Ingredients

  • 1 (16 ounce) package uncooked rotini pasta
  • 22 oz jar Alfredo sauce (about 1 very large 22-ounce jar or 1 ½ 15-ounce jars) (approximately 2 ½ cups total)
  • 3 cups chicken stock (or sub with chicken broth)
  • 2 cups diced or shredded rotisserie chicken (or other diced cooked chicken)
  • 2 teaspoons minced garlic  (about 2 large cloves)
  • 2 cups shredded Mozzarella cheese (or Italian blend cheese)
  • Optional garnish: Parmesan cheese and chopped fresh herbs, such as basil, oregano, or parsley

Instructions

    Cup of Yum
  1. Preheat oven to 425°F (220°C). In a large baking dish, stir together uncooked pasta, Alfredo sauce, chicken stock, chicken and garlic. Cover tightly with aluminum foil and bake for 30 minutes.
  2. Uncover; give the pasta a good stir. At this point you should check the pasta to make sure that it is al dente (firm but with a tender bite). I have had good luck with the 30-minute cook time; however, some readers have noted that it required about 10 or 15 minutes longer. If it’s still too hard after 30 minutes, just cover the dish and return to the oven until pasta is al dente. Then move on to the next step. Sprinkle mozzarella over the top.
  3. Bake, uncovered, for 8-10 more minutes, or until the cheese melts. Garnish with freshly grated Parmesan or fresh chopped herbs if desired.

Notes

  • This recipe is specifically designed and tested with rotini pasta. If you don’t have rotini, you can substitute with other short pasta shapes like penne, rigatoni, or elbows. Just pick a pasta that has a similar cooking time as the rotini (about 7-8 minutes recommended on the package) — otherwise you’ll need to adjust the casserole’s baking time in the oven.
  • Total cooking time will vary depending on the type of pan that you use and your individual oven. Glass or ceramic baking dishes will take longer than metal pans, for instance. To know when your casserole is done, taste a bite of the pasta. The noodles should be tender and most of the liquid should be absorbed.
