Ingredients

12 ounces pasta (such as fettuccine or linguine)

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

Step 1: Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Reserve 1/2 cup of the pasta water, then drain the pasta and set aside.

Step 2: Heat the olive oil in a large skillet over medium heat. Add the sliced leeks and cook for 6 to 8 minutes, stirring occasionally, until they become soft and golden.

Step 3: Add the sliced mushrooms to the skillet and cook for another 5 to 7 minutes until tender and slightly browned.

Step 4: Stir in the minced garlic and sauté for 1 minute until fragrant, being careful not to let it burn.

Step 5: Pour in the white cooking broth, scraping the bottom of the skillet to deglaze and lift any browned bits. Let the liquid simmer for 2 minutes.

Step 6: Reduce the heat to low and stir in the heavy cream. Allow the mixture to simmer gently for 3 to 4 minutes until slightly thickened.

Step 7: Gradually add the shredded Gruyere cheese, stirring constantly until it melts fully into the sauce. Season with salt and freshly ground black pepper to taste.

Step 8: Toss the cooked pasta into the skillet with the sauce. Add reserved pasta water in small amounts as needed to reach your preferred sauce consistency.

Step 9: Garnish with chopped fresh parsley if using, and serve immediately while warm.

Tips & Variations

Use vegetable stock to keep the dish vegetarian or swap for chicken broth if preferred for extra depth.

For a nuttier flavor, try swapping Gruyere with aged Parmesan or adding a bit of toasted pine nuts on top.

If leeks are unavailable, shallots can be a good substitute but cook them gently to avoid burning.

Reserve some pasta water as it helps to loosen the sauce without watering down the flavor.

FAQs

Can I use another type of cheese instead of Gruyere?

Yes, you can substitute Gruyere with other melting cheeses like Fontina, Emmental, or aged Parmesan for a slightly different but delicious flavor.

How do I clean leeks properly?

Slice leeks and then rinse them thoroughly in a bowl of cold water to remove any dirt or sand trapped between the layers. Drain and dry before cooking.
