This came up today as I was writing a recipe from the internet. First off, I do not use “processed cheese slices” I have not used these in 10 years, do yourself a favor, use real cheese. But for this recipe I am writing, it calls for 14 slices of cheese, so I had to figure how many cups is that for real, shredded cheese. I found the answer and checked it on several sites, all are in agreement. This is based on the understanding that a stated “slice” of cheese is the square type you would put on a sandwich or burger.
1 slice = 1/4 cup shredded cheese.
4 slices = 1 cup shredded cheese.
