Ingredients

Here’s what you’ll need to gather from your pantry and fridge to make this magic happen. Most of these are kitchen staples, but together they create something truly special!

  • 20 jumbo pasta shells: Look for the ones specifically labeled “jumbo.” We need big boys to hold all that yummy filling!
  • 2 cups cooked, shredded chicken: This is a perfect way to use up leftover rotisserie chicken or chicken breasts you cooked earlier in the week. Easy peasy!
  • 1 cup buffalo sauce: Use your favorite brand! The kind you’d use for wings is perfect. This brings the signature tang and heat.
  • 1 (8 ounce) block cream cheese, softened: Make sure it’s nice and soft so it mixes smoothly into the filling. Leave it out on the counter for an hour or two, or microwave it gently for 15-20 seconds.
  • 1/2 cup blue cheese crumbles (optional): If you love that classic buffalo-blue combo, definitely add these in! If not, no worries, the filling is still amazing without it.
  • 1/2 cup milk: Just a splash to help bring the filling together.
  • 1/4 cup unsalted butter: The start of our glorious Alfredo sauce.
  • 2 cloves garlic, minced: Garlic is a must! Mince it fresh for the best flavor.
  • 1/4 cup all-purpose flour: This helps thicken our Alfredo sauce.
  • 2 cups milk: This forms the base of our creamy sauce. Whole milk works best for richness, but 2% is fine too.
  • 1 cup grated Parmesan cheese: Freshly grated is ALWAYS better if you can swing it! It melts smoother and has a stronger flavor than pre-shredded.
  • 1/2 teaspoon black pepper: A little spice boost for the sauce.
  • Optional garnish: fresh chopped parsley or green onions: A sprinkle of green at the end makes it look pretty and adds a little freshness.

How to Make It

Okay, let’s get cooking! Follow these steps and you’ll have a bubbly, cheesy masterpiece ready in no time.

  1. Preheat your oven to 375°F (190°C). Get that oven nice and hot while you prep everything.
  2. Grab a big pot and cook those jumbo shells according to the package directions. You want them al dente, which means they should still have a slight bite to them. They’ll cook more in the oven, so don’t overdo it here! Drain them thoroughly in a colander and let them cool down just enough so you can handle them without burning your fingers.
  3. While the shells are cooling, let’s make that amazing filling! In a large bowl, toss together your shredded cooked chicken, 1 cup of buffalo sauce, the softened cream cheese, and those blue cheese crumbles if you’re using them. Now, get in there and mix it all up. I like to use a spoon or a spatula, but sometimes getting your hands in there (with clean hands, of course!) is the easiest way to ensure everything is evenly combined and the cream cheese is totally incorporated.
  4. Now for the fun part (and maybe a little messy part!): filling the shells! Take each cooled shell and generously stuff it with the buffalo chicken mixture. Don’t be shy, really fill ’em up! Arrange the filled shells in a single layer in a greased 9×13 inch baking dish. They should fit snugly.
  5. Time to make the creamy Alfredo sauce! Get a medium saucepan and melt the butter over medium heat. Once the butter is melted and maybe just starting to foam a little, add the minced garlic. Cook for just about 1 minute, stirring constantly, until you can smell that wonderful garlic aroma. Don’t let it brown!
  6. Now, whisk in the flour with the melted butter and garlic. Keep whisking constantly for 1-2 minutes. This step is called making a roux, and it helps thicken your sauce and cooks out the raw flour taste. You’ll have a smooth, paste-like mixture.
  7. Slowly, gradually, whisk in the 2 cups of milk. Pour a little, whisk until smooth, pour a little more, whisk again. This helps prevent lumps! Keep whisking and cooking over medium heat. The sauce will start to thicken after about 5-7 minutes. You want it thick enough to coat the back of a spoon, but still pourable.
  8. Take the saucepan off the heat. Now, stir in the grated Parmesan cheese and the black pepper. Stir until the cheese is completely melted and the sauce is silky smooth. Taste it! Does it need a pinch more pepper? Maybe a tiny bit of salt, although the Parmesan and buffalo sauce are pretty salty.
  9. Pour that beautiful, creamy Alfredo sauce evenly all over the stuffed shells in the baking dish. Make sure they’re all nicely coated!
  10. Pop the dish into your preheated oven. Bake for 20-25 minutes, or until the sauce is bubbly around the edges and the tops of the shells look lightly golden brown. This is when your kitchen will start smelling absolutely incredible!
  11. Once it’s out of the oven, let it rest for a few minutes before serving. This helps the sauce set up a little and keeps you from burning your tongue! If you like, sprinkle with fresh chopped parsley or green onions for a pop of color and freshness.

