Mix dipping sauce ingredients together in a small bowl. Set aside. Add prawn paste mix ingredients to a blender and blitz until smooth.
Pour sesame seeds into a wide bowl.
Drizzle oil over baguette slices then coat one side with the prawn paste (about 1 ½ tbsp per slice), then dunk in sesame seeds until evenly coated.
Preheat the air fryer to 370°C. Place 4-5 sesame prawn toasts, prawn side up, in the air fryer tray and air fry for 5-7 minutes, until golden on top and cooked through. Repeat in batches with remaining sesame prawn toasts.
Serve sesame prawn toasts hot with the dipping sauce.
Tip #1: You can use any leftover bread, sliced to your desired size and shape.
Tip #2: You may need to take a blade out of the air fryer to stop the prawn toasts moving.
