Notes
Slice potatoes as thinly as possible.
Shred your own cheese from a block for the best results. Fresh herbs (such as thyme or rosemary) and garlic can be added to the sauce if desired.
To reduce baking time, wrap casserole dish in plastic wrap before adding the cheese sauce and microwave on full power for about 10 minutes (be careful, it will be hot when removing the plastic wrap). Add the cheese sauce and bake as directed for about 45-55 minutes.
Additional cheese (cheddar or parmesan) can be sprinkled on top once the foil is removed if desired. https://www.spendwithpennies.com/wprm_print/121950
