Croque Monsieur Baked Potato

A Croque Monsieur-Inspired Baked Potato

Chef Frank roasts his potatoes in a salt crust and shares the recipe.

ICE Chef Frank Proto prepares a professional-level potato on Epicurious' 4 Levels series using all of the toppings that are usually on a traditional Croque Monsieur sandwich.

Chef Frank demonstrates how to prepare a flavorful baked potato with crispy skin (and a bed of cheese). He uses a German butterball potato for dryness, fluffiness and a little bit of waxiness; flavored salt for a slight thyme flavor; and meat to add flavor. The base of his filling is Italian speck, a slightly smoky ham, and he tops the stuffed potato with French bechamel sauce and rich, grated Gruyere.
