Recipe Origin

Gruyere pasta recipes are inspired by the rich, cheesy flavors of French and Swiss cuisine, combined with Italian pasta traditions. Caramelized leeks add a subtle sweetness, and mushrooms bring an earthy depth that makes the dish sophisticated yet comforting. The addition of sherry, balsamic, and lemon zest elevates the flavors without overpowering the pasta, creating a balanced, memorable dish.

Kitchen Tools You’ll Need

You’ll need a large pot for boiling pasta, a large skillet for caramelizing leeks and mushrooms, a wooden spoon or silicone spatula for stirring, a small bowl for mixing, a cheese grater for Gruyere, and a microplane or zester for the lemon.

(Note: The full ingredients list, including measurements, is provided in the recipe card directly below.)

Instructions

Preheat and Prep: Bring a large pot of salted water to a boil for the fettuccine. While the water heats, clean and slice the leeks, and prepare mushrooms.

Caramelize the Leeks: In a large skillet, heat olive oil and 1 tablespoon of butter over medium heat. Add sliced leeks, salt, and sugar. Cook, stirring occasionally, until the leeks are soft and golden brown, about 10-12 minutes. The sweet, fragrant aroma will fill your kitchen.

Cook the Mushrooms: Add the remaining butter to the skillet along with oyster mushrooms. Sauté until tender and slightly browned. Add minced garlic and sage leaves, cooking until fragrant.

Deglaze with Sherry: Pour in sherry wine, scraping up any browned bits from the bottom of the pan. Let it simmer for a few minutes until slightly reduced.

Add Cream and Balsamic: Stir in heavy cream and balsamic vinegar. Let the sauce simmer gently until slightly thickened. Add lemon zest for brightness. Taste and season with black pepper.

Cook the Pasta: While the sauce simmers, cook fettuccine according to package instructions until al dente. Reserve 1 cup of pasta water before draining.

Combine Pasta and Sauce: Add drained fettuccine to the skillet with the sauce. Toss gently, adding reserved pasta water a little at a time to achieve a silky, luscious coating. Sprinkle grated Gruyere over the pasta, tossing until melted and evenly distributed.

Serve and Garnish: Plate the pasta, then sprinkle with toasted pine nuts for crunch. Optionally, add fresh herbs like parsley or sage for an elegant touch. Serve immediately while warm and creamy.

How to Serve Caramelized Leek and Mushroom Gruyere Pasta

Fresh Salads: A crisp green salad with a light vinaigrette contrasts beautifully with the creamy pasta.
Crusty Bread: Serve with toasted bread or garlic baguette to soak up the rich sauce.
Vegetable Sides: Roasted or sautéed vegetables, like asparagus or zucchini, complement the earthy flavors.
Wine Pairing: A light white wine like Chardonnay or Sauvignon Blanc balances the richness of the cream and cheese.
As a Standalone: This dish is rich enough to enjoy on its own, with pine nuts adding a satisfying crunch.

Make-Ahead and Storage Tips

Prepare the sauce ahead of time and refrigerate. When ready to serve, reheat gently in a skillet, adding a splash of reserved pasta water to restore creaminess. Leftover pasta can be stored in an airtight container in the refrigerator for up to three days. Reheat gently to prevent the sauce from separating.

Variations to Try

Swap fettuccine for tagliatelle or pappardelle for a different texture. Add sautéed spinach or kale for extra greens. Use Parmesan instead of Gruyere if desired. Add a pinch of red pepper flakes for a subtle kick.

Additional Tips

Prep Ahead: Slice leeks and mushrooms ahead of time to save time during cooking.
Caramelization Tip: Be patient while caramelizing leeks—they develop deep, sweet flavor slowly.
Cheese Tip: Grate Gruyere fresh for better melting and flavor.
Storage Tips: Store leftovers in an airtight container and reheat gently.
Double the Batch: This recipe scales well for larger gatherings. Cook pasta and sauce in batches if necessary.
