Ingredients
  

  • ½ lb spaghetti pasta
  • 8 oz sliced mushrooms
  • 1 tbsp minced garlic
  • 1 cup heavy whipping cream
  • 1 cup chicken stock or dry white wine
  • 1 cup reserved pasta water
  • 1 cup grated Parmesan cheese
  • 2 tbsp butter
  • 2 tbsp olive oil
  • 1 tbsp each chopped fresh Italian parsley, and basil
  • Salt and freshly ground black pepper, to taste
  • Additional Parmesan and parsley for garnish

Instructions
 

  • Bring a large pot of salted water to a boil. Cook the pasta according to package directions until al dente. Reserve 2 cups of pasta water before draining.
  • In a large sauté pan, heat the olive oil and butter over medium heat. Add the chopped onion and garlic, cooking until soft and translucent.
  • Add the sliced mushrooms to the pan. Sauté until golden brown and most of the moisture has evaporated, about 10 minutes. Season with salt and pepper.
  • Pour in the chicken stock or white wine to deglaze the pan, scraping up any browned bits. Let it simmer for 2 minutes.
  • Stir in the heavy cream and reserved pasta water. Simmer the sauce gently until it thickens, about 10 minutes.
  • Stir in the Parmesan cheese and fresh herbs. Simmer for 5 more minutes. Taste and adjust seasoning with salt and pepper.
  • Add the drained spaghetti to the pan and toss well to coat in the creamy mushroom sauce.
  • Plate the pasta and top with extra Parmesan and chopped parsley. Serve immediately.

Notes

Brown the mushrooms: Let them cook undisturbed for a few minutes to develop a deeper, richer flavor. Don't overcook the garlic: Add it after the mushrooms have browned to prevent burning. Save the pasta water: The starchy water helps the creamy sauce cling to the spaghetti. Choose your pasta: Bucatini, spaghetti, linguine, or fettuccine all work beautifully. Make it your own: Add cooked chicken or shrimp if you prefer, or use vegetable broth in place of wine if a recipe variation calls for it.
