Start by removing any damaged outer leaves from the medium green cabbage. Cut it into quarters with a sharp knife and carefully remove the tough core from each piece. Then, chop the cabbage into bite-sized pieces, about 2 inches wide. Rinse the chopped cabbage thoroughly under cold running water and let it drain in a colander to eliminate excess moisture.

Pat the drained cabbage dry using clean kitchen towels; this step is crucial for achieving a beautiful golden color during stir-frying. Meanwhile, peel and finely mince the six cloves of garlic, and peel and grate the fresh ginger to prepare for the savory aromatics in your Spicy Garlic Stir-Fried Cabbage.

In a small mixing bowl, combine the soy sauce, oyster sauce, rice vinegar, chili garlic sauce, brown sugar, and water. Stir the mixture until the brown sugar dissolves completely; this sauce will be the star of your dish. Set it aside, and slice three green onions into thin rounds for garnish.

Place a large wok or deep skillet over medium-high heat for about 1 minute, allowing it to become hot. Once heated, add 2 tablespoons of vegetable oil and swirl it around to coat the pan’s surface.

Add the minced garlic and grated ginger to the hot oil, stir-frying for about 20 to 30 seconds until fragrant. Be mindful not to let the garlic burn, as this can lead to bitterness. Next, add 1 teaspoon of red pepper flakes and stir for another 10 seconds.

Increase the heat to high and place half of the chopped cabbage into the hot pan. Stir-fry for 2 minutes, allowing the cabbage to soften while developing lightly browned edges.

Add the remaining cabbage to the pan and continue stir-frying for an additional 2 to 3 minutes. Toss frequently, letting some pieces contact the hot pan to develop golden caramelized spots.

Pour the prepared sauce evenly over the stir-fried cabbage, tossing everything thoroughly to ensure each piece is well-coated. Continue cooking for another 2 to 3 minutes until the cabbage becomes tender yet still retains a slight crunch.

Add 1 teaspoon of sesame oil and 1/4 teaspoon of ground black pepper to the pan. Taste and season with salt only if needed; the sauce already provides ample flavor. Stir-fry for an additional 30 seconds.

Remove the skillet from heat to prevent overcooking the cabbage. Transfer your vibrant, spicy garlic cabbage to a large serving bowl or plate. Garnish with the sliced green onions and toasted sesame seeds, and enjoy!
