Garlic Butter Chicken Alfredo Shells
There are some dishes that just feel like a warm hug in a bowl, and for me, this is one of them. We’re taking the familiar, comforting flavours of a classic Chicken Alfredo and giving it a delightful new form. Imagine large pasta shells, cooked until perfectly al dente, each one cradling a rich, creamy filling of shredded chicken, Parmesan, and herbs. These are then nestled in a baking dish, generously drizzled with a fragrant garlic butter sauce, and baked until the cheese is gloriously melty and the top is golden and bubbling. This is my go-to recipe when I need something that feels a bit special but doesn’t require hours chained to the hob.
What I believe makes these Garlic Butter Chicken Alfredo Shells truly stand out is the combination of textures and layered flavours. You get the soft, yielding pasta shell, the substantial and savoury chicken filling, and that luscious, velvety garlic butter sauce that seeps into every nook and cranny. It’s a far more interesting way to enjoy these ingredients than simply tossing them with spaghetti. It transforms a midweek meal into something memorable.
This recipe is ideal for those evenings when you’re craving substantial, satisfying food. It’s a brilliant dish to serve the family, but it’s also impressive enough to present to guests. The individual shells make for a beautiful presentation, and everyone seems to love digging into their own little pockets of cheesy, creamy goodness. It’s the kind of meal that silences a table, in the best possible way.
Recipe Overview
This recipe brings together tender shredded chicken and a creamy Parmesan-Alfredo style filling, all stuffed into large pasta shells. The dish is then baked with a simple yet decadent garlic butter sauce until bubbly and golden. From my experience, using a piping bag (or even a sandwich bag with the corner snipped off) makes filling the shells much cleaner and faster than using a teaspoon.

Ingredients You’ll Need
For the best results, I always recommend grating your own Parmesan. The pre-grated kind often contains anti-caking agents that can prevent the sauce from becoming truly smooth. A block of genuine Parmigiano Reggiano will make a world of difference here.
- 300g large pasta shells (conchiglioni)
- 300g cooked chicken breast, shredded (from about 2 medium breasts)
- 250g full-fat cream cheese, softened
- 100g Parmesan cheese, freshly grated, plus extra for topping
- 60g mozzarella cheese, grated
- 2 tablespoons fresh parsley, finely chopped
- 1 teaspoon dried oregano
- Salt and freshly ground black pepper, to taste
- For the Garlic Butter Sauce:
- 100g unsalted butter
- 4-5 cloves garlic, minced
- 300ml double cream
- 60ml chicken stock
- A pinch of nutmeg
Adam’s Tip: Don’t be shy with the garlic! I’ve specified 4-5 cloves, but if you’re a true garlic enthusiast like me, feel free to add another one. Roasting the garlic first can also add a wonderful, mellow sweetness to the sauce.
How to Make Garlic Butter Chicken Alfredo Shells
The process is straightforward. We’ll cook the pasta, mix the filling, stuff the shells, and then create a simple, luxurious sauce to bake them in. It all comes together in one baking dish for a fuss-free finish.
- Preheat and Prep: Preheat your oven to 180°C (160°C fan). Lightly grease a 23x33cm (9×13 inch) baking dish.
- Cook the Pasta Shells: Bring a large pot of salted water to a boil. Add the pasta shells and cook according to package directions, but for 2 minutes less than the minimum time so they are slightly undercooked (al dente). This prevents them from becoming mushy in the oven. Drain carefully and rinse with cold water to stop the cooking process.
- Make the Chicken Alfredo Filling: In a large bowl, combine the shredded chicken, softened cream cheese, 100g of grated Parmesan, the grated mozzarella, chopped parsley, and dried oregano. Season well with salt and black pepper. Mix until everything is thoroughly combined.
- Stuff the Shells: Carefully spoon the chicken mixture into each cooked pasta shell. I find that using a piping bag or a simple zip-top bag with the corner snipped off makes this step much quicker and less messy. Arrange the stuffed shells snugly in your prepared baking dish.
- Create the Garlic Butter Sauce: In a medium saucepan, melt the unsalted butter over a medium heat. Add the minced garlic and cook for about 1-2 minutes until fragrant, being careful not to let it brown.
- Finish the Sauce: Pour in the double cream and chicken stock. Whisk to combine and bring to a gentle simmer. Let it bubble gently for 3-4 minutes, stirring occasionally, until it has thickened slightly. Season with a pinch of nutmeg, salt, and pepper. For a truly velvety sauce, it’s important not to let it boil rapidly, as explained in this guide to making stable cream sauces.
- Assemble and Bake: Pour the finished garlic butter sauce evenly over the stuffed shells in the baking dish. Sprinkle with a little extra grated Parmesan.
- Bake to Perfection: Place the dish in the preheated oven and bake for 20-25 minutes, or until the sauce is bubbling and the cheese on top is melted and lightly golden. Let it rest for 5 minutes before serving to allow the sauce to settle.
Tips From My Kitchen
- Temperature Control: When making the cream sauce, keep the heat on a medium-low setting. If the cream gets too hot too quickly, it can split or curdle. A gentle simmer is all you need for it to thicken perfectly.
- The Secret Step: Always reserve a cup of the pasta cooking water before you drain the shells. If your Alfredo filling feels a little stiff, adding a tablespoon or two of this starchy water will help loosen it to the perfect consistency without diluting the flavour.
- Make-Ahead: You can fully assemble the dish up to 24 hours in advance. Prepare everything up to the end of step 7, cover the dish tightly with foil, and refrigerate. When ready to bake, you may need to add an extra 10-15 minutes to the cooking time.
- Storage: Leftovers keep brilliantly. Store them in an airtight container in the fridge for up to 3 days. Reheat in the microwave or in the oven at 160°C until heated through, adding a splash of milk or cream if the sauce seems too thick.
What to Serve With Garlic Butter Chicken Alfredo Shells
This dish is wonderfully rich, so I like to pair it with something fresh and simple to cut through the creaminess. Here are a few of my favourite accompaniments:
- A Crisp Green Salad: A simple Classic House Salad with Red Wine Vinaigrette provides a perfect, sharp contrast to the rich, cheesy pasta.
- Garlic Bread: You can never have too much garlic! Some warm, crusty garlic bread is essential for mopping up every last bit of that incredible sauce.
- Wine Pairing: A crisp, dry white wine like a Pinot Grigio or a Sauvignon Blanc works beautifully here. Its acidity helps balance the richness of the Alfredo sauce.
