so it sets properly.
For extra flavor, use sharp or extra-sharp cheddar cheese.
Mix the topping thoroughly with butter to ensure even browning.
Taste the cheese sauce before assembling and adjust seasoning as needed.
Cover loosely with foil if the topping browns too quickly during baking.
