Tip!

You’ll find all ingredient quantities in the recipe card below.

Ground beef: I like using 85% lean beef for the perfect fat balance that keeps the dish juicy without too much grease.
Italian seasoning: This blend adds a subtle herbaceous note that lifts the beef’s flavor beautifully.
Onions and garlic: These aromatics are essential for building that savory base flavor that makes the casserole irresistible.
Beef broth: It’s key for cooking the rice and infusing it with deep, meaty flavor.
White long grain rice: It cooks fluffy and absorbs all the delicious liquids without turning mushy.
Button mushrooms: They add an earthy, chewy texture that pairs wonderfully with the creamy sauce.
Cream of mushroom soup: This brings creaminess and richness, tying all ingredients together perfectly.
Milk and sour cream: These add silkiness and tang, rounding out the flavor and texture.
Cheddar cheese: Divided into two portions, half goes inside for melty goodness, and the other half on top for a golden, bubbly crust.
Butter: Used to sauté the onions and add a nice richness throughout the dish.

Directions

Step 1: Preheat your oven to 350 degrees Fahrenheit. This will ensure the casserole bakes evenly once everything is combined.

Step 2: In a large pot over medium-high heat, brown the ground beef. As it cooks, season with salt, pepper, and Italian seasoning. Stir occasionally until completely browned and flavorful.

Step 3: Drain off any grease to keep the casserole from becoming oily. Transfer the beef to a plate and cover with foil to keep warm while you prepare the rest.

Step 4: Melt 2 tablespoons of butter in the same pot to soak up all the beefy flavors left behind. Add the diced onions and cook them for about 5 minutes, or until softened and translucent. Then, stir in the minced garlic and cook for an additional minute until fragrant.

Step 5: Pour in the beef broth, add the remaining tablespoon of butter and the uncooked rice. Stir everything together to combine well. Bring the pot to a boil, then reduce the heat to a simmer.

Step 6: Cover the pot tightly and let it cook for 10 minutes. Resist the urge to lift the lid or stir, as this helps the rice cook evenly and absorb the broth fully.

Step 7: After 10 minutes, add the sliced mushrooms on top without stirring. Recover and continue cooking for another 5 to 10 minutes, following your rice package’s cooking time instructions.

Step 8: Turn off the heat and leave the lid on, allowing the rice to stand, undisturbed, for 10 minutes. This resting lets any remaining liquid absorb and the rice finish cooking to perfection.

Step 9: Remove the lid, then add the cooked ground beef back into the pot along with the cream of mushroom soup, milk, sour cream, and half of the shredded cheddar cheese. Stir gently but thoroughly to combine every ingredient into a creamy, cohesive mixture.

Step 10: Lightly grease a 9x13 casserole dish and transfer the entire mixture into it. Sprinkle the remaining cheese evenly over the top for that irresistible golden crust.

Step 11: Cover the dish with foil and bake in the preheated oven for 20 minutes. When done, remove the foil and let it sit for a few minutes before serving so the casserole sets nicely.

Servings and Timing

This Cheesy Ground Beef and Rice Casserole Recipe serves about 6 hearty portions, making it ideal for families or leftover-friendly meal prep. The prep time usually takes around 15 minutes, mostly for browning the beef and chopping ingredients. Cooking the rice and mushrooms on the stovetop takes about 25 minutes in total, while the oven baking adds another 20 minutes. Altogether, you’re looking at roughly 1 hour from start to finish, with a small resting period after baking to let everything meld together beautifully.

How to Serve This Cheesy Ground Beef and Rice Casserole Recipe

The left side reveals layers of ingredients before mixing: on the top left is a pile of cooked ground meat in dark brown color, below it to the left is shredded pale yellow cheese, in the bottom center is cooked rice with mushrooms mixed in, appearing light tan with darker mushroom pieces, and on the right side there is a white creamy sauce in two separate portions. On the right side of the image, all the ingredients are fully mixed together, forming a thick, creamy mixture with a pale tan color and small darker bits throughout, showing a smooth but textured surface.

I love serving this casserole hot and fresh from the oven, where the cheese is perfectly melted and bubbly on top. On a weeknight, it pairs beautifully with a simple green salad dressed in vinaigrette or some roasted veggies like broccoli or green beans to add a fresh crunch and a pop of color to the plate. For a heartier meal, I might add garlicky sautéed spinach or a crisp coleslaw to balance the richness.

