Why You’ll Love This Recipe
- Homemade cheese sauce: Butter, flour, milk, broth, and cheddar create a creamy sauce without canned soup.
- Easy preparation: Using cooked rice makes assembly quick and straightforward.
- Flexible serving options: Enjoy it as a vegetarian main course or serve smaller portions alongside dinner.
- Make-ahead friendly: Prepare the components ahead and assemble the casserole when needed.
- Golden topping: Buttered breadcrumbs and melted cheddar add a lightly crisp finish.
Ingredients You’ll Need
- Cooked long-grain white rice: Three cups of cooked rice provide the hearty base. Long-grain rice helps the grains stay separate instead of becoming too sticky.
- Fresh broccoli: Chopped florets add color, texture, and a fresh vegetable component. Blanching them briefly helps them retain some firmness.
- Butter, onion, and garlic: These ingredients build the savory base of the cheese sauce and add depth to the casserole.
- All-purpose flour: Flour thickens the milk and vegetable broth into a smooth sauce that coats the rice and broccoli.
- Whole milk and vegetable broth: Milk provides creaminess, while vegetable broth adds savory flavor.
Chef’s Tip: Drain the broccoli thoroughly after blanching and let the cooked rice cool before mixing everything together. Excess moisture can make the casserole loose instead of creamy.

Equipment
- 9 × 13-inch baking dish
- Medium saucepan
- Large mixing bowl
- Whisk
- Wooden spoon or spatula
- Measuring cups and spoons
- Sharp knife
- Cutting board
Ingredients
- 3 cups cooked long-grain white rice
- 3 cups fresh broccoli florets chopped
- 2 tablespoons unsalted butter
- ½ cup finely chopped yellow onion
- 2 cloves garlic minced
- 2 tablespoons all-purpose flour
- 1 cup whole milk
- ½ cup vegetable broth
- ½ cup sour cream
- 2 cups shredded sharp cheddar cheese divided
- ¼ teaspoon paprika
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ cup breadcrumbs
- 1 tablespoon melted butter for the topping
Instructions
- Prepare the Broccoli: Preheat the oven to 375°F (190°C). Bring a saucepan of salted water to a boil and add the broccoli florets. Cook for 2–3 minutes until bright green and slightly tender. Drain well and set aside.
- Cook the Aromatics: Melt 2 tablespoons of butter in a medium saucepan over medium heat. Add the chopped onion and cook for 3–4 minutes until softened. Stir in the minced garlic and cook for another 30 seconds until fragrant.
- Make the Creamy Sauce: Sprinkle the flour over the onion mixture and stir continuously for about 1 minute. Gradually whisk in the milk and vegetable broth, making sure no lumps form. Cook for 3–5 minutes until the sauce thickens slightly.
- Add the Cheese: Reduce the heat to low. Stir in the sour cream, 1½ cups of shredded cheddar cheese, paprika, salt, and black pepper. Mix until the cheese melts and the sauce becomes smooth and creamy.
- Combine the Rice and Broccoli: Place the cooked rice and drained broccoli in a large mixing bowl. Pour the cheese sauce over the mixture and fold gently until everything is evenly coated.
- Transfer to the Baking Dish: Lightly grease a 9 × 13-inch baking dish. Spoon the broccoli and rice mixture into the dish and spread it into an even layer. Sprinkle the remaining ½ cup cheddar cheese over the top.
- Prepare the Topping: Combine the breadcrumbs with 1 tablespoon of melted butter. Scatter the mixture evenly over the cheese layer to create a lightly crisp topping.
- Bake Until Golden: Bake uncovered for 25–30 minutes, until the casserole is hot and bubbling around the edges and the breadcrumb topping is golden. Let it rest for 5–10 minutes before serving.
Notes
- Use fully cooked and cooled rice before combining it with the sauce.
- Long-grain white rice works well because the grains stay separate in the casserole.
- Drain the broccoli thoroughly to prevent excess moisture from thinning the cheese sauce.
- Freshly shredded cheddar melts more smoothly than pre-shredded cheese.
- For a shortcut, frozen broccoli can be used. Thaw it completely and drain well before adding.
