This creamy and flavorful homemade alfredo is made from scratch and is perfect with fettuccine, angel hair, or any type of pasta!


  • ½ stick unsalted butter
  • 1 Tablespoon chopped garlic
  • ¼ cup all purpose flour
  • 1 pint half and half
  • ½ cup grated or shredded parmesan cheese
  • 1 teaspoon kosher salt
  • ¼ teaspoon black pepper
  • ¼ teaspoon ground nutmeg
  • 1-2 cups pasta cooking water or milk


  1. In a large saute pan, melt butter over medium-high heat until it stops foaming. Stir in chopped garlic, allowing to cook for about 30-60 seconds, until the garlic becomes fragrant.
  2. Sprinkle in the flour and whisk to combine. Allow the mixture to cook for 1-2 minutes while stirring occasionally so it doesn't burn.
  3. Pour in half and half and whisk to combine. Lower heat to medium and cook while whisking until sauce thickens. 
  4. Remove pan from the heat and whisk in parmesan cheese, salt, pepper, and nutmeg. 
  5. If serving this with pasta, reserve 1-2 cups of the pasta cooking water to whisk into the sauce at the end to achieve the desired consistency. Milk can also be used as a substitute for this step.
