Monte Cristo Sandwich Recipe for the Blackstone Griddle

Blackstone Monte Cristo

If you’ve never made a Monte Cristo on a flat-top griddle, you’re in for a treat. This Blackstone version turns the diner favorite into a hot, crispy sandwich with a sweet-and-savory finish in under 30 minutes. Thin-sliced ham, generous melting cheese, and bread dipped in an egg and cream batter cook quickly on the griddle for a perfectly crisp exterior and gooey interior.

Think of it as French toast meeting ham and cheese—the combination is comforting, nostalgic, and reliably delicious.

No specialty deli cuts required: basic thin-sliced ham and everyday white bread work well. For richness and balance, spread mayonnaise on one slice and mustard on the other before assembling; these simple condiments cut through the richness and elevate the overall flavor.

This sandwich is ideal for brunch, lunch, or a casual breakfast-for-dinner night. It scales easily to feed a group and always draws compliments.

How To Make This Recipe

This overview outlines the main steps so you know what to expect. Follow the ingredient list and step-by-step instructions below for best results.

1. Preheat the griddle to medium-low and let it come up to temperature so the sandwiches brown evenly without burning.
2. Make the egg batter by whisking eggs with half-and-half in a shallow dish. This creates the French toast-style coating for the bread.
3. Prep the bread by dipping one side of each slice in the egg mixture and placing the dipped side down on a sheet of parchment or a tray while you assemble.
4. Assemble sandwiches by spreading mayo on one slice and mustard on the other, adding a piece of cheese to each slice, and layering ham. Stack additional cheese inside so each sandwich has a melty center.
5. Cook on the griddle – butter the surface, place the sandwiches eggy-side down, press gently with a spatula, and cover to help the cheese melt. Flip and brown the other side until the egg coating is set and both sides are golden.
6. Finish and serve by dusting with powdered sugar and serving with raspberry jam for dipping.
