• 1 1/2 teaspoons dried oregano
• 1/2 teaspoon red pepper flakes

1. Preheat the oven to 375°F (190°C).
2. Heat the olive oil in a large pan over medium heat. Add the carrot and onion, and cook until the vegetables have softened slightly, 8-10 minutes.

9. Stir the egg into the cooled meat sauce.
10. Place the largest cabbage leaf on the bottom of a 9-inch (23-cm) round baking dish. Line the exposed sides and bottom of the pan with more cabbage leaves.
11. Spoon in 1/4 of the meat sauce, spreading evenly. Dollop 1/4 of the ricotta on top of the sauce. Cover with cabbage leaves. Repeat with the remaining sauce, ricotta, and cabbage to make 3 more layers.
12. Fold any overhanging cabbage leaves toward the center of the pan.
13. Bake on the middle rack of the oven for 1 hour, until lightly browned on top. Let cool for 20 minutes.
