Why You’ll Love Cheesy Ground Beef and Rice Casserole Recipe

I love this recipe because it’s incredibly easy, budget-friendly, and packed with comforting flavors. I like that I can prepare everything in one pot before baking, which keeps cleanup simple. The combination of tender rice, seasoned beef, mushrooms, and melted cheese makes this casserole feel extra cozy and satisfying.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

▢1 lb. ground beef, 85% lean
▢1.5 teaspoons Italian seasoning
▢Salt/Pepper
▢3 Tablespoons butter, divided
▢¾ cup onions, diced
▢1 Tablespoon garlic, minced
▢2 ½ cups beef broth
▢1 ¼ cups uncooked white long grain rice, (not instant rice)
▢8 oz. sliced button mushrooms, washed
▢10.5 oz. cream of mushroom soup
▢½ cup milk, any kind
▢½ cup sour cream
▢2 cups cheddar cheese, divided

Directions

I begin by preheating my oven to 350 degrees. In a large pot over medium-high heat, I brown the ground beef and season it with salt, pepper, and Italian seasoning as it cooks. Once browned, I drain the grease, transfer the beef to a plate, and cover it with foil.

In the same pot, I melt 2 tablespoons of butter and add the diced onions, cooking them for about 5 minutes until softened. I add the garlic and cook for one more minute. Next, I add the beef broth, remaining butter, and uncooked rice, stirring everything together.

I bring the mixture to a boil, then reduce it to a simmer. I cover the pot tightly and cook for 10 minutes. Without stirring, I add the mushrooms, replace the cover, and continue cooking for another 5 to 10 minutes, following the rice package cooking time.

Once done, I turn off the heat and let the pot stand, covered, for 10 minutes without stirring. I then add the cooked ground beef back into the pot along with the cream of mushroom soup, milk, sour cream, and half of the cheese. I stir everything together until well combined.

I transfer the mixture to a lightly greased 9 x 13 casserole dish, top it with the remaining cheese, cover, and bake for 20 minutes. I serve it hot and enjoy every creamy bite.

Servings and Timing

I make this casserole to serve 6 people. Prep time is about 10 minutes, cook time is roughly 50 minutes, and total time comes to around 1 hour.

Variations

I sometimes swap the ground beef for ground turkey when I want a lighter option. I also like adding peas or diced carrots for extra vegetables. When I want more flavor, I mix in a little shredded mozzarella or Monterey Jack along with the cheddar.

Storage/Reheating

I store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, I warm portions in the microwave or cover and heat in the oven at 350 degrees until heated through. I add a splash of milk if it needs extra moisture.
