Ingredients

450 g ground beef

1 cup (100 g) mushrooms, chopped

1 small onion, diced

1 cup (180 g) uncooked white rice

295 g canned cream of mushroom soup

480 ml beef broth

120 g sour cream

1 teaspoon garlic powder

Salt, to taste

Black pepper, to taste

100 g shredded cheddar cheese (optional)

Instructions

1. Prepare Oven and Dish

Preheat oven to 175°C (350°F). Lightly grease a 22 × 33 cm baking dish.

2. Sauté Ingredients

In a skillet over medium heat, cook ground beef, mushrooms, and diced onion until beef is fully browned and vegetables are softened. Drain excess fat.

3. Combine Ingredients

In a large mixing bowl, combine the cooked beef mixture with uncooked rice, cream of mushroom soup, beef broth, sour cream, garlic powder, salt, and black pepper. Stir until evenly mixed.

4. Transfer to Baking Dish

Pour the mixture into the prepared baking dish and smooth the top evenly with a spatula.

5. Bake Covered

Cover tightly with foil and bake for 50–60 minutes, or until rice is tender and liquid is fully absorbed.

6. Add Cheese and Finish Baking

Remove foil, sprinkle shredded cheddar evenly over the top (if using), and bake uncovered for an additional 5 minutes until melted.

7. Rest and Serve

Let the casserole rest for 5–10 minutes before serving to allow it to set.

Notes

For extra flavor, add ½ teaspoon dried thyme or paprika.

Brown rice may be substituted, but increase baking time by 15–20 minutes and add extra broth if needed.

Swap ground beef for ground turkey for a lighter option.

This dish can be assembled ahead and refrigerated up to 24 hours before baking.

Store leftovers in an airtight container for up to 3 days.
