Notes

Recipe Notes
Note #1- Using a microplane to grate the parmesan creates an ideal fine shred that aids in creating a creamy sauce. However, using a microplane does take a bit of time and effort. The XOXO rotary grater is the next best option and makes grating the cheese much easier. 
Note #2- Heavy whipping cream will create the creamiest Alfredo Sauce. However, half and half, whole milk or any percentage of milk you prefer may be substituted in equal portions. 
Note #3- Parmigiano Reggiano is a true authentic Italian parmesan. It is an aged hard cheese that has a granular and crumbly texture. Additionally, this version of parmesan has a salty and nutty flavor that makes a world of difference when making Alfredo Sauce. Costco has the best price on authentic Parmigiano Reggiano.
Note #4- The photos and video show the Alfredo Sauce with 1 pound of pasta. However, for extra saucy Alfredo Pasta lower the pasta down to 8-12 ounces. 
Another option for extra saucy Alfredo Pasta is to add 1/2- 1 cup of pasta water to the sauce after the noodles have been added. The starchy water helps to expand the sauce and does a wonderful job of emulsifying with the fat and cheese. 
Note #5- Mixing the pasta with the sauce for about 2 minutes off heat will help the sauce to thicken and cling to the pasta.
