Chicken Alfredo Stuffed Shells

The smell of garlic butter hitting a hot pan always pulls me straight back to Wednesday nights when I needed something that felt indulgent but didn't require a culinary degree. I'd started making these stuffed shells after a friend brought a similar dish to a potluck, and I couldn't stop thinking about how the creamy filling tucked inside each shell made every bite feel like a little present. The first batch I made, I overstuffed them and they split open in the oven, but even then, scraped onto plates with extra sauce, they disappeared in minutes. There's something about pasta shells that makes people lean in closer at the dinner table. This dish became my answer to those evenings when I wanted comfort without compromise.

I made this for my neighbor after she had surgery, and when she returned the empty dish three days later, she asked if I'd written down the recipe because her kids had been asking for it every night since. That's when I realized this wasn't just another pasta bake. It had that rare quality of being both cozy and celebratory, the kind of food that works for a quiet Tuesday or a birthday dinner. I've since made it for book club, for my sister's baby shower, and for myself on a rainy Sunday when I needed something to look forward to. It never fails to make people reach for seconds.

Ingredients

• Jumbo pasta shells: These are the heroes that hold everything together, and cooking them just until al dente means they won't turn mushy during baking.
• Cooked chicken breast: Rotisserie chicken is my secret shortcut here, already seasoned and ready to shred, saving you at least twenty minutes of prep time.
• Whole milk ricotta cheese: The creamy base of the filling that keeps everything moist and rich without being heavy, and whole milk makes all the difference in texture.
• Shredded mozzarella cheese: This melts into stretchy, golden perfection both inside the shells and on top, creating those irresistible cheese pulls.
• Grated Parmesan cheese: Sharp and salty, it amplifies the savory depth in both the filling and the Alfredo sauce.
• Fresh parsley: A handful of this brightens the whole dish and cuts through the richness with a whisper of freshness.
• Large egg: It binds the filling together so it stays put inside each shell instead of oozing out during baking.
• Garlic powder: A gentle background note that seasons the filling without overpowering the delicate cheese blend.
• Unsalted butter: The foundation of a proper Alfredo sauce, giving it that silky, luxurious texture.
• Fresh garlic cloves: Sautéed until fragrant, they infuse the sauce with a warmth that garlic powder just can't match.
• Heavy cream: This is what makes Alfredo sauce truly Alfredo, thick and velvety and coating every surface it touches.
• Nutmeg: Just a pinch adds a mysterious warmth that people notice but can't quite name.

Instructions

Prep your oven and dish:

Set your oven to 375°F and give your baking dish a light coating of butter or cooking spray so nothing sticks. This step matters more than you'd think when cheese is involved.

Cook the shells:

Boil the jumbo shells in well salted water until they're just al dente, then drain and let them cool enough to handle. I like to spread them out on a baking sheet so they don't stick together while I make the filling.

Mix the chicken filling:

In a big bowl, combine the shredded chicken, ricotta, mozzarella, Parmesan, parsley, egg, garlic powder, salt, and pepper until everything is evenly distributed. The mixture should be thick and scoopable, not runny.

Make the Alfredo sauce:

Melt butter in a saucepan over medium heat, add the minced garlic, and let it sizzle for about a minute until your kitchen smells amazing. Pour in the heavy cream, bring it to a gentle simmer, then whisk in the Parmesan until the sauce thickens and coats the back of a spoon, seasoning with nutmeg, salt, and pepper.

Prepare the baking dish:

Spread half a cup of that Alfredo sauce across the bottom of your baking dish to create a creamy bed for the shells. This prevents sticking and adds extra sauce to every bite.

Stuff the shells:

Spoon about two tablespoons of the chicken mixture into each shell and nestle them into the dish seam side up. Don't worry if they're not perfect, rustic is part of the charm here.

Add sauce and cheese:

Pour the remaining Alfredo sauce over the filled shells, making sure to get into the corners, then sprinkle the mozzarella and Parmesan on top. The cheese will turn golden and bubbly as it bakes.

