Ingredients
Scale
- 12 ounces pasta (I love using pappardelle or fettuccine, but any wide noodle works)
- 2 large leeks (white and light green parts only), thinly sliced
- 8 ounces cremini or baby bella mushrooms, sliced
- 3 tablespoons unsalted butter
- 2 tablespoons olive oil
- 2 cloves garlic, minced
- 1 cup Gruyere cheese, shredded (substitute with fontina or mozzarella for a milder flavor)
- 1/2 cup heavy cream or half-and-half (for a lighter option, use whole milk)
- 1/4 cup dry white wine or vegetable broth (optional but adds great depth)
- Salt and freshly ground black pepper, to taste
- Fresh thyme leaves or chopped parsley, for garnish
- Grated Parmesan, for serving (optional but highly recommended)
Instructions
- Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Reserve about 1 cup of pasta water before draining.
- While pasta cooks, heat the butter and olive oil in a large skillet over medium heat. Add the sliced leeks and sauté slowly for about 8-10 minutes, stirring occasionally, until they’re soft and golden brown. This slow caramelization is key to bringing out their sweetness—trust me, it’s worth the patience.
- Add the sliced mushrooms to the skillet with the leeks. Continue cooking for another 6-8 minutes until the mushrooms release their moisture and start to brown. Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant.
- Pour in the white wine or vegetable broth, scraping the bottom of the pan to deglaze and lift all those flavorful bits. Let it simmer for 2-3 minutes until reduced by half.
- Lower the heat and stir in the heavy cream. Add the shredded Gruyere cheese gradually, stirring until melted and creamy. If the sauce seems too thick, add reserved pasta water a little at a time to reach your desired consistency.
- Toss the cooked pasta into the skillet, making sure every strand is coated with that luscious sauce. Season generously with salt and freshly ground black pepper to taste.
- Serve immediately, garnished with fresh thyme or parsley and a sprinkle of Parmesan if you like. This is the moment your kitchen starts to feel like home—the kind of meal that makes everyone pause and smile.
