Prepare the Filling
In a mixing bowl, combine the softened cream cheese, crab meat, green onions, garlic powder, soy sauce, salt, and black pepper. Mix until well combined.
Assemble the Crab Rangoon
Lay out the wonton wrappers on a clean surface. Place about one tablespoon of the crab filling in the center of each wrapper.
Lightly moisten the edges of the wrapper with water using your finger, then fold the corners of the wrapper toward the center to form a triangle or a pouch, sealing the edges tightly to prevent the filling from spilling out.
Make the Sweet Chili Sauce
In a small bowl, mix together the sweet chili sauce, rice vinegar, and sesame oil (if using). Stir until well combined and set aside for dipping.
Fry the Crab Rangoon
Heat about 2-3 inches of vegetable oil in a frying pan or deep fryer over medium-high heat to 350°F (175°C).
Carefully drop the Crab Rangoon into the hot oil, a few at a time, ensuring they don’t overcrowd the pan. Fry for 2-3 minutes, or until golden brown and crispy on all sides.
Use tongs or a slotted spoon to remove the Crab Rangoon from the oil and place them on a paper towel-lined plate to drain any excess oil.
Serve
Arrange the crispy Crab Rangoon on a serving platter and serve with the sweet chili sauce for dipping.
