I got this recipe from a set of recipe cards and it is one of the favorites in my house. I admit that I never follow this 100% (I don't add the onions, and I don't exactly measure the cheese and spices) but I will print the exact recipe here.
Preheat the oven to 350°F Start cooking pasta according to directions and drain. While pasta is cooking --.
Cut chicken into strips, bites, or pieces. Sprinkle with salt and pepper.
Heat oil in large skillet over medium heat.
Add the chicken to skillet and cook until no longer pink, about 6 minutes. Remove chicken from skillet with a slotted spoon and set aside.
Add onion and garlic to skillet and cook until onion is softened (I'm not sure how long -- I never use onion) Stir in pasta sauce and increase heat to high. Bring sauce to a boil, reduce heat to medium low and simmer for 5 minutes.
Add the chicken, cream and basil to the skillet and mix well.
Spoon cooked pasta into an ungreased 13 X 9 baking pan. Spoon the pasta sauce mixture (with chicken) over the top. Sprinkle with the cheeses. Bake about 25 minutes, until bubbly and cheese is lightly browned.
