Step‑by‑Step Instructions for Creamy Mushroom Gruyere Pasta
Step 1: Cook the Pasta
Bring a large pot of salted water to a rolling boil. Add 12 oz of pasta and cook until al dente, about 8-10 minutes. Stir occasionally to prevent sticking. Once cooked, reserve ½ cup of the pasta water, then drain the pasta and set it aside, letting the steam escape while you prepare the flavorful sauce.
Step 2: Caramelize the Leeks
In a large skillet, combine 2 tablespoons of unsalted butter and 2 tablespoons of olive oil over medium heat. Once melted, add the sliced leeks, cooking for 12-15 minutes. Stir frequently, allowing them to gradually turn golden brown and caramelized. You’ll know they’re ready when the leeks are soft and sweet, filling your kitchen with a delightful aroma.
Step 3: Sauté Mushrooms and Garlic
Add 8 oz of sliced mushrooms to the caramelized leeks in the skillet, stirring well. Cook for 6-8 minutes until the mushrooms are softened and begin to brown. Then, sprinkle in 2 minced garlic cloves, cooking for an additional minute until fragrant. The mixture should be colorful and inviting, with the mushrooms absorbing the flavors of the leeks.
Step 4: Create the Cheese Sauce
Lower the heat to medium-low, then pour in ½ cup of heavy cream. Stir well to combine, allowing it to gently warm. Gradually add 1 ½ cups of shredded Gruyere cheese, mixing until the cheese melts completely into a creamy sauce. This decadent sauce should be smooth and luscious, ready to envelop the pasta.
Step 5: Combine Pasta and Sauce
Add the cooked pasta to the skillet with the cheese sauce, tossing gently to coat all the noodles. If the sauce appears too thick, slowly incorporate the reserved pasta water until you achieve the desired creaminess. Season generously with salt and freshly ground black pepper as you stir in the remaining Gruyere cheese, enriching the flavor of your Creamy Mushroom Gruyere Pasta.
Step 6: Serve and Garnish
Serve the creamy pasta immediately, garnishing with freshly chopped parsley for a pop of color and freshness. This final touch elevates your dish, making it visually appealing and even more delicious. Pair your Creamy Mushroom Gruyere Pasta with a side salad or garlic bread for a complete cozy dinner experience.
