There’s something about stuffed pasta shells that just feels like a warm hug on a plate. When I was growing up, my mom would often make pans of cheesy stuffed shells for family dinner or to take to a potluck. Either way, they always meant one thing: comfort.
This stuffed shells recipe with tender chicken, crisp broccoli, and creamy Alfredo sauce is my family’s favorite twist on the classic. It’s rich and satisfying, but still easy enough for a busy weeknight. Bonus: it makes fantastic leftovers for lunch the next day (if there are any left!).

Prep time: 10 minutes
Cook time: 40 minutes
Serves: 4
Ingredients:

- 2 c. broccoli florets, fresh or frozen
- 8 oz. jumbo shells
- 2 T. butter
- 2 garlic cloves, minced
- 1 c. whole milk
- 1/2 c. heavy cream
- 1/2 c. parmesan cheese, freshly grated
- 2 c. mozzarella cheese, freshly grated, divided
- 1-1/2 c. cooked, shredded chicken – rotisserie chicken works really well here!
- 1/2 t. garlic powder
- 1/2 c. fresh parsley, chopped
- Sea salt and black pepper to taste

Directions for these easy chicken Alfredo stuffed shells:
- Preheat oven to 350°F. Lightly grease a casserole dish with olive oil. Set aside.
- Bring a large pot of salted water to a rolling boil over medium heat.
- Add broccoli florets and cook 2 minutes. Scoop broccoli out of water with a spider skimmer or slotted spoon into a colander. Rinse with cool water to stop cooking.
- Add pasta shells to boiling water and cook according to package directions just until al dente. Reserve 1/2 cup of pasta water and set aside.
- Drain cooked shells and run under cool water to prevent overcooking.
- In the meantime, melt butter in a medium saucepan over medium heat. Add minced garlic, whole milk, and heavy cream. Bring to a simmer.
- Remove from heat and stir in parmesan and 1 cup of mozzarella cheese. Whisk until the cheese is all melted and the sauce is smooth. Season with salt and pepper to taste.
- Rough chop broccoli and add to a medium mixing bowl.
- Add shredded chicken, garlic powder, parsley, and the alfredo sauce. If mixture seems too thick, add a bit of pasta water to thin out (2 Tablespoons should do it).
- Toss together with a large spoon. Season with salt and pepper, to taste.
- Fill each pasta shell with a tablespoon of the chicken alfredo mixture and arrange them in the prepared baking dish. Spread any leftover stuffing mixture on top of the shells and cover with the remaining mozzarella cheese.
- Bake pasta shells uncovered until golden-brown and bubbly, 20-25 minutes. Let cool 5 minutes, then serve and enjoy!
FAQs
Can I make these stuffed shells ahead of time?
Yes! Assemble the shells and cover tightly. Store in the fridge for up to 24 hours or freeze for up to 3 months. Bake straight from the fridge (add a few extra minutes) or thaw overnight before baking.
Can I use frozen broccoli?
Absolutely. Just thaw and drain it well before adding it to the filling to avoid excess water.
What’s the best substitute for heavy cream?
You can use more whole milk, though the sauce won’t be quite as rich. Adding a tablespoon of cream cheese can help mimic the creaminess.
Can I use store-bought Alfredo sauce?
You can — but I promise the homemade version in this recipe is super simple and much more flavorful.
How do I store and reheat leftovers?
Store in an airtight container in the fridge for up to 3 days. Reheat in the microwave or in a covered dish in the oven at 325°F until warmed through.
Can I make these stuffed shells with rotisserie chicken?
You sure can! I do that all the time. Or purchase the shredded chicken from the store or grab some boneless skinless chicken breasts. Poach and shred them. You can also make use of leftover chicken. I often roast two chickens, using one for dinner and cutting up the other one to use in recipes like this.
This chicken and broccoli casserole is a twist on the classic stuffed shells. I hope this recipe brings your family as much comfort and joy as it does mine. It’s the kind of dish that feels like a little celebration, even on an ordinary weeknight.
