This slow cooker 4-ingredient beef and rice casserole is one of those cozy, hand-me-down recipes that feels like a hug in a bowl. My neighbor shared her grandmother’s version with me years ago, and it quickly became our go-to weeknight meal. Everything cooks together right in the slow cooker—tender ground beef, fluffy rice, and a creamy, golden brown sauce—so it’s perfect for busy days when you still want that homemade comfort on the table.
Ladle the hot beef and rice casserole into bowls and top with a little shredded cheese or sliced green onions if you like. It’s hearty enough to stand on its own, but it pairs nicely with a simple green salad, steamed broccoli, or a side of buttered peas to add some color and crunch. Warm dinner rolls or garlic toast are great for scooping up every last bit of the creamy sauce, and a side of applesauce or sliced fresh fruit keeps the meal kid-friendly and balanced.
Slow Cooker 4-Ingredient Beef and Rice Casserole
Servings: 6

Ingredients
1 1/2 pounds ground beef (85–90% lean)
1 1/2 cups long-grain white rice, uncooked
2 cans (10.5 ounces each) cream of mushroom soup
3 cups beef broth (low sodium, divided use: 1 cup for browning, 2 cups for slow cooker)
1 teaspoon kosher salt (or to taste, optional)
1/2 teaspoon black pepper (optional)
1 teaspoon dried onion powder or garlic powder (optional, for extra flavor)
Nonstick cooking spray or 1 teaspoon oil (for skillet, optional)
Directions
Lightly spray the inside of a 5- to 6-quart slow cooker with nonstick cooking spray to help with easy cleanup.
In a large skillet over medium-high heat, add a light coating of oil if needed, then add the ground beef. Cook, breaking it up with a spoon, until it is no longer pink, about 6–8 minutes. Drain off any excess grease carefully.
Season the cooked beef with salt, pepper, and onion or garlic powder if using. Pour in about 1 cup of the beef broth to deglaze the skillet, scraping up any browned bits from the bottom for extra flavor.
Transfer the seasoned ground beef and broth mixture to the prepared slow cooker, spreading it out in an even layer.
Sprinkle the uncooked long-grain white rice evenly over the beef in the slow cooker. Do not stir; just spread it gently so it covers the top.
In a medium bowl, whisk together the cream of mushroom soup and the remaining 2 cups of beef broth until smooth and creamy.
Pour the soup mixture evenly over the rice and beef in the slow cooker, making sure all of the rice is moistened. Gently press down any dry rice with the back of a spoon, but avoid stirring so the rice can cook evenly.
Cover the slow cooker with the lid and cook on LOW for 4–5 hours, or until the rice is tender and has absorbed most of the liquid, and the mixture is thick, creamy, and bubbling around the edges.
Once done, give the casserole a gentle stir from top to bottom to mix the beef, rice, and sauce together into a creamy, golden brown mixture. Taste and adjust seasoning with a little more salt and pepper if needed.
Serve hot straight from the slow cooker while it’s still steamy. The casserole will thicken slightly as it stands, which makes it even cozier and perfect for scooping into bowls.
Variations & Tips
For picky eaters, you can keep the base recipe as-is and simply offer toppings at the table: shredded cheddar, Parmesan, chopped parsley, or a little ketchup on the side for kids who like to dip. If your family likes a bit of extra flavor, stir in 1 teaspoon of smoked paprika or Italian seasoning with the ground beef, or use cream of chicken or cream of celery soup instead of mushroom for a milder taste. To sneak in veggies, layer 1–2 cups of frozen peas and carrots or corn on top of the beef before adding the rice; they’ll cook right along with everything else. For a cheesier version, sprinkle 1–2 cups of shredded cheese over the top during the last 10–15 minutes of cooking and cover until melted. You can also swap part of the beef broth for milk or half-and-half (up to 1 cup) to make the sauce even creamier, but keep at least 2 cups of broth for proper rice cooking. Food safety tips: Always cook the ground beef thoroughly in a skillet before adding it to the slow cooker; do not put raw ground beef in with the rice, as it may not heat evenly. Make sure the casserole is hot and bubbly and the rice is fully tender before serving. Refrigerate leftovers within 2 hours in shallow containers, and reheat until steaming hot before eating. If using low-sodium broth, adjust salt only after cooking so you don’t accidentally oversalt the dish.
