This is crucial. You must add fresh toppings after reheating. Old, lukewarm sour cream is a crime against humanity. Fresh butter? Yes. Fresh chives? Yes. A little grated cheese that melts on the hot potato? Absolutely yes.
Even a leftover potato can become a masterpiece with the right attitude and a generous hand with salt. Remember: you are the artist, the potato is your canvas, and the toppings are your paints. Go wild.
A Pro Tip for the Road
If you have multiple leftover potatoes, you can slice them into wedges or cubes, toss them in olive oil and seasoning, and roast them for 10 minutes at 400°F. You’ve just made potato wedges from leftover baked potatoes. It’s like time travel for spuds.
Or—and this is my personal favorite—make a potato hash. Chop the cold potato into cubes, fry them in butter with onion and bell peppers, and top with a fried egg. Instant breakfast of champions.
