Ingredients

Scale

Pasta

  • 12 ounces pasta (such as fettuccine or linguine)

Vegetables & Aromatics

  • 2 medium leeks (white and light green parts only), thinly sliced
  • 8 ounces cremini mushrooms, sliced
  • 3 cloves garlic, minced

Liquids & Dairy

  • 2 tablespoons olive oil
  • 1/2 cup dry white cooking broth (or vegetable stock)
  • 1/2 cup heavy cream
  • 1 cup shredded Gruyere cheese

Seasoning & Garnish

  • 1/4 teaspoon freshly ground black pepper
  • Salt, to taste
  • 1/4 cup chopped fresh parsley (optional, for garnish)

Instructions

  1. Prepare 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 the pasta.
  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 thinly sliced leeks to the skillet and cook for 6 to 8 minutes, stirring occasionally, until the leeks are soft, translucent, and golden in color.
  4. Sauté the Mushrooms: Add the sliced cremini mushrooms to the skillet and cook for an additional 5 to 7 minutes, stirring occasionally, until the mushrooms are tender and have browned slightly.
  5. Add Garlic: Stir in the minced garlic and sauté for about 1 minute until the garlic becomes fragrant but not burnt.
  6. Deglaze the Pan: Pour in the white cooking broth or vegetable stock, stirring to scrape up any browned bits on the bottom of the skillet. Let it simmer for 2 minutes to reduce slightly and concentrate flavors.
  7. Add Cream: Reduce the heat to low and stir in the heavy cream. Allow the mixture to simmer gently for 3 to 4 minutes until it thickens slightly.
  8. Incorporate Gruyere Cheese: Gradually add the shredded Gruyere, stirring continuously to help the cheese melt smoothly into the sauce. Season with salt and freshly ground black pepper to taste.
  9. Mix with Pasta: Add the cooked pasta directly into the skillet with the sauce and toss to combine thoroughly. Add reserved pasta water as needed to loosen the sauce to your preferred consistency.
  10. Garnish and Serve: Sprinkle chopped fresh parsley over the pasta if desired, and serve immediately while hot.

Notes

  • Use the white and light green parts of the leeks only to avoid bitter taste from the dark green parts.
  • If you do not have white cooking broth, a dry white wine or vegetable stock can be used as an alternative for deglazing.
  • Adjust the reserved pasta water quantity gradually to control the sauce thickness.
  • For a lighter version, substitute heavy cream with half-and-half or a creamy plant-based alternative.
  • Gruyere cheese can be replaced with Swiss cheese or fontina for a similar flavor.
  • This dish pairs well with a crisp green salad or steamed vegetables for a complete meal.
