The secret to the best shredded beef is to cook it low and slow. We use our oven, but you can use a slow cooker. Check the notes section in the recipe below for my tips on cooking the beef in your slow cooker. I love serving this super tender beef in tortillas for shredded beef tacos, but you can skip the tortillas and serve with rice, in burritos, or over salad.
4 to 5 pounds boneless beef chuck, trimmed of excess fat
2 tablespoons avocado oil
Salt
4 cloves garlic, smashed
1 tablespoon tomato paste
1 tablespoon chili powder, see homemade chili powder
1 tablespoon ground coriander
1 tablespoon ground cumin
2 bay leaves
2 cinnamon sticks
Flour tortillas or corn tortillas, warmed
Taco toppings such as guacamole, sliced avocado, homemade salsa, onion, cilantro, pickled onions, cheese, and lime
Preheat the oven to 300°F (148°C). Set aside a large Dutch oven or oven-safe pot with a lid.
Pat the beef dry, and then generously season both sides with salt.
Heat the oil in the Dutch oven over medium-high heat. Add the seasoned beef and cook, turning occasionally, until well-browned on all sides, about 8 minutes.
Scatter garlic cloves, tomato paste, chili powder, coriander, cumin, bay leaves, and cinnamon sticks around the beef.
Pour enough water so it comes up about three-quarters of the way up the side of the beef. Stir, then cover the pot with its lid. Slide into the oven and cook until the meat is fall-apart tender, 2 ½ to 3 hours.
Transfer the meat to a bowl, let it cool, then shred it with a fork.
Strain the cooking liquid and skim off most of the fat at the surface. Return the strained liquid to the pot and simmer over medium-high heat until reduced by about half. Taste the liquid and adjust with more salt as needed.
Pour some (or all) of the reduced liquid over the shredded beef. Serve with tortillas and taco toppings.
