Ingredients

  • 1 lb (450g) ground beef
  • 1 cup long grain white rice (uncooked)
  • 1 tablespoon olive oil
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • 8 oz (225g) mushrooms, sliced (button or cremini)
  • 1 can (10.5 oz) cream of mushroom soup
  • 1 cup beef broth
  • 1 cup milk
  • 1 cup shredded cheddar cheese (optional, for topping)
  • 1 teaspoon Worcestershire sauce
  • ½ teaspoon dried thyme
  • Salt and pepper, to taste
  • Fresh parsley, chopped (for garnish)

Instructions

  1. Preheat oven to 350°F (175°C).
  2. In a large skillet over medium heat, heat olive oil, then add diced onion and garlic. Sauté until softened.
  3. Add ground beef and cook until browned, breaking it up with a spoon. Season with salt, pepper, and thyme.
  4. Stir in sliced mushrooms and cook for 3-5 minutes until they release moisture and begin to brown.
  5. In a large mixing bowl, combine cream of mushroom soup, beef broth, milk, Worcestershire sauce, and uncooked rice. Mix well.
  6. Stir the cooked beef and mushroom mixture into the bowl.
  7. Pour everything into a greased 9×13 inch baking dish and spread evenly.
  8. Cover with foil and bake for 45 minutes.
  9. Remove foil, sprinkle with cheddar cheese (if using), and bake uncovered for another 10-15 minutes, or until the rice is tender and liquid is absorbed.
  10. Let it rest for 5 minutes, garnish with parsley, and serve warm.

Notes

  • You can substitute ground turkey or chicken for a lighter version.
  • Use brown rice for added fiber, but increase cooking time and liquid accordingly.
  • Add frozen peas or green beans for extra veggies.
  • Store leftovers in an airtight container in the fridge for up to 4 days.
  • This dish freezes well—assemble ahead, cover tightly, and freeze for up to 3 months before baking.
