These tacos use ground beef because it browns quickly and is easy to spoon into small tortillas. The cucumber and cabbage can be prepared while the beef cooks. For 500 g (1.1 lb) beef, I use 1 1/2 tablespoons soy sauce and 1 tablespoon tuna extract; that is enough seasoning without making the filling too salty.
How the Bulgogi Taco Filling Is Seasoned
The sauce is based on soy sauce, tuna extract, mirin, sesame oil, garlic, and ginger. Tuna extract supplies some of the salt and savoriness, so the soy sauce is kept to 1 1/2 tablespoons. Cook the sauce until it coats the beef instead of collecting at the bottom of the skillet.
Korean Bulgogi Tacos with Cucumber Pickles
Ground beef cooked with a reduced-soy bulgogi sauce, served in warm tortillas with cucumber pickles and red cabbage. Allergens: soy, wheat, sesame, and fish; check condiment and tortilla labels.
Keep raw beef chilled until cooking, avoid cross-contamination, and cook the filling to 71°C (160°F). Refrigerate leftovers within 2 hours.
🛒 Ingredients (Dual Measurements)
- 500 g (1.1 lb) ground beef, preferably 85% lean
- 100 g (3.5 oz / about 1/2 medium) yellow onion, finely diced
- 15 ml (1 tbsp) neutral cooking oil, only if the beef is very lean
- 22.5 ml (1 1/2 tbsp) regular soy sauce
- 15 ml (1 tbsp) Korean tuna extract (chamchi-aek)
- 30 ml (2 tbsp) mirin
- 15 g (0.5 oz / 1 tbsp packed) brown sugar
- 10 ml (2 tsp) toasted sesame oil
- 10 g (0.35 oz / about 2 cloves) garlic, minced
- 5 g (0.18 oz / 1 tsp) fresh ginger, finely grated
- 1 g (about 1/4 tsp) ground black pepper
- 200 g (7 oz / about 2 packed cups) red cabbage, finely shredded
- 30 ml (2 tbsp) rice vinegar, for the cabbage
- 12 g (0.4 oz / 1 tbsp) sugar, for the cabbage
- 1.5 g (1/4 tsp) fine salt, for the cabbage
- 1 English cucumber, about 300 g (10.6 oz), very thinly sliced
- 5 g (1 tsp) kosher salt, for drawing water from the cucumber
- 15 ml (1 tbsp) rice vinegar, for the cucumber
- 8 small flour tortillas, about 15 cm (6 inches)
- 15 g (0.5 oz / about 1/2 cup) cilantro leaves, optional
- 2 scallions, thinly sliced
- 1 lime, cut into wedges
- 15 g (0.5 oz / about 2 tbsp) toasted sesame seeds, optional
Step-by-Step Instructions
Step 1: Salt the cucumber: Put the sliced cucumber in a bowl and toss it with 5 g (1 tsp) kosher salt. Let it sit for 10 minutes. The slices will soften slightly and leave a small pool of water in the bowl.
Step 2: Season the cucumber: Drain the cucumber and rinse it briefly under cold water. Squeeze it gently, taking care not to crush the slices, then toss it with 15 ml (1 tbsp) rice vinegar. Set it aside to drain while you cook the beef.
Step 3: Prepare the cabbage: Toss the shredded red cabbage with 30 ml (2 tbsp) rice vinegar, 12 g (1 tbsp) sugar, and 1.5 g (1/4 tsp) fine salt. Massage it for about 30 seconds and leave it for at least 15 minutes. Drain off any liquid before serving.
Step 4: Mix the sauce: In a small bowl, stir together the soy sauce, tuna extract, mirin, brown sugar, sesame oil, garlic, ginger, and black pepper until most of the sugar has dissolved. Do not add salt; both the soy sauce and tuna extract already contain plenty.
Step 5: Cook the onion: Heat a wide skillet over medium-high heat. Add the neutral oil if you are using lean beef; otherwise the fat from the beef will be enough. Cook the diced onion for 2–3 minutes, stirring occasionally, until it begins to soften.
Step 6: Brown the beef: Add the ground beef and spread it across the hot skillet. Leave it alone for about 1 minute so the underside can brown, then break it into small pieces. Cook for another 4–5 minutes, until no pink remains. Spoon off excess fat if there is more than a thin coating in the pan.
Step 7: Reduce the sauce: Pour the sauce over the beef and stir to coat it evenly. Cook for 2–3 minutes, stirring often. It is ready when the sauce clings to the meat and there is no loose liquid at the bottom of the skillet. Taste before adding any additional seasoning because tuna extract varies by brand.
Step 8: Warm and fill the tortillas: Warm the tortillas in a dry skillet, turning once, until soft and flexible. Divide the beef among them, then add the drained cabbage and cucumber. Top with cilantro, scallion, sesame seeds, and lime juice, and serve while the tortillas are warm.

💡 A Few Useful Swaps
- Ground beef: Ground turkey works, but add the neutral oil and stop cooking as soon as it reaches 74°C (165°F).
- Tuna extract: Fish sauce can substitute in a smaller 10 ml (2 tsp) amount; taste before adding more.
- Flour tortillas: Use well-warmed corn tortillas for a gluten-free option, and verify every sauce label.
🍽️ What Goes Well With It
- Serve with steamed corn, a simple fruit salad, or cold barley tea.
❓ Frequently Asked Questions (FAQ)
Q: What is Korean tuna extract?
Korean tuna extract, called chamchi-aek, is a salty liquid seasoning made with tuna. This recipe uses 15 ml (1 tbsp) and reduces the soy sauce to 22.5 ml (1 1/2 tbsp).
Q: Can I prepare the vegetables ahead?
Yes. Refrigerate the cucumber and cabbage in separate containers for up to one day. Drain them again before putting them on the tacos.
Q: Can I use corn tortillas?
Yes. Heat them well before filling so they do not crack. Small corn tortillas may need to be doubled if the filling is especially juicy.
Q: How should I store leftovers?
Refrigerate the beef and vegetables in separate airtight containers within 2 hours. Use the beef within 3 days and reheat it to 74°C (165°F).
Serving Tip: Drain the cucumber and cabbage once more before filling the tortillas so the bottoms do not become soggy.
