Pat shrimp completely dry with paper towels, then pulse in a food processor 6-8 times until coarsely chopped. Mix in egg, green onions, garlic, ginger, soy sauce, and sesame oil until just combined; avoid over-mixing to prevent gummy paste.
8 oz shrimp, 1 unit egg, 3 units green onions, 2 cloves garlic, 1 tsp fresh ginger, 1 tbsp soy sauce, 1 tsp sesame oil
Remove crusts from white bread slices using a sharp knife. Spread shrimp paste evenly on each slice in a ¼-inch thick layer, pressing gently so it sticks.
8 slices white bread, 8 oz shrimp
Brush tops of shrimp paste lightly with water or oil, then sprinkle sesame seeds evenly. Press seeds gently to help them adhere during cooking.
2 tbsp sesame seeds
Preheat air fryer to 350°F. Place shrimp toast in a single layer with 1-inch gaps between pieces. Cook for 4-5 minutes until edges start turning golden.
Carefully flip each piece using a spatula. Cook another 4-5 minutes until the bread is crispy golden and shrimp filling is opaque. Let rest for 2 minutes before serving to set the filling.
