A good, yet simple Alfredo sauce recipe includes butter, whipping cream, a block of Parmesan cheese, and salt and pepper to taste. A stainless steel pot is also necessary. However, it's possible to prepare the sauce partially in the microwave, but this method results in a less rich flavor.
Start by putting 2 tablespoons of butter into the pan, turning the pan up to medium and letting the butter melt. Avoid letting it brown; this takes away from the color of the final product. When the butter has fully melted, slowly pour 1 cup of whipping cream into the pan, allowing it to mix with the butter. At this point, a pinch of salt, pepper or other spices can add extra flavor of the sauce. Garlic salt also makes an excellent addition when used sparingly.
At this point, the sauce remains runny. Bring it to a rolling boil, and stir frequently to prevent it from sticking to the sides of the pan. It should thicken within five minutes. Turn off the heat, and add 1/2 cup of freshly grated Parmesan cheese. Stir thoroughly until the cheese and sauce blend. To add a unique flavor to the sauce, try a different type of cheese, such as Romano or Provolone. This recipe should produce enough sauce to pour over four servings of pasta, so adjust the amounts as required.
