Ingredients You’ll Need

Here’s the lineup for your soon-to-be favorite pasta dish:

12 ounces pasta (fettuccine or linguine are great picks)
2 tablespoons olive oil
2 medium leeks (white and light green parts only), thinly sliced
8 ounces cremini mushrooms, sliced
3 cloves garlic, minced
1/2 cup dry white cooking broth (or vegetable stock)
1/2 cup heavy cream
1 cup shredded Gruyere cheese
1/4 teaspoon freshly ground black pepper
Salt, to taste
1/4 cup chopped fresh parsley (optional, for garnish)

Ingredient Highlights

Leeks – Mild, sweet, and way underrated. They’re like onions’ softer, friendlier cousin.
Mushrooms – Cremini add an earthy richness, but feel free to use button or wild mushrooms if that’s what you’ve got.
Gruyere cheese – Melty, nutty, and just fancy enough to make you feel like you’re dining at a bistro in Paris.
Cooking broth – Balances the creamy richness so the sauce doesn’t get too heavy.

How To Make Caramelized Leek and Mushroom Gruyere Pasta

1. Prepare the Pasta

Bring a large pot of salted water to a boil.
Cook pasta according to package instructions until al dente.
Reserve 1/2 cup of the pasta water, then drain and set aside.

2. Cook the Vegetables

Heat olive oil in a large skillet over medium heat.
Add sliced leeks, cooking for 6–8 minutes until soft and golden.
Stir in mushrooms, cooking for another 5–7 minutes until browned.
Add garlic and sauté for 1 minute, just until fragrant.

3. Make the Sauce

Pour in the cooking broth, scraping up any browned bits (that’s where the flavor hides!). Let it simmer for 2 minutes.
Reduce heat to low, stir in the cream, and simmer 3–4 minutes until slightly thickened.
Slowly stir in Gruyere until fully melted and the sauce is smooth.
Season with salt and pepper.

4. Combine and Serve

Toss pasta with the sauce, adding reserved pasta water as needed for that perfect silky consistency.
Garnish with parsley if you’re feeling fancy.
Serve immediately with maybe a glass of white wine (because why not?).

Helpful Tips for the Best Pasta

Don’t rush the leeks. Caramelizing is what gives them that sweet, mellow flavor. Let them take their time.
Gruyere is worth it. If you can’t find it, a mix of Swiss and Parmesan is a decent backup, but Gruyere makes the magic happen.
Pasta water is gold. Don’t skip it—it helps the sauce cling to every noodle like a cozy sweater.

Ever since, this has become my go-to when I want comfort food that still feels a bit elevated.

FAQs About Caramelized Leek and Mushroom Gruyere Pasta

Can I use another type of pasta?

Yes! While long noodles like fettuccine or linguine are dreamy with creamy sauces, short shapes like penne or rigatoni also work beautifully.

Can I substitute the heavy cream?

You can use half-and-half for a lighter sauce, though it won’t be quite as rich. A plant-based cream works too if you’re keeping things dairy-free.

How do I store leftovers?

Pop leftovers in an airtight container and refrigerate for up to 3 days. Reheat gently on the stovetop with a splash of broth or milk to loosen the sauce.
