What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver big flavor without the fuss. Here’s what you’ll need:

Pasta: 12 oz of your favorite variety (I love using linguine or fettuccine for this recipe).
Leeks: 2 large leeks, trimmed, halved, and sliced thinly (white and light green parts only).
Mushrooms: 8 oz cremini or button mushrooms, cleaned and sliced.
Gruyere Cheese: 1 ½ cups shredded Gruyere (adds creaminess and nutty flavor).
Garlic: 2 cloves, minced.
Olive Oil: 2 tbsp for sautéing.
Unsalted Butter: 2 tbsp for caramelizing the leeks.
White Wine: ¼ cup (optional, for deglazing and added depth).
Heavy Cream: ½ cup to create a luscious sauce.
Salt and Pepper: To taste.
Fresh Thyme: 1 tsp for garnish (optional).

For gluten-free, simply swap the pasta with your favorite GF version. And if you prefer vegetarian, skip the wine or use a veggie-friendly substitute. These ingredients come together to create a harmony of flavors that you’ll savor with every bite.

Equipment Needed

You don’t need any fancy gadgets to make this recipe. Here’s what you’ll want to have on hand:

Large Pot: For boiling the pasta.
Large Skillet: For caramelizing the leeks and sautéing the mushrooms.
Wooden Spoon: Perfect for stirring without damaging your cookware.
Cheese Grater: To shred Gruyere cheese (or buy pre-shredded to save time).
Colander: To drain the pasta.

While a non-stick skillet works fine, I’ve found that a stainless steel pan does a better job at evenly caramelizing the leeks. If you’re working with limited tools, a basic sauté pan will still deliver delicious results.

Preparation Method

Cook the Pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente. Drain and set aside, reserving ½ cup of the pasta water.
Caramelize the Leeks: Heat the butter in a large skillet over medium heat. Add the sliced leeks and sauté for 8-10 minutes, stirring occasionally, until golden and caramelized. Be patient—it’s worth it!
Sauté the Mushrooms: Push the leeks to one side of the skillet and add the olive oil. Toss in the mushrooms and garlic, cooking for 5-7 minutes until browned and tender. Mix everything together.
Deglaze with Wine: (Optional) Pour in the white wine and scrape any browned bits from the bottom of the pan. Let it simmer for 2-3 minutes until reduced.
Create the Sauce: Lower the heat and stir in the heavy cream and reserved pasta water. Sprinkle in the Gruyere cheese, stirring until melted and creamy. Season with salt and pepper to taste.
Toss the Pasta: Add the cooked pasta to the skillet and toss to coat evenly in the sauce. Cook for 1-2 minutes to let the flavors meld.
Garnish and Serve: Plate the pasta and garnish with fresh thyme. Serve immediately and enjoy!

Cooking Tips & Techniques

Here are some handy tips to make sure your pasta turns out perfectly every time:

Don’t Rush the Leeks: Caramelization takes time, so resist the urge to crank up the heat. Low and slow is the way to go.
Choose the Right Pasta: Long noodles like linguine or fettuccine work best for soaking up the creamy sauce.
Save Pasta Water: That starchy liquid helps bind the sauce and makes it silky smooth.
Season Gradually: Taste as you go, especially with salt and pepper, to avoid over-seasoning.
Gruyere Alternatives: If Gruyere isn’t available, try Swiss or Fontina cheese for a similar creamy texture.

Trust me, once you nail these techniques, you’ll be making this recipe like a pro!

Variations & Adaptations

Looking to switch things up? Here are a few ideas:

Gluten-Free: Use gluten-free pasta and double-check your wine and cheese for gluten-free certification.
Vegetarian: Skip the wine or use a veggie broth substitute.
Seasonal Twist: Add roasted pumpkin or butternut squash for a fall-inspired variation.
Extra Protein: Toss in grilled chicken or sautéed shrimp for a heartier meal.
Spicy Kick: Sprinkle crushed red pepper flakes while sautéing the mushrooms.

One of my favorite customizations is swapping the Gruyere for smoked Gouda—it adds a smoky depth that’s absolutely delicious.

Serving & Storage Suggestions

This pasta is best enjoyed fresh, but here’s how to make the most of it:

Serving Temperature: Serve hot and garnish with fresh thyme or parsley for a pop of color.
Pairings: Complement the dish with a crisp green salad and a glass of white wine.
Refrigeration: Store leftovers in an airtight container in the fridge for up to 3 days.
Reheating: Warm in a skillet over low heat with a splash of cream or pasta water to revive the sauce.

While the flavors deepen after a day, the creamy sauce may thicken slightly—just add a touch of liquid when reheating to bring it back to life.
