Preparation Phase & Tools to Use
Before diving into the preparation of your casserole, it’s essential to set up your kitchen workspace to ensure a smooth cooking experience. Start by preheating your oven to 350°F (175°C) and grease a 9×13-inch baking dish with some butter or cooking spray to prevent sticking. Next, gather all your ingredients and tools. You will need a large mixing bowl, a skillet for sautéing, a pot for cooking the rice if you are not using leftovers, and a steamer or pot for blanching the broccoli.
Having everything organized will help streamline the process. Ensure your broccoli is cut into small florets for even cooking, and prepare your rice as per the instructions if you haven’t already done so. The combination of these fresh ingredients with the right tools sets you up for successful cooking!

Ingredients
- 2 cups cooked white rice
- 3 cups broccoli florets
- 1 can (10.5 oz) cream of mushroom soup
- 1/2 cup sour cream
- 1/2 cup milk
- 2 cups shredded cheddar cheese
- 1/4 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 2 tablespoons unsalted butter
- 1/4 cup chopped yellow onion
Instructions
Step 1: Preheat and Prepare Baking Dish
Start by preheating your oven to 350°F (175°C). Prepare your baking dish by greasing it with a little butter or cooking spray to prevent the casserole from sticking. This step ensures that you can easily serve the portions without any mess!
Step 2: Cook the Rice
If you haven’t already cooked your rice, do so according to the package instructions. The rice is the base of your casserole, so ensuring it’s perfectly cooked will give you the best results for texture and flavor.
Step 3: Steam the Broccoli
While the rice is cooking, steam your broccoli florets until they are just tender. This should only take a few minutes. Make sure to drain the broccoli well to avoid excess water that could make the casserole soggy.
Step 4: Sauté the Onion
In a skillet, melt the unsalted butter over medium heat. Add in the chopped yellow onion and sauté until they turn soft and translucent. This process enhances the flavor, creating a delicious base for your casserole.
Step 5: Mix the Casserole Base
In a large mixing bowl, combine the cream of mushroom soup, sour cream, milk, garlic powder, onion powder, salt, and black pepper. Mix these ingredients until they are well incorporated. This creamy mixture will bind all the other components together beautifully.
Step 6: Combine Ingredients
Once your creamy mixture is ready, stir in 1½ cups of shredded cheddar cheese. Next, gently fold in the cooked rice, steamed broccoli, and sautéed onion until everything is evenly coated with the sauce. This ensures that every bite of your casserole is packed with flavor.
Step 7: Spread and Top
Transfer the mixture into your prepared baking dish, spreading it out evenly. Top it with the remaining ½ cup of shredded cheddar cheese to get that beautifully bubbly and cheesy crust on top.
Step 8: Bake
Cover the casserole with aluminum foil and bake in the preheated oven for 25 minutes. After that, remove the cover and bake for an additional 10-15 minutes until the cheese is melted and bubbly. The golden brown topping adds a lovely texture to the finished dish!
Step 9: Serve
Once done, let the casserole rest for 5-10 minutes before serving. This resting time allows the dish to set, making it easier to serve into neat portions.
