Mushroom Pasta

This one-pot creamy mushroom pasta is my go-to when I want something cozy, sophisticated, and impossibly simple. Earthy cremini mushrooms get caramelized in butter and olive oil, then simmer together with fettuccine in a savory broth until the noodles soak up all that mushroomy flavor—finish with cream and grated Parmesan for a sauce that's silky without being heavy.

It's the kind of recipe I make for a busy weeknight or when friends drop by unexpectedly: minimal cleanup, maximum comfort. Fresh thyme and a touch of lemon zest brighten the dish, while chopped parsley gives a friendly green finish—serve with extra Parmesan and a crisp green salad.

Ingredients

  • 12 oz Dry fettuccine
  • 12 oz Cremini mushrooms, sliced
  • 2 tbsp Unsalted butter
  • 1 tbsp Olive oil
  • 1 pieces Yellow onion, finely chopped
  • 3 pieces Garlic cloves, minced
  • 1 tbsp All-purpose flour
  • 3 cups Low-sodium chicken or vegetable broth
  • 1 cup Whole milk
  • 1/2 cup Heavy cream
  • 1 cup Freshly grated Parmesan
  • 1 tbsp Fresh thyme leaves
  • 2 tbsp Fresh parsley, chopped
  • 1 tsp Lemon zest
  • 1 1/2 tsp Salt
  • 1/2 tsp Freshly ground black pepper
  • 1/4 tsp Red pepper flakes (optional)

Instructions

  1. Heat a large wide pot or deep skillet over medium-high heat. Add butter and olive oil; when butter is foamy, add sliced mushrooms in a single layer and cook without stirring for 2 minutes to brown, then stir and cook until nicely caramelized, about 4–5 more minutes.

  2. Add chopped onion and a pinch of salt; cook until onion is soft and translucent, about 3 minutes. Stir in minced garlic and cook 30 seconds until fragrant.

  3. Sprinkle flour over the vegetables and stir to coat for about 1 minute to remove the raw flour taste.

  4. Pour in the broth and milk, scraping up any browned bits from the bottom of the pan. Bring the liquid to a gentle simmer.

  5. Add the dry fettuccine, pushing the pasta down so it is mostly submerged. Reduce heat to medium-low and simmer, uncovered, stirring every few minutes to prevent sticking, until the pasta is tender and the sauce has thickened, about 12–14 minutes (cook time varies by pasta).

  6. Once pasta is al dente and sauce is creamy, stir in heavy cream, grated Parmesan, fresh thyme, lemon zest, salt, pepper, and red pepper flakes if using. Cook 1–2 minutes more to melt the cheese and bind the sauce; if sauce is too thick, add up to 1/4 cup more broth or milk to loosen.

  7. Remove from heat and stir in chopped parsley. Taste and adjust seasoning. Serve immediately with extra Parmesan and a grind of black pepper.

Tips & Notes

  • For best mushroom flavor, don't overcrowd the pan when browning—working in batches gives better caramelization.
  • If the pasta seems undercooked but liquid has evaporated, add a splash of hot broth or water and continue cooking until done.
  • Use freshly grated Parmesan for the creamiest, most authentic texture—pre-grated is drier and won't melt as well.
  • This recipe adapts easily: swap fettuccine for linguine or a shorter pasta, and use vegetable broth to make it vegetarian.
