Easy Fall Pasta with Roasted Pumpkin Sauce
White Pumpkin Fettuccine Alfredo offers a luxurious twist on classic Alfredo pasta that’s perfect for fall and winter. This recipe combines the familiar richness of traditional Alfredo sauce with the subtle sweetness and earthy depth of roasted white pumpkin purée. The result is a creamy, seasonal pasta dish that blends Italian-inspired traditions with contemporary farm-to-table cooking.
White pumpkin is a mild, slightly sweet fall vegetable that adds body and natural color to the Alfredo sauce without overpowering it. Roasting the pumpkin deepens its flavor and brings out caramelized sweetness. Once roasted and blended smooth, the pumpkin becomes the base for a rich, velvety sauce that coats every strand of fettuccine.
What is White Pumpkin?
White pumpkin, also known as ghost pumpkin or Casper pumpkin, is a variety of pumpkin with smooth, pale white skin. Unlike traditional orange pumpkins, white pumpkins have a milder, less sweet flavor that makes them ideal for savory dishes like pasta, soup, and risotto. They’re popular for both cooking and decorative purposes, especially during fall and winter months. If you can’t find white pumpkin, butternut squash or Delicata squash work as substitutes.
How to Make White Pumpkin Alfredo Sauce
The sauce comes together in one skillet. Garlic and shallot are first sautéed in butter until fragrant, providing a savory foundation that complements the pumpkin’s natural sweetness. Heavy cream is added next, along with the roasted pumpkin purée, forming a rich, velvety sauce that coats each strand of pasta.
Parmesan cheese, a staple in traditional Alfredo, gets folded in next, lending a nutty, salty complexity that enhances the creaminess. A dash of nutmeg adds warmth and subtle spice, making each bite feel cozy and seasonal. Fresh thyme brings a slightly minty, peppery flavor that pairs beautifully with white pumpkin and complements the Parmesan.
Reserved pasta water gets added to loosen the sauce to the perfect consistency. This starchy water helps the sauce cling to the fettuccine and creates a silky, restaurant-quality finish.
Toppings and Garnishes
Once the pumpkin Alfredo sauce is ready, it’s tossed with cooked fettuccine pasta. The wide, flat noodles cling to the sauce perfectly, ensuring every bite is flavorful. For crunch and visual appeal, the dish gets garnished with toasted pumpkin seeds (pepitas), which add an earthy, nutty flavor that brings out the creaminess of the sauce. Extra Parmesan cheese and a sprinkle of fresh thyme leaves complete the presentation, making this fall pasta both beautiful and delicious.

Ingredients
1 medium white pumpkin
12 ounces fettuccine pasta
2 tablespoons unsalted butter
3 cloves of garlic, minced
1 shallot, finely chopped
1 cup heavy cream
1 cup Parmesan cheese, grated
1/2 teaspoon nutmeg
1 tablespoon fresh thyme
to taste, salt and ground black pepper
for garnish, grated Parmesan cheese
for garnish, toasted pumpkin seeds
Directions
- Prepare the White Pumpkin Purée:
Preheat your oven to 400°F (200°C). Cut the pumpkin in half, remove the seeds and fibers, and place the halves on a baking sheet. Roast for 30-40 minutes, or until fork tender. Scoop out the flesh and purée in a blender or food processor until it’s smooth. Set aside. - Cook the Fettuccine:
Bring a large pot of salted water to a boil, then cook the fettuccine according to package directions until al dente. Reserve 1 cup of pasta water, drain the pasta, and set aside. - Prepare the White Pumpkin Alfredo Sauce:
Melt the butter over medium heat in a large skillet. Add the garlic and shallot and sauté until fragrant, 1-2 minutes. Stir in the white pumpkin purée, and cook for 2-3 minutes to warm through. Add the heavy cream and stir until smooth. Mix in the grated Parmesan cheese until it melts and creates a creamy sauce, 2-3 minutes. Add the nutmeg and fresh thyme, then season with salt and ground black pepper to taste. - Combine with Fettuccine:
Add the cooked fettuccine to the skillet, tossing to coat the pasta evenly with the pumpkin Alfredo sauce. Stir in as much of the reserved pasta water as necessary to thin the sauce. Adjust the seasoning if needed. - Serve:
Divide the fettuccine among serving plates. Garnish with additional Parmesan cheese and toasted pumpkin seeds for added crunch and flavor.
