Ingredients You’ll Need

  • 12 oz pasta (fettuccine, linguine, penne, or rigatoni)
  • 2 tablespoons olive oil
  • 2 tablespoons unsalted butter
  • 2 large leeks, white and light green parts only, thinly sliced
  • 8 oz mushrooms, sliced (cremini, shiitake, or wild mushrooms)
  • 3 garlic cloves, minced
  • 1/2 cup dry white wine (optional, or use vegetable broth)
  • 3/4 cup heavy cream
  • 1 teaspoon fresh thyme leaves (or 1/2 tsp dried thyme)
  • 1 cup grated Gruyère cheese
  • Salt and black pepper, to taste
  • Fresh parsley, chopped (for garnish)
  • Reserved pasta water, as needed

Step-by-Step Instructions

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Cook the pasta until al dente according to package directions. Reserve 1 cup of pasta water before draining. Set pasta aside.

Step 2: Caramelize the Leeks

In a large skillet, heat the olive oil and butter over medium heat. Add the sliced leeks and a pinch of salt. Cook slowly, stirring occasionally, for about 10–15 minutes until leeks are golden, soft, and slightly caramelized. Reduce heat if they begin to brown too quickly.

Step 3: Cook the Mushrooms

Add the sliced mushrooms to the skillet with the leeks. Sauté for 6–8 minutes until mushrooms release their moisture and turn golden brown. Add garlic and thyme, and cook for another minute.

Step 4: Deglaze and Add Cream

Pour in the white wine (or broth) to deglaze the pan, scraping up any flavorful bits stuck to the bottom. Let simmer for 2–3 minutes until slightly reduced.

Stir in the heavy cream and bring to a gentle simmer. Season with salt and pepper.

Step 5: Stir in Cheese and Pasta

Add the Gruyère cheese and stir until melted and the sauce is smooth. Add the drained pasta and toss to coat. If the sauce is too thick, add a splash of reserved pasta water until desired consistency is reached.

Step 6: Serve

Serve hot, garnished with chopped parsley, extra Gruyère, and cracked black pepper.

Delicious Variations & Additions

  • With Protein: Add sautéed chicken, pancetta, or crispy prosciutto.
  • Go Green: Toss in baby spinach or peas for freshness.
  • Earthy Elegance: Drizzle with white truffle oil just before serving.
  • Nutty Crunch: Top with toasted pine nuts or walnuts for texture.
  • Vegan Swap: Use plant-based butter, cream, and cheese alternatives.

Serving Suggestions

  • Dinner Party Star: Serve with a crisp white wine and arugula salad.
  • Comfort Night In: Pair with crusty bread and a glass of pinot noir.
  • Side Dish Option: Great alongside roasted chicken or grilled steak.
  • Lunch Reheat: Enjoy leftovers with a splash of cream or water to refresh the sauce.

Tips for the Best Results

  • Clean Leeks Thoroughly: Rinse between layers to remove grit.
  • Cook Leeks Slowly: Don’t rush the caramelization—it’s where the flavor develops.
  • Don’t Overcook the Pasta: Al dente texture pairs best with the creamy sauce.
  • Reserve Pasta Water: It helps emulsify and extend the sauce perfectly.
  • Use Good Cheese: Gruyère from the block (not pre-shredded) melts beautifully.

Storage & Reheating

  • Fridge: Store in an airtight container for up to 3 days.
  • Reheat: Warm gently on the stove or in the microwave with a splash of cream or water.
  • Not Freezer-Friendly: Due to the cream and cheese, freezing may affect texture.

FAQs

Can I use onions instead of leeks?
Yes, but leeks offer a milder, sweeter flavor that pairs beautifully with mushrooms.

What’s the best mushroom to use?
Cremini or shiitake offer great umami depth, but any variety works well.

Is Gruyère necessary?
It’s ideal for flavor and meltability, but you can sub with Emmental, fontina, or a good Swiss cheese.

Can I make this ahead of time?
It’s best fresh, but you can prep the mushroom-leek base in advance and reheat with fresh pasta.

How can I make it gluten-free?
Use gluten-free pasta and ensure your broth and cheese are gluten-free.
