Ingredients

Chicken Thighs: Boneless, skinless thighs are best since they stay juicy during baking. Choose evenly sized pieces so they cook at the same rate.
Taco and Ranch Seasoning: Together, they form a quick Southwest chicken seasoning that delivers bold, smoky, and tangy flavor.
Buttermilk: The slight acidity tenderizes the chicken and keeps it extra moist. If you don’t have buttermilk, mix milk with lemon juice as a quick substitute.
Flour Tortillas: Soft tortillas make serving easy and fun. Warm them before filling so they’re pliable and don’t tear. You can use any leftovers for breakfast with my mountain man breakfast recipe!

Southwest Chicken Skillet: After baking, slice the chicken and sauté it with bell peppers, onions, and black beans in a skillet. Top with shredded cheese and a sprinkle of cilantro for a one-pan meal that's both quick and satisfying.
Southwest Chicken with Pineapple: Add chunks of fresh or canned pineapple to the tortillas or skillet for a sweet and tangy twist that pairs well with the smoky chicken seasoning. Love pineapple? Try my pineapple cherry dump cake for an easy sweet treat.

How to Make Southwest Chicken

This Southwestern chicken recipe is packed with flavor but simple enough for a weeknight meal. Before you start, preheat the oven to 400°F and have a Dutch oven or an oven-safe pan ready for searing and baking.

Expert Tips

Marinate for Maximum Flavor: Allow the chicken to marinate for at least 2 hours, or up to 24 hours, so the southwest chicken seasoning infuses every bite with rich, bold flavor.
Sear for Texture: Searing the marinated chicken thighs before baking creates a golden crust and helps lock in juices, keeping the chicken tender.
Cooking the Chicken: Pour the buttermilk around the chicken instead of on top, and bake covered. This keeps the chicken moist without washing away the seasoning.
Storing Leftovers: Keep any cooked chicken in an airtight container in the fridge for up to 3 days, or you can freeze it for up to 3 months.

Recipe FAQs

Can I freeze Southwest Chicken?

Yes, cooked Southwest Chicken freezes well. Let it cool completely, then store it in an airtight, freezer-safe container for up to 3 months. Reheat gently in the oven or skillet to keep it tender and flavorful. Add a bit of broth during reheating to keep it juicy.

Can I use chicken breasts instead of thighs for this Southwest chicken recipe?

Yes, you can substitute boneless, skinless chicken breasts, but they may cook faster and can dry out more easily. Reduce the baking time slightly and check the internal temperature to keep them moist and juicy.

How can I keep the chicken from sticking to the pan?

Make sure to use enough butter or oil when searing, and don’t move the chicken too early. Let it naturally release from the pan once it forms a crust.
