Beef Ragu

Heat oil in a large Dutch oven over medium-high. Season chuck roast with pepper and 2 teaspoons salt. Sear meat until browned on every side, working in batches if necessary, about 10 minutes. Remove from Dutch oven and transfer to a large plate.

Reduce heat to medium and stir in onion. Cook, stirring often, until softened, about 8 minutes. Add garlic and cook, stirring constantly, until fragrant, about 1 minute. Stir in harissa and tomato paste; cook, stirring constantly, until caramelized, about 2 minutes.

Pour in wine and cook, scraping the bottom of the pot with a wooden spoon to loosen any browned bits, until reduced by two thirds, about 5 minutes. Stir in tomatoes, bay leaf, chuck roast, and remaining 1 teaspoon salt. Reduce heat to medium-low and cover. Cook, stirring occasionally, until meat is tender, sauce has thickened, and flavors meld, about 2 1/2 hours.

Remove and discard bay leaf. Transfer meat from Dutch oven to a cutting board and shred using 2 forks. Return meat to pot and stir in pappardelle. Top with grated Parmesan cheese.
