What You'll Need for Gruyere Pasta
- Pasta: 1 pound pappardelle or fettuccine.
- Leeks: 3 large, washed and cut into thin slices (just white and light green sections).
- Mushrooms: 1 pound various mushrooms, sliced up.
- Butter: 4 tablespoons to cook the veggies.
- Olive Oil: 2 tablespoons for cooking.
- Gruyere Cheese: 2 cups freshly shredded.
- Heavy Cream: 1 cup.
- White Wine: 1/2 cup to scrape up tasty bits.
- Fresh Thyme: 2 teaspoons, diced.
- Salt and Pepper: As much as you like.
- Fresh Parsley: Chopped to sprinkle on top.
Steps for Making Leek and Mushroom Pasta
- Get Those Leeks Going
- Mix butter and olive oil in a big pan over medium heat. Toss in your leek slices and let them cook slowly for 20-25 minutes, giving them a stir now and then until they turn golden and sweet.
- Tackle the Mushrooms
- Throw mushrooms in with those caramelized leeks. Let them cook until they're golden brown and the liquid dries up, around 8-10 minutes. Sprinkle with thyme, salt, and pepper.
- Make Your Sauce Base
- Add the white wine and scrape up all the tasty brown bits. After the wine cooks down, pour in the heavy cream and let it bubble until it thickens a bit.
- Sort Out the Pasta
- Boil pasta in salty water until it's got a little bite left. Save a cup of that starchy water before draining. Mix pasta into your sauce, adding some of that saved water if things look too thick.
- Put It All Together
- Mix in your shredded Gruyere until everything gets melty and smooth. Scatter fresh parsley on top and maybe some extra cheese if you're feeling fancy.

Keeping It Fresh
You can get the sauce ready a day early and warm it up gently before mixing with fresh pasta. Leftovers will keep in the fridge for up to 3 days in a sealed container. When reheating, add a splash of heavy cream to bring back that smooth, creamy texture.
Frequently Asked Questions

- Absolutely! Try fontina, raclette, or even a mild white cheddar. The flavor will change, but it’ll still turn out creamy and tasty.
- → Why do we caramelize leeks?
- Caramelizing leeks brings out their sweetness and adds another layer of flavor. The pinch of sugar speeds this up and balances the savory parts of the dish.
