Sometimes you just need pasta. A good cheesy one. This dish combines caramelized leeks with creamy Gruyère. Add some sautéed oyster mushrooms for an added buttery chew and I’m in heaven. Don’t skip the cream, it truly makes this dish.
Ingredients
2 tablespoons olive oil
3 tablespoons butter divided
3 medium leeks tops removed, cut in half and thinly sliced
½ teaspoon salt
½ teaspoon granulated sugar
⅓ cup sherry wine
8 ounces oyster mushrooms
4 garlic cloves minced
2 sage leaves
¾ cup heavy cream
1 tablespoon balsamic vinegar
1 teaspoon lemon zest
1 lb fettuccine
1 cup reserved pasta water
½ cup grated gruyere
1 teaspoon black pepper
¼ cup toasted pine nuts
Instructions
Heat 2 tablespoons olive oil and 2 tablespoons butter in a large saute pan over medium heat. Add sliced leeks and season with ½ teaspoon salt and ½ teaspoon sugar. Cook until golden and caramelized, about 20 minutes, stirring occasionally. If the pan gets too dry, add 1-2 tablespoons of water.
Add sherry and continue to cook until the wine has reduced. Remove leeks from the pan and set them aside.
In the same pan, melt another tablespoon of butter. Spread 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.
Add minced garlic and sage and saute for 1 minute. Add back leeks along with ¾ cupheavy cream, balsamic vinegar, and lemon zest. Bring to a simmer and continue to cook until thickened, about 2-3 minutes. Season the sauce with salt and pepper.
Meanwhile, cook fettuccine until al dente. Reserve 1 cup of the cooking pasta water.
Add fettuccine, 1 cup reserved pasta water, gruyere, and black pepper to the sauce, tossing to coat. Simmer for 2 minutes or until the cheese is melted and the pasta is well coated. Give a final seasoning with salt and pepper.
Portion pasta into 4 bowls and garnish with toasted pine nuts. Serve immediately.
Notes
Although I used oyster mushrooms, you can substitute them with another type of mushroom such as cremini, button, chanterelle, or a mixture of mushrooms.
If preparing the dish ahead of time, make the sauce following steps 1-4. Reheat it when ready to toss with the pasta.
