How to Make It
In a Dutch oven, over medium heat, heat the oil. Add the onion and saute for 3 minutes. Add the celery, carrot, and garlic and cook for 5 minutes more. Add the pancetta and cook for 5 minutes, then add the beef and cook until brown. Add the wine and the remaining ingredients and simmer for 45 minutes. Serve with cooked fettuccine. Sprinkle with Parmesan.
To Freeze: Omit the pasta and the Parmesan. Let the sauce cool, then ladle it into resealable freezer bags. Store for up to 3 months.
To Reheat: Thaw the sauce overnight in the refrigerator or thaw partially in the microwave. Warm in a covered saucepan over medium-low heat for 20 minutes. Meanwhile, cook the pasta. Spoon the sauce over it and sprinkle with Parmesan.
