How to Make the Best Stuffed Shells with Pumpkin Sauce
These stuffed shells with pumpkin sauce are the ultimate fall comfort food, combining tender pasta shells filled with savory Italian sausage, creamy ricotta, and melted mozzarella, all nestled in a velvety pumpkin Parmesan sauce. The sauce is subtly sweet with warming notes of nutmeg that perfectly complement the savory filling.
What makes this dish special is the homemade pumpkin sauce—it’s incredibly silky and rich without being heavy. Roasting your own winter squash adds a depth of flavor that canned pumpkin simply can’t match, though the convenience of canned works beautifully when you’re short on time. The fresh sage in the filling adds an aromatic quality that screams autumn.
This recipe is wonderfully adaptable for vegetarians—simply swap the Italian sausage for extra mushrooms or your favorite plant-based alternative. Either way, you’ll end up with a stunning dish that’s perfect for holiday gatherings or a cozy weekend dinner with the family.

Instructions
Prepare the Squash and Shells
- Preheat oven to 425°F.
- Cut winter squash in half, scrape out seeds, and roast open side down on a parchment-lined baking sheet for 35-45 minutes, until easily pierced with a knife.
- In the meantime, boil water for shells and cook according to package directions. Drain, coat with olive oil, and set aside.
Make the Filling
- Brown the sausage in a heavy-bottomed skillet over medium heat. Set aside on a paper-lined plate and wipe out the skillet.
- Heat 1-2 tablespoons olive oil and sauté onions over medium heat until golden and tender.
- Add garlic and optional mushrooms. Sauté on medium-low heat until mushrooms are tender.
- Add sage, sauté for one minute, then turn off heat.
- Return sausage to the pan and stir in pine nuts (if using), ricotta, and mozzarella. Taste for salt and add 1/4-1/2 tsp kosher salt if needed, plus cracked pepper. Set aside.
Make the Pumpkin Sauce
- When pumpkin is done, remove from oven and reduce heat to 350°F.
- Spoon 2 cups of roasted squash into a blender with cold chicken stock, milk, Parmesan, salt, sugar, nutmeg, and pepper.
- Blend until very smooth and silky.
Assemble and Bake
- In a large greased baking dish (or individual ramekins), pour enough sauce to coat the bottom.
- Stuff the shells with the filling and place them in the baking dish over the sauce.
- Pour more sauce over top. Cover with foil and bake at 350°F until heated through, about 20 minutes.
- Remove foil and continue baking another 10 minutes. Add more cheese or remaining sauce to the top if desired.
Notes
- For a vegetarian version, substitute the sausage with additional mushrooms or plant-based sausage.
- Any winter squash works well: butternut, acorn, kuri, or delicata.
- Canned pumpkin puree can be used as a shortcut instead of roasting fresh squash.
