This Caramelized Leek and Mushroom Gruyere Pasta packs amazing flavor with just a handful of basic ingredients. The mix of sweet caramelized leeks, down-to-earth mushrooms, and rich Gruyere cheese makes for a cozy meat-free meal that works any night of the week and really brings spring tastes to life.

What Makes This Dish Special

The pasta brings together rich, sweet and hearty flavors in one bowl. Leeks turn wonderfully sweet when caramelized, mushrooms add that deep earthy taste, and the Gruyere pulls everything together with its creamy, nutty touch. It's fancy enough for guests but simple enough for everyday dinners, making you feel like you're treating yourself without much fuss.

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

→ What other mushrooms can I use?
You can try cremini, button, chanterelle, or even mix several kinds. They’ll each add unique textures and flavors.
→ Can I prep this dish early?
Yep! Make the sauce ahead of time (follow steps 1-4). When you’re ready to eat, simply reheat and toss with freshly cooked pasta.
→ What’s the point of saving pasta water?
It’s full of starch! That starchy water helps make the sauce creamy and stick to the noodles. Plus, it’s useful if the sauce gets too thick.
→ Can I switch out gruyere cheese?
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.

Yield: 4 Servings (4 bowls)

Ingredients

01 2 sage leaves.
02 4 garlic cloves, finely chopped.
03 ½ cup grated gruyere cheese.
04 ¾ cup heavy cream.
05 1 lb fettuccine pasta.
06 ¼ cup pine nuts, toasted.
07 1 tablespoon balsamic vinegar.
08 1 teaspoon black pepper.
09 1 teaspoon lemon zest.
10 ⅓ cup sherry wine.
11 ½ teaspoon sugar.
12 ½ teaspoon salt.
13 3 medium leeks, halved and thinly sliced, with tops removed.
14 8 ounces oyster mushrooms.
15 3 tablespoons butter, split up.
16 2 tablespoons olive oil.
17 1 cup extra liquid from pasta after cooking.

Instructions

Step 01

Grab a large pan and heat some olive oil with a couple spoons of butter over medium heat. Toss in the leeks, sprinkle on the sugar and salt, and keep stirring every now and then for 20 minutes until golden brown. If it dries out, splash in a bit of water to fix it.

Step 02

Pour in the sherry and let it bubble until it’s almost gone. Scoop the leeks out of the pan and set those aside.

Step 03

Melt the rest of the butter in the same pan. Spread the mushrooms out in a single layer and leave them alone for a few minutes so one side gets nice and brown. Flip them over and do the same on the other side, then season with some salt and pepper.

Step 04

Add chopped garlic and sage leaves to the pan. Stir for a minute, then toss the leeks back in, along with the cream, balsamic vinegar, and lemon zest. Let it simmer until it thickens, which takes just a couple of minutes. Adjust the seasoning if needed.

Step 05

While that’s happening, cook the fettuccine till it’s just right (al dente). Keep a cup of the pasta’s cooking water before draining it.

Step 06

Take the sauce and toss it with the cooked fettuccine, pasta water, gruyere, and black pepper. Simmer for a quick 2 minutes until everything is melty and the noodles are coated completely. Taste and tweak the seasoning.

Step 07

Scoop the pasta into four bowls and sprinkle pine nuts on top. Enjoy it on the spot while still warm.

Notes

  1. Feel free to swap the oyster mushrooms for cremini, button, mixed, or chanterelle mushrooms.
  2. You can prep the sauce in advance (steps 1 through 4) and just reheat when you're ready to cook the noodles.
