# What goes in:

→ Pasta

01 - 12 oz fettuccine or linguine

→ Mushrooms

02 - 14 oz cremini or button mushrooms, sliced
03 - 1 tbsp olive oil
04 - 2 tbsp unsalted butter

→ Sauce

05 - 5 tbsp unsalted butter
06 - 3 cloves garlic, minced
07 - 3/4 cup plus 2 tbsp heavy cream
08 - 2/3 cup grated Parmesan cheese
09 - Salt and freshly ground black pepper, to taste
10 - Pinch of nutmeg (optional)

→ Finishing Touches

11 - 2 tbsp chopped fresh parsley or chives
12 - Additional grated Parmesan, for serving

# Directions:

01 - Bring a large pot of generously salted water to a rolling boil. Cook fettuccine or linguine according to package directions until al dente. Reserve 1/2 cup of starchy pasta water before draining.
02 - Heat olive oil and 2 tbsp butter in a large skillet over medium-high heat. Add sliced mushrooms in an even layer and cook without stirring for 3–4 minutes to develop color. Continue sautéing for another 3–4 minutes until deeply golden and all moisture has evaporated. Transfer mushrooms to a plate and set aside.
03 - Reduce heat to medium. Add remaining 5 tbsp butter to the same skillet. Cook, swirling the pan occasionally, for 3–4 minutes until the butter foams, then turns a warm golden brown and releases a nutty aroma. Watch carefully to avoid burning.
04 - Add minced garlic to the browned butter and sauté for about 1 minute until fragrant and softened, stirring constantly.
05 - Pour in the heavy cream, whisking to incorporate and scraping up any caramelized bits from the bottom of the pan. Let the sauce simmer gently for 2–3 minutes until it slightly thickens and coats the back of a spoon.
06 - Stir in the grated Parmesan cheese until melted and smooth. Season generously with salt, freshly ground black pepper, and a pinch of nutmeg if using. Return the sautéed mushrooms to the skillet and toss to combine.
07 - Add the drained pasta to the skillet, tossing gently with tongs to coat every strand in the velvety sauce. Add reserved pasta water 1 tablespoon at a time if the sauce needs loosening.
08 - Taste and adjust seasoning with additional salt or pepper as needed. Remove from heat, scatter with chopped fresh herbs, and serve immediately with extra Parmesan on the side.

# Expert Advice:

01 -
  • Brown butter does most of the heavy lifting here, so you get restaurant level depth with almost zero technique required.
  • The whole thing comes together in the time it takes to boil pasta, which means less washing up and more eating.
  • It converts effortlessly for vegan or gluten free diets without losing that cozy, indulgent feel.
02 -
  • Do not crowd the mushrooms in the pan because if they are stacked on top of each other they will steam instead of brown and you will lose that deep caramelized flavor that makes this dish special.
  • Watch the butter like a hawk once it starts foaming because the line between perfectly browned and burnt is only about thirty seconds, and your nose is the best tool for telling when it is ready.
03 -
  • Always save more pasta water than you think you need because you cannot get it back once it is gone and it is the secret weapon for fixing sauce that is too thick or too broken.
  • Let the mushrooms sit without stirring for the first four minutes, resisting every urge to move them around, because that undisturbed contact with the hot pan is what creates the golden crust that makes this dish unforgettable.
