The Cheesy Ground Beef and Rice Casserole is a comforting, savory dish that brings together hearty ground beef, tender rice, and gooey melted cheddar cheese in one convenient, easy-to-make meal. This casserole is perfect for busy weeknights when you want a filling, delicious meal without a lot of hassle. The beauty of this dish lies in its simplicity, as it requires only a handful of pantry staples and a few fresh ingredients.

As a one-pan meal, it not only reduces cleanup but also ensures that the flavors meld together beautifully as the rice absorbs the rich beef broth, seasoned beef, and creamy mushroom mixture.

With the ability to add vegetables, switch up the cheese, or use different types of rice, it’s incredibly versatile and adaptable to any taste preference.

Ingredients Breakdown and Preparation

1. Ground Beef (85% lean)

Using 85% lean ground beef strikes the perfect balance between flavor and texture in casseroles. The 15% fat content provides just enough richness to keep the dish moist without becoming overly greasy, which is crucial when cooking a layered meal like this casserole. Leaner beef (e.g., 90% or higher) can result in a drier texture. If you’re looking for a leaner or alternative protein, ground turkey can be a great substitute, offering a lighter flavor profile. For plant-based options, crumbled tofu or plant-based meat alternatives can easily replace the ground beef while still absorbing the flavors of the dish.

2. Seasoning and Flavors

Italian seasoning is key to elevating the flavor of this dish. A blend of herbs such as oregano, basil, and thyme, it complements the richness of the beef and cheese while adding depth to the casserole. Salt and pepper are essential for balancing the flavors—salt enhances the savory components, while pepper adds a mild kick.

3. Butter, Onions, and Garlic

Sautéing onions and garlic in butter creates a flavorful base for the casserole. Butter adds richness and smoothness, while the onions and garlic develop a sweet, aromatic flavor that deepens as they cook. This combination ensures that the beef and rice mixture isn’t bland.

4. Beef Broth and Rice

Cooking the rice in beef broth instead of water infuses it with savory, beefy flavor, adding depth to every bite. Long grain white rice is ideal for casseroles because it maintains its structure during cooking and absorbs flavors without becoming mushy. Instant rice, on the other hand, can easily overcook and lose texture.

5. Mushrooms

Button mushrooms add a subtle earthy flavor and meaty texture to the dish, complementing the richness of the beef and cheese. To prepare, clean them gently with a damp cloth to avoid waterlogging. Cremini or portobello mushrooms can be used for a stronger, more robust flavor.

6. Cream of Mushroom Soup, Milk, and Sour Cream

These ingredients create the creamy base of the casserole, keeping the dish moist and flavorful. The cream of mushroom soup adds a velvety texture, while milk and sour cream provide richness and tang. Balancing these creamy components ensures the dish isn’t too heavy.

7. Cheddar Cheese

Shredded cheddar cheese adds the perfect cheesy finish to the casserole. Sharp cheddar offers a more pronounced flavor, while mild cheddar brings a smoother, creamier texture. For variety, you could substitute mozzarella for a stretchier texture or Colby-Jack for a milder, buttery flavor.

Step-by-Step Cooking Process

1. Preheat the Oven

Preheating the oven is an essential step to ensure even cooking throughout the casserole. When you place the dish in a fully heated oven, the food starts cooking at the correct temperature right away. This prevents uneven cooking, where the edges might overcook while the center remains undercooked. Set the oven to 350°F (175°C) to create the perfect environment for the casserole to bake evenly and for the cheese to melt properly.

2. Brown the Ground Beef

In a large pot or skillet, heat the stove to medium-high and add the ground beef. Break the beef into small chunks using a wooden spoon or spatula as it cooks. This helps ensure that the beef cooks evenly and doesn’t clump together. Season with Italian seasoning, salt, and pepper. Cook the beef until it’s fully browned and no longer pink, which should take about 5-7 minutes. It’s crucial not to overcook the beef, as that can make it dry. Once browned, drain any excess grease to avoid making the casserole oily, then set the beef aside, covered.

3. Sauté Onions and Garlic

Using the same pot, melt 2 tablespoons of butter over medium heat. Add the diced onions and sauté them for about 5 minutes, stirring occasionally. The goal is to soften the onions until they become translucent but not browned. Onions and garlic are foundational aromatics that develop deeper flavors when sautéed properly. After the onions have softened, add the minced garlic and sauté for about 1 minute. Garlic burns easily, so keep an eye on it, stirring constantly to release its flavor without allowing it to become bitter.

