Preheat your oven to a warm 350°F.
Bring a large pot of water to a vigorous boil. Add your pasta and cook it for two minutes less than what the package suggests. Once done, drain it and set it aside.
In a large mixing bowl, whisk together the sour cream, salsa, and taco seasoning until they form a smooth blend.
Now, it’s time to invite the chicken, black beans, corn, and a cup of cheese into the bowl. Stir these delightful ingredients until everything is evenly combined.
Gently fold in the cooked pasta, ensuring it’s well coated with the mixture. Transfer this luscious concoction into a large casserole dish.
Top it off with the remaining cheese, making sure to cover everything generously.
Slide it into the oven and bake for about 20 to 25 minutes, or until the cheese bubbles and turns to a lovely golden color, bringing your casserole to life.
Serve this hot, and get ready to enjoy a fiesta of flavors!
