Brown Butter Pumpkin Alfredo with Toasted Pecan-Sage Crunch
A toasted pecan and crispy fried sage topping gives this deeply savory, autumnal pasta a much-needed textural crunch. By swapping standard milk for a richer blend of heavy cream and starchy pasta water, the pumpkin sauce forms a glossy, stable emulsion that clings perfectly to every strand of fettuccine without separating.

Ingredients
Scale
Pasta & Produce
- 12 oz (340 g) dried fettuccine or pappardelle pasta
- 1 1/4 cups (300 g) pure pumpkin purée (not pumpkin pie filling)
- 1/4 cup (10 g) fresh sage leaves, loosely packed
- 4 large garlic cloves, minced
Pecan-Sage Crunch
- 4 tablespoons (56 g) unsalted butter
- 1/3 cup (40 g) chopped pecans
Alfredo Sauce
- 1/4 cup (60 ml) dry white wine (such as Pinot Grigio or Sauvignon Blanc)
- 3/4 cup (180 ml) heavy cream
- 1 1/4 cups (125 g) freshly grated Parmigiano-Reggiano, plus more for serving
- 1/2 teaspoon crushed red pepper flakes
- 1/4 teaspoon ground nutmeg
- Kosher salt and freshly ground black pepper, to taste
Instructions
- Boil the pasta: Bring a large pot of heavily salted water to a boil. Cook the fettuccine according to package directions until al dente. Reserve 1 cup of the starchy pasta water, then drain the pasta and set aside.
- Fry the topping: In a large, deep skillet over medium heat, melt the butter. Once foaming, add the fresh sage leaves and chopped pecans. Cook, stirring constantly, until the butter turns a deep nutty brown, the sage is crisp, and the pecans are fragrant, about 3 to 4 minutes. Using a slotted spoon, carefully transfer the sage and pecans to a paper towel-lined plate. Leave the browned butter in the skillet.
- Aromatics and deglaze: Reduce the heat under the skillet to medium-low. Add the minced garlic and crushed red pepper flakes to the browned butter, stirring for 30 seconds until highly fragrant. Pour in the white wine to deglaze the pan, scraping up any browned bits from the bottom, and let it bubble and reduce for 1 minute.
- Build the sauce: Whisk the pumpkin purée and heavy cream into the skillet until smooth. Bring the mixture to a very gentle simmer and let it cook for 2 minutes so the flavors marry and the sauce thickens slightly.
- Emulsify the cheese: Turn off the heat entirely. Whisking continuously, add the grated Parmigiano-Reggiano a handful at a time. Pour in 1/2 cup of the reserved hot pasta water to help melt the cheese smoothly into a glossy sauce. Stir in the nutmeg, and season generously with kosher salt and black pepper to taste.
- Toss and serve: Add the drained fettuccine to the skillet, tossing vigorously with tongs for about 1 minute to coat the noodles completely. If the sauce feels too thick, splash in a little more reserved pasta water until it reaches a silky consistency. Divide into warm bowls, crush the reserved crispy sage and pecans over the top, garnish with additional Parmigiano-Reggiano, and serve immediately.
Notes
- Why it works: Heavy cream contains enough fat to stabilize the sauce, preventing the acidic pumpkin purée and wine from causing the dairy to curdle or turn grainy—a common issue when using lower-fat milk.
- Cheese warning: Always grate your Parmigiano-Reggiano from a block. Pre-shredded bagged cheeses are coated in anti-caking agents (like cellulose) that will refuse to melt smoothly, leaving your Alfredo gritty.
