Preheat oven to 350 degrees. Thinly slice a baguette and place crostinis on a baking sheet lined with parchment paper.

Drizzle crostinis with olive oil. Flip crostinis over to get oil on both sides. Season lightly with kosher salt and fresh ground pepper.

Bake for 10-15 minutes or until crostinis are dry and lightly golden.

After crosintinis have cooled off, spread Boursin cheese on each baguette.

Top with crab and garnish with green onions.
