My neighbor brought these to our garden club meeting and everyone demanded the recipe. So simple it almost feels like cheating.

If you like herbs, add 1–2 teaspoons of dried thyme, rosemary, or Italian seasoning to the butter, or shower the finished stacks with fresh chopped parsley or chives. To make them dairy-free, swap the butter for olive oil or a neutral oil with a high smoke point, keeping in mind they may brown a bit faster.

For meal prep, you can slice and butter the potatoes a few hours ahead and keep them covered in the fridge, then stack and bake when you’re ready; just work quickly so the slices don’t discolor, and don’t soak them in water or they’ll lose the starch that helps them stick together.

Food safety notes: Always wash and scrub potatoes well to remove dirt and any surface bacteria. Discard any potatoes that are very soft, moldy, or have a strong off-odor. If your potatoes have green patches or large sprouts, cut those away generously or discard the potato, as the green parts can be bitter. Use a mandoline with the hand guard or a cut-resistant glove, and keep fingers tucked if using a knife to avoid injury. Store leftover stackers in an airtight container in the refrigerator and reheat thoroughly in a hot oven or air fryer until steaming in the center before serving.
