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.
Storage
Store leftover pasta in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave, adding a splash of cream or broth to restore creaminess if needed.
