How to Make Cheesy Ground Beef and Rice Casserole Recipe

Step 1: Brown the Ground Beef

Start by heating a large pot over medium-high heat and cooking the ground beef until it’s browned and fragrant. Season it with salt, pepper, and Italian seasoning. The browned beef builds a savory foundation that makes this casserole utterly satisfying. Once cooked, drain off any excess grease and set it aside covered with foil to keep warm.

Step 2: Sauté Onions and Garlic

Using the same pot, melt 2 tablespoons of butter and add the diced onions. Cook them gently for about 5 minutes until softened and translucent. Toss in the minced garlic and cook for another minute to release its aromatic flavor. This step softens the veggies and deepens the overall flavor profile.

Step 3: Cook the Rice with Broth

Add the beef broth, remaining butter, and uncooked rice to the pot. Stir everything together, then bring it to a boil. Once boiling, reduce the heat to a low simmer and cover the pot tightly. Let the rice cook for about 10 minutes before adding the mushrooms.

Step 4: Add Mushrooms and Finish Cooking Rice

After the initial 10 minutes of cooking, stir in the sliced mushrooms, cover the pot again, and continue simmering for another 5 to 10 minutes, or until the rice is tender. Important: Avoid stirring the rice to allow it to cook evenly. Once done, turn off the heat and let it stand covered for 10 minutes. This resting time will ensure any stuck rice loosens up nicely.

Step 5: Combine Casserole Ingredients

Return the cooked ground beef to the pot along with the cream of mushroom soup, milk, sour cream, and half of the cheddar cheese. Stir gently to combine all ingredients until creamy and well mixed. The mixture should look rich and hearty—promise it’s about to get even better in the oven!

Step 6: Bake to Perfection

Transfer the mixture to a lightly greased 9 x 13 casserole dish. Sprinkle the remaining cheddar cheese evenly over the top. Cover the dish and bake in a preheated 350-degree oven for 20 minutes. The cheese will melt into a bubbly, golden crust that makes this Cheesy Ground Beef and Rice Casserole Recipe absolutely irresistible.

Garnishes

A sprinkle of freshly chopped parsley or green onions adds a pop of color and a touch of brightness that beautifully balances the richness of the casserole. For an extra kick, a dash of crushed red pepper flakes can also liven up each cheesy bite.

Side Dishes

Pair this hearty casserole with a crisp green salad dressed in a light vinaigrette or steamed green beans to add freshness and crunch. Roasted vegetables or a tangy coleslaw can also provide a pleasing contrast in flavor and texture.

Creative Ways to Present

For a charming presentation, serve the casserole in individual ramekins or mini cast iron skillets right out of the oven. This personal touch adds a cozy vibe and makes everyone feel special. Alternatively, garnish each serving with a dollop of sour cream or a spoonful of salsa for an added flavor dimension.

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer leftover casserole to airtight containers and store in the refrigerator for up to 3 days. The flavors will deepen overnight, making it a perfect next-day meal.

Freezing

This Cheesy Ground Beef and Rice Casserole Recipe freezes beautifully. Just cool completely, portion into freezer-safe containers, and freeze for up to 3 months. When ready to eat, thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers in the microwave or oven until warmed through. If using the oven, cover the casserole with foil to keep it moist and heat at 350 degrees for 20-25 minutes. A sprinkle of extra cheese on top before reheating can bring a fresh cheesy touch back to life.

FAQs

Can I use brown rice instead of white rice?

Absolutely! Brown rice will add a nuttier flavor and chewier texture, but keep in mind it requires more liquid and a longer cooking time. Adjust the broth accordingly and be patient as it simmers.

Is there a vegetarian version of this casserole?

Yes! Simply replace the ground beef with sautéed mushrooms, lentils, or plant-based meat alternatives. Use vegetable broth instead of beef broth and skip any meat-based ingredients to keep it vegetarian-friendly.

Can I make this casserole gluten-free?

Ensure your cream of mushroom soup is gluten-free, or make a homemade version using gluten-free flour. The other ingredients are naturally gluten-free, making it easy to adapt for gluten sensitivities.

How can I add more vegetables to this dish?

Feel free to toss in diced bell peppers, shredded carrots, or peas when you add the mushrooms. These veggies complement the flavors and add vibrant color and extra nutrition.

What’s the best type of cheese to use?

Cheddar cheese is classic for this recipe because it melts well and adds sharpness, but you can mix in mozzarella, Monterey Jack, or a blend for different cheesy textures and flavors.
