01 - Set a grill pan or skillet over medium-high heat and allow it to get fully hot before adding the scallions.
02 - Lay the trimmed scallions across the hot pan. Char them, turning occasionally, until deeply browned in spots and softened, about 4–5 minutes. Remove from the pan and let cool.
03 - Once cooled, finely chop the charred scallions and set aside.
04 - In a medium mixing bowl, combine the sour cream, softened cream cheese, mayonnaise, grated garlic, soy sauce, sesame oil, lime juice, salt, and pepper. Stir until the mixture is completely smooth and well blended.
05 - Gently stir the chopped charred scallions and 2–3 tablespoons of chili crisp into the dip base, adjusting the amount of chili crisp to your preferred heat level.
06 - Transfer the dip to a serving bowl. Swirl additional chili crisp over the top and sprinkle with chopped cilantro and toasted sesame seeds if desired.
07 - Serve chilled or at room temperature alongside chips, crackers, or crudités.
