How to Make Caramelized Leek and Mushroom Gruyere Pasta
Step 1: Sauté the Leeks
Heat 2 tablespoons olive oil and 2 tablespoons butter in a large sauté pan over medium heat. Add sliced leeks and season with 1/2 teaspoon salt and 1/2 teaspoon sugar. Cook until golden and caramelized, about 20 minutes, stirring occasionally. If the pan gets too dry, add 1–2 tablespoons of water.
Step 2: Prepare the Liquid Base
Add apple juice to the pan with leeks. Continue to cook until the juice has reduced. Remove leeks from the pan and set them aside.
Step 3: Cook the Mushrooms
In the same pan, melt another tablespoon of butter. Spread oyster mushrooms in an even layer, giving them plenty of space in between. Let them sit until browned, about 4 minutes. Flip and continue to brown on the other side. Season with salt and pepper.
Step 4: Combine Flavors
Add minced garlic and sage to the mushrooms; sauté for 1 minute until fragrant. Return leeks to the pan along with heavy cream, balsamic vinegar, and lemon zest. Bring to a simmer and cook until thickened, about 2–3 minutes. Season with salt and pepper as needed.
Step 5: Cook Fettuccine
Meanwhile, cook fettuccine in salted water until al dente according to package instructions. Reserve 1 cup of cooking water before draining.
Step 6: Toss Everything Together
Add cooked fettuccine directly into the sauce along with reserved pasta water, grated Gruyere cheese, and black pepper. Toss everything to coat evenly. Simmer for an additional 2 minutes or until cheese melts into the sauce.
Step 7: Serve

Common Mistakes to Avoid
When making Caramelized Leek and Mushroom Gruyere Pasta, it’s easy to overlook some key steps. Here are common mistakes and how to avoid them.
- Not caramelizing the leeks properly: Leeks need enough time to develop their sweetness. Cook them low and slow for about 20 minutes until they turn golden brown.
- Skipping the pasta water: Reserving pasta water is crucial for creating a creamy sauce. This starchy water helps bind the sauce to the pasta.
- Overcooking the mushrooms: Mushrooms should be browned but not mushy. Allow them to sit in the pan without stirring too much for perfect browning.
- Using the wrong cheese: Gruyere adds a unique flavor, but if you can’t find it, try other melting cheeses like fontina or mozzarella for a similar effect.
- Ignoring seasoning: Taste as you go! Adjust salt and pepper throughout cooking to enhance flavors and ensure a well-seasoned dish.
