Slow cooker Mexican shredded beef turns out tender, juicy, and packed with complex, savory flavor. It's perfect for making tacos, nachos, quesadillas, and more!
In the bowl of a 3-quart slow cooker, add beef roast. Season all over with chili powder, cumin, oregano, salt, and pepper. Add chiles, onion, and garlic to the slow cooker.
In a bowl, add tomato paste, beef broth, and lime juice. Whisk to combine. Pour over beef roast and cover securely with lid.
Cook on low heat for 8 to 9 hours or on high for 5+ hours.
Remove lid and shred beef with a fork. Serve with tortillas, pico de gallo, and guacamole (or your favorite toppings).
Notes
Chuck roast can be substituted with beef shoulder, brisket, or any tough, marbled cut of beef.
Slow cooking time can vary based on the model and age of your slow cooker as well as the cut and shape of your beef. To ensure roast cooks efficiently, make sure lid is flush with the slow cooker and do not lift the lid during the cooking process.
Leftover beef will keep for 3-4 days in a tightly sealed container in the refrigerator. Store beef with a bit of the liquid from the slow cooker to ensure leftovers reheat nice and juicy.
Use shredded beef for tacos, burritos, bowls, nachos, quesadillas, taquitos, or enchiladas.
