Method
Pat the oysters dry on paper towels and season lightly with 1/2 tsp salt and a pinch of black pepper.
In a small bowl combine ketchup, soy sauce, rice vinegar, sugar and chili paste (if using); stir until sugar dissolves and set aside.
In a small cup or jar whisk the sweet potato starch with 180 ml cold water until fully dissolved and smooth.
Beat the eggs in a bowl with the remaining 1/2 tsp salt.
Heat a 10–12 inch nonstick or well-seasoned cast‑iron skillet over medium‑high heat and add the oil.
Add the minced garlic and the white parts of the scallions to the hot oil and sauté until fragrant, about 1 minute.
Add the oysters, spread them into a single layer and cook until their edges just start to curl, about 2 minutes.
Pour the sweet‑potato‑starch slurry evenly over the oysters and gently stir once or twice to combine; let the mixture thicken and become glossy, about 2 minutes.
Scatter the shredded lettuce or spinach (if using) over the thickened starch mixture.
Quickly pour the beaten eggs evenly over the pan, reduce heat to medium, and let the eggs set undisturbed until mostly cooked through, about 2 minutes.
Use a wide spatula to fold the omelette in half (or flip once) and slide it onto a serving plate.
If you want the sauce slightly thicker, stir the optional cornstarch slurry (1 tsp cornstarch + 1 tbsp water) into the prepared sauce and briefly warm it in the hot skillet for 30–60 seconds; then spoon the sauce over the omelette and garnish with scallion greens and cilantro.
Worth knowing
- Sweet potato starch gives the characteristic glossy, slightly chewy texture; if unavailable use cornstarch but the texture will be less elastic (use 2 tbsp cornstarch with 180 ml water).
- If fresh oysters are hard to find, small peeled shrimp (100–150 g) can be used as a substitute — cook the shrimp the same way but reduce the oyster-cooking time to 1–1½ minutes.
- Keep the pan hot but not screeching: too high heat will overcrisp the eggs before the starch sets; medium to medium-high gives crisp edges and a tender interior.
- Work quickly when you pour the eggs — the starch sets fast so pour evenly to get a uniform omelette.
- This dish is best eaten immediately — leftover pieces reheat briefly in a skillet over medium heat to regain a bit of crispness.
