In a small bowl, whisk together soy sauce, sesame oil, sriracha, brown sugar, and rice vinegar until the sugar dissolves completely. This creates your flavor base and can be set aside. While the sauce comes together, prep your vegetables: shred the cabbage into bite-sized pieces, shred or thinly slice the carrots, slice the green onions, mince the garlic, and grate the fresh ginger. Having everything prepped and ready is essential for stir-frying, where the cooking happens quickly.

Heat a large skillet or wok over medium-high heat. Add the cooking oil and let it heat until it shimmers. Add the ground beef, breaking it apart with a wooden spoon as it cooks. Once the beef begins to brown (about 2-3 minutes), add the minced garlic and grated ginger, stirring constantly for about 30 seconds until fragrant. Season with a pinch of salt and pepper. I prefer to add the aromatics midway through cooking the beef rather than at the start—this prevents them from burning while the meat releases its moisture and develops color.

Add the shredded cabbage and carrots to the skillet with the browned beef. Stir everything together and cook for 3-4 minutes, stirring occasionally, until the cabbage begins to wilt and the carrots soften slightly. The vegetables will release their moisture and create a flavorful base. I like to keep some texture in the cabbage—it shouldn't become mushy—so watch the timing carefully.

Pour the sauce from Step 1 into the skillet and stir well to coat all the beef and vegetables evenly. Add the sliced green onions and toss everything together for about 1 minute, allowing the sauce to coat the ingredients and warm through. The sesame oil and sriracha will create an aromatic, slightly spicy glaze that brings everything together.

Transfer the stir-fry to serving plates or bowls. Sprinkle sesame seeds and a drizzle of sriracha over the top for added garnish and a touch of extra flavor. Serve immediately while the dish is still hot.
