Recipe Instructions

Step 1

Preheat oven to 350 degrees F (175 degrees C). Prepare a 13x9-inch baking dish with nonstick cooking spray.

Step 2

Melt butter in a heavy saucepan over medium heat. Cook and stir onions, celery, and bell pepper in melted butter until softened, about 5 minutes.

Step 3

Bake in preheated oven until cheese is melted and beginning to brown, about 25 minutes.

Step 4

Bring a large pot of lightly salted water to a boil. Cook rotini at a boil until tender yet firm to the bite, about 8 minutes; drain. Pour rotini into prepared baking dish.

Step 5

Stir milk, cream of mushroom soup, poultry seasoning, salt, and black pepper into onion mixture. Reduce heat to medium-low and bring to a simmer; about 5 minutes. Add chicken and 1/2 cup Cheddar cheese to milk mixture; remove immediately from heat and pour over rotini. Top pasta and sauce mixture with remaining Cheddar cheese.
