🧄 Ingredients
- 8 oz pasta (fettuccine, linguine, or short pasta like fusilli)
- 2 tablespoons olive oil
- 2 tablespoons unsalted butter
- 2 large leeks (white and light green parts only), thinly sliced
- 2 cloves garlic, minced
- 8 oz cremini or baby bella mushrooms, sliced
- Salt and pepper, to taste
- 1 teaspoon fresh thyme leaves (or ½ tsp dried)
- ½ cup dry white wine (or vegetable broth)
- ½ cup heavy cream
- 1 cup shredded Gruyère cheese
- Optional: grated Parmesan, fresh parsley, or lemon zest for garnish
👩🍳 Instructions
- Cook the pasta:
Bring a large pot of salted water to a boil. Cook pasta according to package directions until al dente. Reserve ½ cup pasta water and drain. - Caramelize the leeks:
In a large skillet, heat olive oil and butter over medium heat. Add leeks and a pinch of salt. Cook for 8–10 minutes, stirring occasionally, until soft and golden. - Cook mushrooms and garlic:
Add mushrooms and thyme. Cook until mushrooms release their moisture and begin to brown, about 6–7 minutes. Add garlic and cook another minute. - Deglaze and simmer:
Pour in the white wine and simmer until mostly reduced, about 2–3 minutes. - Make the sauce:
Lower the heat and stir in heavy cream. Let simmer gently for 2–3 minutes, then add shredded Gruyère. Stir until melted and creamy. - Toss with pasta:
Add the cooked pasta and toss to coat, using reserved pasta water as needed to loosen the sauce. - Serve and garnish:
Season with salt and pepper to taste. Top with grated Parmesan, parsley, or lemon zest if desired.
💡 Tips
- Clean leeks thoroughly—they can trap dirt between layers.
- Slice leeks and mushrooms evenly for even caramelization and texture.
- Use a dry wine like Sauvignon Blanc or Pinot Grigio for the best flavor balance.
- Gruyère melts beautifully and adds nutty depth—don’t skip it!
🔁 Variations & Substitutions
- Add protein: Top with grilled chicken, shrimp, or sautéed tofu.
- Swap cheese: Try Fontina, white cheddar, or Parmesan if you don’t have Gruyère.
- Make it gluten-free: Use your favorite gluten-free pasta.
- Vegan version: Use plant-based cream and cheese alternatives, and caramelize with olive oil only.
❓ FAQs
Can I make this ahead of time?
You can prep the sauce and leeks ahead, but for best results, cook the pasta fresh and toss everything together before serving.
What pasta works best?
Short pastas like rigatoni or fusilli hold sauce well, but long pastas like linguine also work great.
Is this dish kid-friendly?
Yes! You can reduce the wine or substitute it with broth for a milder flavor.
Can I freeze leftovers?
This dish is best fresh, but it can be refrigerated for up to 3 days. Reheat gently on the stove with a splash of cream or milk.
