- 1 lb. ground beef (85% lean)
- 1.5 teaspoons Italian seasoning
- Salt and pepper, to taste
Vegetables and Aromatics
- ¾ cup onions, diced
- 1 tablespoon garlic, minced
- 8 oz. sliced button mushrooms, washed
Liquids and Dairy
- 2 ½ cups beef broth
- 3 tablespoons butter (divided: 2 tbsp + 1 tbsp)
- ½ cup milk (any kind)
- ½ cup sour cream
Other
- 1 ¼ cups uncooked white long grain rice (not instant rice)
- 10.5 oz. cream of mushroom soup
- 2 cups cheddar cheese (divided: 1 cup + 1 cup)
Instructions
- Prepare Ingredients: Gather all ingredients and check your rice package for exact liquid amounts and cooking time. This recipe uses 2 ½ cups beef broth and 1 ¼ cups uncooked rice for reference.
- Preheat Oven: Set your oven to 350°F (175°C) to prepare for baking the casserole later.
- Brown the Ground Beef: In a large pot over medium-high heat, cook the ground beef until fully browned. Season with salt, pepper, and Italian seasoning during cooking for flavor enhancement.
- Drain and Set Aside Beef: Drain excess grease from the beef, transfer it to a plate, and cover with foil to keep warm.
- Sauté Onions and Garlic: Using the same pot, melt 2 tablespoons of butter. Add diced onions and cook for about 5 minutes until softened. Add minced garlic and cook for an additional minute until fragrant.
- Add Liquids and Rice: Pour in the beef broth and add 1 tablespoon of butter plus the uncooked rice. Stir to combine all ingredients well.
- Simmer Rice Mixture: Bring the mixture to a boil, then reduce to a simmer. Cover the pot tightly and cook for 10 minutes without stirring.
- Add Mushrooms: Place the sliced mushrooms on top, cover the pot again, and cook for another 5 to 10 minutes, following rice package’s recommended cooking time. Do not stir to avoid disturbing the rice.
- Let Rice Stand: Turn off heat, keep the pot covered, and let it stand undisturbed for 10 minutes to finish cooking and allow any stuck rice to release naturally.
- Combine Beef and Creamy Ingredients: Return the cooked ground beef to the pot. Add cream of mushroom soup, milk, sour cream, and half of the cheddar cheese. Stir gently to mix all the components together.
- Transfer to Casserole Dish: Lightly grease a 9 x 13 inch casserole dish and pour the mixture into it. Evenly sprinkle the remaining cheddar cheese on top.
- Bake: Cover the casserole with foil or a lid and bake in the preheated oven for 20 minutes, until the cheese on top is melted and bubbly.
- Serve: Remove from oven and serve warm for a delicious, hearty meal.
Notes
- For best rice texture, follow your rice package instructions regarding liquid ratios and cooking time.
- You can cook the rice separately if preferred; use 3¾ cups cooked rice in step 10.
- Use medium cheddar cheese for best melt and flavor balance.
- Ensure to not stir the rice during simmering to prevent mushy texture.
- This casserole stores well and tastes great reheated for leftovers.
