Place the chicken in a slow cooker insert. I use a 5 quart.
2 ½-3 pounds boneless skinless chicken breasts1
Season the chicken with salt.
1 teaspoon kosher salt
In a medium saucepan, stir remaining ingredients together until combined.
1 cup ketchup, 2 tablespoons brown sugar, 2 tablespoons molasses, 2 tablespoons Worcestershire sauce, 2 teaspoons adobo chile sauce2, 1 tablespoon cider vinegar, 2 cloves garlic, 1 teaspoon smoked paprika, 1 teaspoon ground black pepper, ½ teaspoon dry mustard
Heat over medium-low sauce just until sauce begins to bubble, stirring regularly.
Remove sauce from heat, and pour over chicken breast.
Cover, and cook over LOW for 4-5 hours, or until chicken shreds easily with 2 forks.
Turn slow cooker to WARM, and let shredded chicken sit in sauce for 30 minutes before serving.
Notes
I recommend using regular-sized chicken breasts. Chicken halves or chicken breast filets can dry out while cooking.
This is the sauce from canned chipotle peppers in adobo sauce. The sauce is not spicy. However, if you would like to add more heat to the sauce, add more adobo sauce or use the chipotle peppers.
