Creamy Mushroom Alfredo Fettuccine: From Prep to Plate

  • Bring a large pot of salted water to a boil. Add the 12 ounces of fettuccine pasta and cook according to package directions until al dente—usually about 10-12 minutes. Once done, reserve about ½ cup of the pasta water, then drain the noodles and set aside.
  • While the pasta cooks, heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the chopped onion and cook for about 3-4 minutes until softened and translucent. Stir in the minced garlic and cook for another 1-2 minutes, being careful not to let it burn.
  • Add the sliced mushrooms to the skillet. Cook for 5-7 minutes, stirring occasionally, until the mushrooms release their moisture and start to brown.
  • Pour in the 1 cup of heavy cream and stir to combine with the mushrooms, onion, and garlic. Bring the mixture to a gentle simmer and let it reduce slightly for 3-5 minutes, stirring occasionally.
  • Gradually sprinkle in the 1 cup of grated Parmesan cheese, stirring constantly to melt it smoothly into the sauce. Season with salt and black pepper to taste. If the sauce feels too thick, add a splash of the reserved pasta water to loosen it up.
  • Add the cooked fettuccine to the skillet with the sauce. Toss everything together gently but thoroughly, ensuring the noodles are fully coated in the creamy mushroom Alfredo sauce.
  • Sprinkle the chopped fresh parsley over the top for a bright, fresh note and a pop of color. Serve immediately while warm and creamy.

Notes

  • Store sauce and pasta separately for best freezer results; thaw sauce overnight and reheat gently.
  • Use freshly grated Parmesan cheese for optimal melt and flavor.
  • To keep sauce smooth, simmer gently and add reserved pasta water if needed.
  • Try seasonal vegetable additions like peas, asparagus, or sun-dried tomatoes for variety.
  • For a dairy-free version, substitute heavy cream with coconut milk and use dairy-free cheese.
