How to Make Caramelized Leek and Mushroom Gruyere Pasta

Caramelize Leeks: In a large pan, heat olive oil and 2 tablespoons of butter over medium heat. Add sliced leeks, a pinch of salt, and granulated sugar. Cook until the leeks are golden and tender, about 20 minutes. Stir occasionally and add a splash of water if they begin to stick.
Cook Mushrooms: Once the leeks are beautifully caramelized, remove them from the pan. In the same pan, melt the remaining butter. Sauté the oyster mushrooms until they are browned and tender, about 8 minutes. Remember to season with salt and freshly ground black pepper.
Combine Ingredients: Bring back the caramelized leeks to the pan, then stir in minced garlic and sage. Cook for another minute until fragrant. Pour in the heavy cream, balsamic vinegar, and lemon zest, then simmer until the sauce thickens slightly, about 2-3 minutes.
Prepare Pasta: While the sauce is simmering, cook the fettuccine in a large pot of salted boiling water until al dente. Make sure to reserve 1 cup of the pasta water before you drain the fettuccine.
Mix and Serve: Toss the drained fettuccine into the sauce, adding some reserved pasta water to achieve your desired consistency. Stir in the Gruyere cheese and black pepper, mixing until everything is well coated. Serve hot, garnished with toasted pine nuts for an added crunch.

Optional: Drizzle some extra balsamic vinegar on top before serving for an extra burst of flavor.

Caramelized Leek and Mushroom Gruyere Pasta Recipe FAQs

How do I choose ripe leeks for this recipe?
Absolutely! When selecting leeks, look for those with vibrant green tops and firm, white shafts. Avoid any that show dark spots or wilting, as they may be past their prime. Fresh leeks should feel heavy for their size and have a mild, inviting aroma.

What’s the best way to store leftovers of this pasta?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Just make sure to allow them to cool down to room temperature first before sealing. When reheating, gentle heat is key—consider adding a splash of cream or reserved pasta water to maintain that rich, creamy texture.

Can I freeze Caramelized Leek and Mushroom Gruyere Pasta?
Yes, you can! To freeze this pasta, place it in an airtight, freezer-safe container. It will keep well for up to 2 months. I recommend freezing it before mixing in the cheese for optimal texture. Thaw overnight in the fridge before reheating on low heat, stirring in a bit of cream or pasta water for added creaminess.

What should I do if my leeks or mushrooms cook unevenly?
Very! If your leeks or mushrooms aren’t cooking evenly, it’s often due to overcrowding the pan. Be sure to cook them in batches if necessary, allowing enough space for steam to escape. For leeks, caramelizing evenly takes patience—keep the heat at medium to avoid burnt spots, adding a splash of water if they start to stick.

Are there any dietary considerations for this recipe?
Certainly! If you have allergies, take note that pine nuts can be substituted with walnuts or omitted altogether. For a dairy-free option, use all olive oil instead of butter and opt for a non-dairy cream substitute in the sauce. It’s always good to check ingredient labels to ensure there are no hidden allergens.

Can I make this pasta ahead of time?
Of course! You can prepare the sauce a day before and store it in the fridge. Just be sure to cook the pasta fresh on the day you’re serving it to maintain the best texture. To reheat the sauce, warm it gently over low heat while stirring frequently—add a little reserved pasta water or cream as needed to bring it back to that velvety consistency.
