Ingredients for Caramelized Leek and Mushroom Gruyere Pasta

12 oz (340 g) pasta (fettuccine, linguine, or penne)
2 tbsp olive oil
2 medium leeks (white and light green parts only), thinly sliced
8 oz (225 g) cremini or button mushrooms, sliced
3 cloves garlic, minced
½ cup dry white cooking broth (or vegetable stock)
½ cup heavy cream
1 cup (100 g) Gruyere cheese, freshly grated
¼ tsp black pepper
Salt, to taste
¼ cup fresh parsley, chopped (optional for garnish)

Ingredient Notes:

Leeks — soak the slices in cold water and swish to remove grit.
Mushrooms — dry before sautéing to ensure a golden sear.
Gruyere — grate it fresh for the creamiest melt.

Step-by-Step Instructions

1. Cook the Pasta

Bring a large pot of salted water to a boil. Cook the pasta until al dente according to package directions. Before draining, reserve ½ cup of the pasta water.

2. Caramelize the Leeks

In a large skillet, heat olive oil over medium heat. Add the leeks and sauté for 6–8 minutes, stirring occasionally, until they’re soft and golden. Their sweetness will deepen as they caramelize.

3. Add the Mushrooms and Garlic

Add sliced mushrooms to the leeks and cook for 5–7 minutes more, until tender and lightly browned. Stir in the minced garlic and cook for another minute until fragrant.

4. Build the Sauce

Pour in the broth or stock and scrape up any browned bits from the bottom of the pan. Simmer for 2 minutes to let the flavors meld. Then, reduce the heat to low and stir in the cream. Let it simmer gently for 3–4 minutes until slightly thickened.

5. Melt in the Gruyere

Gradually add the grated Gruyere, stirring constantly until melted into a smooth, velvety sauce. Season with salt and black pepper to taste.

6. Combine Pasta and Sauce

Add the cooked pasta to the skillet and toss gently until every strand is coated. If the sauce feels too thick, add a splash of the reserved pasta water to loosen it.

7. Serve and Garnish

Transfer to plates or bowls, top with chopped parsley, and serve immediately. For an extra touch, sprinkle a bit more Gruyere on top or drizzle with a hint of truffle oil.

Tips for Perfect Leek and Mushroom Gruyere Pasta

Caramelize Slowly: Don’t rush the leeks — low and slow gives them that natural sweetness.
Use Fresh Cheese: Pre-shredded cheese won’t melt as smoothly.
Balance the Cream: Too thick? Add pasta water. Too thin? Simmer 1–2 minutes longer.
Add Heat: A pinch of crushed red pepper brings gentle warmth to the sauce.
Serve Immediately: This sauce is best enjoyed hot and silky.

Variations & Substitutions

Add Protein: Toss in grilled chicken, crispy pancetta, or sautéed shrimp.
Make It Vegan: Use oat cream or cashew cream and vegan cheese.
Try New Cheese: Swap Gruyere for Fontina, Parmesan, or white cheddar.
Add Veggies: Stir in spinach, peas, or roasted red peppers for more color.
Bake It: Transfer to a baking dish, top with breadcrumbs, and broil until golden.

Frequently Asked Questions

Can I make this ahead of time?

You can prepare the sauce in advance and store it in the fridge for up to 2 days. Reheat gently and toss with fresh pasta before serving.

Can I freeze it?

Freezing isn’t ideal — the cream sauce can separate when thawed.

What can I use instead of Gruyere?

Fontina, Emmental, or a sharp white cheddar work beautifully.

Can I use other mushrooms?

Absolutely — shiitake or wild mushrooms add even more depth.
