Why You’ll Love This Cheesy Ground Beef and Rice Casserole

This ground beef and rice casserole is the kind of dinner that makes good use of ingredients you may already have in the kitchen.

The beef and onion are browned together for a savory base, then combined with cooked rice and a creamy sauce. Cheddar cheese melts throughout the casserole and forms a golden, bubbly topping in the oven.

Using cooked rice keeps the preparation straightforward and means you don’t have to wait for rice to cook inside the casserole. You can also assemble the dish ahead of time, making it useful for busy weeknights.

Ingredients You’ll Need

• 1 pound lean ground beef
• 1 small onion, diced
• 2 garlic cloves, minced
• 2 cups cooked white rice
• 1 can (10.5 ounces) cream of mushroom soup or cream of chicken soup
• 1/2 cup milk or beef broth
• 2 cups shredded cheddar cheese, divided
• 1 teaspoon paprika
• Salt and pepper, to taste
• Chopped parsley, optional for garnish

Ingredient Notes

Lean ground beef works well because it provides plenty of savory flavor without leaving too much excess grease in the casserole. Drain any excess fat after browning.

Cooked white rice is important for this recipe. Uncooked rice should not be substituted directly because it will require additional liquid and a different cooking time.

Cream of mushroom soup creates the creamy base, while cream of chicken soup provides an easy alternative with a slightly different flavor.

Sharp cheddar gives the casserole a classic cheesy flavor, but Colby Jack, Monterey Jack, or a cheese blend can also be used.

Milk makes the sauce creamy, while beef broth adds a deeper savory note.

How to Make Cheesy Ground Beef and Rice Casserole

Brown the Beef and Onion

Preheat the oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.

Heat a large skillet over medium heat. Add the ground beef and diced onion.

Cook until the beef is browned and the onion has softened, breaking the meat apart as it cooks. Drain any excess fat.

Add the minced garlic and cook for about 30 seconds, just until fragrant.

Make the Creamy Sauce

In a separate bowl, whisk together the cream of mushroom soup, milk or beef broth, paprika, salt, and pepper.

Mix until the sauce is smooth and evenly combined.

Assemble the Casserole

Add the cooked rice and beef mixture to the prepared baking dish.

Pour in the creamy sauce and add half of the shredded cheddar cheese. Stir gently until the ingredients are evenly distributed.

Spread the mixture into an even layer.

Sprinkle the remaining cheddar over the top.

Bake Until Bubbly

Cover the baking dish with foil and bake for 20 minutes.

Remove the foil and continue baking for another 10 minutes, until the cheese is melted, bubbly, and lightly golden.

For an extra-crispy cheese topping, broil for about 2 minutes at the end. Watch it closely because the cheese can brown quickly under the broiler.

Garnish with chopped parsley if desired and serve hot.

Helpful Recipe Tips

• Use fully cooked rice. Uncooked rice will change the amount of liquid and cooking time needed.
• Drain excess fat from the beef after browning so the casserole doesn’t become greasy.
• Shred cheese from a block when possible for a smooth, even melt.
• Don’t skip covering the casserole during the first part of baking. The foil helps the casserole heat through without drying out.
• Remove the foil for the final 10 minutes so the cheese can brown and become bubbly.
• If broiling the top, stay nearby and watch carefully to prevent the cheese from burning.
• Let the casserole sit for a few minutes before serving if you want cleaner portions.

Easy Variations and Substitutions

Add Vegetables

Stir in peas, carrots, or sautéed mushrooms for extra flavor and texture. If using frozen vegetables, they can generally be added directly to the casserole.

Change the Protein

Ground turkey or ground chicken can replace the ground beef. The finished casserole will have a lighter flavor, so you may want to adjust the seasoning to taste.

Try Different Cheese

Cheddar is a classic choice, but Monterey Jack, Colby Jack, pepper jack, or a combination of cheeses can work well.

Add a Crispy Topping

For extra texture, sprinkle crushed crackers or French fried onions over the cheese before baking.

Make It Gluten-Free

Use a certified gluten-free cream of mushroom soup or prepare your own gluten-free creamy sauce. Check the labels of packaged ingredients if gluten avoidance is important.

Make-Ahead Instructions

The casserole can be assembled up to 24 hours ahead of time.

Prepare the beef mixture, sauce, rice, and cheese as directed, then cover the assembled baking dish and refrigerate it until you’re ready to bake.

Because the casserole will be starting cold from the refrigerator, it may need additional time in the oven to heat completely. Make sure the center is hot before serving.

What to Serve With Ground Beef and Rice Casserole

Because this casserole is creamy and hearty, simple sides work best.

Try serving it with:

• Green salad
• Steamed broccoli
• Roasted green beans
• Sautéed vegetables
• Glazed carrots
• Corn
• Simple cucumber salad

A crisp vegetable side adds freshness and balances the richness of the cheesy casserole.

How to Store Leftovers

Transfer cooled leftovers to an airtight container and refrigerate for up to 4 days.

For longer storage, divide the casserole into individual portions and freeze for up to 2 months.

Thaw frozen portions in the refrigerator before reheating.

How to Reheat

Individual portions can be reheated in the microwave until hot throughout.

For a larger amount, place the casserole in a 350°F oven and heat until warmed through.

If the rice has absorbed some of the creamy sauce during storage, adding a small splash of milk or broth before reheating can help restore moisture.
