  • 1 loaf crusty bread such as baguette, cut into ¼” thick slices
  • 4 Tbsp extra virgin olive oil
  • 1 tsp kosher salt
  • Chocolate bars enough to cover bread
  • 1 tsp sea salt
  • Marshmallows about 1-2 per slice of bread
  • 1 cup graham crackers crushed 
  • Grill spray

Special equipment:


For crostini

  • Preheat grill to medium-high heat and coat with grill spray. Drizzle bread on both sides with olive oil, then season with kosher salt. Place directly on grill grates, cover, then cook about 2-3 minutes per side, or until bread is charred and crispy, but not burnt.
  • Place bread on a large tray. Immediately top with squares of chocolate. Chocolate will begin to melt slowly by itself, or you can throw it back on the TURNED OFF grill for 1-2 minutes to speed it up. When chocolate melts, spread to cover toast, then sprinkle on sea salt.

For marshmallows

  • I used a kitchen torch (linked above in post) to quickly roast the marshmallows on all sides. This can also be done with a gas burner on your stove. Place marshmallows on metal skewers and hold about 1-2 inches above flame and rotate slowly. Alternatively, you can hold the skewers a few inches over a hot grill, then rotate slowly until charred. Cook to your desired doneness.

To assemble

  • Sprinkle chocolate with graham cracker crumbs, then place roasted marshmallows on top. Serve immediately.
