Ingredient Notes

Creamy Fettuccine Mushroom Alfredo - 2
  • Fettuccine noodles: The base of this dish, they soak up that creamy sauce really well. I love fresh pasta, but dried works too when you’re in a pinch.
  • Baby bella mushrooms: These guys bring that rich, earthy flavor. When picking, look for ones that are firm and have no dark spots. White button mushrooms can work in a rush.
  • Salted butter: A big scoop of butter adds richness and depth. I prefer salted for the extra flavor, but unsalted’s okay if that’s what you have.
  • Heavy cream: This is what gives the sauce that luscious texture. You can swap it for half-and-half if you want something a little lighter, but it changes the creaminess.
  • Freshly grated parmesan cheese: The real deal melts beautifully into the sauce. Grab a block instead of pre-grated for the best flavor. Pecorino Romano’s a nice substitute too.

Recipe Tips

  • If the sauce turns out too thick, a splash of chicken broth or pasta water can easily help loosen it up.
  • When the alfredo sauce separates, try reheating it gently while whisking to reincorporate the fats smoothly.
  • If mushrooms release too much water, sauté them a bit longer to evaporate excess moisture before mixing into the sauce.
  • For a more vibrant dish, adding asparagus or broccoli not only improves color but also boosts nutrition.
  • For a complete meal, serving this fettuccine alfredo with a side of Caesar salad and garlic bread makes a satisfying combination.

Serving Suggestions

  1. Pair fettuccine alfredo with a Caesar salad and garlic bread. Roasted vegetables like asparagus also complement this dish well.
  2. Try incorporating grilled chicken for extra protein or use the fettuccine as a base for a vegetable medley. This creamy pasta can work in various pasta salads or combined with other proteins.
  3. Top with a drizzle of olive oil or a sprinkle of parmesan cheese for a finishing touch. A dash of black pepper can add additional flavor before serving.

Storage Guidelines

  • To keep your fettuccine alfredo fresh, follow these storage tips:
  • Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 3 days. This method keeps them chilled.
  • Freezing: For longer storage, wrap the fettuccine in plastic wrap or aluminum foil, then place in a freezer bag. Freeze for up to 2 months. To use, thaw in the refrigerator overnight.
  • Reheating: When ready to eat, reheat on the stove over low heat, stirring occasionally until warmed through. Add a splash of milk for creaminess.

Recipe Variations

  • You can use linguine noodles instead of fettuccine for a different pasta experience.
  • Add 1 teaspoon of garlic powder or ½ teaspoon of Italian seasoning to enhance the dish’s flavor profile.
  • Either use button mushrooms or shiitake mushrooms to provide a unique taste and texture.
  • If you’re making portions for a crowd, double all ingredients to serve up to 8 people comfortably.

Course: Dinner, Sauce
Cuisine: Italian

Equipment

  • Large skillet
  • Whisk
  • Measuring cups
  • Measuring spoons

Ingredients

  • 8 ounces fettuccine noodles about half of a 1 pound size box
  • 1 tablespoon olive oil (15ml)
  • 8 ounces baby bella mushrooms sliced (226g)
  • ¼ cup salted butter (57g)
  • 2 tablespoons all-purpose flour (30g)
  • ½ cup chicken broth (120ml)
  • 1 cup heavy cream (240ml)
  • ¾ cup freshly grated parmesan cheese (75g)
  • ½ teaspoon garlic powder (2g)
  • salt to taste
  • black pepper to taste
  • 1 cup fresh spinach chopped (30g)

Instructions

  • Start by boiling a pot of water until it is bubbling steadily. Add the fettuccine noodles to the pot. Cook the pasta to al dente according to package instructions, making sure to keep a close watch to avoid overcooking and ending up with mushy pasta.
  • Heat the olive oil in a large skillet over medium heat. Add the sliced baby bella mushrooms to the skillet. Sauté the mushrooms for a few minutes until they are golden brown and fragrant. Make sure not to overcrowd the pan to prevent them from steaming.
  • Add the salted butter to the skillet with the mushrooms and let it melt completely. Once melted, sprinkle in the all-purpose flour and stir constantly. This mixture will start to bubble and thicken, which is key for creating a creamy base. Avoid burning it; you want a nice, light color.
  • Gradually pour in the chicken broth while whisking continuously, followed by the heavy cream. Keep whisking until the mixture is smooth and velvety. If lumps start to form, continue whisking until everything is blended without separation.
  • Stir in the freshly grated parmesan cheese along with the garlic powder. Mix until the cheese fully melts into the sauce, making it rich and comforting. If the sauce seems too thick, add a splash of chicken broth or pasta water to reach your desired consistency.
  • Taste the sauce and add salt and black pepper as necessary. Stir thoroughly to ensure the spices are evenly incorporated. Remember to season gradually, as a little goes a long way.
  • Finally, toss the chopped spinach into the sauce and give it a final stir, allowing the spinach to wilt down and turn vibrant green. Serve the velvety mushroom Alfredo sauce over the fettuccine noodles and enjoy every creamy bite!
