Ingredients

Scale

Vegetables and Herbs

  • 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
  • 1 teaspoon black pepper
  • ½ teaspoon salt (plus additional for seasoning)
  • ½ teaspoon granulated sugar

Dairy and Oils

  • 2 tablespoons olive oil
  • 3 tablespoons butter divided
  • ¾ cup heavy cream
  • ½ cup grated Gruyere cheese

Liquids and Others

  • ⅓ cup sherry wine
  • 1 tablespoon balsamic vinegar
  • 1 lb fettuccine
  • 1 cup reserved pasta water
  • ¼ cup toasted pine nuts


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, stirring occasionally, until golden and caramelized, about 20 minutes. Add 1-2 tablespoons of water if the pan gets too dry to prevent burning.
  2. Reduce the sherry wine: Add the ⅓ cup sherry wine to the caramelized leeks and cook until the wine has reduced. Remove the leeks from the pan and set aside.
  3. Brown the mushrooms: In the same pan, melt the remaining 1 tablespoon of butter. Spread the oyster mushrooms evenly in the pan, giving them space to brown. Cook without moving for about 4 minutes until they brown on one side. Flip and continue browning on the other side. Season with salt and pepper to taste.
  4. Sauté garlic and sage: Add the minced garlic and sage leaves to the mushrooms and sauté for 1 minute until fragrant.
  5. Make the sauce: Return the caramelized leeks to the pan and add ¾ cup heavy cream, 1 tablespoon balsamic vinegar, and lemon zest. Bring to a simmer and cook until thickened, about 2-3 minutes. Season the sauce with salt and pepper to taste.
  6. Cook the pasta: Meanwhile, cook 1 lb fettuccine in boiling salted water until al dente according to package instructions. Reserve 1 cup of pasta cooking water before draining.
  7. Combine pasta and sauce: Add the cooked fettuccine, reserved pasta water, ½ cup grated Gruyere cheese, and black pepper to the sauce. Toss well to coat the pasta evenly with the sauce. Simmer for 2 minutes until the cheese melts and the sauce thickens further. Adjust seasoning with salt and pepper.
  8. Serve: Portion the pasta into 4 bowls and garnish with ¼ cup toasted pine nuts. Serve immediately for the best flavor and texture.

Notes

  • You can substitute oyster mushrooms with cremini, button, chanterelle, or a mixed variety of mushrooms based on availability and preference.
  • For advance preparation, make the sauce up to step 5 and refrigerate. Reheat gently before tossing with freshly cooked pasta.
  • If you want a lighter version, consider reducing the butter and cream slightly or using half-and-half instead of heavy cream.
  • To toast pine nuts, dry roast them in a skillet over medium heat for 2-3 minutes until golden and fragrant, stirring frequently to prevent burning.
  • Be sure to reserve pasta water as it helps to create a creamy sauce by adding starch.
