Add the uncooked rotini pasta, diced tomatoes (with juice), chicken broth, barbecue sauce, and shredded chicken to the skillet. Stir everything together, ensuring that the pasta is submerged in the liquid.
Increase the heat and bring the mixture to a boil. Once boiling, reduce the heat to low, cover the skillet, and let it simmer. Stir occasionally until the pasta is tender and has absorbed most of the liquid, approximately 15-20 minutes.
Once the pasta is fully cooked, sprinkle the shredded colby jack cheese evenly over the top. Cover the skillet with a lid and let it sit for 2-3 minutes, or until the cheese melts.
Drizzle with additional barbecue sauce if desired, and serve hot. Enjoy your flavorful One Skillet BBQ Cheesy Chicken Pasta!
Notes
Watch the liquid and avoid overcooking the pasta for best results. Customize seasoning as desired.
