Cheesy Ground Beef and Rice Casserole
There’s a particular kind of dinner that doesn’t need explaining — you brown some beef, stir it into rice and a creamy tomato-cheese sauce, spread it in a dish, and let the oven handle the rest. This Cheesy Ground Beef and Rice Casserole is exactly that kind of meal: hearty, saucy, and studded with peas and carrots for a little color and crunch, all pulled together under a layer of melted cheddar. It’s a one-dish dinner built on ingredients most home cooks already have on hand, and it comes together in under an hour with barely any hands-on effort.
This is a familiar American casserole — the kind found in family recipe boxes and church potluck rotations for generations, built on the dependable combination of ground beef, rice, canned tomato sauce, and shredded cheese. It isn’t trying to be trendy; it’s built to be an easy, satisfying dinner on a night when you don’t want to think too hard about what’s for dinner.
What it is: A baked casserole of seasoned ground beef, rice, peas and carrots, and a creamy tomato-cheese sauce, topped with a melted cheddar-sour cream layer. What it tastes like: Savory and cheesy, with a lightly tangy tomato base and a rich, tender topping — closer to a beefy baked rice pilaf than a soup-based casserole. Cooking method: Brown the beef and onion on the stovetop, stir together with rice, sauce, and vegetables, then bake in two stages — an initial uncovered bake followed by a cheesy topping and a second bake. Approximate time: About 15 minutes of prep and 30 minutes in the oven.
Why You’ll Love This Recipe
- One dish, minimal cleanup. Everything simmers together in a single skillet before it goes into the baking dish, so there’s only one pan and one pot to wash.
- Uses ingredients you already have. Ground beef, rice, canned tomato sauce, and cheddar cheese are pantry and fridge staples in most kitchens.
- Kid-approved without being boring. The peas and carrots sneak in vegetables without changing the familiar, cheesy, saucy flavor kids already like.
- Stretches your grocery budget. A pound of ground beef and a cup of dry rice make six generous servings.
- Reheats better than most casseroles. The rice keeps its texture without turning gummy the way potato-based casseroles sometimes do.

Notes
Drain the beef thoroughly after browning, or the sauce turns oily instead of creamy.
Add the sour cream-cheese topping partway through baking (not before) so it melts smoothly instead of separating.
Let it rest 5 minutes before serving so the topping sets.
Freezes well without the topping: freeze the baked beef-and-rice base up to 2 months, thaw overnight, then add a fresh topping before reheating.
Leftovers keep 4 days in the fridge; reheat covered at 350°F or in the microwave in short bursts.
How to Make Cheesy Ground Beef and Rice Casserole
- Preheat the oven to 350°F. Lightly grease a 9×13-inch baking dish.
- Sauté the onion. Melt the butter in a large skillet over medium-high heat. Add the diced onion and cook, stirring occasionally, for 3–4 minutes, until softened and translucent.
- Brown the beef. Add the ground beef and garlic to the skillet. Cook, breaking the beef into crumbles, until no longer pink and the beef reaches an internal temperature of 160°F, about 6–7 minutes. Drain excess fat and return the beef mixture to the skillet.
- Season. Reduce the heat to medium and stir in the oregano, salt, and pepper.
- Build the sauce. Stir in the tomato sauce, chicken broth, cooked rice, frozen peas and carrots, and 1 cup of shredded cheddar. Simmer for 3–4 minutes, stirring occasionally, until the cheese is melted and the mixture is evenly combined.
- Transfer and first bake. Spread the mixture evenly into the prepared baking dish. Bake, uncovered, for 15 minutes.
- Make the topping. While the casserole bakes, stir together the sour cream and the remaining 1 cup of shredded cheddar in a mixing bowl until smooth.
- Top and finish baking. Remove the casserole from the oven, spread the sour cream and cheese mixture evenly over the top, and bake for another 12–15 minutes, until the topping is melted and the edges are bubbling.
- Rest before serving. Let the casserole rest for 5 minutes so the topping sets slightly before serving.
