Over the years, the recipe has been adapted, and it's often made with heavy cream. But Alfredo sauce without heavy cream can be made, and it can be tasty.

Instructions

  • Add the minced garlic, garlic powder, italian seasoning, salt and pepper. ...
  • Bring to a simmer and continue to cook for about 3-5 minutes or until it starts to thicken.

Slowly, whisk the slurry into the simmering sauce in a pan over medium to medium-high heat. Whisk the slurry slowly into the hot sauce until you get the desired thickness.
