Instructions
1
Preheat oven to 375°F (190°C).
2
In a skillet over medium heat, melt 1 tablespoon butter. Add 1 tablespoon minced garlic and sauté until fragrant, about 1 minute. Stir in cooked chicken, Italian seasoning, salt, and pepper, combining thoroughly. Remove from heat and allow to cool slightly.
3
In a mixing bowl, blend ricotta cheese, 1 cup shredded mozzarella, 1 cup grated Parmesan, and the seasoned chicken mixture until evenly incorporated.
4
In a saucepan over medium heat, melt 4 tablespoons butter. Add 3 minced garlic cloves and cook for 1-2 minutes until aromatic. Stir in heavy cream, salt, and pepper. Simmer for 5 minutes, then gradually whisk in 1 cup grated Parmesan, stirring until the sauce is smooth and creamy.
5
Spread 1 cup of Alfredo sauce evenly over the bottom of a 9×13-inch baking dish. Stuff each cooked jumbo pasta shell with the chicken and cheese filling and arrange them in the prepared dish.
6
Pour remaining Alfredo sauce over the stuffed shells and sprinkle with additional shredded mozzarella cheese. Bake uncovered for 25 minutes, or until the cheese is fully melted and bubbling.
7
Remove baking dish from oven. Garnish with freshly chopped parsley if desired, and serve immediately while hot.
Essential Tips
Don't overcook pasta
Cook the jumbo shells until they're al dente by 1 minute-they'll finish baking in the oven. Overcooked shells turn mushy when baked.
Brown the chicken first
For deeper flavor, brown your cooked chicken in the garlic butter before mixing with ricotta. This adds Maillard reaction flavors to the filling.
Warm your sauce
Before baking, warm the Alfredo sauce slightly so it's hot when poured over the shells-this prevents temperature shock that can make shells tough.
Press shells gently
When stuffing shells, press lightly to compact filling but don't overstuff or they may burst during baking. Aim for 75% full.
Add cheese after baking
Sprinkle extra mozzarella on just before baking so it melts beautifully without creating a gluey top layer.
Smart Swaps & Variations
Lighter Alfredo
Swap heavy cream for half-and-half and use low-fat ricotta and mozzarella-still creamy but with 20% fewer calories while maintaining texture.
Spicy Kick
Add 1/2 teaspoon red pepper flakes to the garlic butter in step 2, or stir in 1 tablespoon of hot sauce with the Alfredo cream.
Vegetarian
Replace chicken with sautéed mushrooms, spinach, and roasted butternut squash-use 3 cups total for similar volume to chicken.
Seafood Twist
Substitute shrimp for chicken and add 1/2 teaspoon smoked paprika to the Alfredo sauce for a sophisticated surf-and-turf feel.
What to Serve With This
- Garlic bread and a simple arugula salad dressed with lemon vinaigrette to cut through the richness.
- A crisp Pinot Grigio or Chardonnay to complement the creamy sauce and chicken.
- Steamed broccoli or roasted asparagus for a fresh, green contrast.
- Fresh basil sprigs scattered on top for a pop of color and herbal aroma.
Storage & Reheating
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. The shells will absorb some sauce over time, so add a splash of warm milk when reheating to restore creaminess.
Reheating
Cover with foil and warm in a 350°F (175°C) oven for 15 minutes to prevent the pasta from drying out. Microwaving works but often makes the shells rubbery-avoid unless in a pinch.
Expert Chef Tips
- Use whole milk ricotta for the filling-it has better texture and fat distribution than part-skim, which can make the mixture grainy.
- For extra richness, deglaze the chicken-skillet with 1/4 cup of the warm Alfredo sauce before mixing with ricotta-this captures all the fond flavors.
- If making ahead, under-stuff the shells slightly as they'll swell during refrigeration. Add 5 minutes to baking time if assembling the dish a day ahead.
Equipment You’ll Need
- 9×13-inch glass or ceramic baking dish (preferably non-reactive)
- Medium skillet for cooking garlic and chicken
- Medium saucepan for making Alfredo sauce
- Mixing bowl for combining filling ingredients
- Small spoon or piping bag for stuffing shells

Frequently Asked Questions
Can I use fresh pasta shells instead of dried?
Yes, but reduce cooking time by about 2 minutes since fresh pasta cooks faster. Test at 8 minutes for doneness. Also, they're more delicate so handle gently when stuffing to avoid tearing.
What's the best way to shred chicken evenly?
Use two forks to pull apart cooked chicken while it's still warm-this creates natural shreds. For diced chicken, cool completely first then cut into 1/4-inch pieces for more uniform texture in the filling.
Can I make this ahead and bake later?
Absolutely! Assemble the dish completely, cover tightly with foil, and refrigerate for up to 24 hours. Add 10 minutes to baking time and remove foil for the last 5 minutes to crisp the top.
How do I prevent the shells from getting soggy?
Cook them al dente and bake immediately after stuffing. Also, spread a thin layer of sauce on the bottom of the dish to create a moisture barrier, and avoid overcrowding in the baking dish.
What's a good substitute for heavy cream?
For richness without the fat, use 1 cup whole milk mixed with 1/2 cup melted butter. For dairy-free, blend 1 cup full-fat coconut milk with 1/4 cup nutritional yeast-it mimics the richness surprisingly well.
Can I freeze this dish?
Yes, freeze baked portions in airtight containers for up to 3 months. Thaw overnight in the fridge then reheat covered in a 350°F oven for 20 minutes. Freezing before baking isn't recommended as the pasta becomes mushy when thawed.
How can I make the Alfredo sauce thicker?
Simmer the sauce uncovered for 2-3 minutes longer to reduce slightly. For instant thickening, make a quick beurre manié by whisking 1 tablespoon flour into 1 tablespoon softened butter, then stirring this into the hot sauce.
What's the best way to stuff the shells without breaking them?
Use a small spoon or piping bag to fill shells from the larger end first. Hold the shell steady with a fork while filling to prevent pressure from causing cracks. Work over a plate to catch any filling that falls out.
