Ingredients
For the Pasta
- 2 tablespoons olive oil
- 3 tablespoons butter (divided)
- 3 medium leeks (tops removed, cut in half and thinly sliced)
- 1/2 teaspoon salt
- 1/2 teaspoon granulated sugar
- 1/3 cup apple juice
- 8 ounces oyster mushrooms
- 4 garlic cloves (minced)
- 2 sage leaves
- 3/4 cup heavy cream
- 1 tablespoon balsamic vinegar
- 1 teaspoon lemon zest
- 1 lb fettuccine
- 1 cup reserved pasta water
- 1/2 cup grated gruyere
- 1 teaspoon black pepper

How to Make Caramelized Leek and Mushroom Gruyere Pasta
Step 1: Sauté the Leeks
Heat 2 tablespoons of olive oil and 2 tablespoons of butter in a large sauté pan over medium heat. Add sliced leeks along with 1/2 teaspoon salt and 1/2 teaspoon sugar. Cook until the leeks turn golden brown and caramelized, which should take about 20 minutes. Stir occasionally to prevent sticking. If needed, add 1-2 tablespoons of water if the pan becomes too dry.
Step 2: Add Apple Juice
Once the leeks are caramelized, pour in the apple juice. Allow it to cook until reduced. Afterward, carefully remove the leeks from the pan and set them aside.
Step 3: Cook Mushrooms
In the same pan, melt another tablespoon of butter over medium heat. Spread out the oyster mushrooms in an even layer in the pan, ensuring they have space between them. Let them sit undisturbed until browned on one side (approximately 4 minutes). Flip them over, season with salt and pepper, and continue browning on the other side.
Step 4: Combine Ingredients
Next, add minced garlic and sage to the pan with mushrooms. Sauté for about one minute until fragrant. Then return the caramelized leeks back into the pan along with 3/4 cup of heavy cream, balsamic vinegar, and lemon zest. Bring everything to a gentle simmer while cooking until thickened (about 2-3 minutes). Adjust seasoning with additional salt and pepper as needed.
Step 5: Cook Fettuccine
While you’re preparing the sauce, cook fettuccine according to package instructions until al dente. Remember to reserve 1 cup of pasta water before draining.
Step 6: Mix Pasta with Sauce
Add the drained fettuccine directly into the sauce along with reserved pasta water (about 1 cup), grated gruyere cheese, and black pepper. Toss everything together gently until well combined. Let it simmer for an additional two minutes or until the cheese is melted completely.
Step 7: Serve
Portion out the pasta into four bowls and garnish each serving with toasted pine nuts for added crunch. Serve immediately while hot!

Common Mistakes to Avoid
Cooking can be tricky, especially when it comes to pasta dishes. Here are some common pitfalls to watch out for to ensure your Caramelized Leek and Mushroom Gruyere Pasta turns out perfectly.
- Overcooking the leeks: Caramelizing leeks requires patience. If you cook them too quickly on high heat, they won’t develop the rich flavor. Always use medium heat and stir occasionally for even cooking.
- Not reserving pasta water: Pasta water is essential for creating a smooth sauce. Forgetting to reserve it can lead to a dry dish. Always save at least one cup of the starchy water before draining your pasta.
- Skipping the seasoning: Proper seasoning is key to enhancing flavors. Taste your sauce before serving and adjust with salt and pepper as needed. A little seasoning can make a big difference!
- Forgetting to toast pine nuts: Toasting pine nuts brings out their flavor and adds crunch. Don’t skip this step; just a few minutes in a dry skillet can elevate your dish significantly.
- Using cold ingredients: Cold cream or cheese can cause the sauce to seize up. Make sure your heavy cream is at room temperature before adding it to the dish for a smoother texture.
