Step‑by‑Step Instructions for Creamy Mushroom Gruyere Pasta
Step 1: Cook the Pasta
Begin by bringing a large pot of salted water to a rolling boil. Add 12 ounces of your chosen pasta and cook according to package instructions until al dente, about 8-10 minutes. As it cooks, reserve ½ cup of the pasta water for later use, then drain the pasta and set it aside, letting the steam escape to prevent sticking.
Step 2: Caramelize the Leeks
In a large skillet, melt 2 tablespoons of unsalted butter with 2 tablespoons of olive oil over medium heat. Once the butter has fully melted and the mixture is shimmering, add the sliced leeks. Sauté them for about 12-15 minutes, stirring occasionally, until they become golden brown and caramelized, releasing their sweet aroma.
Step 3: Add the Mushrooms
Once the leeks have caramelized, stir in 8 ounces of sliced mushrooms. Cook for an additional 6-8 minutes, allowing the mushrooms to soften and brown. As they cook, their earthy flavor will meld beautifully with the leeks. Add 2 minced garlic cloves in the last minute, sautéing until fragrant, ensuring not to burn the garlic.
Step 4: Make the Creamy Sauce
Reduce the heat to low, then pour in ½ cup of heavy cream and half of the 1½ cups of shredded Gruyere cheese. Stir continuously until the cheese fully melts and the sauce becomes smooth and creamy. This rich sauce will embrace the leeks and mushrooms, transforming the dish into a comforting creamy mushroom Gruyere pasta.
Step 5: Combine Pasta and Sauce
Gently fold the cooked pasta into the creamy sauce, ensuring each strand is coated in the luscious mixture. If the sauce appears too thick, gradually add a bit of the reserved pasta water until you’ve achieved the desired consistency. Mix in the remaining Gruyere cheese, stirring until well incorporated.
Step 6: Season and Serve
Taste your creamy mushroom Gruyere pasta and season with salt and black pepper to your liking. Once everything is well mixed and heated through, serve immediately, garnishing with freshly chopped parsley if desired. The creamy texture and layers of flavor will surely delight your taste buds!
