How to Make Chicken Broccoli Garlic Alfredo Shells (Step-by-Step)
Follow these simple steps to create a delightful meal that everyone will love:
Step 1: Cook the Pasta
Start by boiling a large pot of salted water. Add the jumbo pasta shells and cook them according to the package directions until they're al dente. Be sure to keep an eye on them to avoid overcooking! Drain and set aside while you work on the filling.
Step 2: Cook the Chicken and Broccoli
In a large skillet, heat the olive oil over medium heat. Add the diced chicken, seasoning it with salt, pepper, and Italian seasoning. Sauté the chicken until golden brown, which should take about 6-8 minutes. Once cooked, add the broccoli florets and minced garlic, stirring for an additional 3-4 minutes until the broccoli is bright green and tender.
Step 3: Make the Alfredo Sauce
Pour in the heavy cream while stirring continuously and add the grated Parmesan cheese. Watch as the cheese melts into the cream, creating a luscious sauce! Stir until smooth and glossy, filling your kitchen with the delightful aroma of garlic.
Step 4: Combine and Fill
Preheat your oven to 350°F (175°C). Gently mix the cooked shells into the Alfredo sauce, ensuring each shell is generously coated. Carefully fill each shell with the creamy mixture using a spoon or a small cookie scoop for ease.
Step 5: Top with Cheese
Place the filled shells into a greased 9x13-inch baking dish. Sprinkle shredded mozzarella cheese on top for a deliciously golden crust when baked. The sight of this just before going into the oven is hard to resist!
Step 6: Bake
Bake in the preheated oven for about 25-30 minutes, until the cheese is bubbly and slightly browned. Your kitchen will fill with the heavenly aroma, surely enticing neighbors to take a peek!

Common Mistakes to Avoid
- Overcooking the pasta: Make sure to cook the shells al dente; they will continue to cook in the oven.
- Not seasoning well: Don't forget to season each component, from the chicken to the sauce, or you risk a bland dish.
- Filling shells too loosely: Ensure you fill each shell generously; otherwise, they'll dry out while baking.
Tips and Tricks for Success
- Experiment with different vegetables, like spinach or peas, if you want to switch things up!
- Make it ahead of time: Prep everything and assemble it in the baking dish, then cover and refrigerate until you're ready to bake.
- Consider adding crushed red pepper flakes for a kick of heat.
Variations
- Substitute chicken with turkey or cooked sausage.
- Use gluten-free pasta shells for a gluten-free option.
- Swap out broccoli for zucchini or asparagus.
- Replace heavy cream with a lighter option like half-and-half.
How to Serve
- Pair with a side salad for a refreshing contrast.
- Serve with warm, crusty bread for dipping.
- Add roasted veggies for a splash of color and nutrition.
- Garnish with freshly chopped parsley for an extra touch.

Make Ahead and Storage
- Make Ahead: Prep everything and assemble in the baking dish, cover, and refrigerate until ready to bake.
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
- Reheating: Warm in the oven until heated through, or in the microwave for a quick option.
