Step‑by‑Step Instructions for Caramelized Leek and Mushroom Gruyere Pasta
Step 1: Cook Pasta
Bring a large pot of salted water to a rolling boil over high heat. Add your choice of pasta, cooking it until al dente, usually around 8-10 minutes depending on the type. Reserve half a cup of the starchy pasta water before draining the other half and set aside.
Step 2: Caramelize Leeks
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the sliced leeks along with a pinch of salt, stirring occasionally. Allow them to cook slowly for about 10-12 minutes, or until they’re beautifully golden and caramelized, giving off a sweet aroma.
Step 3: Sauté Mushrooms
Add 2 tablespoons of butter to the skillet with the caramelized leeks. Incorporate the sliced mushrooms and sauté for 5-7 minutes, stirring occasionally, until they are browned and tender. Make sure the mushrooms have enough space in the pan to sauté properly, enhancing their flavor.
Step 4: Combine Flavors
Stir in 2 cloves of minced garlic and 1 teaspoon of fresh thyme leaves to the skillet. Cook for an additional minute, just until the garlic becomes fragrant, blending beautifully with the earthy mushrooms and sweet leeks in your Caramelized Leek and Mushroom Gruyere Pasta.
Step 5: Create Sauce
Pour in 1 cup of vegetable broth and scrape up any flavorful bits from the bottom of the skillet. Allow the mixture to simmer for 3-4 minutes. Then, add in 1 cup of heavy cream and stir in the Gruyere cheese until it melts and creates a creamy sauce, adjusting the texture with reserved pasta water if needed.
Step 6: Finish Pasta
Finally, add the drained pasta to the skillet, tossing everything together until the pasta is evenly coated in the creamy Gruyere sauce. Adjust seasoning with salt, pepper, and a squeeze of lemon juice to brighten up the dish. Your Caramelized Leek and Mushroom Gruyere Pasta is ready to serve!

Make Ahead Options
Preparing your Caramelized Leek and Mushroom Gruyere Pasta in advance is a fantastic way to save time on busy weeknights! You can caramelize the leeks and sauté the mushrooms up to 3 days ahead and store them in an airtight container in the refrigerator. This allows the flavors to deepen while ensuring they’re just as delicious when combined with the pasta. When it’s time to serve, simply reheat these components in a skillet, add the cream and cheese, and toss with the cooked pasta until creamy. For optimal texture, save a bit of the reserved pasta water to adjust the sauce consistency just before serving. Enjoy a homemade meal with minimal effort!
