FAQs
Can I use chicken thighs instead of chicken breasts?
Yes, you can substitute boneless, skinless chicken thighs for chicken breasts. They may be a bit juicier and more flavorful. If you use bone-in chicken, increase the cooking time by about 30 minutes on the low setting.
Can I add other vegetables to this recipe?
Absolutely! Feel free to add vegetables like zucchini, bell peppers, or spinach. If using spinach, add it during the last 30 minutes of cooking to prevent it from overcooking.

Interesting choice of ingredients. Reminds me of a traditional dish served during the Renaissance but with a modern twist.
Gotta say, slow cooker is a game changer for meats. This chicken recipe is going in my regular rotation.