Recipe Tips
- Use day-old rice. Freshly cooked rice keeps releasing steam and moisture, which can make the finished casserole looser than intended.
- Drain the beef well. Leftover grease makes the sauce oily instead of creamy and can cause the casserole to separate as it bakes.
- Add the topping at the right time. Spreading the sour cream mixture on before the first bake causes it to separate and turn grainy instead of melting smoothly.
- Shred your own cheese from a block rather than using pre-shredded bags — it melts smoother into both the sauce and topping.
Common Mistakes to Avoid
- Skipping the fat drain in step 3. Leftover grease pools in the sauce and prevents it from thickening properly.
- Using freshly cooked, hot rice. This adds extra moisture and can leave the casserole looser than intended.
- Adding the sour cream topping before the first bake. It’s best made fresh and added midway through baking, or it can separate and turn grainy.
- Overcrowding the skillet. If your skillet is too small for the full mixture, transfer to a large mixing bowl to combine before spreading it into the baking dish, to avoid uneven mixing and spills.
Variations
- Broccoli cheddar version: Swap the peas and carrots for 2 cups of chopped broccoli florets for a heartier vegetable component.
- Spicy version: Stir a diced jalapeño in with the onion and swap half the cheddar for pepper jack.
- Creamy mushroom version: Replace the tomato sauce and chicken broth with 2 cans of condensed cream of mushroom soup for a richer, less acidic sauce.
- Tex-Mex version: Season the beef with taco seasoning instead of oregano, and top with a Mexican cheese blend and crushed tortilla chips before the final bake.
- French onion topped: Skip the sour cream topping and finish with crispy French fried onions and cheese during the last 5 minutes of baking instead.
What to Serve With It
- A simple green salad with vinaigrette, to balance the richness of the cheese and sour cream
- Steamed broccoli or green beans, for a fresh vegetable side that doesn’t compete with the sauce
- Warm dinner rolls or garlic bread, for scooping up extra sauce
Storage
- Refrigerator: Let the casserole cool to room temperature, then store leftovers in an airtight container for up to 4 days. The sauce will thicken slightly as it chills.
- Freezer: Freeze the baked beef-and-rice base (without the sour cream topping) in an airtight, freezer-safe container for up to 2 months. Sour cream-based toppings can separate when frozen and thawed, so it’s best added fresh.
Reheating
- Oven: Reheat covered in a 350°F oven for 15–20 minutes, until warmed through — this keeps the topping from drying out.
- Microwave: Reheat individual portions in 1-minute intervals until hot throughout; the topping will be softer than lightly set.
- From frozen: Thaw overnight in the refrigerator before reheating, then add a fresh cheese-sour cream topping and warm as directed.
Make Ahead
The beef and rice mixture (through step 5) can be made up to 2 days ahead and refrigerated in an airtight container. When ready to bake, spread it into the dish and continue from step 6, adding a few extra minutes to the first bake since it will be starting cold. Do not assemble the full casserole with the sour cream topping ahead of time — the topping is best made and added fresh just before the final bake, since it can weep liquid if it sits too long.
Frequently Asked Questions
Can I use instant or minute rice instead of regular long-grain rice? Yes, as long as it’s fully cooked before you stir it into the sauce. Instant rice cooks up softer, so the finished texture will be slightly more tender than with regular long-grain rice.
Can I make this without tomato sauce? Yes — two cans of condensed cream of mushroom or cream of chicken soup can replace the tomato sauce and chicken broth for a creamier, non-tomato version.
Why did my casserole turn out watery? This usually happens when the rice was freshly cooked and still releasing moisture, or when the beef wasn’t drained well. Using day-old rice and draining the beef thoroughly both help the sauce hold together.
Can I freeze this casserole? Yes, though it’s best frozen without the sour cream topping, since sour cream can separate when frozen and thawed. Freeze the baked beef-and-rice base for up to 2 months, thaw overnight in the fridge, then make and add a fresh topping before reheating.
How do I know the ground beef is fully cooked? Ground beef is safely cooked when it reaches an internal temperature of 160°F, measured with a food thermometer, and should no longer be pink.