4. Cook the Rice

Once the onions and garlic are softened, it’s time to cook the rice. Pour in 2 ½ cups of beef broth and bring the mixture to a boil over medium-high heat. The beef broth adds a rich, savory flavor to the rice, enhancing the overall taste of the casserole. After reaching a boil, stir in 1 ¼ cups of uncooked long grain white rice. Reduce the heat to low, cover the pot with a tight-fitting lid, and let it simmer for about 10 minutes.

After 10 minutes, add the sliced button mushrooms and stir them into the rice mixture. Cover the pot again and continue cooking for another 5-10 minutes until the rice is tender and most of the liquid has been absorbed. The exact timing may vary depending on the brand and type of rice you use, so it’s important to check the rice package instructions for specific cooking times. Once the rice is done, it should be tender but not mushy, with the grains separate and not overcooked.

5. Let the Rice Rest

After the rice has finished cooking, turn off the heat and leave the pot covered for 10 minutes. This resting period allows the rice to absorb any remaining broth and ensures that the grains stay fluffy and firm. Resting also helps to integrate the flavors, creating a more cohesive dish.

6. Combine the Ingredients

Once the rice has rested, it’s time to combine all the ingredients. Stir the browned ground beef back into the rice mixture. Then, add one can (10.5 oz) of cream of mushroom soup, ½ cup of milk, ½ cup of sour cream, and 1 cup of shredded cheddar cheese. Mix everything together thoroughly to ensure that the creamy ingredients coat the beef and rice evenly.

This step is critical for achieving a cohesive, well-balanced casserole. The cream of mushroom soup, milk, and sour cream provide moisture and creaminess, preventing the casserole from drying out during baking. The cheese adds a rich, savory flavor that complements the beef and mushrooms. Make sure to stir well so that the ingredients are evenly distributed throughout the mixture.

7. Assemble the Casserole

Lightly grease a 9×13-inch baking dish to prevent sticking. Transfer the beef and rice mixture into the prepared baking dish, spreading it out evenly with a spatula to ensure a uniform layer. A well-spread mixture ensures that every bite of the casserole will have a balanced portion of beef, rice, mushrooms, and cheese. Once the mixture is evenly spread, sprinkle the remaining 1 cup of shredded cheddar cheese over the top of the casserole. The cheese topping will melt beautifully in the oven, creating a golden, bubbly layer.

8. Bake the Casserole

Cover the casserole dish with aluminum foil to prevent the cheese from over-browning while the ingredients heat through. Place the covered dish in the preheated oven and bake for 20 minutes. During this time, the cheese will melt, and the flavors of the beef, rice, and mushrooms will meld together. After 20 minutes, remove the foil and bake for an additional 5-10 minutes, or until the cheese on top is bubbly and golden. The casserole is ready when the cheese has fully melted and the edges are slightly crisp.

9. Serve

Once the casserole is out of the oven, let it rest for 5-10 minutes before serving. This brief resting time allows the casserole to set, making it easier to slice and serve without falling apart. For added flavor, garnish with fresh herbs like parsley or a dash of hot sauce for a spicy kick.

Tips and Variations

Customizing the Recipe

One of the best things about this cheesy ground beef and rice casserole is how easy it is to customize based on your preferences or what you have on hand.

Adding Vegetables: For extra nutrition and color, consider adding vegetables like peas, bell peppers, spinach, or corn. These ingredients can be stirred into the rice mixture after cooking. Bell peppers and peas add sweetness and crunch, while spinach and corn bring more texture and a pop of vibrant color.
Spicing It Up: If you prefer a bit of heat, add crushed red pepper flakes or a splash of hot sauce to the mixture before baking. This will give the dish a subtle, spicy kick. For even more spice, consider adding diced jalapeños or using pepper jack cheese instead of cheddar.
Swapping Proteins: For a different flavor profile, you can substitute the ground beef with ground chicken, turkey, or pork. Ground turkey and chicken provide a leaner option, while pork adds a slightly sweeter and richer taste to the casserole.

Making It Healthier

There are several simple substitutions you can make to increase the nutritional value of this dish.

Low-Fat Options: Use low-fat cheese, sour cream, and milk to reduce the calorie content while still maintaining the creamy texture and cheesy goodness of the casserole.
Using Brown Rice: Swap out white rice for brown rice to add more fiber and nutrients. Keep in mind that brown rice takes longer to cook, so adjust the cooking time and liquid accordingly.

More Vegetables: Bulk up the dish with more vegetables like zucchini, carrots, or broccoli for added vitamins and minerals.
