Peel and finely dice the garlic and ginger. Finely dice the chilli removing the seeds if you prefer it less hot. Quarter the brussel sprouts.
Heat 1 tbsp of oil in a large non-stick pan over medium-high heat.
Add the ginger, garlic, and chili, sautéing for about 30 seconds. Add the quartered Brussels sprouts and stir-fry for 2-3 minutes until they begin to char slightly.
Add 4 tbsp of water, cover with a lid, and steam for 3-5 minutes until the sprouts are just tender but not mushy. Stir occasionally and add more water if needed.
Remove the lid and add the gochujang, soy sauce, rice vinegar, and maple syrup, stirring well to coat. Cook for another 2 minutes until the sauce thickens slightly.
Drizzle with toasted sesame oil, then toss the sprouts gently to combine.
Serve garnished with toasted sesame seeds and sliced spring onions. Enjoy!
