Family dinners don’t have to be a flurry of pots, pans, and last-minute running to the grocery store. This Cheesy Ground Beef and Rice Casserole delivers everything you love about a hearty, home-cooked meal—all in one dish. Tender ground beef sautéed with onion and garlic, creamy soup and sour cream, fluffy rice, and a generous layer of melted cheddar come together to satisfy even the pickiest appetites. With minimal prep and an easy bake in the oven, you’ll have a bubbling, golden-topped casserole on the table in under an hour—perfect for busy weeknights or a relaxed weekend supper.

What makes this casserole such a winner is its balance of familiar flavors and effortless assembly. You begin by browning lean ground beef with sweet onion until the meat develops a deep, savory crust and the onions turn translucent. A quick stir of garlic, paprika, salt, and pepper wakes up the aromatic base. In a large mixing bowl, you marry that beefy goodness with cooked rice, cream of mushroom or cheddar soup, a dollop of sour cream, a splash of milk, and most of the cheddar cheese. Frozen peas or corn can be stirred in for an extra pop of color and nutrition, but the recipe shines even without them.

Once assembled, the casserole goes into a lightly greased 9×13-inch baking dish, crowned with the remaining cheddar. As it bakes at 375°F, the cheese melts into a golden blanket while the sauce bubbles around the edges, melding flavors and creating an irresistible aroma that draws everyone to the kitchen. A brief rest after baking allows the sauce to thicken slightly, so you can cut neat squares that hold their shape.

This dish is endlessly adaptable. Swap brown rice for white, use cream of chicken soup instead of mushroom, or stir in diced bell peppers or mushrooms when you sauté the onion. Ground turkey or chicken make leaner alternatives to beef, and a sprinkle of chopped fresh parsley or chives adds a bright finish. Whether you serve it alongside a crisp green salad, steamed broccoli, or warm dinner rolls, this Cheesy Ground Beef and Rice Casserole has everything you need for a comforting, crowd-pleasing meal.

In Part 1, we’ll prepare the oven and baking dish, brown the meat and aromatics, and assemble the creamy filling. By the end of these steps, your casserole will be ready to top with cheese and slide into the oven for that satisfying bake. Let’s get started.

STEPS

Preheat and prepare
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with nonstick spray or a thin coating of butter. This ensures the casserole slides out cleanly and prevents cheese from sticking to the pan.

Brown the beef and onion
In a large skillet over medium heat, add 1 pound of ground beef and 1 diced small onion. Break up the meat with a wooden spoon and cook, stirring occasionally, until the beef is no longer pink and the onion is soft—about 6 to 8 minutes. Transfer the mixture to a bowl and drain off any excess fat.

Sauté garlic and seasonings
Wipe out excess oil if necessary, then return the skillet to medium heat. Add 2 cloves of minced garlic, ½ teaspoon salt, ½ teaspoon black pepper, and 1 teaspoon paprika. Cook, stirring constantly, for 1 to 2 minutes until the garlic is fragrant and the spices bloom in the fat.

Mix the creamy filling
In a large mixing bowl, combine the sautéed beef-onion-garlic mixture with 2 cups of cooked white or brown rice, 1 can (10.5 ounces) of cream of mushroom or cream of cheddar soup, ½ cup sour cream, ½ cup milk, 1 cup of shredded cheddar cheese, and ½ teaspoon dried parsley or thyme. If desired, stir in ½ cup of frozen peas or corn for extra color and nutrients. Mix gently until all ingredients are thoroughly coated in a creamy sauce.

Cheesy Ground Beef and Rice Casserole: Baking & Customizations

With your creamy, beefy filling tucked into the prepared baking dish, the final steps are simple: blanket it with cheese, bake until bubbling and golden, then let it rest before serving. In this section, you’ll learn exactly how long to bake, how to tell when it’s done, and discover easy variations that let you tailor the casserole to your family’s tastes.

STEPS

Spread into the dish
Spoon the beef–rice mixture evenly into the greased 9×13-inch baking dish. Use the back of your spatula to level the top so that every portion bakes uniformly.

Top with cheese
Scatter the remaining ½ cup of shredded cheddar cheese over the surface. This final layer melts into a golden crust that seals in the creamy sauce and adds a buttery, savory finish.

