Ingredients
Serves 6
- 24 jumbo pasta shells (about 8 ounces dry)
- 1½ pounds Italian sausage, casings removed
- 4 cups shredded mozzarella cheese, divided
Instructions
Step 1: Prepare the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish to prevent sticking and make cleanup easier.
Step 2: Cook the Pasta Shells
Bring a large pot of salted water to a boil.
Cook the jumbo pasta shells until just slightly under al dente, approximately 1 to 2 minutes less than the package instructions recommend. The shells should be tender enough to handle but firm enough to hold their shape when stuffed.
Drain and rinse briefly under cool water. Arrange the shells on a baking sheet or large plate to prevent them from sticking together.
Step 3: Brown the Sausage
While the pasta cooks, place a large skillet over medium heat.
Add the Italian sausage and cook, breaking it apart with a spoon as it browns. Continue cooking for 7 to 10 minutes, or until the sausage is fully cooked and no pink remains.
Drain excess grease if necessary, leaving a small amount for flavor.
Allow the sausage to cool slightly before moving to the next step.
Step 4: Make the Filling
Add 2 cups of the shredded mozzarella cheese to the warm sausage.
Stir until the cheese begins to melt and combine with the meat, creating a rich and flavorful filling.
Step 5: Stuff the Shells
Using a spoon, fill each cooked pasta shell with a generous amount of the sausage and cheese mixture.
Arrange the stuffed shells in a single layer inside the prepared baking dish, placing them close together to help them stay upright during baking.
Step 6: Add the Cheese Topping
Sprinkle the remaining 2 cups of mozzarella evenly over the stuffed shells.
Make sure the tops are well covered so the cheese melts into a bubbly, golden layer during baking.
Step 7: Bake
Cover the baking dish loosely with aluminum foil, tenting it slightly above the cheese.
Bake for 15 minutes.
Remove the foil and continue baking for an additional 10 to 15 minutes, or until the cheese is fully melted, bubbling, and lightly golden around the edges.
Step 8: Rest and Serve
Remove the dish from the oven and allow it to rest for about 5 minutes before serving.
This brief resting period helps the cheese set slightly and makes the shells easier to serve.
Serve hot and enjoy every bite of the savory sausage filling and gooey melted mozzarella.
Serving Suggestions
These stuffed shells pair beautifully with a variety of side dishes.
Try serving them with:
- Fresh green salad with Italian dressing

- Steamed green beans
- Caesar salad
- Roasted zucchini
For an authentic Italian-inspired presentation, finish each serving with a sprinkle of dried Italian herbs or freshly cracked black pepper.
Helpful Tips
Don’t Overcook the Shells
Slightly undercooking the pasta prevents it from becoming too soft during baking and helps the shells hold their shape.
Use Freshly Shredded Cheese
Freshly shredded mozzarella often melts more smoothly than pre-packaged shredded cheese and creates a creamier texture.
Let the Filling Cool Slightly
Allowing the sausage to cool for a few minutes before mixing in the cheese helps create a better filling consistency.
Easy Variations
Mild or Spicy
Use mild Italian sausage for a family-friendly version or hot Italian sausage for extra flavor and heat.
Turkey Sausage Option
Turkey Italian sausage works well if you’re looking for a lighter version while still maintaining plenty of flavor.
Extra Seasoning
Although the recipe shines with just three ingredients, you can add a sprinkle of Italian seasoning, garlic powder, or black pepper before baking for additional depth.
Crispy Cheese Topping
For a beautifully browned crust, place the dish under the broiler for 1 to 2 minutes at the end of baking. Watch carefully to prevent burning.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days.
To reheat, place the shells in a covered baking dish and warm in a 350°F (175°C) oven until heated through. Individual portions can also be reheated in the microwave.
These stuffed shells also freeze well. Simply cool completely, wrap tightly, and freeze for up to 3 months.
