Season beef with salt and pepper.
In a dutch oven, heat 1 tbsp of olive oil over high heat. Brown beef on all sides until very brown (5 minutes). Remove beef and set aside.
Reduce heat to medium low and add remaining olive oil. Sauté garlic and onion for 2-3 minutes. Then add carrots and celery and sauté for 5-6 minutes.
Add tomatoes, paste, broth, wine, and spices. Return beef and any juices to pot. Increase heat and bring to a simmer. Turn heat back down to low--it should be bubbling gently.
Cover and cook for 2 hours or until beef is tender. Remove beef and shred with 2 forks. Remove bay leaves. Return beef to pot and simmer for 30 minutes until sauce is thickened. Season with salt and pepper. Cover sauce and set aside until ready to serve.
Bring a large pot of water to boil. Add salt. Add pappardelle and cook for 1 minute less than package directions.
While pasta is cooking, place 5-6 cups of the ragu in a large skillet. Heat over high heat while pasta cooks.
When pasta is ready, transfer directly to skillet using tongs. Add 3/4 cup water to skillet. Gently toss the pasta 1-2 minutes until sauce is thickened and coats pasta.
Serve with grated Parmigiano reggiano and parsley.
