Delicious and tender Barbacoa Beef Tacos featuring slow-cooked, marinated beef chuck roast, crispy golden hash browns, and a creamy avocado cilantro dressing. Perfectly balanced with smoky chipotle flavors and tangy lime, these tacos offer a satisfying Tex-Mex experience ideal for a comforting meal.


Ingredients

Beef & Marinade

  • 2 lbs beef chuck roast, well-marbled
  • 2 dried chipotle peppers
  • 4 cloves garlic
  • 2 tsp cumin
  • Salt, to taste
  • 2 tbsp lime juice (for marinade)

Hash Browns

  • 3 cups frozen hash browns, shredded style

Avocado Cilantro Dressing

  • 2 ripe avocados
  • 1/2 cup sour cream
  • 2 tbsp lime juice
  • 1/4 cup fresh cilantro, chopped

Serving

  • Taco shells for serving


Instructions

  1. Prepare the marinade: Blend chipotle peppers, garlic, cumin, salt, and 2 tablespoons of lime juice together until smooth. Coat the beef chuck roast thoroughly with this marinade. For best flavor, marinate the beef overnight or at least 2 hours before cooking.
  2. Slow-cook the beef: Place the marinated beef in a slow cooker and cook on low heat for about 8 hours until the meat is fork-tender and easily shredded.
  3. Cook the hash browns: While the beef is finishing, cook the frozen shredded hash browns in a skillet over medium heat until they turn golden and crispy.
  4. Make the avocado cilantro dressing: About 30 minutes before serving, blend the ripe avocados, sour cream, remaining 2 tablespoons lime juice, and chopped cilantro into a smooth, creamy dressing.
  5. Assemble the tacos: Warm the taco shells as per package instructions. Layer each shell with crispy hash browns, generous shredded barbacoa beef, and a drizzle of avocado cilantro dressing. Serve immediately for best taste and texture.

Notes

  • For deeper flavor, marinate the beef overnight but a minimum of 2 hours works well.
  • Using well-marbled chuck roast ensures tender juicy meat after slow cooking.
  • You can substitute sour cream with Greek yogurt for a lighter dressing.
  • Warm the taco shells before serving to improve texture and prevent breaking.
  • Leftover beef can be refrigerated for up to 3 days or frozen for up to 2 months.
