Prep the base: Add the diced tomatoes, black beans, corn, chopped onion, garlic, and chicken broth to the slow cooker. Sprinkle in taco seasoning, cumin, smoked paprika, salt, and pepper.
Stir to combine.
Add the chicken: Nestle the chicken breasts (or thighs) into the mixture, ensuring they’re mostly submerged.
Cook low and slow: Cover and cook on Low for 4–6 hours or High for 2.5–3.5 hours, until the chicken is tender and easily shreds. Low is best for juicier results.
Shred the chicken: Remove the chicken to a plate and shred with two forks. Return the chicken to the slow cooker and stir to coat in the sauce.
Brighten it up: Stir in the lime juice.
Taste and adjust seasoning with more salt, pepper, or taco seasoning if needed.
Build your bowls: Spoon chicken mixture over warm rice. Add toppings like cheese, avocado, cilantro, a dollop of sour cream, and a squeeze of lime. Finish with salsa or hot sauce if you want heat.
