  • 1 (12 ounce) package jumbo pasta shells
  • 2 cups cooked, shredded chicken (such as from a rotisserie chicken)
  • 1 (10 ounce) box frozen chopped spinach, thawed and squeezed dry
  • 1 (15 ounce) container ricotta cheese (about 1 ¾ cups)
  • 2 cups (8 ounces) shredded mozzarella cheese, divided
  • ¼ cup grated Parmesan cheese
  • 1 egg
  • 1 tablespoon chopped fresh basil (or 1 teaspoon dried basil)
  • ½ teaspoon salt
  • ½ teaspoon garlic powder
  • Pinch of nutmeg
  • 2 cups Alfredo sauce (I used one 15-ounce jar plus part of a second jar)


  • Preheat oven to 350°F. Spray a 9 x 13-inch dish with cooking spray. Pour 1 cup of the Alfredo sauce into the bottom of the dish. Save the rest of the sauce for later.
  • Cook pasta in a large pot of salted boiling water according to package instructions. Drain and rinse under cold water.
  • In a large bowl, combine the chicken, spinach, ricotta, 1 ½ cups of the mozzarella, Parmesan, egg, basil, salt, garlic powder and nutmeg.
  • Stuff each shell with the chicken mixture. Depending on how full you stuff each shell, you might not need all of the shells in the box. I can typically fill and fit about 20-22 shells in my pan. If you have extra shells and stuffing, you can assemble them in a small dish and save it for another meal (or bake it at the same time as the larger dish).
  • Arrange stuffed shells in the prepared baking dish, open side up. Pour remaining 1 cup of Alfredo sauce over top. Sprinkle with remaining ½ cup of mozzarella.
  • Cover with foil and bake for about 30 minutes, or until heated through. Remove the foil cover during the final 5-10 minutes to allow the top to get a little bit crisp.


  • Cook the pasta shells just until barely al dente, since they will continue to cook in the oven. You don't want to end up with overdone, mushy pasta!
  • Rotisserie chicken is a great shortcut, and it adds nice flavor to the dish. If you prefer, you can boil about 1 lb. of boneless, skinless chicken breasts or thighs to use in this dish instead.
  • Squeeze the spinach really dry by wringing it out in an old dish cloth. You'll be surprised by how much water comes out!
  • Garnish the shells with fresh herbs like parsley or basil for a bright finishing touch.
  • How many stuffed shells per person? I generally assume about 2-3 shells per person. Larger appetites might like 4, while smaller eaters may prefer 2. This recipe yields about 20-22 stuffed shells, and it typically feeds about 6-8 people.
