"When you’re making this scalloped potatoes recipe, just make sure to slice the potatoes thin and most importantly, even with consistent cuts. You don’t want to have a mix of thin and thick slices because the casserole won’t cook evenly. Be careful and try to cut them thin with a mandoline (we highly recommend using a cut-safe glove with a mandoline) or sharp knife..."
