Ingredients

  • Cooked chicken breast shredded or diced: lean protein that keeps the filling hearty
  • Ricotta cheese: adds a creamy texture and mild flavor essential to the filling
  • Mozzarella cheese shredded: melts beautifully for a gooey, stringy finish
  • Parmesan cheese grated: brings a sharp, nutty flavor that enhances depth
  • Egg: binds the filling together for easy stuffing
  • Fresh parsley chopped: adds freshness and balances richness
  • Garlic powder and onion powder: boost the savory notes without overpowering
  • Unsalted butter: creates the rich base of the garlic butter sauce
  • Minced garlic fresh: is key for an aromatic, vibrant sauce
  • All-purpose flour: for thickening the sauce into a smooth roux
  • Whole milk or half-and-half: adding creaminess; half-and-half makes it even richer
  • Chicken broth: adds another layer of savory flavor
  • Italian seasoning: infuses herbaceous warmth
  • Olive oil: keeps pasta shells from sticking post boiling
  • Salt and pepper: essential for seasoning every component
  • Jumbo pasta shells also called conchiglioni: their size makes stuffing easier and holds plenty of filling
  • Fresh herbs like parsley or basil for garnish: create a bright finishing touch

Step-by-Step Instructions

Cook the Pasta Shells:
Bring a large pot of salted water to a boil. Add the jumbo pasta shells and cook according to package directions, usually about nine to ten minutes until just tender but still firm to the bite. Drain and rinse the shells under cool water to stop the cooking process and prevent sticking. Toss with a tablespoon of olive oil and set aside to cool while preparing the filling.
Prepare the Chicken Filling:
In a large mixing bowl, combine the ricotta, shredded mozzarella, Parmesan, egg, chopped parsley, garlic powder, onion powder, salt, and pepper. Stir together until you have a smooth, well-combined mixture. Gently fold in the shredded cooked chicken making sure it is evenly mixed throughout. Taste the mixture and adjust seasoning if needed. Cover and refrigerate until ready to assemble.
Make the Garlic Butter Sauce:
Melt the unsalted butter in a medium saucepan over medium heat. Add the minced fresh garlic and sauté for about one minute until fragrant but not browned to avoid bitterness. Whisk in the all-purpose flour and cook for one minute to make a roux which will thicken the sauce. Slowly pour in the milk while whisking constantly to prevent lumps. Add in the chicken broth and keep whisking until the sauce thickens, usually three to four minutes. Stir in the grated Parmesan cheese, Italian seasoning, salt, and pepper. Once smooth and creamy, remove from heat and stir in fresh parsley for a burst of green freshness.
Assemble the Stuffed Shells:
Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a 9 by 13-inch baking dish. Spread a thin layer of the garlic butter sauce evenly across the bottom to keep the shells moist during baking. Use a spoon to fill each cooled pasta shell with the chicken and cheese filling. Arrange the stuffed shells snugly in the dish. Pour the remaining garlic butter sauce all over them. Sprinkle shredded mozzarella and Parmesan on top for a bubbly cheesy crust when baked.
Bake the Dish:
Cover the baking dish with foil and place it in the preheated oven. Bake covered for 20 minutes to allow the flavors to meld and heat through. Remove the foil and bake uncovered for another 10 minutes until the cheese on top is melted and golden brown. Let the baked shells rest for five minutes before serving so the sauce can thicken to a perfect consistency.

My favorite ingredient has to be the fresh garlic in the sauce because it lends such a warm, inviting aroma that fills the kitchen as it cooks. I remember making this for a Sunday dinner and the whole family gathering in the kitchen, drawn by that irresistible garlic smell, made it even more special.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to three days. Reheat gently in the oven or microwave, adding a splash of milk if the sauce has thickened too much. You can freeze the fully assembled shells before baking by wrapping the baking dish tightly with foil and plastic wrap. When ready to bake, thaw overnight in the fridge and then bake as directed, adding a few extra minutes since it’s chilled.

Ingredient Substitutions

Shredded rotisserie chicken works perfectly and saves time. For a vegetarian version, swap chicken for cooked spinach or sautéed mushrooms. If you want a lighter sauce, use milk instead of half-and-half. Fresh herbs like basil can replace parsley or be mixed in for a slightly different flavor profile.

Serving Suggestions

Serve these stuffed shells alongside a crisp green salad dressed with lemon vinaigrette to cut through the richness. Garlic bread or crusty Italian bread is fantastic for soaking up extra sauce. A simple roasted vegetable medley adds color and nutrition to the meal.

Cultural Context

Stuffed pasta dishes like this one have their roots in Italian-American cuisine, inspired by traditional dishes such as manicotti or cannelloni. The combination of cheeses with a buttery garlic sauce shines as a classic comfort food that blends simplicity with indulgence.

Instructions

Step 01

Bring a large pot of salted water to a boil. Add jumbo pasta shells and cook for 9 to 10 minutes, or until al dente. Drain and rinse under cool water. Toss with olive oil to prevent sticking and set aside to cool.

Step 02

In a large bowl, combine ricotta, mozzarella, Parmesan, egg, parsley, garlic powder, onion powder, salt, and black pepper. Stir until smooth. Fold in shredded chicken until evenly mixed. Cover and refrigerate while preparing sauce.

Step 03

Melt butter over medium heat in a saucepan. Add minced garlic and sauté for 1 minute without browning. Whisk in flour and cook for 1 minute. Gradually add milk while whisking, then chicken broth. Continue whisking until sauce thickens, about 3 to 4 minutes. Stir in Parmesan, Italian seasoning, salt, pepper, and parsley. Remove from heat.

Step 04

Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Spread a thin layer of garlic butter sauce on the bottom. Fill each pasta shell with the chicken mixture and arrange shells snugly in the dish. Pour remaining sauce over shells and sprinkle with mozzarella and Parmesan cheese.

Step 05

Cover the baking dish with foil and bake for 20 minutes. Remove foil and bake uncovered for an additional 10 minutes until cheese is melted and golden. Let rest 5 minutes before serving to allow sauce to thicken.

Notes

  1. Use half-and-half in place of whole milk for a richer sauce.
  2. Ensure pasta is cooked al dente to avoid mushiness.
  3. Freshly shredded cheese melts more smoothly than pre-shredded.
