For the alfredo sauce, I used a large nonstick skillet on medium heat. Add in your butter cut into chunks (so itll melt faster). Once the butter melts, add in half and half, cream cheese (cut into chunks) and add rest of ingredients. I use a silicone coated wire whisk so I dont scratch my pan. But keep mixing, and once it comes to a low boil turn heat down to low. Keep mixing until done. Adjust seasonings depending on your taste.
