How to Make Crab Rangoon Crostini

Step One: Toast the Rolls
Preheat the oven to 350 degrees F. Slice the rolls in half and place them cut side up on a large baking sheet. Bake for 8 to 10 minutes, or until lightly toasted and golden around the edges.

Step Two: Make the Filling
While the rolls are toasting, mix the softened cream cheese, drained crab meat, finely chopped green onion, Worcestershire sauce, and garlic powder in a medium bowl until well combined.

Step Three: Fill the Crostini
Remove the rolls from the oven and spread the crab mixture into the center of each roll, leaving the edges clear for easy handling.

Step Four: Heat the Filling
Return the filled rolls to the oven and bake for 2 to 5 minutes, just until the filling is warmed through.

Step Five: Finish and Serve
Remove from the oven, separate the rolls if needed, drizzle with sweet and sour sauce, and sprinkle with sliced green onions. Serve immediately.
