Ingredients You’ll Need

1 lb (450 g) ground beef – lean is best to avoid excess grease
1 cup uncooked rice (white or brown; adjust cooking time accordingly)
1 medium onion, finely chopped
2 cups mushrooms, sliced (button, cremini, or a mix)
2 cloves garlic, minced
1 can (10.5 oz) cream of mushroom soup (or homemade equivalent)
1 ½ cups beef broth
1 cup shredded cheddar cheese
1 cup shredded mozzarella cheese
2 tbsp olive oil or butter
1 tsp dried thyme
½ tsp paprika
Salt and black pepper, to taste
Fresh parsley, chopped (for garnish)

Step-by-Step Method

Step 1: Prepare the Rice Base

Start by pre-cooking your rice until it’s just tender but not fully done (it will finish baking in the oven). This helps the grains absorb flavor without turning mushy. Drain and set aside.

Step 2: Sauté the Beef and Aromatics

In a large skillet, heat olive oil or butter over medium heat. Add the chopped onion and cook until translucent, about 3–4 minutes. Stir in the garlic and cook for another 30 seconds, releasing its aroma.
Next, add the ground beef. Break it apart with a spatula and cook until browned all over. Season with salt, black pepper, paprika, and thyme. Once done, drain any excess fat.
