In a large mixing bowl, whisk together the sweet chili sauce, minced garlic, grated ginger, soy sauce, sesame oil, lime juice, and red pepper flakes until thoroughly combined.
Carefully add the peeled and deveined shrimp to the marinade, ensuring that each shrimp is evenly coated. Allow the shrimp to marinate at room temperature for about 15-20 minutes.
While the shrimp are marinating, place a large skillet over medium-high heat. Once the skillet is hot, add the marinated shrimp along with all the marinade to the pan.
Cook the shrimp for approximately 2-3 minutes on one side, then flip and continue cooking for another 2-3 minutes, or until they turn pink and opaque.
Once cooked, remove the skillet from the heat and sprinkle the thinly sliced green onions over the shrimp. Gently toss everything together.
To serve, spoon the Sweet Chili Garlic Shrimp over a bed of fluffy jasmine rice or quinoa, and garnish with fresh cilantro.