Bake covered, then uncovered:

Cover the dish with foil and bake for twenty minutes, then remove the foil and bake another ten minutes until the top is golden and the sauce is bubbling at the edges. Letting it rest for five minutes before serving helps everything set up just right.

The first time I brought these to a family gathering, my aunt pulled me aside and asked if I'd been taking cooking classes because she couldn't believe I'd made something so restaurant worthy. I hadn't, but that comment made me realize that certain dishes have the power to change how people see you in the kitchen. Now, whenever someone asks me to bring something to dinner, this is what I make, and I always get requests for the recipe before dessert is even served. It's become my signature dish without me ever planning for it to be.

Choosing Your Chicken

Rotisserie chicken is my go to because it's already seasoned and juicy, and you can shred it in minutes while the pasta boils. If you're cooking chicken from scratch, poaching it in chicken broth with a bay leaf and some peppercorns keeps it tender and adds subtle flavor. I've also used leftover grilled chicken or even turkey during the holidays, and both work beautifully. The key is making sure the meat is moist, not dry, because it needs to blend seamlessly with the creamy ricotta. Whatever you choose, shred or dice it into bite sized pieces so every shell has an even distribution of chicken in each forkful.

Making Ahead and Freezing

This dish is a dream for meal prep because you can assemble it completely, cover it tightly, and refrigerate it for up to twenty four hours before baking. I've also frozen unbaked shells with great success by wrapping the dish in two layers of plastic wrap and then foil, and they'll keep for up to two months. When you're ready to bake from frozen, add an extra fifteen minutes of covered baking time and check that the center is hot all the way through. The sauce might look a little separated when it first comes out, but a gentle stir once it's baked brings it right back together. Leftovers reheat in the microwave or oven, and I often add a splash of milk or cream to keep them from drying out.

Serving Suggestions and Variations

I almost always serve these shells with a simple arugula salad dressed in lemon and olive oil because the peppery greens cut through the richness perfectly. Garlic bread or a warm baguette is essential for soaking up every bit of that Alfredo sauce left on the plate. If you want to sneak in some vegetables, sautéed spinach or finely chopped mushrooms mixed into the filling add nutrition without changing the flavor profile. You could also swap the chicken for cooked shrimp or even keep it vegetarian by using just cheese and spinach. I've made a version with sun dried tomatoes and fresh basil that tasted like summer, and another with crumbled bacon that disappeared even faster than usual.

• Try adding a pinch of red pepper flakes to the Alfredo sauce if you like a little heat
• Swap half the mozzarella for fontina or Gruyère for a more complex, nutty flavor
• Garnish with extra fresh parsley or even torn basil right before serving for a pop of color and freshness

Save to Pinterest

Every time I pull this dish out of the oven and see the cheese bubbling and golden, I remember why I keep coming back to it even after trying dozens of other pasta bakes. It's the kind of recipe that makes you feel like a better cook than you actually are, and it never disappoints the people you share it with.

Recipe FAQs

→ Can I use regular pasta shells instead of jumbo shells?

Yes, regular shells work, but you'll need to reduce the filling amount per shell and may need to increase the total quantity. Jumbo shells hold more filling and create a more impressive presentation.

→ How do I prevent the shells from breaking while cooking?

Cook the shells to al dente (slightly firm) rather than fully soft. Let them cool slightly before filling, and handle them gently. The pasta will finish cooking in the oven.

→ Can I make this dish ahead and refrigerate it?

Absolutely. Assemble the dish, cover it with foil, and refrigerate for up to 24 hours. Add 10-15 minutes to baking time if baking from cold.

→ What's the best way to reheat leftovers?

Cover with foil and reheat in a 350°F oven for 15-20 minutes until warmed through. Alternatively, microwave individual portions in a covered dish for 2-3 minutes, stirring halfway.

→ How can I make this vegetarian?

Replace the shredded chicken with sautéed mushrooms, spinach, or a combination of vegetables. You can also use crumbled tofu for added protein while maintaining the creamy texture.

→ Can I freeze this dish for later?

Yes, freeze unbaked for up to 3 months. Thaw overnight in the refrigerator, then bake as directed, adding extra time as needed.
