You don't even have to boil the pasta, cook the chicken, or sauté the vegetables! Just stir everything together and 10 minutes later you'll have a Dump-and-Bake Creamy Chicken Penne Pasta that's ready for the oven. It's a one pot meal that makes weeknight dinners easy!
Cooking for a larger family? I recommend doubling all of the ingredients and preparing the casserole in a 9 x 13-inch baking dish. The baking instructions remain the same.
