Ingredients Needed For Southwest Chicken Pasta

Here’s a list of ingredients needed to make this tasty pasta dish:

  • Rotini pasta – or penne pasta (or really any pasta shape of choice), cooked al dente.
  • Butter – For a rich and creamy sauce.
  • Onion – I prefer yellow onion for a bit of sweetness.
  • Red and green bell peppers – Diced, for color and crunch.
  • Jalapeno pepper – Seeded and diced for a little kick. Adjust amount or omit based on how spicy you like.
  • Corn – Frozen or fresh kernels from three ears of corn.
  • Chicken stock – For a rich and flavorful base. Homemade bone broth would be perfect here.
  • Heavy cream – To make the sauce irresistibly creamy.
  • Cheddar and mozzarella cheese – Shredded, for that melty goodness.
  • Rotisserie chicken – Shredded. Feel free to cook your chicken fresh for this dish.
  • Tortilla chips – Crushed, for a crunchy topping.
  • Pantry staples and seasonings: garlic, all-purpose flour, ground cumin, chili powder, salt and black pepper


  • Protein: Substitute rotisserie chicken with ground beef or ground turkey.
  • Pasta: Try using whole wheat pasta or gluten-free pasta for dietary needs.
  • Cheese: Swap in Mexican cheese blend for a different flavor profile.
  • Vegetables: Add black olives, green chiles, or a can of black beans for more variety.
  • Spice: Use taco seasoning instead of cumin and chili powder for a different twist.

How to Make Southwest Chicken Pasta

For full recipe details, including ingredient measurements, see the printable recipe card at the bottom of this post. Here are step by step directions for making this recipe:

1. Preheat Oven

Preheat oven to 350° F. 

2. Cook Pasta

Bring a large oven safe pot (like a dutch oven) of water to a boil. Salt generously and cook pasta for half the time recommended on the box. Drain and rinse in cold water. Set aside. 

Pro Tip: This can be a one-pot recipe, but if you don’t have a dutch oven or other oven safe pot, feel free to transfer the pasta to a casserole dish and bake as shown in the images.

3. Saute Veggies

In the same hot pot, melt butter and sauté onions, garlic, peppers, jalapeños and corn until tender…about 7 minutes or so. Feel free to reduce or omit jalapeños if sensitive to spicy foods. 

4. Thicken Sauce

Sprinkle in flour and stir. Cook 2 minutes, then pour in chicken stock and whisk. Stir in cumin, chili powder, salt and black pepper. Increase heat to thicken sauce. 

5. Combine

Turn off heat and add mozzarella cheese, one cup of the cheddar cheese, heavy cream, chicken and cooked pasta. Stir to combine.

6. Bake

Top with crushed tortilla chips and the remaining 1/2 cup of cheddar cheese. Bake uncovered for 20-30 minutes or until hot and bubbly. Serve hot.

Storage + Make Ahead Directions

Allow to cool to room temperature. Store in an airtight container in the fridge for up to 3-4 days. Reheat in the oven or microwave until hot.

To Freeze: You can freeze the casserole before or after baking. Cover tightly in an airtight container. Thaw in the refrigerator before baking, and bake as the recipe card indicates.

To Make Ahead: Prepare as directed and store in the fridge up to a day in advance. Bake when ready to serve. If you are making ahead, you likely don’t have room in your fridge to store a dutch oven, ha! So, I would recommend baking in a casserole dish so that it fits in your fridge easier!
