Creating the flavorful Ginger Onion Fried Sea Bass is simple when you follow these steps:

1. Prepare the Ingredients: Gather all ingredients and set them on a clean work surface.
2. Marinate the Fish: In a small bowl, combine soy sauce, rice vinegar, salt, and pepper. Marinate the sea bass fillets in this mixture for about 10-15 minutes.
3. Heat the Oil: In a non-stick skillet, heat the vegetable oil over medium-high heat.
4. Sauté Onions: Add the sliced onions to the skillet and sauté until they become translucent, about 3-4 minutes.
5. Add Ginger: Stir in the grated ginger, cooking for an additional 1-2 minutes until fragrant.
6. Cook the Fish: Place the marinated sea bass fillets in the skillet, skin side down. Sear for about 4-5 minutes, then carefully flip and cook for another 4-5 minutes or until the fish is cooked through and flaky.
7. Reduce Heat: Lower the heat if necessary to prevent burning, ensuring everything cooks evenly.
8. Check Doneness: Use a fork to flake the fish in the thickest part; it should easily separate when finished.
9. Serve: Once cooked, transfer the fillets to a serving plate, topped with the sautéed ginger and onion mixture for presentation.
10. Garnish: Optionally, sprinkle some chopped green onions on top for added color and flavor.

This straightforward set of steps will help guide you to create a dish that’s both elegant and delicious.
