• Garlic – 2 cloves, minced; enhances aroma and overall flavor.
• Gruyere Cheese – 1 ½ cups (150 g), shredded; key for a luscious, creamy sauce. Substitution: Fontina or Swiss cheese for different flavors.
• Heavy Cream – ½ cup (120 ml); creates a velvety sauce texture.
• Unsalted Butter – 2 tablespoons; aids in caramelization without added salt.

Step‑by‑Step Instructions for Creamy Mushroom Gruyere Pasta
Step 1: Cook the Pasta
Fill a large pot with water, add a generous pinch of salt, and bring it to a rolling boil over high heat. Once boiling, add 12 oz of pasta and cook according to package instructions until al dente, which typically takes about 8–10 minutes. Reserve ½ cup of the starchy pasta water before draining and set the pasta aside.
Step 2: Caramelize the Leeks
In a large skillet, melt 2 tablespoons of unsalted butter along with 2 tablespoons of olive oil over medium heat. Add the sliced leeks and sauté for 12–15 minutes. Stir frequently until they are a golden brown, fragrant, and beautifully caramelized, which will add a sweet depth to your Creamy Mushroom Gruyere Pasta.
Step 3: Sauté the Mushrooms and Garlic
Once the leeks are caramelized, add 8 oz of sliced mushrooms to the skillet. Sauté the mushrooms for 6–8 minutes until they are soft and slightly browned. Then, toss in 2 minced garlic cloves and keep cooking for 1 more minute until the garlic is fragrant, infusing the mixture with savory aromas.
Step 4: Create the Cheese Sauce
Lower the heat to a gentle simmer, and pour in ½ cup of heavy cream. Gradually add in half of the shredded Gruyere cheese, stirring continuously until the cheese melts and the sauce becomes creamy and smooth, approximately 3–5 minutes. This decadent cheese sauce will envelop the pasta perfectly later.
Step 5: Combine Pasta and Sauce
Carefully add the drained pasta into the skillet with the cheese sauce. Toss everything together thoroughly to ensure the pasta is coated in the creamy goodness. If the sauce is too thick, gradually stir in the reserved pasta water until you reach your desired consistency. Mix in the remaining Gruyere cheese, then season with salt and freshly ground black pepper to taste.
Step 6: Serve and Garnish
Plate the Creamy Mushroom Gruyere Pasta immediately, letting the inviting aroma fill your kitchen. If desired, sprinkle with chopped fresh parsley for a pop of color and brightness. Enjoy this comforting dish that transports you straight to culinary heaven!
