  • 1/2 cup hazelnuts
  • 1 pound tagliatelle pasta
  • 1 stick unsalted butter
  • 12 sage leaves
  • Salt and freshly ground pepper
  • 1/2 pound mixed mushrooms, such as shiitake, oyster and crimini sliced
  • 1 large clove garlic minced
  • Juice of 1/2 lemon
  • 1/4 cup-1/2 cup reserved pasta water
  • 1/4 cup-1/2 cup grated Parmesan


  1. Preheat oven to 350. Toast hazelnuts in a baking pan on a single layer for 10 -12 minutes, or until lightly colored and skins are blistered. Let cool and chop roughly. Set aside.
  2. In a large pot of salted boiling water, cook the tagliatelle until al dente. Drain, reserving 1/4 cup-1/2 cup starchy pasta water.
  3. Wipe out the pot and return to medium heat. Add butter and begin browning the butter. When the butter is just beginning to smell brown and nutty,  add the sage leaves. Fry for approximately 30 seconds per side and remove when crisp. Season with salt and drain on paper towels. 

  4. Add the mushrooms to the pot and cook as the butter continues to brown, about 4-5 minutes. Season with salt and pepper and add garlic. Cook for another minute.

  5. Reduce heat to low and add the tagliatelle noodles back to the pot along with 1/4 cup of pasta water, lemon juice and Parmesan. Season with salt and pepper and toss thoroughly until cheese is melted and a silky sauce develops. Add the remainder of pasta water if necessary.

  6. To serve, transfer pasta into bowls and top with sage leaves and chopped toasted hazelnuts.

Recipe Notes

  • This mushroom tagliatelle comes together fairly quickly and is pretty failsafe as long as you keep an eye on things. You definitely don’t want your butter to burn while browning or your sage leaves to burn while frying, so stay close during these steps.
  • Make sure to reserve some of your pasta cooking water as it is combined with freshly grated Parmesan and the sage-infused browned butter to form a luscious sauce that coats the pasta evenly. Using starchy pasta water to get more mileage out of a sauce is an age-old Italian trick that I swear by!
  • Everything can be done in one pot, making this a great weeknight meal; simply boil your pasta in a large pot and drain, then wipe out the pot and begin browning the butter in the same pot. When the butter is just beginning to smell brown and nutty,  fry the sage leaves. Remove when crisp and drain on paper towels, then add the mushrooms and garlic and cook those as the butter continues to brown. Lastly, add the tagliatelle noodles back to the pot and toss everything together with the pasta water, Parmesan  and a squeeze of lemon juice for brightness on low heat.
