Why You’ll Love the Korean Steak Sandwich

Before we get to the recipe, let’s talk about why this sandwich is so special. The Korean Steak Sandwich is a beautiful fusion of tender, marinated beef, tangy pickled vegetables, and a creamy, spicy sauce, all nestled between perfectly toasted bread. It’s inspired by the bold flavors of Korean BBQ—think soy sauce, sesame oil, garlic, and a touch of sweetness—paired with the satisfying crunch of a classic sandwich. The result? A handheld meal that’s bursting with umami, spice, and freshness.
I first fell in love with this sandwich at a food truck festival a few summers ago. The line was long, the sun was blazing, but one bite of that perfectly balanced sandwich made it all worth it. The way the savory steak mingled with the bright, tangy pickles and the kick of gochujang mayo had me hooked. I knew I had to recreate it at home, and after some trial and error (and a lot of taste-testing), I landed on a recipe that’s just as good—if not better—than the original.
This sandwich is perfect for weeknight dinners, weekend gatherings, or even meal prep if you want to make a batch to enjoy throughout the week. It’s versatile, customizable, and guaranteed to impress anyone who takes a bite. Ready to make it? Let’s get started!
Ingredients for the Korean Steak Sandwich

To make four generous sandwiches, here’s what you’ll need. I’ve broken it down into sections for the steak, pickled vegetables, gochujang mayo, and sandwich assembly. Don’t worry if the list looks long—most of these ingredients are pantry staples or easy to find at your local grocery store or Asian market.
For the Korean-Marinated Steak:
- 1 lb flank steak or ribeye (thinly sliced for quick cooking)
- ¼ cup soy sauce (low-sodium works great)
- 2 tbsp sesame oil
- 2 tbsp brown sugar
- 3 cloves garlic, minced
- 1-inch piece of fresh ginger, grated
- 1 tbsp rice vinegar
- 1 tbsp gochujang (Korean red chili paste, adjust for spice preference)
- 1 tsp black pepper
- 1 tbsp toasted sesame seeds (optional, for extra flavor)
For the Quick-Pickled Vegetables:

- ½ cup thinly sliced red onion
- ½ cup rice vinegar
- ¼ cup water
- 2 tbsp sugar
- 1 tsp salt
- 1 tsp sesame seeds (optional)
For the Gochujang Mayo:

- 1–2 tbsp gochujang (adjust to taste)
- 1 tsp sesame oil
- 1 tsp lime juice or rice vinegar
- 1 tsp honey (optional, for a touch of sweetness)
For the Sandwich Assembly:

Step-by-Step Recipe: How to Make a Korean Steak Sandwich
Now that you’ve got your ingredients, let’s walk through the process. I’ve broken it down into manageable steps to keep things simple, but don’t be afraid to add your own flair as you go!
Step 1: Marinate the Steak
The key to a flavorful Korean Steak Sandwich is a well-marinated steak. In a large bowl, whisk together the soy sauce, sesame oil, brown sugar, minced garlic, grated ginger, rice vinegar, gochujang, black pepper, and sesame seeds (if using). Add the thinly sliced steak, making sure each piece is fully coated in the marinade. Cover and refrigerate for at least 30 minutes, but if you have time, let it marinate for 2–4 hours for maximum flavor. Trust me, the longer it sits, the better it gets.
Pro tip: If you’re short on time, even 15 minutes of marinating will do wonders. Just make sure to massage the marinade into the meat for even coverage.
Step 2: Make the Quick-Pickled Vegetables
While the steak is marinating, let’s whip up those tangy pickled veggies. In a small saucepan, combine the rice vinegar, water, sugar, and salt. Heat over medium until the sugar and salt dissolve, stirring occasionally. Place the shredded carrots, sliced cucumber, and red onion in a heatproof bowl or jar, then pour the warm pickling liquid over the vegetables. Sprinkle in the sesame seeds, if using, and let the mixture sit for at least 20 minutes. You can make these ahead and store them in the fridge for up to a week—they’re great on salads and tacos, too!
Step 3: Prepare the Gochujang Mayo
This creamy, spicy spread is the secret weapon of the Korean Steak Sandwich. In a small bowl, mix the mayonnaise, gochujang, sesame oil, lime juice, and honey (if using) until smooth. Taste and adjust the seasoning—add more gochujang for heat or a touch more honey for sweetness. Set it aside or refrigerate until you’re ready to assemble the sandwiches.
I love how this mayo adds a creamy contrast to the bold flavors of the steak and pickles. It’s so good, I’ve been known to sneak a spoonful straight from the bowl (no judgment, right?).
Step 4: Cook the Steak

