Place the chicken breasts into the crockpot and sprinkle evenly with taco seasoning, ensuring all sides are coated well. This helps infuse the meat with flavor as it cooks.
Add the sliced onion and bell pepper on top of the chicken. Their fragrant aromas will meld with the spices, creating a savory base for the dish.
Cover the crockpot with the lid and set it to low. Let it cook undisturbed for 4 hours, during which you’ll hear gentle bubbling and smell the seasoned meat filling your kitchen with a warm aroma.
Once the cooking time is up, use two forks to shred the chicken directly in the crockpot. It should be tender and easily pulled apart, with juices still clinging to the meat.
Squeeze fresh lime juice over the shredded chicken and stir gently to combine. This brightens the flavors and adds a zesty kick to the dish.
Warm your tortillas and sprinkle shredded cheese on top of the hot, seasoned chicken filling. Let the cheese melt slightly for a gooey, flavorful topping.
Serve the shredded chicken tacos hot, with your favorite sides or toppings, and enjoy a tender, flavorful bite with every chew.
