How to Make Cheesy Chicken Broccoli Shells (Step-by-Step)
This delightful Cheesy Chicken Broccoli Shells is a creamy, dreamy casserole that's sure to be a crowd-pleaser.
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures that by the time you're ready to pop the dish in, your oven is hot and ready to help everything bubble and meld beautifully.
Step 2: Cook the Pasta Shells
Bring a large pot of salted water to a boil. Add your pasta shells and cook according to package instructions until al dente. They should be tender but still have a bit of a bite since they'll continue cooking in the oven. Drain and set aside.
Step 3: Prepare the Broccoli
If using fresh broccoli, steam or blanch the florets until they are bright green and tender-crisp. If you're using frozen, just ensure they're thawed and moisture is squeezed out before adding them to the mix.
Step 4: Combine the Filling
In a large mixing bowl, combine shredded chicken, steamed broccoli, cheddar cheese, and half of the mozzarella cheese along with the cream of chicken soup, milk, garlic powder, onion powder, and a sprinkle of salt and pepper. Stir until everything is evenly coated and luscious.
Step 5: Stuff the Shells
Carefully stuff each pasta shell with the cheesy chicken and broccoli mixture. I use a small spoon to make this process easier, and it helps ensure they're filled to the brim.
Step 6: Assemble
In a greased 9x13-inch baking dish, lay out the stuffed shells snugly. Pour any remaining filling over the shells, if you have it, and sprinkle the rest of the mozzarella on top. For an extra crunch, sprinkle a thin layer of breadcrumbs over everything.
Step 7: Bake
Cover the dish with aluminum foil (to avoid sticking) and bake in the preheated oven for about 25 minutes. After that, remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and slightly golden.

Common Mistakes to Avoid
- Overcooking the pasta: Make sure your shells are al dente, as they'll continue cooking in the oven.
- Using low-quality cheese: Stick to good-quality cheddar and mozzarella for maximum flavor and meltiness.
- Not draining the broccoli properly: Excess moisture can make the dish watery; pat it dry if needed.
Tips and Tricks for Success
- Rotisserie Chicken: Using store-bought rotisserie chicken not only saves time but adds depth of flavor to your dish.
- Make-Ahead Friendly: You can assemble this dish a day ahead and refrigerate it; just add a few extra minutes to the baking time.
- Experiment with Greens: Don't hesitate to throw in additional vegetables like spinach or bell peppers for added nutrition and color!
Variations
- Substitute whole wheat or gluten-free pasta shells for a healthier option.
- Use different types of cheese such as pepper jack for a spicy twist.
- Add cooked bacon or sausage for an extra burst of flavor.
- Incorporate different vegetables like zucchini or peas for variety.
How to Serve
- Serve with a side salad for a balanced meal.
- Pair with garlic bread for a comforting experience.
- Top with fresh herbs like parsley or basil for color and freshness.
- Offer hot sauce or a tangy dipping sauce on the side for added flavor.

Make Ahead and Storage
- Make Ahead: Assemble the dish a day in advance and refrigerate; add a few extra minutes to baking time.
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 4 days.
- Reheating: Reheat in the oven until warmed through for best texture.
