Jjajangbap (Rice with Black Bean Sauce)

Jjajangbap is the rice-bowl version of Korea’s beloved black bean sauce dishes, pairing warm steamed rice with a glossy, savoury-sweet sauce made from Korean-Chinese black bean paste. Here, pork belly gives the sauce richness, while onion, potato and courgette add sweetness, body and soft texture. A short simmer lets the vegetables become tender before the sauce is thickened so it coats the rice rather than soaking straight through it. Comforting, filling and easy to serve in bowls, it is a practical dinner with deep umami flavour and enough flexibility to suit minced pork or a lighter stock if preferred.

Why this recipe works

  • Deep savoury base: Rendering the pork belly first gives the vegetables and black bean sauce a richer, more rounded flavour.
  • Glossy sauce texture: A cornflour slurry thickens the simmered sauce so it coats the rice rather than soaking straight through it.
  • Good for planning ahead: The sauce keeps and freezes well, making it easy to reheat while cooking fresh rice to serve.

Authenticity notes

  • Korean-Chinese style: Jjajangbap belongs to the Korean-Chinese black bean sauce family, closely related to jjajangmyeon but served over rice instead of noodles.
  • Home-style flexibility: The diced pork and vegetables make this a practical home version, with the sauce acting as the main flavour base for the whole bowl.

Ingredient notes

  • Black bean sauce: The black bean sauce is the defining ingredient, bringing savoury depth, slight bitterness and a dark colour to the finished dish.
  • Even vegetable dice: Keeping the potato, onion and courgette in similar small pieces helps them cook evenly and sit neatly in the sauce.
  • Pork belly richness: Pork belly adds body as it renders; minced pork can be used when a lighter, quicker-cooking sauce is preferred.

Common mistakes

  • Do not scorch the sauce: Stir-fry the black bean sauce only briefly before adding stock, as it can catch on the wok if cooked too long without liquid.
  • Watch the thickening stage: Add the cornflour slurry to a simmering sauce and stir well so it thickens smoothly rather than forming lumps.
  • Keep the potato intact: Simmer until the potato is tender but not collapsing, so the sauce stays chunky rather than turning mushy.

Make-ahead tips

  • Store sauce and rice separately: Keep the black bean sauce separate from the rice for the best texture when reheating.
  • Freeze the sauce: The sauce can be frozen after cooling; defrost it in the fridge before reheating until piping hot.
  • Loosen as needed: Reheat gently with a splash of water if the sauce has thickened too much in the fridge or freezer.

  1. Rinse the rice in cold water until the water runs mostly clear. Tip into a large pot with the water, bring to the boil, then cover and cook on the lowest heat for 12 minutes. Take off the heat and leave, covered, for 10 minutes.
  2. Meanwhile, cut the pork belly into small cubes. Peel the onion and potato, then cut the onion, potato and courgette into 1 cm dice. Finely chop the garlic.
  3. Heat the vegetable oil in a wok over medium-high heat. Add the pork belly and stir-fry for 4 to 6 minutes until lightly browned and some fat has rendered. Add the onion and stir-fry for 2 minutes until starting to soften.
  4. Stir in the potato and courgette, then cook for 2 minutes to coat in the pork fat. Add the garlic and cook for 30 seconds until fragrant. Add the black bean sauce and caster sugar, and stir-fry for 1 minute to toast the sauce slightly.
  5. Pour in the chicken stock, bring to a gentle simmer, then cook for 10 to 12 minutes until the potato is tender and the sauce looks glossy. Whisk the cornflour with 3 tbsp cold water to make a smooth slurry. Stir it into the simmering sauce and cook for 1 to 2 minutes until thick enough to coat the back of a spoon.
  6. Fluff the rice and divide between bowls. Spoon the black bean sauce over the top and serve straight away while hot.

Recipe notes

Tips

  • Keep the simmer gentle once the stock goes in so the potato cooks through without the sauce reducing too quickly.
  • If the sauce thickens too much after adding the cornflour, loosen it with a splash of hot water and simmer for 30 seconds.
  • If serving to young children, cut the pork belly into smaller pieces and make sure the sauce is piping hot throughout before serving.

Substitutions

  • Replace Pork belly with minced pork for a lighter, quicker-cooking sauce.
  • Replace Chicken stock with vegetable broth for a cleaner flavour.
  • Replace Caster sugar with light brown sugar for a deeper sweetness.

Storage

  • Refrigerate up to 3 days
  • Cool the sauce quickly, then refrigerate in a sealed container for up to 3 days. Reheat in a saucepan over low heat with a splash of water until piping hot; cook fresh rice to serve. Freeze the sauce for up to 2 months, defrost overnight in the fridge, then reheat until piping hot.
