This chicken alfredo stuffed shells recipe transforms ordinary pasta into an extraordinary casserole that's guaranteed to become a family favorite. The jumbo shells cradle a decadent mixture of tender chicken, crispy bacon, and cheesy goodness, all bathed in creamy alfredo sauce for the ultimate comfort food experience.
I first made these stuffed shells for a potluck dinner with friends, and they disappeared within minutes. Now they're requested at every gathering, and my family cheers whenever they see me preparing the jumbo shells.
Ingredients
- Jumbo pasta shells: Cooked al dente provides the perfect vessel for holding all the creamy filling
- Alfredo sauce: Creates the rich, velvety base that makes this dish so irresistible
- Shredded chicken breast: Adds hearty protein and works perfectly with the creamy sauce
- Crispy bacon: Brings smoky flavor and delightful texture contrast
- Mozzarella cheese: Melts beautifully for that Instagram-worthy cheese pull
- Parmesan cheese: Adds depth and nutty flavor to both filling and topping
- Ranch dressing mix: Is my secret weapon for exceptional flavor in every bite
- Fresh parsley: Brightens the rich flavors and adds visual appeal
Step-by-Step Instructions
- Prepare the baking dish:
- Preheat oven to 425°F and spray a 9x13 baking dish with nonstick spray. This prevents sticking and makes cleanup much easier.
- Create the filling:
- Whisk together 15 ounces of alfredo sauce, tablespoon of chopped parsley, ranch dressing mix, and black pepper until smooth. The ranch mix is crucial here as it adds incredible flavor complexity that elevates the entire dish.
- Add the proteins and cheese:
- Stir the shredded chicken, half cup of bacon, one and a half cups of mozzarella, and quarter cup of parmesan into the alfredo mixture. Mix thoroughly until every component is evenly distributed for consistent flavor in each bite.
- Fill the shells:
- Spoon about two tablespoons of filling into each cooked jumbo shell, arranging them in the prepared baking dish. This amount gives you the perfect ratio of pasta to filling without overstuffing.
- Add the sauce layer:
- Pour the remaining 22 ounces of alfredo sauce evenly over the filled shells. This creates a luscious bath that keeps the pasta moist while baking and prevents the edges from drying out.
- Top with cheese and bacon:
- Sprinkle the remaining mozzarella, parmesan, and bacon over the sauced shells. This creates that incredible golden, bubbling topping that makes everyone eager to dig in.
- Bake to perfection:
- Cover with foil and bake for 20 minutes, then uncover and broil for 3-4 minutes until golden. Watching carefully during broiling prevents burning while achieving that perfectly browned cheese top.

The combination of ranch seasoning with alfredo sauce creates a flavor profile that's simply magical. I discovered this pairing by accident when I ran out of Italian seasoning, and now I wouldn't make it any other way. My teenage son, who typically avoids anything creamy, requests this dish at least twice a month.
Make-Ahead Options
These stuffed shells work beautifully as a make-ahead meal. Prepare everything up to the baking step, cover tightly with foil, and refrigerate for up to 24 hours. When ready to serve, add an extra 10-15 minutes to the baking time if cooking from cold. The flavors actually develop more deeply when prepared in advance.
Storage and Reheating
Leftover stuffed shells will keep in an airtight container in the refrigerator for up to 4 days. For best results when reheating, add a splash of milk or cream to prevent the sauce from becoming too thick. Cover with foil and warm in a 350°F oven until heated through, about 20 minutes. The microwave works in a pinch but may make the pasta slightly chewy.
Ingredient Substitutions
These stuffed shells are incredibly versatile. Rotisserie chicken works beautifully as a time-saver. Turkey bacon creates a lighter version without sacrificing flavor. For a vegetarian option, replace the chicken with sautéed mushrooms and spinach. Dairy free alternatives for the alfredo sauce and cheeses can work, though the texture will differ slightly from the original.
Serving Suggestions
Serve these stuffed shells with a crisp green salad dressed with vinaigrette to balance the richness. Garlic bread makes an excellent accompaniment for soaking up extra sauce. For a complete meal, roasted vegetables like broccoli or asparagus provide nutritional balance and color contrast on the plate.
