Preheat the oven to 350°F (180°C). Lightly grease a 9 x 13-inch baking dish with cooking spray.
Cooking spray
In a large bowl, combine the ground beef, Worcestershire sauce, egg, cooked rice, onion, parsley, garlic, salt, black pepper, dried dill, onion powder, red chili flakes, and ½ cup of the tomato sauce. Mix gently until fully combined.
1 cup cooked long-grain rice, 1½ pounds lean ground beef, ½ tablespoon Worcestershire sauce, 1 large egg, 1 cup yellow onion, ⅓ cup fresh parsley, 3 cloves garlic, ½ teaspoon dried dill, ½ teaspoon onion powder, ½ to 1 teaspoon red chili flakes, Salt and black pepper, 5 cups tomato sauce
Bring a large pot of water to a boil. Carefully place the whole cabbage into the boiling water. Cover partially and cook for 8 to 10 minutes, turning halfway through, until the outer leaves are softened.
1 large head cabbage
Remove the cabbage from the pot and allow it to cool slightly. Gently peel off the softened leaves and trim the thick core from each leaf. If needed, return the cabbage to the boiling water to soften additional leaves.
You will need approximately 18 cabbage leaves for rolling and 8 to 10 extra leaves to line the baking dish.
Line the bottom of the prepared baking dish with the extra cabbage leaves.
Place about ¼ cup of the meat mixture in the center of each cabbage leaf. Fold in the sides and roll tightly. Arrange the rolls seam-side down in the baking dish.
In a bowl, combine the remaining 4 and ½ cups of tomato sauce with the water. Pour the sauce evenly over the cabbage rolls.
½ cup water
Cover the dish tightly with aluminum foil and bake for 2 hours, or until the meat is fully cooked and reaches an internal temperature of 165°F.
Carefully remove the foil and allow the cabbage rolls to rest for 20 minutes before serving.
