Cheesy Ground Beef Casserole
Creamy, cheesy, and packed with ground beef and rice — a kid-approved dinner that comes together in one dish.
Ingredients
- 1½ lbs lean ground beef (90/10 or 93/7)
- 1 onion, diced
- 3 cloves garlic, minced
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon smoked paprika
- 1 (10.5 oz) can cream of mushroom soup
- 1 cup sour cream (or plain Greek yogurt)
- ½ cup milk
- 2 cups cooked rice (white or brown)
- 2 cups shredded cheddar cheese, divided
- 1 cup frozen peas and carrots (optional)
- Fresh parsley for garnish
Instructions
- Preheat oven to 375°F. Grease a 9x13-inch baking dish.
- In a large skillet over medium-high heat, cook the ground beef with the diced onion and garlic, breaking it up as it browns, about 6-8 minutes. Drain any excess fat.
- Season the beef with salt, pepper, garlic powder, onion powder, and smoked paprika. Stir to combine.
- In a large bowl, whisk together the cream of mushroom soup, sour cream, and milk until smooth.
- Add the cooked rice, seasoned ground beef, 1½ cups of shredded cheddar cheese, and frozen peas and carrots (if using) to the bowl. Stir until everything is well combined.
- Transfer the mixture to the prepared baking dish and spread it into an even layer.
- Top with the remaining ½ cup of shredded cheddar cheese.
- Bake for 25-30 minutes, until the casserole is hot and bubbly and the cheese on top is melted and golden.
- Let it rest for 5-10 minutes before serving. Garnish with fresh parsley.
Quick Tip
Make it ahead. Assemble the casserole, cover, and refrigerate for up to 24 hours. When ready to bake, add 10-15 minutes to the cook time since you’re starting from cold. Perfect for busy days when you want dinner ready with minimal effort.
Tips
Use lean ground beef. 90/10 or 93/7 lean works best. Higher fat ground beef can make the casserole greasy. If you use 80/20, drain the fat well.
Cook the rice ahead of time. Use leftover rice or make a quick batch while the beef is browning. Day-old rice works great too.
Don’t skip the seasoning. The spices add depth to what could otherwise be a bland casserole. Taste and adjust before baking.
Let it rest. Letting the casserole rest for 5-10 minutes helps it set up and makes it easier to serve.
Add vegetables. The peas and carrots add color and nutrition without changing the flavor. You can also add corn, green beans, or broccoli.
Top with breadcrumbs. For extra texture, mix ½ cup of breadcrumbs with 2 tablespoons of melted butter and sprinkle over the cheese before baking.
Serving Suggestions
This casserole is a complete meal on its own, but here are a few ideas:
- With a side salad — a simple green salad with vinaigrette balances the richness
- With crusty bread — for sopping up any extra sauce
- With roasted vegetables — green beans or roasted broccoli on the side
- With pickles or coleslaw — adds a tangy crunch

Mexican cheesy casserole. Add 1 can of diced green chiles, use pepper jack cheese instead of cheddar, and top with crushed tortilla chips. Serve with salsa and sour cream.

Frequently Asked Questions
Can I use ground turkey instead of beef?
Yes. Ground turkey works well, but it’s leaner and can be drier. Add 1 tablespoon of olive oil when cooking and consider using 85/15 ground turkey for more moisture.
Can I make this casserole ahead of time?
Yes! Assemble the casserole, cover, and refrigerate for up to 24 hours. When ready to bake, add 10-15 minutes to the cook time since you’re starting from cold.
Can I freeze this casserole?
Yes. Freeze for up to 3 months. Thaw overnight in the fridge and reheat in a 350°F oven for 20-25 minutes, until hot and bubbly.
Can I use brown rice instead of white?
Yes. Brown rice works great. Just make sure it’s fully cooked before adding to the casserole. It has more fiber and a nuttier flavor.
How can I add more vegetables?
Add 1 cup of frozen peas and carrots, chopped bell peppers, zucchini, or spinach. They blend right in and add nutrition without changing the flavor.
Why is my casserole dry?
Dry casserole usually means the meat was overcooked or there wasn’t enough sauce. Make sure you use the full amount of sour cream and milk, and don’t overcook the beef before baking.
Why is my casserole watery?
Watery casserole happens when the vegetables release too much liquid. Drain canned vegetables well and make sure the rice isn’t too wet. If using frozen vegetables, don’t thaw them first.
How much protein is in each serving?
Each serving provides approximately 35g of protein from the ground beef, cheese, and Greek yogurt — making this a satisfying, protein-packed meal.
Can I use a different cheese?
Yes. Pepper jack adds a spicy kick, Monterey Jack is mild and creamy, and a Mexican blend works well for a southwestern version.
What’s the best way to reheat leftovers?
Microwave individual portions for 1-2 minutes, or reheat in a 350°F oven for 10-15 minutes. Add a splash of milk if it seems dry.
