Ingredients

  • 12 oz fettuccine pasta (or your favorite pasta shape)
  • 2 tbsp unsalted butter
  • 3 cloves garlic, minced
  • 1 ½ cups heavy cream (can substitute with half-and-half for lighter option)
  • 1 cup freshly grated Parmesan cheese
  • Salt and freshly ground black pepper, to taste
  • ¼ tsp ground nutmeg
  • Fresh parsley, chopped (for garnish)
  • Optional vegetables: 1 cup sliced mushrooms, 1 cup baby spinach, or steamed broccoli florets

Equipment

  • Large pot for boiling pasta
  • Large skillet or saucepan
  • Wooden spoon or silicone spatula
  • Colander for draining pasta
  • Grater for Parmesan cheese
  • Measuring cups and spoons

Instructions

  1. Cook the pasta: Bring a large pot of salted water to a boil. Add the fettuccine and cook according to the package instructions until al dente. Reserve ½ cup of pasta water, then drain the pasta and set aside.
  2. Sauté the garlic: In a large skillet over medium heat, melt the butter. Add the minced garlic and sauté for about 1-2 minutes, until fragrant but not browned.
  3. Add cream and season: Slowly pour in the heavy cream, stirring constantly. Bring to a gentle simmer and let it cook for 3-4 minutes, allowing it to thicken slightly. Add salt, pepper, and nutmeg to the sauce.
  4. Incorporate Parmesan cheese: Gradually add the freshly grated Parmesan cheese to the sauce, stirring continuously until melted and smooth. If the sauce gets too thick, add a splash of the reserved pasta water to loosen it.
  5. Add optional vegetables: If using veggies like mushrooms or spinach, add them now. Cook until the vegetables are tender and well incorporated into the sauce.
  6. Toss pasta with sauce: Add the cooked pasta directly into the skillet with the Alfredo sauce. Toss gently to coat every strand evenly. If needed, add more reserved pasta water to achieve your desired sauce consistency.
  7. Serve immediately: Plate the pasta, garnish with chopped fresh parsley, and a light sprinkle of extra Parmesan cheese if desired. Serve warm.

Tips & Variations

For best results, always use freshly grated Parmesan cheese instead of pre-grated. It melts better and gives a richer flavor.

  • Make it vegan: Swap butter for olive oil, use coconut cream or cashew cream instead of heavy cream, and choose a plant-based Parmesan alternative. Check out our Vegan Bechamel Sauce Recipe for Creamy Pasta Dishes for ideas on creamy vegan sauces.
  • Add veggies: Enhance nutrition and texture by stirring in steamed broccoli, sun-dried tomatoes, or sautéed mushrooms. For inspiration, try our Vegetable Alfredo Recipes for Creamy, Healthy Dinners.
  • Use different pasta: While fettuccine is classic, penne, rigatoni, or spaghetti all work beautifully with Alfredo sauce.
  • Lighten it up: Use half-and-half or whole milk instead of heavy cream. The sauce will be less rich but still satisfying.
  • Make it spicy: Add a pinch of red pepper flakes when sautéing the garlic for a subtle kick.
