Equipment

  • Large mixing bowl
  • Saucepan
  • Cookie sheet
  • Parchment paper
  • Large spoon
  • 9x13-inch baking dish

Ingredients
  

Stuffed Shells

  • ½ tsp garlic powder
  • 1 box jumbo Shells
  • 2 cups cooked, shredded chicken
  • 1 cups shredded Mozzarella cheese
  • 1 bag of frozen broccoli florets steamed then chopped
  • ½ cup shredded Parmesan cheese
  • 1 salt and pepper to taste

Sauce

  • cups whole milk
  • 3 tbsp salted butter
  • ¾ cup shredded Mozzarella cheese
  • 1 cup heavy cream
  • 3 cloves garlic minced
  • cups shredded Parmesan cheese

Instructions
 

  • Prepare Alfredo sauce by combining butter, garlic, heavy cream, and milk in a saucepan over medium heat.
  • Bring the mixture to a simmer, then remove from heat and stir in Parmesan and Mozzarella cheese.
  • Season with pepper, if desired.
  • Cook pasta shells according to the package instructions until al dente.
  • Drain the water, then arrange the shells on a parchment-lined cookie sheet to cool completely.
  • In a large bowl, combine cooked chicken, garlic powder, salt, pepper, and chopped broccoli.
  • Add 1 cup of the prepared Alfredo sauce to the chicken mixture and stir until well combined.
  • Grease a 9×13-inch baking dish.
  • Fill each cooled pasta shell with a generous spoonful of the chicken and broccoli mixture.
  • Arrange them in the baking dish.
  • Pour the remaining Alfredo sauce evenly over the stuffed shells.
  • Top with additional Mozzarella and Parmesan cheeses, then bake uncovered at 350°F for 25 minutes or until bubbly.
  • Serve hot!

Notes

  • Make sure to cook the shells just until al dente; overcooked shells may tear during stuffing.
  • Fresh or frozen broccoli works well; just make sure to chop it finely.
  • Letting the shells cool completely before stuffing helps them hold their shape.
