Layer the base: Add the onion, bell pepper, jalapeño, garlic, beans, corn, crushed tomatoes, and quinoa to the crockpot.
Pour in the chicken broth and stir to combine.
Season generously: Sprinkle in the chili powder, cumin, smoked paprika, oregano, salt, and pepper. Stir well so the spices are evenly distributed.
Add the chicken: Nestle the chicken breasts into the mixture, making sure they’re submerged. This helps them cook evenly and stay tender.
Cook low and slow: Cover and cook on Low for 6–7 hours or on High for 3–4 hours, until the chicken is cooked through and the quinoa is tender.
Shred the chicken: Remove the chicken to a cutting board and shred with two forks.
Return it to the crockpot and stir to combine.
Adjust thickness: If the chili is thicker than you like, stir in an extra 1/2–1 cup of broth. If it’s too thin, let it cook uncovered on High for 15–20 minutes.
Brighten it up: Stir in the lime juice. Taste and adjust salt, pepper, or chili powder as needed.
Serve and top: Ladle into bowls and finish with your favorite toppings.
A little cheese, a dollop of yogurt, and a handful of cilantro go a long way.
