Step‑by‑Step Instructions for Caramelized Leek and Mushroom Gruyere Pasta
Step 1: Boil the Pasta
Begin by bringing a large pot of salted water to a rolling boil over high heat. Add your choice of pasta, preferably tagliatelle or fettuccine, and cook until al dente, about 8-10 minutes. Reserve half a cup of the pasta water before draining the rest in a colander, allowing the strands to sit and remain warm as you prepare the sauce.
Step 2: Caramelize the Leeks
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the sliced leeks along with a pinch of salt, and stir to coat. Sauté for 10-12 minutes, stirring occasionally, until the leeks are soft and golden brown. Their sweet aroma will fill your kitchen, setting the stage for the delightful Caramelized Leek and Mushroom Gruyere Pasta.
Step 3: Sauté the Mushrooms
Add 2 tablespoons of butter and the sliced mushrooms to the skillet with the leeks. Cook, stirring frequently, for about 5-7 minutes until the mushrooms are browned and their moisture has evaporated. Then, add minced garlic and fresh thyme, cooking for an additional 1-2 minutes until fragrant, beautifully enhancing the earthy tones of the dish.
Step 4: Create the Sauce
Pour in 1 cup of vegetable broth into the skillet, scraping the bottom with a wooden spoon to deglaze and incorporate all those delicious browned bits. Allow the mixture to simmer gently for 2-3 minutes. Then, lower the heat and stir in the heavy cream, letting the sauce thicken slightly as it simmers on low heat for about 3-5 minutes, enveloping the leeks and mushrooms in creamy goodness.
Step 5: Melt the Gruyere
Gradually stir in 1 cup of shredded Gruyere cheese into the sauce, mixing until melted and smooth. If the sauce is too thick, add a bit of the reserved pasta water to achieve your desired consistency. Season the creamy mixture generously with salt, pepper, and a splash of lemon juice to enhance the flavors of your Caramelized Leek and Mushroom Gruyere Pasta.
Step 6: Combine and Serve
Toss the drained pasta into the skillet with the sauce, gently mixing until all the strands are well-coated. Ensure every bite gets a taste of that rich, creamy sauce. Serve immediately, garnished with additional thyme or cheese if desired, and savor the comforting flavors of your homemade Caramelized Leek and Mushroom Gruyere Pasta!

How to Store and Freeze Caramelized Leek and Mushroom Gruyere Pasta
Refrigerator: Store leftovers in an airtight container for up to 3 days. Gently reheat on the stove over low heat, adding a splash of cream or reserved pasta water to restore creaminess.

Make-Ahead: Prepare the sauce in advance and store it in the fridge. Cook the pasta fresh when ready to serve for the best results.
