You’ll need a mandoline slicer or a very sharp chef’s knife!
I cannot recommend having a mandoline slicer in your kitchen enough! I swear by this tool whenever I need thin layers of any vegetable. The key to this recipe is cutting those potatoes super thin (about ⅛-inch thick) and a good mandoline slicer makes it a breeze. If you don’t have a mandoline slicer and don’t want another kitchen gadget, you can use a sharp chef’s knife. It will take more time and the slices will likely be less uniform, so just try to slice them as thinly and evenly as you can.
Use fresh herbs for your potato stacks—it makes a huge difference!
I like using fresh herbs for my potato stacks instead of dried. Something about the freshly chopped herbs really makes a difference, plus that little effort elevates the look of the potatoes. I love some fresh thyme and rosemary, chopped and sprinkled on top of the finished potatoes. Finish them off with a little microplane grate of fresh Parmesan to put them over the top!
Bake potato stacks in a muffin tin for perfect stacks.
My special trick is to stack them up in a muffin tin! That way everyone gets their own little stacks. It’s also much easier to make sure they stay stacked and don’t topple over if you bake them in a muffin tin. It just makes the whole process easier. Remember to press down on the stacked potatoes so that they are compressed in the tin—then add more potato slices as needed so the potatoes are stacked above the tin. The potatoes will shrink as they bake.
Can you reheat potato stacks?
If you have leftovers, you can reheat them in a 200 degree oven for about 5 minutes. You may want to keep the cooked stacks in the muffin tin while reheating so they retain their shape. The stacks may fall over a bit if you reheat them in other flat baking trays. Disclaimer: These potato stacks are best served straight out of the oven!
