Slow Cooker Barbacoa (The Easiest Shredded Beef Tacos)

This is one of those meals that feels like you put in way more effort than you actually did.

Tender, juicy, fall-apart beef, slow cooked in bold, smoky spices… and all you have to do is throw everything in the slow cooker and walk away.

It’s the kind of dinner that works just as well for a busy weekday as it does for having people over—because it’s low effort, but always a hit.

  • Makes amazing leftovers (arguably better the next day)
  • Perfect for tacos, bowls, nachos, or wraps
  • Freezer-friendly

Ingredients

  • 2 lbs beef chuck
  • 1 tbsp olive oil
  • 6 garlic cloves, minced
  • 1 yellow onion, diced
  • 2-3 chipotle peppers in adobo, chopped
  • 2 tbsp adobo sauce (from the can)
  • 2 tbsp tomato paste
  • 3 tbsp fresh squeezed lime juice
  • ½ cup fresh squeezed orange juice
  • 1 can of tomatoes
  • 1 cup beef broth
  • 1 tbsp cumin
  • 1 tbsp oregano
  • 1 tbsp paprika
  • ½ tbsp onion powder
  • ½ tbsp garlic powder
  • ¼ tsp allspice
  • ½ tsp salt (to taste)

Instructions

1. Optional: Sear the Beef

Heat olive oil in a pan over medium-high heat and sear the beef on all sides.

This step adds extra depth of flavor—but if you’re short on time, you can skip it.


2. Add to Slow Cooker

Place the beef in the slow cooker and add all remaining ingredients on top.


3. Cook Low and Slow

Cook on:

  • Low for 8 hours or
  • High for 4–5 hours

The beef should be incredibly tender and easy to shred.


4. Shred

Remove the beef, shred with two forks, then return it to the sauce and mix well.

Let it sit for 10–15 minutes to soak up all that flavor.


How to Serve

We almost always use this for tacos, but it’s super versatile.

Tips for the Best Barbacoa

  • Chuck roast is key – it gets the most tender
  • Don’t skip the chipotle + adobo—it’s where the flavor comes from
  • Taste and adjust salt at the end
  • Let the shredded beef sit in the juices before serving

Storage & Freezing

  • Fridge: Up to 4 days in an airtight container
  • Freezer: Freeze in portions with some of the sauce for up to 2–3 months

Reheat gently on the stove or microwave with a splash of broth if needed.
