12 oz (approx. 24–28 pieces) Jumbo Pasta Shells
2 tbsp Olive Oil (divided)
1 lb (450g) Boneless, Skinless Chicken Breasts or Thighs, finely diced or shredded
1 tsp Italian Seasoning
1/2 tsp Smoked Paprika
1/2 tsp Garlic Powder
1/2 tsp Onion Powder
1 tsp Salt (plus extra for pasta water)
1/2 tsp Freshly Cracked Black Pepper
1 cup Ricotta Cheese (full-fat or part-skim)
1 cup Shredded Mozzarella Cheese (divided)
1/2 cup Freshly Grated Parmesan Cheese
1 large Egg (beaten, to bind the filling)
2 tbsp Fresh Parsley, finely chopped

Bring a large pot of heavily salted water to a rolling boil over High Heat.
Add the jumbo shells and cook according to package instructions, but stop 2 minutes short of full cooking time (usually about 9–10 minutes). The shells should remain firm (al dente) so they hold their shape during stuffing and baking.
Drain carefully and rinse under cool water to stop the cooking process. Coat lightly with a drizzle of olive oil to keep them from sticking together. Set aside.

Heat 1 tablespoon of olive oil in a skillet over Medium-High Heat.
Add the finely diced chicken breasts. Season with Italian seasoning, smoked paprika, garlic powder, onion powder, salt, and black pepper.
Sear for 5–7 minutes, stirring occasionally, until cooked through and golden on the outside. Remove from heat and let cool slightly.

In a large mixing bowl, combine the cooked diced chicken, ricotta cheese, 1/2 cup of shredded mozzarella cheese, 1/2 cup of grated Parmesan cheese, beaten egg, and chopped fresh parsley.
Mix thoroughly until well combined. Taste and adjust seasoning with a pinch of salt or pepper if needed.

In a saucepan or skillet, melt the unsalted butter over Medium-Low Heat.
Add the minced garlic and sauté for 1–2 minutes until fragrant. Avoid browning the garlic to prevent bitterness.
Whisk in the flour and cook for 1 minute to remove the raw flour taste.
Slowly pour in the chicken broth while whisking continuously to prevent lumps. Follow with the heavy whipping cream.
Bring the mixture to a soft simmer over Medium Heat, then reduce to Low Heat and let it simmer gently for 3–4 minutes until it thickens slightly.
Stir in 1 cup of freshly grated Parmesan cheese and red pepper flakes. Stir until the cheese is completely melted and the sauce is smooth. Remove from heat.

Preheat your oven to 375°F (190°C).
Pour about 1 cup of the garlic Parmesan sauce onto the bottom of a 9×13-inch baking dish, spreading it into an even layer.
Spoon a generous portion (about 1.5 to 2 tablespoons) of the chicken filling into each cooked pasta shell.
Arrange the filled shells snugly in the baking dish in a single layer.
Pour the remaining garlic Parmesan sauce over the tops of the stuffed shells.
Sprinkle the remaining 1/2 cup of mozzarella cheese over the top.

Cover the baking dish loosely with aluminum foil (tuck it so it doesn’t stick to the melted cheese).
Bake at 375°F (190°C) for 15 minutes.
Remove the foil and bake uncovered for an additional 8–10 minutes, or until the sauce is bubbly and the top cheese is melted, light brown, and slightly crispy around the edges.
Garnish with extra chopped fresh parsley and grated Parmesan before serving. Allow to rest for 5 minutes prior to serving.

Grate Your Own Cheese: Pre-shredded packaged cheeses contain anti-caking agents that prevent a completely smooth melt. Grating your Parmesan block fresh ensures a silky sauce texture.
Don’t Overcook Pasta: Cook shells until barely pliable. Overcooked shells break easily during filling and become mushy after baking.
Add Vegetables: Feel free to fold cooked spinach, sautéed mushrooms, or sun-dried tomatoes into the chicken filling for added color and flavor.
