Start by placing the chicken breasts or thighs in the slow cooker. If they are thick, pound them gently to an even thickness to ensure they cook uniformly.
In a bowl, mix together the fresh squeezed orange juice, fresh squeezed lime juice, smashed garlic cloves, chopped chipotles with adobo sauce, chopped jalapeño, cumin, chili powder, oregano, salt, and pepper. Pour this mixture over the chicken in the slow cooker.
Pour in the Coca-Cola, which will help to tenderize the chicken and add a unique flavor. Toss in the bay leaves for added aroma.
Cover the slow cooker and cook on low for 6-8 hours or high for 4-5 hours. The chicken should be tender and easily shredded when it’s done.
Once cooked, remove the chicken from the slow cooker and shred it using two forks or tongs. Discard the bay leaves and return the shredded chicken to the slow cooker, mixing it with the remaining juices for extra flavor.
Serve your Slow Cooker Chicken Carnitas in warm tortillas, over rice, or in burritos. Top with your favorite garnishes like cilantro, diced onions, or avocado for a fresh finish.
