5-Ingredient Slow Cooker Mexican Shredded Beef

Learn how to make shredded beef in a slow cooker with this easy 5-ingredient recipe for Mexican shredded beef. Thanks to beef shoulder roast, this pulled beef is a bit leaner than typical shredded chuck roast. That leaves you plenty of room to make awesome shredded beef tacos, enchiladas, nachos, burrito bowls, and more.

How to Make Shredded Beef in a Slow Cooker

If you’ve ever made a Mississippi pot roast, this Mexican beef draws inspiration from that. You’ll start by adding a can of crushed tomatoes to a slow cooker and seasoning a beef shoulder roast or chuck roast with beef fajita seasoning. Next, you’ll place the roast in the slow cooker and top with ranch seasoning and pickled jalapeño peppers.

Cook the beef roast for eight to ten hours until it’s fall apart tender. Start checking at the eight-hour mark and if it doesn’t easily shred when poked with a fork, continue cooking.

Additional cooking methods: I’ve included notes for pressure cooking and even smoking on a pellet grill in the recipe card’s notes section below.

You shouldn’t need to reduce or thicken the remaining tomato sauce. Simply toss the shredded beef in the sauce and it will absorb most of the juices.

If you’d like an onion-heavy base instead of tomato sauce, my slow cooker beef shoulder roast is essentially the same recipe with sliced white onion instead of crushed tomatoes at the base.

I like to add a few lime wedges and cilantro in the slow cooker while the beef rests in the juices for about 30 minutes before serving.

Making Shredded Beef Tacos and Quesadillas

Fill warmed corn tortillas with this beef, garnish with cilantro and onion (plus some homemade avocado salsa verde), and get ready to have some of the best slow cooker tacos you’ll come across. For a richer experience, throw some flour tortillas on a griddle with cheese to make awesome quesadillas. Both are great, but the serving possibilities go way beyond tacos.

Other Ways to Serve

You could swap this beef for brisket in my leftover brisket kolaches or substitute for barbacoa in my leftover barbacoa enchiladas and double decker barbacoa tostadas.

And my crispy baked beef and cheese tacos, beef taquitos, and air fried quesadillas would all work great with pulled beef instead of ground beef or pulled chicken.

To keep things lower calorie, make thin corn tortilla chips in the oven and top with this beef to make nachos. Cauliflower rice burrito bowls would also be a great fit for this beef. Not a fan of cauliflower rice? Check out my teriyaki ground beef bowls to see how I make a rice blend to hide it.

Other Slow Cooker Creations

I have recipes for chili mac and shredded beef enchilada casserole that are made entirely in a slow cooker, and this beef would be perfect for making something similar.

For the latter, just fold some chopped corn tortillas and grated jack cheese in with the finished beef, top with a bit more cheese, and cover for 15-20 minutes to melt the top layer of cheese.

And to make the chili mac, just add two boxes of Goodles or a boxed mac and cheese, cover, and cook on high for 30 minutes before stirring in the cheese packets and 3/4 cup of milk. Then toss an extra 3-4 ounces of shredded cheese on top and cover to melt.

No matter how you serve your slow cooker shredded beef, I hope you enjoy it! If you do, I always appreciate recipe reviews. Just click the star rating in the recipe card below to let me know your thoughts.

**I used H-E-B beef fajita seasoning, which includes spices as well as a tenderizer, but any fajita seasoning will work. Bolner's Fiesta brand makes a similar product.

For Mexican Shredded Beef in a Pressure Cooker or on a Smoker

Using my smoked chuck roast tacos as a guide, season the roast with fajita seasoning and smoke at 200ºF for about 2 hours before adding to a Dutch oven or foil wrapped grill pan with the tomatoes and remaining ingredients. Cover and increase the grill temperature to 275ºF. Cook for 4-5 hours until the beef easily shreds.

To make shredded beef in a pressure cooker, you can season and sear the roast using a pressure cooker's sauté function before adding the remaining ingredients and cooking with high pressure for 90 minutes. (Source: Pressure Cooker Pot Roast) You can also cut the roast into smaller pieces for faster cooking. Four smaller pieces should cook in about 45 minutes. (Source: Pressure Cooker Barbacoa)