When it comes to garnishing, a sprinkle of freshly chopped parsley or chives adds a lovely visual touch and a hint of brightness to cut through the creamy flavors. If you want to make it extra special for guests, a side of warm crusty bread or garlic knots is always a welcome addition. For beverages, I find a medium-bodied red wine like a Merlot or Zinfandel complements the beef and cheese perfectly, while for non-alcoholic options, a sparkling water with a wedge of lemon or a lightly brewed iced tea refreshes the palate nicely.

This casserole is wonderfully versatile for many occasions—from cozy family dinners to casual potlucks or even game day snacking. I recommend serving portions around one to one and a half cups per person, plated warmly so everyone enjoys every gooey, cheesy bite.

Variations

I’ve had lots of fun adapting this Cheesy Ground Beef and Rice Casserole Recipe in different ways depending on dietary needs and flavor cravings. If you want a veggie-packed version, try swapping some or all of the ground beef for black beans or cooked lentils—they add protein and fiber without sacrificing the hearty feel. For a gluten-free twist, just double-check that your cream of mushroom soup and broth are GF compliant or make your own dairy-based white sauce from scratch.

Another variation I adore is adding a spicy kick by mixing in some diced jalapeños or a dash of cayenne pepper to the beef while browning. Alternatively, you could swap out cheddar for a smoky gouda or pepper jack to change up the cheese flavor profile. For an even richer casserole, stir in some cooked bacon bits or caramelized onions before baking.

If you’re short on time or want a different texture, you can also prepare the rice separately according to package instructions, then combine all ingredients before baking. Or for an even simpler one-pot method, skip baking entirely and just let everything simmer together on the stove with a lid until creamy and cooked through, finishing with a quick broil of cheese on top under the oven’s grill settings.

Storage and Reheating

Storing Leftovers

After enjoying your cheesy casserole, you’ll want to store leftovers properly to maintain their flavor and texture. I recommend transferring any uneaten portions into airtight containers within two hours of cooking. Glass or BPA-free plastic containers with tight-fitting lids work best. Stored in the refrigerator, leftovers will stay fresh for up to 3-4 days, making them perfect for next-day lunches or easy dinners.

Freezing

This casserole freezes really well, which is one of the reasons I love it so much. To freeze, place cooled portions into freezer-safe containers or heavy-duty freezer bags, removing as much air as possible to prevent freezer burn. You can store it for up to 3 months. When ready to enjoy, thaw the casserole overnight in the fridge before reheating for best texture and flavor.

Reheating

To reheat, I find the oven method works best to revive the cheesy crust and keep everything warm and creamy. Preheat your oven to 350 degrees Fahrenheit, cover the dish with foil, and heat for about 20-25 minutes if thawed, or a bit longer if reheating from frozen. You can also reheat individual portions in the microwave—adding a splash of milk or broth helps prevent drying out—but watch carefully to avoid overcooking, which can make the rice tough and the beef rubbery.

FAQs

Can I use brown rice instead of white rice in this casserole?

Yes, you can substitute brown rice, but keep in mind it needs a longer cooking time and more liquid compared to white rice. I suggest cooking the brown rice separately before combining it with the other ingredients to ensure it’s fully tender without drying out the casserole.

Is there a way to make this casserole dairy-free?

Absolutely! You can swap the sour cream for a dairy-free or plant-based alternative such as coconut or almond milk yogurt. Use a dairy-free cheese substitute for the cheddar and choose a dairy-free cream of mushroom soup or make your own using mushrooms, vegetable broth, and non-dairy milk. This way, you still get creamy texture without dairy.

Can I prepare this recipe in advance?

Definitely. You can brown the beef and prepare the rice and mushroom mixture ahead of time, then combine everything and store it in the fridge before baking. Just bring the casserole back to room temperature for about 20 minutes before popping it in the oven to ensure even heating.

What can I serve with this casserole for a complete meal?

I recommend pairing it with a fresh green salad or steamed vegetables to add some brightness and crunch. Roasted carrots, green beans, or Brussels sprouts work beautifully. A light vinaigrette or lemon dressing can balance the richness of the casserole nicely.

Can I add other vegetables to this casserole?

Yes, feel free to mix in veggies like bell peppers, peas, or spinach either when you sauté the onions or stir them in before baking. Just adjust the cooking time to ensure they’re tender. Adding extra vegetables is a great way to boost nutrition and add color.

Conclusion

I truly hope you give this Cheesy Ground Beef and Rice Casserole Recipe a try because it’s one of those dishes I keep coming back to for its comforting, crowd-pleasing flavors and simple prep.
