Why You’ll Love This Recipe
This recipe shines for its simplicity and ability to satisfy crowds without fuss. What sets it apart is the effortless blend of spices that give the chicken a deep, rich flavor while the slow-cook process ensures tender, juicy meat. Ideal for meal prepping, it provides tasty options for lunches and dinners throughout the week. Plus, who doesn’t love the ease of a one-pot meal?
Ingredients Notes
The heart of this dish lies in its fresh ingredients. Opt for organic chicken breast if possible to ensure the best taste and texture. You can easily find taco seasoning at any grocery store, but for a flavor boost, mix your own using paprika, cumin, and oregano. If fresh lime isn’t on hand, bottled lime juice will suffice in a pinch. Feel free to use frozen corn as a substitute for fresh kernels.
Recipe Steps
Step 1
Begin by seasoning the chicken breasts with taco seasoning. Place the chicken at the bottom of the slow cooker, and ensure it becomes completely covered with the spiced blend.
Step 2
Add diced tomatoes, black beans, and corn over the chicken. Pour lime juice and chicken broth into the mix, ensuring even distribution throughout the slow cooker.
Step 3
Set the slow cooker to low and let it work its magic for 6 to 7 hours. You can also set it on high for 3 to 4 hours if you’re short on time.

Step 4
Once the cooking time is up, use two forks to shred the chicken directly in the pot. Stir well to combine the shredded chicken with the juices and vegetables.
Step 5
Warm your choice of corn or flour tortillas on a skillet. Serve the slow-cooked filling wrapped in the tortillas with optional toppings like avocado slices, sour cream, and fresh cilantro.
Storage Options
Leftover chicken can be stored in an airtight container in the refrigerator for up to 4 days. For longer storage, distribute the chicken mixture into freezer-safe bags and freeze for up to 3 months. To reheat, thaw in the refrigerator overnight and warm in a skillet or microwave before serving.
Variations & Substitutions
For a lower-carb option, replace tortillas with lettuce leaves for a taco salad. You can switch up the protein by using turkey breast or pulled pork, and for a vegetarian twist, substitute chicken with tofu or extra beans for extra fiber and protein.
Serving Suggestions
These tacos are versatile, perfect for a family meal or casual get-togethers. Add a side of Mexican rice or a simple black bean salad to complete the meal. It’s also an excellent dish for potlucks and informal parties.
