• Extra virgin olive oil – 2 tbsp to sauté leeks and add depth of flavor.
• Garlic – 3 cloves, minced, for aromatic warmth that complements the leeks.
For the Creamy Mixture
• Heavy cream – 1 cup creates a luscious, rich sauce that binds the dish together.

How to Make Caramelized Leek Pasta
-
Clean and prep: Wash the leeks thoroughly to remove any grit, then slice them thinly. Mince the garlic cloves to infuse that wonderful aroma in the dish.
-
Boil pasta: Bring a large pot of salted water to a boil. Add the fettuccine and cook according to package instructions, usually until al dente. Don’t forget to reserve 1 cup of pasta water before draining.
-
Sauté leeks: In a skillet over medium heat, drizzle in the olive oil and sauté the sliced leeks. Cook until they turn golden brown, which should take about 10-15 minutes. Stir occasionally to ensure even caramelization.
-
Add garlic: Once the leeks are beautifully caramelized, toss in the minced garlic. Sauté for an additional minute until the garlic is fragrant and starts to soften.
-
Make it creamy: Pour in the heavy cream and allow it to simmer for about 5 minutes. This will thicken the sauce slightly. If it’s too thick, adjust the consistency with the reserved pasta water.
-
Combine and serve: Gently mix the cooked pasta with the leek sauce in the skillet. Toss everything together well, then stir in the grated Parmesan cheese. Season with salt and pepper to taste, and enjoy!
Optional: For an extra touch, sprinkle with fresh parsley before serving.

Chef's Helpful Tips
- When preparing your Caramelized Leek Pasta, make sure to clean the leeks thoroughly, as dirt can hide between the layers.

- To enhance the flavor, consider adding a splash of white wine to the pan after sautéing the leeks and garlic, letting it reduce before adding the cream.
- Always taste and adjust the seasoning at the end, as the Parmesan will add saltiness to the dish that may require less additional salt.
