Ingredients
This is meant to be a brief overview of this great recipe. For step-by-step instructions and a full printable recipe card with ingredients, please scroll down to the teal box below.
- Guajillo Chili Powder: I love this seasoning because the heat is mild, and the flavor is tangy with just a little smokiness. Look for it in the seasonings aisle or purchase it online.
- Fresh Garlic: While you can substitute garlic powder in a pinch, fresh garlic will give your tacos more flavor.
- Crushed Tomatoes: The tomatoes add flavor and body to the shredded beef tacos.
- White Vinegar: This will help break down the connective tissue of the beef and provide a little acid to the dish.
- Mexican Oregano: Compared to regular Oregano, this variety is more earthy. It's worth picking up Mexican Oregano if you love authentic Mexican food. In a pinch, you can use regular Oregano as a substitute.
- Beef Roast: I have used chuck roast and top round roast, and I prefer the chuck roast, which has a higher fat content. The chuck roast is more flavorful, shreds very well, and is often a little bit less expensive.
- Beef Broth: You can use beef stock if needed.
- Onions: Finely dice a white onion, which will cook down with the tomatoes and seasonings, adding delicious flavor. Yellow onions or sweet onions will also work.
- Additional Seasonings: Paprika, onion powder, cumin, allspice, cinnamon, salt, and black pepper support the guajillo chili powder and Mexican oregano.
- Tortillas: While corn tortillas are more authentic in Mexican cuisine than flour, the choice is up to you. Personally, my tastebuds prefer corn tortillas. For kids, I like soft flour tortillas because they are a little less delicate.
- Toppings: You can add anything you want on top of your tacos. My family doesn't care for cilantro, so I use chopped parsley. Thinly sliced red onions and chopped tomatoes also add freshness.

Ang's Recipe Tips
- Remove the beef roast from the slow cooker and place it on a cutting board. Use two forks to shred the beef.
- For a smoother sauce, use an immersion blender to puree the cooking liquid.
- After shredding, return the meat to the slow cooker with tongs and toss it to coat the beef.
- Toasting the tortillas adds tons of flavor and really make the tacos something special. Don't skip this step!

Serving Suggestions
Serve the toasted tortillas and slow cooker shredded beef with your favorite taco toppings like guacamole, sour cream, pico de gallo, salsa, or a bit of fresh lime juice.
I love adding crumbled queso fresco or cotika on top of these slow cooker shredded beef tacos. Experiment with cheddar cheese for more heat, pepper jack.
Storage
To Store: Leftover crockpot shredded beef tacos should be stored in an airtight container. Always store tortillas in a separate container, or they will become soggy. (These are my favorite airtight containers.)
To Reheat: Microwave individual portions in 30-second intervals until heated throughout.
To Freeze: Allow the beef mixture to cool completely. Transfer the mixture to a resealable freezer bag. Label and store in the freezer for up to 3 months.
To Thaw: Transfer the bag of frozen beef to the fridge and thaw overnight. For quicker thawing, place the bag into a large bowl with room-temperature water for 1-2 hours.
Leftovers
Use leftover Mexican shredded beef to make quesadillas, enchiladas, burritos, rice bowls, nachos, and more! It can also be used instead of ground beef to make walking taco casserole or beefy cheese dip.
