Cut boneless beef brisket into quarters.
3 pounds boneless beef brisket
Season brisket with salt and pepper. Add olive oil to a large heavy-bottom pan over medium-high heat. Once hot, add brisket and cook for a couple of minutes on each side until browned all over. Place the beef in the slow cooker.
3 pounds boneless beef brisket, 2 tablespoon extra-virgin olive oil, ½ teaspoon salt, 1 teaspoon freshly ground black pepper
Without cleaning the saucepan, add garlic, onions, celery, and carrots. Saute and stir until soft, around 5 minutes.
1 clove garlic, 1 ½ cups onion, 3 stalks celery, 2 medium carrots
Add wine and continue to saute until the liquid has almost evaporated (about 1 minute). Add tomato paste, tomato puree, and beef stock. Stir and bring to a simmer.
½ cup red wine, ⅓ cup tomato paste, 1 ½ cups tomato puree, ¾ cup beef stock
Mix in oregano, sugar, pepper, salt, and bay leaves. Slowly add milk while stirring to combine.
1 tablespoon, 2 teaspoons sugar, 2 dried bay leaves, ½ cup whole milk
Pour the mixture from the pan over the beef in the slow cooker. Cook on low for 6-8 hours, stirring every so often. It's ready when the beef shreds easily with a fork.
Remove the meat to a cutting board and use 2 forks to pull it apart. Return it to the slow cooker and mix it well with the sauce.
Boil a large pot of water. Season with salt, then add pasta and cook, stirring occasionally, until al dente. Drain, reserving ½ cup of the pasta water.
Add the pasta to the ragu in the slow cooker and toss to coat. Stir in reserved patsa water by the Tablespoon if the sauce needs more liquid. Serve with grated parmesan and parsley, and enjoy!
