Step 1

Preheat the oven to 350 degrees F. Then grease a baking dish or casserole. You can equally use a cooking spray. Set aside.

Step 2

Start by boiling pasta in a large pot according to package instructions. Drain and place in a large bowl together with sweet corn, black beans, green chiles, shredded chicken, salsa, green onions, and ½ of the cheese.

Step 3

In a small bowl, add onions, butter, and garlic, and microwave for about a minute. Then transfer into a medium bowl together with sour cream, chili powder, smoked paprika, and cumin. Thoroughly mix.

Step 4

Transfer the spice mixture to the bowl of pasta and fully combine.

Step 5

Spread the chicken pasta mixture into the prepared pan and top with the remaining cheese. Bake for 30 minutes, or until casserole is bubbly and heated through. Serve with tortilla chips, if desired.
