A rich and creamy homemade Alfredo sauce inspired by restaurant-style flavor, made with butter, garlic, heavy cream, and Parmesan cheese, perfect for coating fettuccine.

  • Total Time: 20 minutes
  • Yield: 4 servings

Ingredients

  • 16 oz fettuccine pasta
  • 6 tablespoons salted butter
  • 1 tablespoon minced garlic
  • 1 teaspoon garlic powder
  • 2 cups heavy cream
  • 1 1/2 cups freshly grated Parmesan cheese
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 tablespoons chopped fresh parsley (optional)

Instructions

  1. Bring a large pot of salted water to a boil and cook fettuccine until al dente. Reserve 1/2 cup pasta water, then drain.
  2. In a large skillet over medium heat, melt butter completely.
  3. Add minced garlic and sauté for about 1 minute until fragrant.
  4. Stir in garlic powder, then pour in heavy cream.
  5. Simmer for 3–5 minutes, stirring occasionally, until slightly thickened.
  6. Gradually add Parmesan cheese, stirring continuously until melted and smooth.
  7. If needed, add reserved pasta water to adjust consistency.
  8. Season with salt and black pepper to taste.
  9. Add cooked pasta and toss until evenly coated.
  10. Remove from heat, garnish with parsley if desired, and serve immediately.

Notes

  • Use freshly grated Parmesan for the smoothest sauce.
  • Do not boil after adding cheese to prevent separation.
  • Add pasta water gradually to control thickness.
  • Stir constantly while adding cheese for a creamy texture.
  • Store leftovers in refrigerator for up to 3 days.
  • Reheat gently with added milk or cream.
  • Avoid freezing as the sauce may separate.
  • Add protein or vegetables for variation.
