Skip the box and make this easy homemade cheesy potato casserole using spiralized potatoes. YUM!
Preheat the oven to 375º. Coat a 9x9 casserole dish with cooking spray.
Spiralize the potatoes into slices, rinsing and drying after. (Slice 1/4" thick if you don't have a spiralizer). Feel free to peel the skin if desired.
Season with additional salt and pepper, if desired. Serve immediately.
