Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 box jumbo pasta shells (about 12 ounces)
2 boneless, skinless chicken breasts, diced into small cubes
1 cup fresh broccoli florets, cut into small bite-sized pieces
1 cup shredded mozzarella cheese
1/2 cup shredded Parmesan cheese
1/4 cup grated Parmesan cheese
1/4 block cream cheese (2 ounces), softened
1 cup unsalted butter (2 sticks, divided)
1 tablespoon minced garlic
16 ounces heavy whipping cream
1 tablespoon garlic powder
1 tablespoon onion powder
1 tablespoon Sazon seasoning
1 tablespoon Creole seasoning
1 teaspoon smoked paprika
1 teaspoon Italian seasoning
1 teaspoon salt
1 tablespoon black pepper
1 tablespoon olive oil
Directions
Marinate the Chicken
In a large bowl, combine diced chicken with olive oil, garlic powder, onion powder, Sazon seasoning, Creole seasoning, smoked paprika, Italian seasoning, salt, and black pepper. Mix thoroughly and refrigerate for at least 30 minutes.
Cook the Chicken and Broccoli
In a large skillet over medium heat, melt 1/2 cup of butter. Add the marinated chicken and cook for 6 to 7 minutes, or until golden brown and fully cooked. Remove the chicken and set aside. In the same pan, lightly sauté the broccoli for 2 to 3 minutes until slightly tender but still bright green. Remove and set aside.
Prepare the Alfredo Sauce
In the same skillet, melt the remaining 1/2 cup butter over medium heat. Add minced garlic and sauté for about 30 seconds until fragrant. Pour in the heavy cream and add the cream cheese. Stir continuously until the cream cheese fully melts and the sauce begins to thicken. Add grated Parmesan cheese and stir until smooth and creamy.
Cook the Pasta Shells
Bring a large pot of salted water to a boil. Cook jumbo shells according to package directions until al dente. Before draining, reserve 1/2 cup of pasta cooking water. Drain and lay shells flat to prevent sticking.
Prepare the Filling
In a large mixing bowl, combine cooked chicken, broccoli, shredded mozzarella, shredded Parmesan, and 1 cup of Alfredo sauce. Mix until evenly combined.
Stuff the Shells
Preheat the oven to 375°F (190°C). Spread a layer of Alfredo sauce on the bottom of a baking dish. Fill each shell generously with the chicken mixture and arrange them in the dish.
Bake
Pour remaining Alfredo sauce over the stuffed shells. Sprinkle extra mozzarella and a light dusting of Italian seasoning on top. Bake uncovered for 15 minutes, or until bubbly and lightly golden on top.
Serve
Allow the dish to rest for 5 minutes before serving. Serve warm and enjoy.
For a seafood twist, substitute the chicken with cooked shrimp and reduce baking time slightly.
For a lighter version, use half-and-half instead of heavy cream and reduce the butter by half.
Add spinach along with the broccoli for extra greens and color.
Use rotisserie chicken to save time on busy weeknights.
If jumbo shells are unavailable, substitute with manicotti or cannelloni and adjust the filling amount accordingly.
Storage/Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days.
To reheat, place portions in an oven-safe dish, cover with foil, and warm at 350°F for about 15 to 20 minutes. You may add a splash of milk or reserved pasta water to keep the sauce creamy.
For microwave reheating, heat in 60-second intervals, stirring gently between each interval until warmed through.
You can also freeze the assembled, unbaked shells for up to 2 months. Thaw overnight in the refrigerator before baking.
FAQs
Can I prepare this dish ahead of time?
Yes. Assemble the stuffed shells, cover tightly, and refrigerate for up to 24 hours before baking.
Why should I marinate the chicken?
Marinating allows the seasonings to fully absorb into the chicken, giving deeper flavor throughout the dish.
How do I prevent the pasta shells from tearing?
Cook them just until al dente and handle them gently when draining and filling.
Can I use frozen broccoli?
Yes, but thaw and pat it dry first to avoid excess moisture in the filling.
What can I use instead of cream cheese?
You can substitute mascarpone or ricotta cheese for a similar creamy texture.
Why is my Alfredo sauce too thick?
Add small amounts of reserved pasta water or milk to loosen the sauce to your desired consistency.
Can I make this dish gluten-free?
Yes, simply use gluten-free jumbo pasta shells.
How do I know when the dish is done baking?
The cheese on top should be melted and bubbly, and the edges should lightly brown.
Can I add extra vegetables?
Absolutely. Spinach, mushrooms, or bell peppers work well in this recipe.
Is this recipe suitable for freezing after baking?
Yes. Allow it to cool completely, wrap tightly, and freeze. Reheat covered in the oven until heated through.
