Instructions

  • Preheat the oven to 350°F.

  • Add the jumbo shell pasta to the boiling water.
  • Cook the pasta until al dente, according to the package directions.
  • Drain the cooked shells thoroughly.
  • Rinse the shells under cold water to stop the cooking process and make them easier to handle.

  • Arrange the stuffed shells in a single layer in the prepared baking dish, placing them on top of the Alfredo sauce.
  • Spread the remaining Alfredo sauce evenly over the stuffed shells.
  • Cover the baking dish with aluminum foil, if desired, to help keep the shells moist while baking.
  • Bake for 20 to 25 minutes, or until the shells are heated through and the sauce is warm and creamy.
  • Remove the baking dish from the oven.
  • Allow the stuffed shells to rest for several minutes before serving.
  • Serve warm.

Notes

To make Chicken Broccoli Alfredo Stuffed Shells gluten free, replace the jumbo shell pasta with certified gluten-free jumbo shells or another gluten-free pasta shape suitable for stuffing or layering.
Use a gluten-free Alfredo sauce, as some jarred sauces may contain wheat-based thickeners or gluten-containing additives.
Verify that the rotisserie chicken is gluten free, since some store-bought chickens may contain gluten in seasoning blends, marinades, or shared preparation areas.
Confirm that the mozzarella cheese, Parmesan cheese, frozen broccoli, garlic powder, salt, and pepper are labeled gluten free.
Prepare the recipe with clean utensils, bowls, baking dishes, strainers, and serving tools to prevent gluten cross-contact.
