Dwaeji Bulgogi (Korean Spicy Pork Stir-Fry with Onion)

Dwaeji bulgogi brings the bold, spicy-savoury character of Korean pork barbecue into a fast stir-fry format. Thin slices of pork shoulder are coated in a gochujang and gochugaru marinade sharpened with garlic, ginger and soy, then cooked quickly so the meat stays juicy while the edges caramelise. Onion and spring onion soften in the same pan, catching the glossy chilli sauce without losing all their bite. Finished with sesame oil and roasted sesame seeds, it is best served straight away with steamed rice, making it a practical weeknight dish with the depth and heat associated with Korean marinated pork.

Why this recipe works

  • Bold, savoury heat: Gochujang and gochugaru bring depth and chilli warmth, while soy sauce, garlic, ginger and sesame oil make the marinade rounded rather than one-note.
  • Fast cooking: Thin slices of pork cook in minutes, making this a high-impact stir-fry with a short active cooking time.
  • Juicy pork, tender onions: The pork sears quickly while the onion softens just enough to stay sweet and slightly crisp.

Get the most out of this recipe

Adjust the heat

  • For a gentler heat: Reduce the gochugaru and lean more on gochujang for rounded flavour without as much chilli intensity.
  • For extra heat: Increase the gochugaru slightly or finish with a pinch more at the table for a sharper chilli kick.
  • Keep the sweetness in balance: If you adjust the chilli, taste the marinade before cooking and balance with a little extra sweetness or soy as needed.

Ingredient notes

  • Choose the right pork: Boneless pork shoulder works well because it has enough fat to stay juicy during quick, high-heat cooking.
  • Use Korean chilli flakes: Gochugaru has a distinct fruity heat and coarse texture; standard chilli powder will give a different flavour and may taste harsher.
  • Slice against the grain: Thin slices cut against the grain cook quickly and feel more tender once stir-fried.

Common mistakes

  • Overfilling the pan: Too much pork in the pan at once releases moisture and prevents the edges from caramelising. Cook in batches if needed.
  • Using too little heat: A hot wok or large frying pan helps the marinade reduce and cling to the pork instead of turning watery.
  • Cooking the pork too long: Once the pork is cooked through and piping hot, take it off the heat so the slices stay juicy.

Serving ideas

  • Serve with rice: Steamed rice is the simplest pairing and helps balance the spicy, savoury sauce.
  • Add crisp vegetables: Lettuce leaves, cucumber or lightly dressed greens add freshness alongside the rich pork.
  • Finish simply: Roasted sesame seeds and extra spring onion add nuttiness, colour and a fresh bite.

  1. Slice the pork shoulder thinly against the grain. In a mixing bowl, whisk together the gochujang, gochugaru, soy sauce, dark brown sugar, garlic, ginger root and toasted sesame oil until smooth.
  2. Add the pork to the marinade and mix well until every piece is coated. Cover and leave to marinate for 20 minutes at room temperature.
  3. Meanwhile, slice the yellow onion and cut the spring onion into bite-size lengths, keeping the paler and greener parts together. Set aside so they are ready to go into the pan quickly.
  4. Heat a wok or large frying pan over medium-high heat. Add the marinated pork in a single layer (cook in batches if needed) and stir-fry for 3 to 4 minutes until the pork is mostly cooked and starting to caramelise at the edges.
  5. Add the onion and stir-fry for 2 to 3 minutes until it softens but still has a little bite. Add the spring onion and cook for 30 to 60 seconds until just wilted and glossy.
  6. Take off the heat and sprinkle over the roasted sesame seeds. Serve straight away while the pork is juicy and the sauce is clinging to the meat.

Tips

  • For the juiciest result, slice the pork as thinly as you can and keep the stir-fry hot and fast so it sears rather than stews.
  • If your pan is crowded, cook the pork in two batches; overcrowding makes it release liquid and dulls the caramelised flavour.
  • Food safety: make sure the pork is cooked through and piping hot before serving.

Substitutions

  • Replace Pork shoulder with Pork belly for a richer, more succulent bulgogi.
  • Replace Dark brown sugar with Honey for a rounder sweetness and a slightly glossier finish.
  • Replace Yellow onion with Shallot for a sweeter, softer onion flavour.

Storage

  • Refrigerate up to 3 days
  • Cool quickly, then refrigerate in a sealed container for up to 3 days. Reheat in a hot wok or frying pan with a small splash of water until piping hot; avoid overcooking or the pork will dry out. Freeze for up to 2 months and defrost overnight in the fridge before reheating.
