Ingredients

1 lb ground beef
1 cup uncooked white rice
1 ½ cups beef broth
1 can (10.5 oz) cream of mushroom soup
1 cup mushrooms, sliced
½ cup onion, diced
2 cloves garlic, minced
1 cup shredded cheddar cheese
½ cup milk
1 tablespoon butter
1 teaspoon salt
½ teaspoon black pepper
½ teaspoon paprika
½ teaspoon dried thyme
Fresh parsley for garnish (optional)

Preparation

Preheat your oven to 375°F (190°C) and lightly grease a medium baking dish.
In a large skillet over medium heat, melt the butter. Add the diced onion and cook for about 3 minutes until softened.
Stir in the minced garlic and sliced mushrooms. Cook for another 3–4 minutes until the mushrooms begin to soften.
Add the ground beef to the skillet and cook until browned, breaking it apart with a spoon. Drain any excess grease.
Season the mixture with salt, black pepper, paprika, and thyme. Stir well to combine the flavors.
In a large bowl, mix together the uncooked rice, beef broth, cream of mushroom soup, and milk until smooth.
Add the cooked beef and mushroom mixture to the bowl and stir everything together.
Pour the mixture into the prepared baking dish and spread it evenly.
Cover the dish with foil and bake for 35 minutes.
Remove the foil, sprinkle shredded cheddar cheese on top, and bake uncovered for another 10–15 minutes until the cheese is melted and bubbly.
Let the casserole rest for 5 minutes, then garnish with fresh parsley before serving.

Tips for the Best Beef and Rice Casserole

Use freshly cooked mushrooms instead of canned for the best flavor and texture.

Rinse the rice before adding it to remove excess starch and keep the casserole from becoming too sticky.

For extra flavor, you can add Worcestershire sauce, garlic powder, or a pinch of chili flakes.

If you prefer a richer dish, substitute half of the milk with heavy cream.

Variations You Can Try

Cheesy Upgrade: Add mozzarella or Monterey Jack cheese for extra meltiness.

Vegetable Boost: Mix in peas, carrots, or spinach for added nutrition.

Spicy Version: Add diced jalapeños or red pepper flakes.

Healthier Option: Swap white rice with brown rice (increase baking time slightly).
