Creamy Chestnut Pasta with Parmesan, Garlic, and Thyme (Print version)

A cozy vegetarian pasta with sweet chestnuts, garlic, thyme, cream, and Parmesan tossed through wide ribbons of pasta.

# Ingredients:

For the pasta

01 - 12 oz (340 g) pappardelle or fettuccine
02 - 1 tablespoon kosher salt, for the pasta water
03 - 1 cup (240 ml) reserved pasta water

For the chestnut cream sauce

04 - 2 tablespoons unsalted butter
05 - 1 tablespoon extra-virgin olive oil
06 - 1 medium shallot, finely chopped
07 - 3 garlic cloves, minced
08 - 1 tablespoon fresh thyme leaves, plus more for serving
09 - 1 cup (150 g) cooked peeled chestnuts, roughly chopped
10 - 1/2 cup (120 ml) low-sodium vegetable broth
11 - 1 cup (240 ml) heavy cream
12 - 1/2 cup (50 g) freshly grated Parmesan cheese, plus more for serving
13 - 1/4 teaspoon freshly grated nutmeg, optional
14 - 1/2 teaspoon fine salt, plus more to taste
15 - 1/2 teaspoon freshly ground black pepper
16 - 1 teaspoon finely grated lemon zest

For serving

17 - 1/4 cup (25 g) toasted walnuts, chopped, optional
18 - Fresh thyme leaves
19 - Extra Parmesan cheese

# Instructions:

01 - Bring a large pot of water to a boil and season it well with kosher salt. Cook the pasta until just shy of al dente, then reserve 1 cup of pasta water and drain.
02 - Set a wide skillet over medium heat. Add the butter and olive oil, then cook the shallot with a pinch of salt for 3-4 minutes until soft. Stir in the garlic and thyme and cook for 45 seconds.
03 - Add the chopped chestnuts and cook for 2-3 minutes, stirring often. Mash some of the pieces with the back of a spoon so they help thicken the sauce.
04 - Pour in the vegetable broth and scrape up the skillet. Add the heavy cream and simmer gently for 4-5 minutes until slightly thickened.
05 - Lower the heat. Stir in Parmesan, nutmeg if using, fine salt, black pepper, and lemon zest until the cheese melts into the sauce.
06 - Add the drained pasta and toss well. Add reserved pasta water a few tablespoons at a time until the sauce is glossy and coats the noodles.
07 - Taste and adjust salt and pepper. Serve immediately with toasted walnuts, fresh thyme, and extra Parmesan.

# Good to know:

01 - Use cooked peeled chestnuts, not raw chestnuts.
02 - Best served as soon as the pasta is tossed.
03 - Reserve pasta water before draining because the sauce thickens quickly.
