How to Make Korean Beef Tacos

Step 1: Marinate the Beef
Thinly slice 1.5 lbs flank steak against the grain.

In a medium bowl, combine: 4 tbsp sesame oil, 4 minced garlic cloves, 1 tbsp grated fresh ginger (optional)

1/4 cup soy sauce, 1/4 cup packed brown sugar, 1 tsp ground black pepper, 1/4 cup hot water

Pour over the beef, mix well, cover, and refrigerate for 4 hours or overnight.

Step 2: Cook the Beef
Let marinated beef rest at room temperature for 30 minutes.

Heat a large nonstick skillet over high heat.

Add the beef in batches (no extra oil needed) and sear 2–3 minutes without stirring, then stir and cook for another 3–5 minutes until browned and caramelized. Set aside.

Step 3: Make the Creamy Sriracha Sauce
Whisk together: 1/3 cup sour cream, 1/4 cup mayonnaise, 1 tsp garlic powder, 1 tsp Sriracha, 2 tbsp fresh lime juice

For easy drizzling, place in a zip-top bag and snip the corner.

Step 4: Toast the Tortillas
Warm 12–14 small tortillas (6-inch) on a dry skillet or directly over gas flame until slightly charred.

Step 5: Assemble the Tacos
Top each tortilla with:

A generous portion of beef

Shredded purple cabbage

Fresh cilantro

Sliced avocado

Drizzle of creamy Sriracha sauce

Optional: extra lime wedges for serving

What to Serve With Korean Beef Tacos

Kimchi or pickled vegetables for a tangy kick

Steamed jasmine rice or sticky rice

Variations / Substitutions

Swap chicken or tofu for a different protein

Try gochujang mayo as an alternate sauce

Storage & Reheating Tips

Store leftover beef in an airtight container for up to 3 days

Reheat in a skillet until warmed through

Store sauce and toppings separately for best texture
