• 2 cups beef broth may substitute chicken broth or chicken stock• ¼ cup water (60ml)• 28 oz crushed tomatoes (794g)• ¼ teaspoon crushed red pepper optional• 2-3 fresh thyme springs or 1 teaspoon dried thyme• 2 dried bay leavesFor Serving• 12 oz-1 lb Pappardelle or preferred pasta for serving (375-500g)• Parmesan cheese for serving
Season beef on all sides with salt and pepper. Heat oil in a large enameled Dutch oven over medium/high heat. Once oil is shimmering, add beef and sear on all sides until deep brown in color
Set beef aside. Reduce heat to medium. Add butter to the pot and, once melted, add carrot, celery, and onion and cook, stirring occasionally, until softened (about 3-5 minutes).
Deglaze the pan by slowly pouring in red wine vinegar and scraping the bottom of the pan to loosen any brown bits. Cook until the vinegar is reduced by about 50%.
Remove beef from the pot. Use a potato masher to break up the vegetables in the pot (for a smoother sauce, use an immersion blender, but I like mine a bit heartier).
