Ingredients

Scale

For the Pasta

  • 12 ounces pasta (such as fettuccine or linguine)

For the Sauce and Vegetables

  • 2 tablespoons olive oil
  • 2 medium leeks (white and light green parts only), thinly sliced
  • 8 ounces cremini mushrooms, sliced
  • 3 cloves garlic, minced
  • 1/2 cup dry white cooking broth (or vegetable stock)
  • 1/2 cup heavy cream
  • 1 cup shredded Gruyere cheese
  • 1/4 teaspoon freshly ground black pepper
  • Salt, to taste
  • 1/4 cup chopped fresh parsley (optional, for garnish)

Instructions

  1. Cook the Pasta: Boil a large pot of salted water and cook the pasta according to the package instructions until al dente. Reserve 1/2 cup of the pasta water before draining to use later for adjusting sauce consistency.
  2. Heat the Oil: In a large skillet, heat the olive oil over medium heat to prepare for sautéing the vegetables.
  3. Caramelize the Leeks: Add the sliced leeks to the skillet and cook for 6-8 minutes, stirring occasionally, until they become soft and golden, developing a lovely caramelized flavor.
  4. Sauté the Mushrooms: Stir in the sliced cremini mushrooms and continue cooking for another 5-7 minutes until the mushrooms are tender and slightly browned, enhancing their earthy taste.
  5. Add Garlic: Add the minced garlic to the skillet and sauté for 1 minute until fragrant, taking care not to burn it.
  6. Deglaze the Pan: Pour in the dry white cooking broth and stir well, scraping up any browned bits from the bottom of the skillet. Let the mixture simmer for 2 minutes to concentrate flavors.
  7. Add Cream: Stir in the heavy cream, reduce the heat to low, and let the sauce simmer gently for 3-4 minutes until it thickens slightly.
  8. Incorporate Gruyere Cheese: Gradually add the shredded Gruyere, stirring continuously until the cheese melts completely into the sauce. Season with salt and freshly ground black pepper to taste.
  9. Combine with Pasta: Toss the drained pasta into the skillet with the sauce. Add reserved pasta water as needed to loosen and achieve your desired sauce consistency, ensuring every strand is coated.
  10. Garnish and Serve: Sprinkle the dish with chopped fresh parsley if using, and serve immediately for the best flavor and texture.

Notes

  • To ensure even cooking, trim and clean leeks thoroughly as dirt can hide between the layers.
  • Reserved pasta water is starchy and helps bind the sauce to the pasta, so don’t discard it.
  • For a lighter version, substitute heavy cream with half-and-half, but the sauce will be less rich.
  • Gruyere cheese can be replaced with Emmental or Swiss cheese if desired.
  • This recipe is best served immediately as the sauce thickens upon standing.