Heat a large skillet or grill pan over medium-high heat and add a drizzle of oil. Remove the steak from the marinade, letting the excess drip off, and cook for 2–3 minutes per side, depending on the thickness of your slices and how done you like your steak. I prefer mine medium-rare for maximum tenderness, but cook it to your liking. Once done, transfer the steak to a cutting board and let it rest for 5 minutes before slicing it thinly against the grain.
Step 5: Toast the Bread
While the steak rests, let’s get that bread ready. Slice your rolls in half and spread a thin layer of butter or oil on the cut sides. Toast them in a skillet or on a grill pan over medium heat until golden and slightly crispy. This step is crucial—it adds crunch and keeps the bread from getting soggy when you pile on the fillings.
Step 6: Assemble the Sandwiches
Now for the fun part! Spread a generous layer of gochujang mayo on both sides of each toasted roll. On the bottom half, layer a handful of arugula or mixed greens, followed by a portion of the sliced steak. Top the steak with a generous scoop of pickled vegetables, a few cilantro leaves, and a couple of jalapeño slices if you’re feeling spicy. Place the top half of the roll on the sandwich, and you’re ready to dig in!
Serving Suggestions and Variations
This Korean Steak Sandwich is a meal in itself, but I love pairing it with a side of crispy sweet potato fries or a simple cucumber salad for a complete spread. If you’re serving it at a gathering, cut the sandwiches into smaller pieces for easy sharing—they’re always a hit at parties.
Want to mix things up? Here are a few variations to try:
- Swap the protein: Try this recipe with thinly sliced pork, chicken, or even tofu for a vegetarian twist.
- Change the bread: Swap the rolls for soft bao buns or a crusty baguette for a different texture.
- Add more veggies: Throw in some sliced radishes or pickled daikon for extra crunch.
- Make it spicier: Double up on the gochujang or add a drizzle of sriracha for an extra kick.
A Personal Touch: Why I Love This Sandwich
I’ll let you in on a little secret: I’m a bit of a sandwich nerd. There’s something so satisfying about layering flavors and textures between two pieces of bread and taking that perfect first bite. This Korean Steak Sandwich holds a special place in my heart because it reminds me of summer afternoons spent experimenting in the kitchen with my family. My husband, who’s usually a meat-and-potatoes guy, couldn’t stop raving about this one, and my kids even asked for seconds (a rare win!). It’s become our go-to when we want something quick but packed with flavor.
Cooking is all about creating moments, whether it’s a quiet dinner at home or a lively gathering with friends. This sandwich brings people together with its bold, shareable flavors, and I hope it does the same for you.
Tips for Success
- Thinly slice the steak: For tender, easy-to-eat bites, slice the steak as thinly as possible. If you’re struggling to cut it, pop it in the freezer for 15 minutes to firm it up.
- Don’t skip the resting step: Letting the steak rest after cooking keeps it juicy and flavorful.
- Adjust the spice level: Gochujang can be intense, so start with a smaller amount and taste as you go.
- Make it ahead: The pickled veggies and gochujang mayo can be prepped a day or two in advance to save time.
Final Thoughts
The Korean Steak Sandwich is more than just a meal—it’s an experience. From the savory, umami-packed steak to the bright, tangy pickles and creamy gochujang mayo, every bite is a celebration of flavor. Whether you’re making it for a quick weeknight dinner or a weekend cookout, this sandwich is sure to impress.
