Preheat your oven to 350°F (175°C).
Bring a large pot of water to a boil and blanch the cabbage for 2-3 minutes.
Carefully remove the outer leaves and set them aside to cool.
In a skillet, sauté the onion and garlic until translucent.
In a bowl, mix ground beef, cooked rice, sautéed onion, garlic, paprika, salt, and pepper.
Place 2-3 tablespoons of filling in the center of each cabbage leaf.
Fold in the sides and roll up tightly.
Spread a layer of tomato sauce on the bottom of a baking dish.
Arrange the cabbage rolls seam-side down in the dish.
Top with remaining tomato sauce and cover with foil.
Bake for 45 minutes, then uncover and bake for an additional 15 minutes.
