Peel the potatoes and place them in a bowl of cold water.
Remove one potato from the water and dry it completely.
Place the dried potato in a large wooden or metal serving spoon.
Using a sharp knife, slice the potato crosswise at ⅛-inch intervals, cutting until the knife touches the spoon without cutting all the way through.
Repeat steps 3-5 with the remaining potatoes.
Arrange the potatoes cut side up in a shallow baking dish or small roasting pan.
Drizzle half of the melted butter over the potatoes.
Season the potatoes with salt and pepper.
Bake in the preheated oven for 35 to 40 minutes.
Remove the pan from the oven and drizzle the remaining butter over the potatoes.
Sprinkle Romano cheese and bread crumbs on top of the potatoes.
Season with a little more salt and pepper.
Return the pan to the oven and bake until nicely browned, about 20 minutes.
Notes
Tips and Tricks
Use the Spoon Trick - Placing the potato in a large spoon prevents you from cutting all the way through. The spoon acts as a guide for your knife.Slice Evenly - Try to make your slices the same thickness so the potatoes cook evenly. Aim for about ⅛-inch between each cut.Soak in Cold Water - Keeping peeled potatoes in cold water prevents them from turning brown while you work on the others.Don't Skip the Second Butter - Adding more butter halfway through keeps the potatoes moist and adds extra flavor to the crispy parts.Check for Doneness - The potatoes should be tender when you poke them with a fork. If they're still firm after the first bake time, give them a few more minutes.Let Them Rest - Allow the potatoes to sit for 2-3 minutes after removing them from the oven. This makes them easier to serve without falling apart.
Storing and Reheating
Refrigerate - Store leftover potatoes in an airtight container in the refrigerator for up to 3 days.Reheat in Oven - Place potatoes on a baking sheet and reheat at 350 degrees F for 10 to 15 minutes until warmed through and crispy.Reheat in Air Fryer - Place potatoes in the air fryer basket and heat at 350 degrees F for 5 to 7 minutes until crispy and hot.
