This bold and savory Korean pork stir-fry recipe stars thinly sliced pork belly, marinated in a rich blend of gochujang, soy sauce, tomato paste, and chili powder, then stir-fried to sizzling perfection with sweet red onions and garlic.

Spicy Korean Pork Stir Fry

Ingredients
  

  • 11.85 oz pork belly, 335g
  • 2 tablespoons light soy sauce
  • 1 tablespoon Gochujang sauce
  • 1 tablespoon tomato paste
  • 1 tablespoon chili powder
  • 2 teaspoons sesame oil
  • 2 tablespoons minced garlic
  • 1 medium red onion, sliced

Method
 

  1. In a large bowl, add light soy sauce, gochujang, tomato paste, chili powder, and sesame oil to the pork. Mix until evenly coated.
    2 tablespoons light soy sauce, 1 tablespoon Gochujang sauce, 1 tablespoon tomato paste, 1 tablespoon chili powder, 2 teaspoons sesame oil, 11.85 oz pork belly
  2. Add in minced garlic and sliced red onion, and mix again to combine.
    2 tablespoons minced garlic, 1 medium red onion
  3. Let marinate for at least 20 minutes.
  4. Heat a bit of cooking oil in a large skillet or wok over medium heat.
  5. Add the marinated pork mixture and stir-fry for 6–8 minutes, or until the pork is cooked through, edges are caramelized, and onions are tender.
  6. Serve with steamed jasmine rice, a sunny-side-up egg, and a side of vegetables like cucumber, seasoned leek, sesame seeds and shredded gim.

Notes

  1. Slice the pork thinly for fast cooking and better flavor absorption.
  2. Use medium heat — high heat can burn gochujang easily.
  3. Add a splash of sesame oil before serving for that glossy finish.
Storage:
  • Fridge: Up to 3 days in airtight container.
  • Freezer: Up to 1 month. Thaw overnight, then reheat gently in a pan.
 
Make-Ahead :
  • Marinate the pork in advance (up to 24 hours). The longer it sits, the deeper the flavor.
