Prep notes
Have all ingredients measured and ready before you begin. The chicken should be cut into bite-sized cubes so it cooks quickly and mixes easily with the cheese filling. Preheat your oven while you cook the pasta so the assembled shells go straight into a hot oven and bake evenly.
Step-by-step instructions
- Preheat and prepare: Preheat your oven to 375°F (190°C). Lightly oil a 9×13-inch baking dish or similar oven-safe dish and set it aside.
- Boil the jumbo shells: Bring a large pot of salted water to a boil. Add the 12 ounces of dry jumbo pasta shells and cook them according to package directions until al dente — usually a minute or two less than fully tender so they hold their shape while you assemble. Drain the shells and spread them out on a baking sheet or a clean kitchen towel so they don’t stick together.
- Cook the chicken: While the pasta cooks, heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the 1 pound of cubed boneless, skinless chicken breasts in a single layer. Let the chicken brown on one side for 2–3 minutes without moving it, then stir and continue to cook until the cubes are cooked through and no longer pink in the center, about 6–8 minutes total depending on size. Remove the skillet from the heat and allow the chicken to cool slightly.
- Combine the filling: In a medium mixing bowl, add 15 ounces ricotta cheese, the cooked cubed chicken, 5 ounces shredded Parmesan cheese (reserve about 1 ounce for sprinkling on top later), and 1 tablespoon Italian seasoning. Stir everything gently until the mixture is evenly combined. Taste the filling and add a pinch of salt and pepper if you like; keep in mind the Parmesan adds saltiness already.
- Fill the shells: Spoon about 1–2 tablespoons of the ricotta-and-chicken mixture into each cooked jumbo shell. Place each filled shell in the prepared baking dish with the opening facing up. Arrange the shells in a single layer so they fit snugly but not stacked.
- Add the sauce: Pour the 24 ounces of marinara sauce evenly over and around the filled shells. Use the back of a spoon to spread sauce into any gaps; you want the bottom of the shells covered so they stay moist while baking.
- Top and finish: Sprinkle the reserved shredded Parmesan cheese over the sauce and shells. If you like a little extra ooze, add a light drizzle of olive oil over the top.
- Bake: Transfer the baking dish to the preheated oven and bake at 375°F (190°C) until the sauce is bubbling and the cheese is melted and lightly golden, about 20–25 minutes.
- Rest and serve: Remove the dish from the oven and let it rest for 5 minutes so the filling firms slightly. Serve the shells hot with a simple green salad or garlic bread for a complete meal.
Tips for success
- Do not overcook the jumbo shells in the boiling water. Slightly undercooked shells are easier to stuff and finish perfectly in the oven.
- Cut the chicken into uniform cubes so it cooks evenly. If pieces are too large, they’ll take much longer to cook.
- If you prefer a smoother filling, pulse the cooked chicken a few times in a food processor before folding it into the ricotta. Be careful not to purée it — you still want some texture.
- Leftovers: Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. Reheat covered in a 350°F (175°C) oven until warmed through, about 15–20 minutes.
Variations and add-ins
- Spinach: Fold 6–8 ounces of wilted and squeezed-dry spinach into the ricotta filling for a boost of color and nutrients.
- Herbs: Fresh basil or parsley stirred into the filling brightens the dish. Add about 2 tablespoons chopped fresh herbs.
- Cheese swap: Swap part of the ricotta for cottage cheese if you prefer a lighter texture, using the same total volume.
- Heat: Add red pepper flakes to the marinara or the filling if you like some heat.
What to serve with Chicken Stuffed Shells
A crisp green salad with a tangy vinaigrette cuts through the richness of the cheese. Garlic bread or a warm baguette is perfect for mopping up sauce. For vegetables, roasted broccoli or a simple sautéed green bean with lemon makes a bright, easy side.
Make-ahead and freezer notes
To assemble ahead: Prepare the stuffed shells through step 5, cover the baking dish tightly, and refrigerate for up to 24 hours. When ready to bake, remove from the fridge while the oven heats and bake covered with foil for 25–30 minutes, then uncover to let the cheese brown for 5–10 minutes.
To freeze: Assemble the shells in a freezer-safe baking dish, cover tightly with plastic wrap and foil, and freeze for up to 2 months. Bake from frozen at 375°F (190°C) for about 45–55 minutes covered, then uncover and bake until bubbling and the cheese is golden, about 10–15 more minutes.
Notes on ingredients
I used a simple jarred marinara for ease, but feel free to swap in your favorite store-bought brand or homemade sauce. The Italian seasoning adds an herby backbone; use a mix of oregano, basil, thyme, and rosemary if you prefer to sprinkle in individual dried herbs. The Parmesan is grated so it melts into the filling and blankets the shells with a savory finish.
Final thoughts
These Chicken Stuffed Shells are reliable, comforting, and versatile. They bring together pantry staples and a little fresh cooking to deliver a family-pleasing meal. The method is straightforward: cook pasta, brown chicken, mix with ricotta and Parmesan, stuff shells, top with marinara, and bake. Follow the steps above and you’ll have a satisfying dinner with minimal fuss and maximum flavor.
Happy cooking — and enjoy every cheesy, saucy bite.

Ingredients
Equipment
Method
- Preheat the oven to 400°F (200°C).
- Heat 1 tablespoon olive oil in a large skillet over medium heat.
- Add the cubed chicken and cook, stirring occasionally, until browned and cooked through, about 5 minutes; transfer to a plate with a slotted spoon.
- Bring a large pot with 4 cups (or enough) of water to a boil. Add the jumbo shells and cook until al dente, about 10 minutes. Drain thoroughly in a colander and let cool slightly so shells do not tear.
- In a mixing bowl, combine the cooked chicken, 15 ounces ricotta, three-quarters of the shredded Parmesan (reserve remaining for topping), and 1 tablespoon Italian seasoning. Stir until evenly mixed.
- Spoon a thin layer of marinara sauce into the bottom of a 9×13 baking pan.
- Fill each cooked shell with the chicken-ricotta mixture and place filled shells in the prepared baking dish in a single layer.
- Pour the remaining marinara sauce evenly over the filled shells and sprinkle the remaining Parmesan cheese on top.
- Bake in the preheated oven for 20 minutes until heated through and cheese is melted. Remove and serve.
Notes
- Drain shells thoroughly and separate them to prevent sticking.
- Reserve some Parmesan to sprinkle on top before baking.
- Let cooked shells cool slightly so they are easier to fill.
- Use a slotted spoon to remove chicken so excess oil drains away.
