Recipe type: Slow Cooker-Dinner
Cuisine: Mexican
Serves: 12
  • 3-4 pounds of uncooked chicken breasts
  • 1 large or two small onions, yellow, white or purple
  • 1 large red pepper
  • 1 large green pepper
  • 3 tbsp cornstarch
  • 2 Tbsp chili powder
  • 1 Tbsp paprika
  • 1 Tbsp sugar
  • 1 Tbsp salt
  • 2½ tsp chicken bouillon
  • 1½ tsp onion powder
  • ½ tsp ground cumin
  • ½ tsp garlic powder
  • ½ tsp smoked paprika
  • ⅛ tsp red pepper flakes
  • ***2 tbsp olive oil if you cook your peppers in a frying pan instead of adding them to the chicken in the slow cooker.
  1. In a small mixing bowl, combine the corn starch, chili powder, paprika, sugar, salt, chicken bouillon, onion powder, ground cumin, garlic powder, smoked paprika and red pepper flakes. Mix well and set aside.
  2. Place chicken breasts in the slow cooker, and sprinkle with 2 tbsp of the seasoning mix per lb of chicken you use. Cover with lid and cook for 6 hours on low or 4 hours on high.
  3. If you want, you can add the sliced peppers and onions while the chicken is cooking. If cooking on low you add them with two hours left to cook. If cooking on high you add them the last hour. Toss the peppers and onions in 2-3 tbsp of seasoning before adding them in to cook with the chicken.
  4. I prefer to saute the peppers and onions in a large frying pan rather than cook them with the chicken, because I like the texture of them better that way. If you want to do that too, just pour two tbsp of olive oil in the bottom of a large frying pan. Add peppers and onions, season with 2-3 tbsp of the seasoning mixture, and stir and saute until they are tender or your desired done-ness.
  5. Serve with tortillas, grated cheese, pico de galo, guacamole and any other desired toppings.
  6. We also like to serve Spanish Rice with this meal.
