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 over high heat. Add 12 ounces of fettuccine or linguine and cook until al dente, about 8 to 10 minutes. Once cooked, reserve ½ cup of pasta water for later use, then drain the pasta and set it aside in a large bowl.
Step 2: Caramelize the Leeks
In a large skillet, heat 2 tablespoons of unsalted butter and 2 tablespoons of olive oil over medium heat. Once the butter melts, add the sliced leeks and cook for 12 to 15 minutes, stirring occasionally. You’ll know they’re ready when the leeks turn golden brown and caramelized, filling your kitchen with a sweet aroma.
Step 3: Sauté the Mushrooms and Garlic
Next, stir in the sliced mushrooms (8 ounces of cremini or button) into the skillet with the leeks. Sauté for another 6 to 8 minutes until the mushrooms are tender and have released their moisture. Add the minced garlic and cook for an additional minute until fragrant, bringing together the flavors of your creamy mushroom Gruyere pasta.
Step 4: Create the Cheese Sauce
Reduce the heat to low and pour in ½ cup of heavy cream, stirring to combine with the leeks and mushrooms. Gradually add ¾ cup of the shredded Gruyere cheese, mixing continuously until everything is melted and creamy. This luscious cheese sauce will envelop the pasta beautifully.
Step 5: Combine Pasta and Sauce
Add the drained pasta to the skillet, tossing it gently into the sauce. If the mixture seems too thick, pour in some of the reserved pasta water a little at a time to reach your desired consistency. Mix in the remaining Gruyere cheese and season with salt and freshly ground black pepper, enhancing the flavor of your creamy mushroom Gruyere pasta.
Step 6: Serve and Garnish
Serve the creamy mushroom Gruyere pasta immediately, garnishing each plate with freshly chopped parsley for a pop of color and flavor. This dish pairs perfectly with a simple side salad or warm, crusty bread to soak up the delicious sauce. Enjoy your comforting meal!
