A good recipe for creamy pesto sauce requires pesto sauce, garlic powder, heavy whipping cream, Parmesan cheese and butter, among other ingredients. The recipe takes five minutes to prepare and 10 minutes to cook.
To make creamy pesto sauce, take 3/4 cup of heavy whipping cream and 1/4 cup of water and heat them in a small heavy saucepan over medium heat. Do this until the ingredients are sufficiently hot, but not boiling.
Next, assemble 2 tablespoons of butter, 1/4 cup of prepared pesto sauce, 1/8 teaspoon of garlic powder and 1/4 teaspoon of salt. Add these ingredients to the saucepan, reduce the heat from medium to low, and let the heat run for five minutes. Once heated, stir in 1/2 cup of Parmesan cheese until the cheese is sufficiently melted; the sauce is then ready to serve.
One particularly important aspect of this recipe is the need for the heavy cream as opposed to half and half. The heavy cream is the essential ingredient in giving the sauce its thick, creamy texture, and using half and half instead makes the sauce significantly less thick. The butter is also essential to the sauce's thickness, as butter is primarily composed of milkfat.
