These stuffed shells are jumbo pasta filled with shredded chicken, ricotta, mozzarella, and Parmesan, then baked under a blanket of Alfredo sauce until the cheese on top is just starting to brown. The whole thing comes together in 50 minutes and feeds four people well. It’s the kind of dinner that works on a Tuesday and still looks good enough to bring to a potluck.
The short version of why this works
Two things make this recipe reliable. First, pulling the shells out of the boiling water while they’re still slightly firm — true al dente — matters more here than with regular pasta. They’ll finish cooking in the oven, and if they go in already soft, they turn mushy and tear when you try to stuff them. Second, spreading a full cup of Alfredo sauce on the bottom of the baking dish before you add the shells keeps the pasta from sticking and drying out during the covered bake. That bottom layer essentially steams the shells from underneath while the top sauce melts into the cheese above. Both steps are easy, but skipping either one changes the result.
What can go wrong
- Shells stick together after draining. Toss them with the tablespoon of olive oil right after draining. If you skip this and walk away, they’ll clump and tear when you try to separate them.
- Filling falls out during stuffing. The mixture needs to be thick enough to hold its shape. If your ricotta is watery, drain it in a fine mesh strainer for 15 minutes before mixing. Wet ricotta makes a loose filling that slides out of the shells.
- The top dries out before the cheese browns. This usually means the foil wasn’t sealed tightly enough during the first 25 minutes. Press the foil down around the edges of the dish so steam stays in. Then remove it for the final 5 minutes to get the browning.
- Sauce tastes flat after baking. Jarred Alfredo sauce can lose brightness in the oven. A small squeeze of lemon juice stirred into the sauce before you pour it over the shells fixes this without changing the flavor profile.
- Shells split when stuffed. Use a small spoon or a piping bag. Don’t overfill — about two heaping tablespoons of filling per shell is enough. Forcing too much in is the main reason shells crack.
Shopping notes
- Jumbo pasta shells (conchiglioni): Buy a few more than 12. Some always tear during cooking. Most boxes contain enough to account for breakage, but check before you start.
- Alfredo sauce: If you’re using jarred, look for one with a short ingredient list — cream, butter, Parmesan, garlic. Avoid anything with modified starch as a primary thickener; it tends to separate when baked.
- Rotisserie chicken: A store-bought rotisserie chicken is the most practical source for the shredded chicken here. One breast from a rotisserie bird gives you roughly the right amount and is already seasoned. Skip the garnish — not worth the extra dish to wash just for a pinch of parsley.
Keeping and reheating
Leftovers keep well in an airtight container in the fridge for up to four days, which makes this a strong candidate for cooking a double batch on the weekend. To reheat, place shells in an oven-safe dish, add a splash of water or extra Alfredo sauce to prevent drying, cover tightly with foil, and warm at 325°F (160°C) for about 20 minutes. The microwave works for a single portion — cover loosely and heat in 90-second intervals, adding a small spoon of water if the sauce looks tight. For freezing, assemble the dish fully but don’t bake it; wrap tightly and freeze for up to two months. Bake from frozen at 350°F covered for 45 minutes, then uncover for 10 more.
Chicken Alfredo Stuffed Shells (Creamy & Easy)
Equipment
- Large pot (for boiling shells)
- 13×9 inch (33x23cm) baking dish
- Medium mixing bowl
- Aluminum foil
- Instant-read thermometer (to verify chicken is fully cooked before shredding)
Ingredients
- 6 oz jumbo pasta shells approximately 170g, uncooked
- 1 large chicken breast cooked and shredded, approximately 225g / 8oz
- 2 cups Alfredo sauce 480ml, preferably homemade or a high-quality store-bought brand
- 1 cup ricotta cheese 250g, fresh
- 1 cup mozzarella cheese 115g, shredded
- ½ cup Parmesan cheese 50g, freshly grated
- 1 teaspoon garlic powder
- ½ teaspoon black pepper freshly ground
- 1 tablespoon olive oil
- 1 tablespoon fresh parsley chopped, for garnish
- 1 pinch salt for boiling water
Instructions
- Preheat your oven to 350°F / 175°C (180°C fan-forced). Bring a large pot of salted water to a rolling boil. Cook the jumbo pasta shells until just shy of al dente, about 9-10 minutes (1 minute less than package directions). Drain and toss gently with 1 tablespoon olive oil to prevent sticking. Set aside to cool slightly.6 oz jumbo pasta shells, 1 tablespoon olive oil, 1 pinch salt
- In a medium-sized bowl, combine the shredded chicken, ricotta cheese, mozzarella cheese, Parmesan cheese, garlic powder, and black pepper. Mix until well combined.1 large chicken breast, 1 cup ricotta cheese, 1 cup mozzarella cheese, 1/2 cup Parmesan cheese, 1 teaspoon garlic powder, 1/2 teaspoon black pepper
- Carefully stuff each shell with the chicken mixture, being gentle so as not to break the pasta.6 oz jumbo pasta shells
- In a 13×9 inch (33x23cm) baking dish, spread 1 cup of Alfredo sauce evenly across the bottom. Arrange the stuffed shells seam-side up in a single layer on top of the sauce. Spoon the remaining Alfredo sauce over the shells, making sure each one is coated.2 cups Alfredo sauce
- Cover the baking dish tightly with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 5 minutes until the cheese is lightly golden and the sauce is bubbling around the edges. The internal temperature should reach 165°F / 74°C.
- Remove from the oven and allow the dish to cool slightly. Garnish with freshly chopped parsley before serving.1 tablespoon fresh parsley

Common questions
Can I make this ahead of time?
Yes — you can assemble the entire dish up to 24 hours in advance and refrigerate it unbaked. Pull it out of the fridge 20 minutes before you plan to bake so it’s not ice-cold going into the oven, then add about 5 extra minutes to the covered bake time.
Can I use uncooked chicken instead of pre-cooked?
No, the oven time isn’t long enough to safely cook raw chicken inside a stuffed shell. The chicken needs to be fully cooked and shredded before it goes into the filling — the bake is just to heat everything through and melt the cheese.
What if I can’t find jumbo shells?
Manicotti tubes are the closest substitute and work with the same filling and baking method. You can also use the filling as a baked pasta by layering it lasagna-style with regular pasta sheets if jumbo shells aren’t available.
