Gather all your ingredients together to streamline the cooking process. Begin by slicing the onion and mincing the garlic. This quick prep work will make it more convenient to layer the flavors into your slow cooker.
Heat olive oil in a skillet over medium heat. Add the chicken breasts and sear until both sides are golden brown, about 3-4 minutes per side. This step enhances flavor depth and locks in the chicken’s juiciness.
In a blender, combine diced tomatoes, chipotle peppers, minced garlic, oregano, cumin, and chicken broth. Blend until smooth. This will be the vibrant, flavorful sauce that coats your chicken.
Place sliced onions in the bottom of the slow cooker. Lay seared chicken breasts on top. Pour the blended sauce over the chicken, ensuring it’s well-coated. Add salt and pepper as per your taste.
Cover and cook on low for 6–8 hours or on high for 3–4 hours. The slow, leisurely cooking process allows flavors to meld beautifully, resulting in tender, fall-apart chicken.
Once cooked, use two forks to shred the chicken right in the sauce. This helps the meat absorb more flavor while creating the classic texture of tinga.
Before serving, squeeze lime juice over the chicken mixture. This brightens up the dish and balances the smoky heat.
