01 - Lightly grease the insert of your slow cooker with olive oil to prevent sticking.
02 - Place the chicken breasts in a single layer at the bottom of the slow cooker insert.
03 - In a medium mixing bowl, combine the chopped onion, minced garlic, jalapeño, cilantro, lime juice, chicken broth, cumin, chili powder, salt, pepper, and smoked paprika. Stir until well blended.
04 - Pour the cilantro-lime mixture evenly over the chicken breasts, ensuring they are well coated on all sides.
05 - Cover the slow cooker and cook on low for 4 to 5 hours, or until the chicken is tender and easily pierced with a fork.
06 - Using two forks, shred the chicken directly inside the slow cooker, tossing it thoroughly in the accumulated juices.
07 - Taste the shredded chicken and adjust seasoning as needed. Serve hot, garnished with additional chopped cilantro and fresh lime wedges.