Serve it up hot and get ready for rave reviews!

Substitutions & Additions

Want to play around with this recipe? Great! Here are a few ideas:

  • Chicken: No cooked chicken? Boil or bake chicken breasts just for this recipe, or even use leftover turkey!
  • Cheese: Not a blue cheese fan? You can omit it entirely, or use ricotta cheese mixed into the chicken filling for extra creaminess. A sprinkle of mozzarella on top of the Alfredo before baking would also be delicious!
  • Spice Level: Use more or less buffalo sauce depending on how spicy you like it. You could also add a pinch of cayenne pepper to the filling for extra heat.
  • Veggies: Want to sneak in some greens? Finely chopped spinach or even some finely diced celery (like in traditional buffalo chicken dip!) could be added to the chicken filling.
  • Pasta: While jumbo shells are classic for stuffing, you could probably adapt this to a baked ziti or penne dish by chopping the chicken filling and mixing everything together before baking, though the texture would be different.

Tips for Success

A few little things to keep in mind to make sure your Buffalo Chicken Alfredo Shells turn out perfect every time!

  • Don’t overcook the pasta! Al dente is your friend here. Since the shells bake again, if they’re mushy going in, they’ll be even mushier coming out.
  • Soften that cream cheese! This is key for a smooth filling. Hard cream cheese will leave you with annoying little lumps.
  • Whisk the roux well. Cooking the flour for a minute or two helps get rid of that raw flour taste in your Alfredo sauce.
  • Add milk gradually to the roux. Pouring it all in at once is the fastest way to a lumpy sauce. Take your time and whisk constantly as you add it bit by bit.
  • Melt Parmesan off heat. Adding cheese to a bubbling hot sauce can make it seize up or become oily. Removing the pan from the heat before stirring in the cheese helps it melt smoothly and evenly.
  • Let it rest. Just a few minutes makes a difference in the sauce’s consistency when serving.
  • Prep Ahead: You can make the chicken filling and the Alfredo sauce separately a day in advance. Store them covered in the fridge. When you’re ready to bake, stuff the shells, assemble the dish, pour the sauce over, and bake as directed, maybe adding 5-10 minutes to the baking time since it’s starting cold.

How to Store It

Got leftovers? Lucky you! This dish is actually really good reheated.

  • Let the casserole cool completely.
  • Cover the baking dish tightly with plastic wrap, then foil, or transfer individual portions to airtight containers.
  • Store in the refrigerator for up to 3-4 days.
  • To reheat, you can microwave individual portions, or cover the baking dish with foil and reheat in a 350°F (175°C) oven until heated through (this might take 20-30 minutes). You might want to add a splash of milk before reheating if the sauce seems a little dry.
  • Freezing: You can freeze this, but sometimes creamy sauces can change texture slightly when frozen and reheated. If you want to freeze, I recommend assembling the dish (stuffed shells + sauce) in a freezer-safe dish without baking it. Cover tightly and freeze for up to 2-3 months. When ready to eat, thaw overnight in the fridge and then bake as directed, adding extra time as needed until bubbly and heated through.

FAQs

Got questions? I’ve got answers!

Can I use rotisserie chicken?

Absolutely! Rotisserie chicken is perfect for this recipe. Just shred it up and you’re good to go.

Is this dish very spicy?

The spice level depends on the buffalo sauce you use. Most standard buffalo sauces offer a mild to medium heat. If you’re sensitive to spice, use a milder sauce or reduce the amount slightly in the filling.

Can I make the filling ahead of time?

Yes! You can make the buffalo chicken filling up to 2 days in advance and keep it covered in the refrigerator until you’re ready to stuff the shells and assemble the casserole.

My Alfredo sauce is lumpy! What did I do wrong?

Usually, a lumpy sauce happens if you didn’t whisk the flour and butter (the roux) long enough, or if you added the milk too quickly and didn’t whisk continuously. Don’t despair! You can try passing the sauce through a fine-mesh sieve before pouring it over the shells, or use an immersion blender to smooth it out right in the pan.

Notes

Don't overcook the pasta; al dente is best as it will cook further in the oven. Ensure the cream cheese is softened for a smooth filling. Whisk the roux (flour and butter) well to cook out the raw flour taste and add milk gradually to prevent lumps. Melt the Parmesan off heat for a smoother sauce. Let the dish rest briefly before serving. You can make the filling and sauce ahead (up to 2 days) and store in the fridge. To store leftovers, cool completely, cover tightly, and refrigerate for 3-4 days. Reheat individual portions in the microwave or cover the dish and reheat in a 350°F (175°C) oven. You can also assemble (but not bake) the dish and freeze for 2-3 months; thaw in the fridge before baking.
