Creamy Leek Mushroom Gruyere Pasta

This caramelized leek and mushroom Gruyere pasta is a comforting dish that feels special but comes together easily on busy evenings. The creamy sauce with nutty cheese and tender vegetables makes it perfect for a cozy dinner with minimal fuss.

I often make this after a long day when I want something rich but not complicated. It quickly became a staple in my weeknight rotation because it feels indulgent but cooks up fast.

Ingredients

• 12 ounces pasta (fettuccine or linguine): which holds the creamy sauce beautifully and cooks evenly
• 2 tablespoons olive oil: to provide a flavorful cooking base and help caramelize vegetables
• 2 medium leeks, thinly sliced (white and light green parts): for their sweet onion flavor and soft texture when caramelized—look for firm stalks with fresh green tops
• 8 ounces cremini mushrooms, sliced: offer earthiness and meaty texture that pairs well with cheese—choose mushrooms without dark spots or sliminess
• 3 cloves garlic, minced: adding bright aromatic depth to the sauce
• 1/2 cup dry white cooking broth or vegetable stock: to deglaze the pan and add savoriness without heaviness—choose a broth low in sodium for better control
• 1/2 cup heavy cream: to create a rich, silky sauce that carries the Gruyere wonderfully—use fresh cream with at least 36 percent fat
• 1 cup shredded Gruyere cheese: brings nutty, mellow flavor and smooth melting qualities—buy from the cheese counter if possible for freshness
• 1/4 teaspoon freshly ground black pepper: for gentle spice and balance
• Salt: to taste for seasoning and enhancing all flavors
• 1/4 cup chopped fresh parsley: optional for a vibrant fresh finish and color

Instructions

Build The Pasta base:

Cook pasta in plenty of salted water until al dente, following the package directions carefully. Reserve half a cup of the pasta water before draining. This starchy water will help adjust your sauce consistency later.

Caramelize The Leeks:

Heat olive oil in a large skillet over medium heat. Add the sliced leeks and cook, stirring occasionally for 6 to 8 minutes. Your goal is to get them soft and golden which unlocks their sweetness and creates the flavor foundation.

Cook The Mushrooms:

Add the sliced cremini mushrooms to the skillet. Continue cooking for another 5 to 7 minutes until the mushrooms have softened and developed a slight brown color. This adds complexity and earthiness to the dish.

Add Garlic And Deglaze:

Stir in the minced garlic and cook briefly for about 1 minute until fragrant but not burned. Pour in the white cooking broth or stock while scraping the bottom of the pan with your spatula to lift up any browned bits stuck to the skillet. Let this simmer for 2 minutes which intensifies flavor.

Create The Creamy Sauce:

Reduce heat to low and stir in the heavy cream. Allow the mixture to gently simmer for 3 to 4 minutes until it thickens slightly. This warm cream base will blend beautifully with the cheese.

Melt In The Gruyere:

Gradually add the shredded Gruyere cheese, stirring constantly as it melts smoothly into the sauce. Season with salt and freshly ground black pepper to your taste.

Finish And Toss:

Add the cooked pasta to the skillet and toss everything together thoroughly. Slowly stir in the reserved pasta water by the tablespoon to loosen the sauce if it feels too thick. This gives your dish just the right creamy coating.

Garnish And Serve:

Sprinkle chopped fresh parsley over the finished pasta for a pop of color and a touch of herbal brightness. Serve immediately for the best texture and flavor.

Gruyere is my favorite part of this recipe because it melts perfectly and balances the sweetness of caramelized leeks. This dish always reminds me of cozy nights at home when I want something special but quick. I learned that taking the time with caramelizing the leeks really lifts the dish from everyday to something memorable.

Storage Tips

Store any leftovers in an airtight container refrigerated for up to three days. Reheat gently on the stove adding a splash of milk or broth to refresh the sauce without breaking its creaminess. Avoid microwaving for best texture.

Ingredient Swaps

Try half-and-half instead of heavy cream for a lighter sauce that still has some richness. Parmesan or Fontina can replace Gruyere though the flavor will be less complex. For a vegan version, use cashew cream and nutritional yeast but expect a different texture.

Serving Ideas

Pair this pasta with a simple green salad dressed with lemon vinaigrette to cut through the richness. Crusty bread is perfect for mopping up any leftover sauce. A glass of dry white wine complements the mushroom and cheese flavors nicely.

This recipe brings out the best in simple ingredients with layered flavors. It’s sure to comfort and satisfy every time you make it.
