- 1/2 teaspoon salt
- 1/2 teaspoon granulated sugar

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 the sliced leeks along with 1/2 teaspoon salt and 1/2 teaspoon sugar. Cook until they are golden and caramelized, about 20 minutes, stirring occasionally. If the pan becomes too dry, add 1-2 tablespoons of water to keep them from burning.
Step 2: Add Apple Juice
Once the leeks are caramelized, pour in the apple juice grape juice. Continue cooking until it reduces down. Remove the leeks from the pan and set them aside.
Step 3: Brown the Mushrooms
In the same pan, melt another tablespoon of butter. Spread out the oyster mushrooms in an even layer, allowing space between them. Let them cook untouched until browned on one side, about 4 minutes. Flip them over to brown the other side and season with salt and pepper.
Step 4: Combine Ingredients
Add minced garlic and sage to the mushrooms, sautéing for about 1 minute until fragrant. Return the caramelized leeks to the pan along with 3/4 cup of heavy cream, balsamic vinegar, and lemon zest. Bring this mixture to a simmer, allowing it to thicken for about 2–3 minutes while seasoning with additional salt and pepper as desired.
Step 5: Cook Fettuccine
While preparing the sauce, cook your fettuccine in a pot of boiling salted water until al dente. Remember to reserve 1 cup of cooking water before draining.
Step 6: Combine Pasta with Sauce
Add cooked fettuccine directly into the sauce along with 1 cup of reserved pasta water, grated gruyere cheese, and black pepper. Toss everything together until well coated; let it simmer for an additional 2 minutes or until cheese melts thoroughly.

- Underseasoning the Sauce: Skipping salt or pepper can result in bland flavors. Taste and adjust seasoning at every stage of cooking for a well-balanced dish.
