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

Seasonings & Garnish

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

Instructions

  1. Cook the Pasta: Bring a large pot of salted water to a boil and cook the pasta according to package instructions until al dente. Reserve 1/2 cup of the pasta cooking water before draining the pasta.
  2. Heat the Oil: In a large skillet, heat the olive oil over medium heat to prepare for caramelizing vegetables.
  3. Caramelize the Leeks: Add the thinly sliced leeks to the skillet and cook for 6-8 minutes, stirring occasionally, until they are soft and golden brown, enhancing their sweetness.
  4. Sauté the Mushrooms: Stir in the sliced cremini mushrooms and cook for another 5-7 minutes until tender and slightly browned, developing deeper flavor.
  5. Add Garlic: Incorporate the minced garlic and sauté for about 1 minute until fragrant without burning.
  6. Deglaze the Pan: Pour in the white cooking broth, stirring to scrape up any browned bits stuck to the skillet bottom, then let it simmer for 2 minutes to reduce slightly.
  7. Add Cream: Lower the heat to low and stir in the heavy cream, letting the sauce simmer gently for 3-4 minutes until it thickens slightly.
  8. Incorporate Gruyere: Gradually add the shredded Gruyere cheese, stirring continuously until it melts fully into the sauce. Season with salt and freshly ground black pepper to taste.
  9. Mix with Pasta: Toss the cooked pasta with the sauce in the skillet. Add reserved pasta water a little at a time as needed to achieve desired sauce consistency and coating.
  10. Garnish and Serve: Sprinkle chopped fresh parsley on top if desired, then serve the pasta immediately while warm and creamy.

Notes

  • Use the white and light green parts of leeks only to avoid tough textures.
  • Cremini mushrooms add hearty flavor but you can substitute with button or shiitake mushrooms.
  • Reserve pasta water is useful to loosen up the sauce without diluting flavor.
  • For a vegetarian version, ensure the cooking broth is vegetable-based.
  • Gruyere cheese imparts a nutty, creamy flavor; substitutes like Emmental can work but alter taste.
