Beef Barbacoa:

  • 2 lbs. approx Boneless Beef Roast
  • Salt + Pepper
  • 2-4 Chipotle Peppers in adobo sauce finely diced
  • 2 Tablespoons Fresh Lime Juice
  • 1 Tablespoon Cumin
  • 1 Tablespoon Chile Powder
  • 1 teaspoon Garlic Powder
  • 12 ounce can Beef Broth
  • 1 pkg. Corn Tortillas

Pepper Jack Queso:

  • 1 1/2 Tablespoons Butter
  • 2 Jalapeno Peppers finely diced and deseeded, if you want it mild
  • 2 Garlic Cloves minced or 1/2 teaspoon Garlic Powder
  • 1 1/2 Tablespoons Flour
  • 3/4 cup Milk
  • 4 1/2 cups Monterey Jack Cheese shredded


  • Fresh Avocado
  • Cilantro
  • Pickled Jalapenos
  • White Onion
  • Fresh Lime


  1. Generously season beef roast with salt and pepper. Place in slow cooker.
  2. In small bowl, mix together chipotle peppers, lime juice, cumin, chile powder, and garlic powder. Spread all over both sides of beef roast and pat. Pour beef broth around roast avoiding top so the spices stay put.
  3. Cook for 8-10 hours on low setting. Shred with two forks. Return to slow cooker and let it soak up the juices until ready to serve.
  4. Pepper Jack Queso:
  5. Melt butter in cast iron skillet or saucepan over medium-low heat. Add jalapenos and cook for about 4-5 minutes until peppers start to become tender. Add garlic and cook for 1 minute. Whisk the flour into the butter and cook for 30 seconds.
  6. Add the milk, whisking constantly until sauce is thick, about 5 minutes.
  7. Turn heat to low, and add cheese slowly, 1/4 cup at a time, stirring into the sauce until completely melted. Repeat until all cheese is added.
  8. Serve queso right away. If it sets up too much, place back on stovetop and add a dash of milk or butter and stir.
  9. To assemble tacos:
  10. Place shredded Barbacoa Beef into corn tortilla. Drizzle pepper jack queso over beef. Top with sliced, fresh avocado, cilantro, lime, white onion, and pickled jalapenos (optional).
