Ingredients

Scale

Vegetables and Aromatics

  • 3 medium leeks, tops removed, cut in half and thinly sliced
  • 8 ounces oyster mushrooms
  • 4 garlic cloves, minced
  • 2 sage leaves
  • 1 teaspoon lemon zest

Liquids and Dairy

  • 2 tablespoons olive oil
  • 3 tablespoons butter, divided
  • ⅓ cup sherry wine
  • ¾ cup heavy cream
  • 1 tablespoon balsamic vinegar
  • ½ cup grated Gruyere cheese

Dry Ingredients and Seasonings

  • ½ teaspoon salt, plus more to taste
  • ½ teaspoon granulated sugar
  • 1 teaspoon black pepper, plus more to taste
  • 1 pound fettuccine pasta
  • ¼ cup toasted pine nuts
  • 1 cup reserved pasta water

Instructions

  1. Caramelize the Leeks: Heat 2 tablespoons olive oil and 2 tablespoons butter in a large sauté pan over medium heat. Add the sliced leeks and season with ½ teaspoon salt and ½ teaspoon sugar. Cook slowly until the leeks become golden and caramelized, about 20 minutes, stirring occasionally. Add 1-2 tablespoons of water if the pan becomes too dry to prevent sticking.
  2. Deglaze with Sherry: Pour in the ⅓ cup sherry wine and continue cooking until the liquid reduces and evaporates. Once done, remove the caramelized leeks from the pan and set aside.
  3. Sauté the Mushrooms: In the same pan, melt the remaining 1 tablespoon of butter. Spread the oyster mushrooms out in an even layer, ensuring they have space between them to brown properly. Let them cook undisturbed for about 4 minutes until browned on one side, then flip and brown the other side. Season with salt and black pepper to taste.
  4. Add Garlic and Sage: Add the minced garlic and sage leaves to the mushrooms and sauté for 1 minute until fragrant. Then return the caramelized leeks to the pan.
  5. Make the Cream Sauce: Pour in the heavy cream, balsamic vinegar, and lemon zest. Bring the mixture to a simmer and cook for 2-3 minutes until the sauce thickens slightly. Season with additional salt and pepper to taste.
  6. Cook the Pasta: While the sauce simmers, bring a large pot of salted water to a boil and cook the fettuccine according to package instructions until al dente. Reserve 1 cup of pasta cooking water before draining the pasta.
  7. Combine Pasta and Sauce: Add the cooked fettuccine to the sauce along with the reserved pasta water, grated Gruyere, and black pepper. Toss thoroughly to coat the pasta evenly. Simmer for 2 minutes until the cheese is melted and the sauce is creamy and adheres well to the noodles. Adjust seasoning with salt and pepper if needed.
  8. Serve and Garnish: Portion the pasta into 4 bowls and sprinkle with toasted pine nuts for added texture and flavor. Serve immediately while warm.

Notes

  • You can substitute the oyster mushrooms with cremini, button, chanterelle, or any mushroom mix available.
  • If preparing ahead, complete steps 1-4 for the sauce. Reheat the sauce gently before tossing with freshly cooked pasta.
