A serving bowl filled with Mexican shredded beef.

I love a good slow cooker meal. This Mexican shredded beef turns out perfectly tender, juicy, and full of savory flavor with about 5 minutes of prep. Once assembled, the slow cooker does all the work for you!

By dinnertime you'll have flavorful shredded beef that can be assembled into tacos, burritos, or whatever variation your heart desires. Serve it with some tortillas, pico de gallo, and guacamole and you're all set.

Do you enjoy meal prepping? Shredded beef leftovers reheat beautifully, so it's perfect for assembling lunches for the entire week.

Ingredients and substitutions

Ingredients on a counter top.
  • Beef - One 3-4 pound chuck roast works well for this recipe. Any tough cut of beef with marbling works well in this recipe. Shoulder roast, round roast, or brisket are great alternatives.
  • Aromatics - Onion and garlic add flavor to the recipe. Four cloves of garlic could be substituted with 1 teaspoon of garlic powder if needed.
  • Seasoning - This recipe calls for a significant amount of seasoning. Don't worry, as long as you're using the proper size of meat, it won't turn out over-seasoned or salty! Chili powder, cumin, oregano, salt, and pepper add depth of flavor to the meat.
  • Chiles - One can of hot or mild green chiles adds flavor and a little heat to the roast.
  • Tomato paste - Adds depth and savory flavor to the roast.
  • Lime juice - Adds a bit of acidity and brightness to cut through the richness of the beef roast. Liquid also helps keep the roast juicy while cooking.
  • Beef broth - Adds savory flavor and a bit of liquid to the slow cooker to prevent burning or drying out on the bottom.

Tips and tricks

Making Mexican shredded beef in a slow cooker.

Use a properly sized slow cooker - For a 3-4 pound chuck roast, I use a 3 quart slow cooker. Make sure your slow cooker is filled about ½ to ¾ full. The lid must fit securely on top without any gaps (this slows down cooking time). You also don't want to use a slow cooker that's too large - all the extra surface area causes faster evaporation and can dry out the beef.

Don't lift the lid - This recipe doesn't require any stirring or flipping, so don't be tempted to remove the lid from your slow cooker. This slows down cooking time substantially, especially if you're lifting the lid repeatedly throughout the day.

For best flavor, don't omit ingredients - This may seem obvious, but if you'd like a juicy, tender, and flavorful roast, don't omit any of the listed ingredients. Check out the 'ingredients and substitutions' section above to understand what each ingredient adds to the recipe.

Frequently asked questions

What cut of beef is best for shredded beef?

I like chuck roast because it's easy to find at my local grocer. Any cut of beef that's tough and has marbling works great for a slow cooker recipe. Beef shoulder and brisket are also great options.

How do you keep shredded beef from drying out?

- Don't lift the lid of your slow cooker - this releases moisture and heat, which increases cooking time and can dry out the meat if it's done repeatedly.
- Store leftover meat with some of the liquids from the slow cooker. Reheat the meat in some of the liquids to ensure it turns out juicy and tender.

What do you serve with shredded beef?

For an easy meal, serve Mexican shredded beef with tortillas and a few of your favorite toppings, like guacamole, pico de gallo, and sour cream. For a fun family dinner idea, make a toppings bar with shredded cheese, salsa, fresh cilantro, pickled jalapenos, steamed rice, Mexican rice, shredded lettuce, refried beans, and black beans.

How long do leftovers last?

USDA recommends using leftover cooked beef within 3-4 days when stored in a tightly sealed container in the refrigerator.

I cooked my roast according to the recipe but it wasn't done. What happened?

If your roast isn't done in the recommended times below, here are a few things to consider:
- Does the lid fit securely on the slow cooker without gaps?
- Did you lift the lid throughout the day to check on your roast?
- Are you using an older slow cooker?
All of these reasons can cause your roast to cook slower and require extra cooking time. Newer slow cookers tend to cook a little faster than older varieties. While there's nothing wrong with an older slow cooker, you may want to keep this in mind when using one.

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.
