We were skeptical of the supermarket potato products used here but found ourselves delighted with the results: Instant potato flakes make for a soufflé with concentrated potato flavor, presliced spuds are simply made for gratins, and canned sweets yield a deliciously gooey casserole. All offer significant time savings, too.
Just take a look at this Easy, Cheesy Potato Gratin.
Refrigerated presliced potatoes slash tons of prep and cook time. The combo of Gruyère and Parm-Regg cheeses is delicious, but you can use all one type if you prefer.
