Ingredients
Meat
- 3 pounds beef chuck roast, cut into 2-inch chunks (or use beef brisket)
Peppers and Sauces
- 2 guajillo peppers
- 2 ancho peppers
- 7 ounce can chipotles in adobo (optional, for extra saucy and tangy-smoky flavor)
Liquids & Oils
- 2 tablespoons olive oil
- 1.5 cups beef broth
- 1/4 cup apple cider vinegar
- Juice from 1 large lime (about 1/4 cup)
Vegetables & Aromatics
- 1 large onion, chopped
- 4 cloves garlic, chopped
Spices & Seasonings
- 1 tablespoon Mexican oregano (or regular oregano)
- 2 teaspoons cumin
- 1 bay leaf
- Salt and ground black pepper to taste
Instructions
- Soften Peppers: Remove stems and seeds from guajillo and ancho peppers. Place dried chiles in a large bowl and cover with very hot or boiling water. Soak for 15 minutes until soft and rehydrated. Drain and discard water.
- Make Pepper Paste: Add softened peppers to a food processor with chipotles in adobo sauce and a pinch of salt. Process until smooth paste is formed.
- Season Beef: Place beef chunks in a bowl and toss with the ancho-guajillo pepper paste to coat evenly.
- Brown Beef: Heat olive oil in a large cast iron pan over medium-high heat. Sear beef chunks for a few minutes on each side until nicely browned. Transfer beef to a slow cooker.
- Deglaze Pan: Pour a bit of beef broth into the hot pan to loosen browned bits, scraping the bottom with a spoon. Pour this flavorful liquid into the slow cooker with the beef.
- Add Remaining Ingredients: Add remaining beef broth, apple cider vinegar, lime juice, chopped onion, garlic, Mexican oregano, cumin, bay leaf, salt, and pepper to the slow cooker. Stir everything to combine.
- Slow Cook: Cook on high for 4 hours or on low for 6-8 hours, until beef is fork-tender and easily shreddable. Cooking times may vary depending on your slow cooker.
- Shred the Beef: Use two forks to shred the beef directly in the slow cooker. Serve as desired in tacos, burritos, or bowls.
Notes
- Removing seeds from dried peppers reduces bitterness and controls heat level.
- Using chipotles in adobo is optional but adds extra smoky and tangy flavor.
- You can substitute beef chuck roast with brisket if preferred.
- Searing beef before slow cooking adds depth of flavor through caramelization.
- Cooking times may vary based on the size of beef chunks and your slow cooker model.
- Leftover barbacoa can be refrigerated for up to 3 days or frozen for up to 3 months.
- Serve with warm tortillas, fresh cilantro, onions, and lime wedges for a classic experience.
