1.5 pounds pumpkin β peeled, seeded, cut into 0.5-inch cubes
1 tsp fine sea salt
0.5 tsp black pepper β freshly ground
0.5 cup dry white wine
1.25 cups vegetable broth
1 tbsp kosher salt β for boiling pasta water
12 ounces rigatoni pasta
2 tbsp unsalted butter
0.75 cup Parmigiano Reggiano cheese β finely grated, plus more for serving
Instructions
Prepare the pumpkin by peeling, seeding, and cutting it into 0.5-inch cubes; bring a large pot of water to a boil and add the kosher salt.
Heat the olive oil in a wide skillet over medium heat.
Add the onion and cook, stirring, until soft and translucent, 5β7 minutes.
Stir in the garlic, sage, and red pepper flakes and cook until fragrant, about 30 seconds.
Pour in the white wine and simmer until almost evaporated, 2β3 minutes.
Add the cubes, the fine sea salt, the black pepper, and the vegetable broth; bring to a simmer, cover, and cook until the cubes are tender, 12β15 minutes, then uncover and lightly mash some of them with a spoon to thicken.
Meanwhile, cook the rigatoni in the boiling water until al dente, 1β2 minutes shy of package time; reserve 1 cup pasta water and drain.
Raise the skillet heat to medium-high to reduce excess liquid to a saucy consistency, then stir in the butter until glossy.
Add the drained rigatoni and 0.5 cup reserved pasta water; toss over medium heat until the sauce clings, 1β2 minutes, then remove from heat and stir in the Parmigiano Reggiano until creamy, adding a splash more pasta water if needed.
Taste and adjust seasoning if needed, and serve immediately.
