How to Make Caramelized Leek and Mushroom Gruyere Pasta
Step 1: Caramelize the Leeks
Heat 2 tablespoons of olive oil and 2 tablespoons of butter in a large saute pan over medium heat. Add the sliced leeks along with 1/2 teaspoon of salt and 1/2 teaspoon of sugar. Cooking these until golden and caramelized takes about 20 minutes. This step is crucial because it brings out their natural sweetness, making your sauce incredibly flavorful. If your pan gets too dry during cooking, don’t hesitate to add a tablespoon or two of water.
Step 2: Deglaze the Pan
Once your leeks are beautifully caramelized, add in your apple juice. Cook until the liquid has reduced slightly. This adds depth to your sauce while also lifting those delicious bits stuck at the bottom of the pan. Set those lovely leeks aside while we work on our mushrooms.
Step 3: Sauté the Mushrooms
In the same pan, melt another tablespoon of butter. Spread out your oyster mushrooms evenly so they have space to brown nicely—this helps develop their flavor. Let them sit without stirring for about 4 minutes before flipping them over to brown on the other side. Season with salt and pepper once they’re golden.
Step 4: Build Your Sauce
Add minced garlic and sage into the pan with the mushrooms and sauté for about one minute until fragrant. Then return those caramelized leeks back into the mix along with heavy cream, balsamic vinegar, and lemon zest. Bringing this mixture to a simmer thickens your sauce beautifully—about 2-3 minutes should do it! Don’t forget to season well with salt and pepper.
Step 5: Cook Your Pasta
Meanwhile, cook your fettuccine according to package instructions until al dente. Remember to reserve one cup of that starchy pasta water—it’s liquid gold for helping our sauce adhere perfectly!
Step 6: Combine Everything
Now it’s time for some magic! Add your cooked fettuccine directly into that luscious sauce along with one cup of reserved pasta water, grated gruyere cheese, and black pepper. Toss everything together gently until each strand of pasta is coated in that creamy goodness—cook it all together on low heat for another two minutes to melt that cheese perfectly.
Step 7: Serve It Up
Finally, portion out your Caramelized Leek and Mushroom Gruyere Pasta into bowls and sprinkle with toasted pine nuts for an extra crunch! Serve immediately while it’s warm—the best way to enjoy this comforting dish.
I hope you love making this recipe as much as I do! Bon appétit!
Pro Tips for Making Caramelized Leek and Mushroom Gruyere Pasta

-
Use fresh leeks: Fresh leeks not only taste better, but they also caramelize beautifully, enhancing the sweetness of the dish. Look for firm, vibrant green tops.

Don’t rush the caramelization: Allowing the leeks to cook slowly will bring out their natural sweetness. Stir them occasionally, but resist the urge to turn up the heat; patience is key!
-
Reserve pasta water: The starchy pasta water is a fantastic way to adjust the sauce’s consistency. It helps bind everything together and ensures your pasta is creamy without being too heavy.
