Ingredients

1/2 to 1 pound ground beef, cooked and drained
1 cup long grain white rice, uncooked
2 cups water
1 cup carrots, sliced
3 tablespoons unsalted butter
1/4 cup onion, minced
1 clove garlic, minced
1/2 cup white button mushrooms, minced
3 tablespoons all-purpose flour
1/2 cup heavy cream
1/2 cup chicken broth
1/4 teaspoon freshly ground black pepper
Salt to taste
9 slices of Cheddar or Colby Jack cheese

Step-by-Step Instructions

Preheat your oven to 350 degrees Fahrenheit and lightly grease an 8×9-inch baking dish with nonstick spray.
In a medium saucepan over medium heat, melt the butter and whisk in the minced onion, garlic, and mushrooms until they are softened and fragrant.
Stir in the flour and cook for approximately 30 to 60 seconds, whisking continually to create a smooth roux.
Slowly pour in the heavy cream and chicken broth, continuing to whisk until the mixture thickens into a creamy, condensed-style sauce.
Season the sauce with salt and black pepper to your preference, then remove it from the heat.
In the prepared baking dish, combine the homemade cream mixture, uncooked long grain white rice, water, cooked ground beef, and sliced carrots. Stir well to ensure all ingredients are evenly distributed.
Bake the casserole uncovered for 90 minutes. Do not worry about covering it; the open air helps create a wonderful texture.
Remove the dish from the oven, layer the cheese slices across the top, and return it to the oven for a few minutes until the cheese is fully melted and golden.

Expert Tips / Pro Tips

For the best results with your Ground Beef Rice Casserole, always use long-grain white rice. This variety holds its structure during the long baking process without becoming mushy or overly sticky. Avoid using Minute Rice or quick-cooking rice unless you significantly reduce the liquid and cooking time according to the package directions. Additionally, do not feel pressured to cover the dish with foil; leaving it uncovered allows the edges to develop a delicious, slightly crispy texture that adds depth to the meal. If you find the rice is not cooking evenly, ensure your oven is maintaining a consistent temperature and that you have distributed the liquid evenly before baking.

This recipe is highly adaptable to what you have in your pantry. If you prefer a shortcut, you can substitute the homemade cream sauce with one can of condensed cream of mushroom soup and skip the sautéing steps. For a different protein, try using ground turkey or shredded chicken. If you want to use brown rice, be sure to add an extra 1/2 cup of water and increase the baking time by about 30 minutes, as brown rice requires more moisture and time to soften. You can also swap the carrots for other vegetables like broccoli florets, peas, or corn to suit your family’s tastes.

Serving Suggestions

While this Ground Beef Rice Casserole is a complete meal on its own, it pairs beautifully with a fresh garden salad or a side of steamed green beans. If you want to lean into the comfort food theme, serve it alongside some warm garlic bread or honey butter rolls. For a bit of brightness and a pop of color, garnish the top with freshly chopped parsley or sliced green onions just before serving.

Store any leftovers in an airtight container in the refrigerator for up to 3 to 4 days. This casserole is also excellent for meal prep as it freezes beautifully for up to 3 months. To freeze, allow the dish to cool completely before transferring it to a freezer-safe container. When you are ready to eat, thaw the casserole in the refrigerator overnight. Reheat in the oven at 325 degrees Fahrenheit for 15 to 20 minutes, or until the center is hot and the cheese is bubbly again. You can also reheat individual portions in the microwave for a quick lunch.

FAQ

Can I make this recipe in a larger dish?

Yes, this recipe can be easily doubled to fit a 9×13-inch baking dish. This is perfect for feeding a large family or for hosting a potluck. Just ensure the rice has enough liquid to cook through completely.

Why didn’t my rice cook all the way?

If the rice is still crunchy after 90 minutes, it is usually because the oven temperature was inconsistent or the wrong type of rice was used. Ensure you are using standard long-grain white rice and that your oven is fully preheated to 350 degrees.

Do I have to use mushrooms?

Not at all. If you are not a fan of mushrooms, you can omit them from the from-scratch sauce or use a different condensed soup, such as cream of chicken or cream of celery, for the quick version.

Is it necessary to brown the beef first?

Yes, you must cook and drain the ground beef before adding it to the casserole. This ensures the meat is fully cooked and prevents the dish from becoming overly greasy.
