Caramelized Leek and Mushroom Gruyere Pasta Ingredients
- 12 oz (340 g) pasta (fettuccine, linguine, or pappardelle work well)
- 2 tablespoons olive oil
- 2 large leeks, white and light green parts only, thinly sliced (about 2 ½ cups)
- 10 oz (285 g) cremini or baby bella mushrooms, sliced
- 2 tablespoons unsalted butter
- 4 cloves garlic, minced
- ½ cup (120 ml) dry white wine
- ¾ cup (180 ml) heavy cream
- 1 cup (3 oz/85 g) Gruyere cheese, freshly grated
- ½ teaspoon salt, plus more for pasta water
- ¼ teaspoon freshly ground black pepper
- ¼ teaspoon crushed red pepper flakes (optional)
- 2 tablespoons chopped fresh parsley
- Zest of 1 lemon (optional, for brightness)
How to Make Caramelized Leek and Mushroom Gruyere Pasta
Step 1: Prep the Ingredients
Wash and thinly slice your leeks—be sure to clean thoroughly as dirt can hide between layers. Slice mushrooms and grate the Gruyere cheese.
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente (usually 10-12 minutes). Reserve ¾ cup of pasta water and drain the rest.
Step 3: Caramelize the Leeks and Sauté the Mushrooms
While the pasta cooks, heat olive oil in a large skillet over medium-low heat. Add leeks and a pinch of salt. Cook, stirring frequently, for 8-10 minutes until leeks are very soft and golden. Increase the heat to medium. Add mushrooms and cook for 6-8 minutes until browned and their moisture has evaporated.
Step 4: Build the Sauce
Add butter and garlic to the skillet, stirring for 1-2 minutes until fragrant. Pour in the white wine, scraping up brown bits, and simmer for 2-3 minutes until reduced by half. Reduce heat to low, stir in cream, salt, black pepper, and (if using) red pepper flakes. Cook for 2 minutes to thicken.
Step 5: Finish and Serve
Toss the drained pasta into the skillet. Add Gruyere, a handful at a time, stirring gently until melted and creamy. If needed, loosen the sauce with reserved pasta water until it slickly coats the noodles.
Sprinkle with parsley and lemon zest. Serve hot, optionally with extra Gruyere and cracked black pepper.
Notes: Tips for Caramelized Leek and Mushroom Gruyere Pasta Success
- Gruyere melts best when freshly grated—pre-shredded cheese may be coated with anti-caking agents and won't get as smooth. Learn more about cheese melting properties here.
- If leeks start to brown too quickly, lower the heat and add a splash of water.
- This dish can go vegetarian or gluten-free with the right pasta choices (see pasta cooking guide).
Variations: Twist on Caramelized Leek and Mushroom Gruyere Pasta
- Truffle Edition: Drizzle with truffle oil before serving for extra earthy decadence.
- Protein Boost: Add sautéed chicken, prosciutto, or chickpeas for extra staying power.
- Greener Version: Stir in a big handful of baby spinach or peas right at the end for color and nutrients.

Storage Instructions for Leftover Caramelized Leek and Mushroom Gruyere Pasta
