Ingredients You’ll Need

• 1 12 oz box jumbo pasta shells
• 1 cup prepared peppercorn ranch or ranch dressing
• 4 oz chive and onion cream cheese, softened
• 1 tsp dry Italian seasoning
• 1/2 tsp red pepper flakes
• 2 cups rotisserie chicken, chopped
• 2 cups steamed broccoli florets, roughly chopped
• 1/4 cup grated Parmesan cheese
• 1 tsp granulated garlic or garlic powder
• 1/2 tsp salt
• 1/2 tsp black pepper
• 2 cups shredded mozzarella cheese, divided
• 1 16 oz jar prepared Alfredo sauce
• 1 Tbsp chopped Italian parsley for garnishing

How to Assemble and Bake

1. Preheat oven to 350°F and spray a 13 x 9-inch baking dish with cooking spray.
2. Bring a large pot of salted water to a boil and cook 12 oz jumbo pasta shells per package directions until al dente; drain, rinse briefly with cool water, and cool until you can handle them.
3. In a medium bowl, beat 1 cup prepared peppercorn ranch, 4 oz softened chive-and-onion cream cheese, 1 tsp dry Italian seasoning, and 1/2 tsp red pepper flakes with a hand mixer until smooth.
4. Stir in 1/4 cup grated Parmesan, 2 cups chopped cooked chicken, 2 cups steamed chopped broccoli, and 1 cup shredded mozzarella; season with 1 tsp granulated garlic, 1/2 tsp salt, and 1/2 tsp black pepper and adjust to taste.

5. Spoon the chicken-and-broccoli filling into each shell using a tablespoon and arrange the filled shells side by side in the prepared baking dish.

6. Pour a 16 oz jar of Alfredo sauce evenly over the stuffed shells.
7. Sprinkle the remaining 1 cup shredded mozzarella over the sauce.
8. Bake uncovered at 350°F for 35–40 minutes, until the sauce bubbles and the cheese is lightly golden.
9. Remove from the oven, sprinkle with chopped Italian parsley, and let rest about 5 minutes before serving.

Cooking and Serving Tips

• Cook your shells just until al dente so they stay sturdy when filled. Overcooked shells can fall apart while baking.
• Drain shells fully and let them cool a bit before filling to avoid tearing. Use tongs or a spoon to handle them gently.
• If using frozen broccoli, thaw and drain completely or steam until tender-crisp to avoid watery filling.
• For a smoother filling texture, shred the chicken finely or pulse it briefly in a food processor.
• If you want less salt or less tang, use a milder ranch or cut back on the amount, then season with salt accordingly.
• If cheese browns too fast during baking, cover loosely with foil for the first 20-25 minutes, then remove foil to finish baking and brown.
• Try swapping or mixing in cheeses like ricotta, provolone, or an Italian blend for different texture and flavor—just keep the total cheese amount about the same; for a ricotta-forward variation, see Sun-Dried Tomato and Ricotta Stuffed Shells.
• If making ahead and refrigerating, let the assembled dish sit 15 minutes at room temperature before baking, and add a few extra minutes to the baking time if going in cold. For serving, pair the shells with a fresh side like Peach and Goat Cheese Salad.

Flavor Swaps and Add-Ins

Making chicken and broccoli stuffed shells is an easy, cost-effective way to feed the family. Pasta dishes like these really stretch your grocery dollars without skimping on flavor or comfort. If you want to switch things up, here are some ideas you might like:

• Try different stuffed shells recipes with various fillings like spinach and ricotta—these tofu ricotta stuffed shells with spinach are a great option—or sausage and cheese to keep dinner interesting.

Keep and Reheat Leftovers

Refrigerator: Keep any leftover baked chicken and broccoli stuffed shells in a sealed container in the fridge for up to 3 days.

To reheat: Microwave individual portions until hot, or warm them in a 350°F oven covered with foil for 15–20 minutes (add time if very cold) until heated all the way through.

Make-ahead & Freezing: You can assemble these stuffed shells (unbaked), cover tightly, and refrigerate for up to 24 hours before baking. For longer storage, prepare and freeze the unbaked dish in a freezer-safe container for up to 2 months. Thaw in the refrigerator overnight before baking, then add 10–15 minutes to baking time. Another option is to bake fully, cool completely, and freeze portions or the entire casserole for up to 2 months. To reheat from frozen, bake covered at 350°F until warmed through (usually 45–60 minutes), checking that the internal temperature hits 165°F.

Troubleshooting and Swaps

• Can I use fresh broccoli? Absolutely! Just chop into small florets and steam until tender-crisp before mixing in, so it’s not crunchy after baking.
• Do I have to use rotisserie chicken? No, any cooked chicken works great—leftover roasted, poached, or even grilled chicken. You could also swap with cooked turkey or a plant-based protein if you prefer.
• Can I swap ricotta for the cream cheese? Yes, you can replace part or all of the cream cheese with ricotta for a lighter texture, but you might want to tweak the seasonings to keep the flavor just right.
• Is homemade Alfredo sauce okay to use? Definitely! Using your favorite homemade Alfredo sauce will add fresh flavor that’s fantastic in this dish.
• How many shells does this recipe make? This recipe makes about 36 jumbo stuffed shells, based on the 12-ounce box of pasta. You can double or halve the ingredients if you want to make more or less.
• Can I make this gluten-free? Yes, just use gluten-free jumbo pasta shells and check that your dressings and sauces are gluten-free.
• How do I prevent the dish from becoming watery? Make sure your broccoli is well drained and your shells aren’t overcooked. Stick to the recipe amounts for sauce and don’t add extra liquid ingredients.