Bake until hot and bubbly
Place the casserole on the middle rack of your preheated 375°F (190°C) oven. Bake uncovered for 25–30 minutes. You’ll know it’s ready when you see steam rising from the edges, the sauce bubbles around the perimeter, and the cheese turns a light golden brown.

Rest before serving
Remove the dish from the oven and let it sit on the counter for 5–10 minutes. This brief resting period allows the sauce to thicken slightly, making it easier to cut neat squares that hold their shape on the plate.

Serve and garnish
Cut the casserole into servings and transfer to plates. For a pop of color and freshness, sprinkle chopped parsley, chives, or a few extra frozen peas on top. Pair with a crisp green salad, steamed broccoli, or warm dinner rolls to complete the meal.

TIPS & VARIATIONS

Swap the soup
Try cream of chicken or cream of celery for a milder, more herbaceous base. Each variety lends a slightly different flavor profile—cream of chicken adds subtle sweetness, while celery brings a gentle, savory note.

Protein alternatives
Substitute ground turkey or chicken for a leaner dish. Because these meats release less fat, add a tablespoon of olive oil when cooking the onion to keep the mixture moist.

Extra vegetables
Stir in 1 cup of diced bell peppers, sliced mushrooms, or steamed broccoli florets along with the rice. These vegetables increase fiber, color, and nutrients without changing the basic method.

Spice it up
For a Tex-Mex twist, add 1 teaspoon of chili powder and ½ teaspoon of cumin when you season the garlic. Top with sliced jalapeños or a dollop of salsa before serving.

Herb garnish
A sprinkle of fresh thyme, rosemary, or flat-leaf parsley just before serving brightens the rich casserole and adds a restaurant-quality finish.

Make-ahead assembly
Prepare the entire casserole up to the point of baking, cover tightly, and refrigerate for up to 24 hours. When you’re ready, uncover and bake as directed—add an extra 5 minutes if the casserole is cold in the center.

Freezer-friendly meal
Bake the casserole, let it cool completely, then wrap the entire dish in foil or transfer portions to freezer-safe containers. Freeze for up to three months. To reheat, thaw overnight and bake at 350°F (175°C) for 20–25 minutes, until warmed through.

Cheese variations
Swap half the cheddar for Monterey Jack, pepper jack, or a melty Mexican-blend cheese to change the flavor and melt characteristics.

Cheesy Ground Beef and Rice Casserole: FAQs & Conclusion

Q1: Can I prepare the casserole ahead of time and refrigerate it before baking?
Yes. Assemble the casserole up to the point of baking, cover tightly with foil or plastic wrap, and refrigerate for up to 24 hours. When you’re ready, uncover and bake as directed, adding an extra 5–10 minutes if the casserole is still cold in the center.

Q2: How can I prevent the rice from drying out during baking?
Ensure that you use two cups of fully cooked rice and maintain the balance of soup, sour cream, and milk in the filling. If you find the mixture too thick before baking, stir in an additional 2–4 tablespoons of milk to keep it creamy.

Q3: My casserole is too soupy—what went wrong?
This usually means either too much liquid or undercooked rice. Drain any excess liquid from canned soup and frozen vegetables before mixing. If the casserole still seems loose, bake it covered for the first 10–15 minutes to trap steam, then uncover to brown the cheese.

Q4: Can I make this dish gluten-free?
Yes—simply substitute a gluten-free condensed cream soup (many brands offer gluten-free mushroom or cheddar soup) and confirm that any seasonings or added ingredients are gluten-free. The rest of the method remains unchanged.

Q5: How should I store and reheat leftovers?
Allow the casserole to cool to room temperature, then cover and refrigerate. It will keep for up to four days. To reheat, microwave individual servings with a splash of milk, or warm the entire dish in a 350°F oven for 15–20 minutes, covered, until heated through.

Q6: Can I freeze the assembled (unbaked) casserole?
Yes. After assembly, wrap the baking dish tightly in foil and freeze for up to three months. To bake, thaw overnight in the refrigerator, then bake at 375°F for 30–35 minutes covered, removing the cover for the final 10 minutes to brown the cheese.

Q7: What’s the best way to add vegetables without making the casserole watery?
Use frozen peas or corn that have been thawed and patted dry, or sauté fresh vegetables (bell peppers, mushrooms, zucchini) in a little oil until just tender, then drain before stirring into the filling. This ensures the final dish remains rich and creamy.
