Put large pot over medium heat and add olive oil. When olive oil starts sizzling, add cumin seeds, oregano and garlic, stir well and be careful not to burn them. Once spices become fragrant, add ground beef, break down large pieces and saute until no longer pink.
Add carrots, tomatoes and mix the ingredients well. Then stir in nutmeg and paprika. After the spices are combined, add marinara sauce. Let the sauce simmer for 5-6 minutes under low heat then add basil leaves and bay leaves.
As the sauce is simmering, add 3-4 tablespoons of grated pecorino romano cheese to the sauce. Simmer sauce for 1 hour, add water if needed.
When your meat sauce is about ready, boil zucchini noodles for 2 minutes in a separate pot then drain. Pat noodles dry with paper towels. Serve meat sauce and noodles in a bowl and garnish with basil leaves.
