Ingredients List
To create the ultimate Korean steak sandwich, you will need the following ingredients:
- 1 lb flank steak or sirloin, thinly sliced against the grain
- 1/4 cup soy sauce
- 2 tablespoons brown sugar
- 2 tablespoons sesame oil
- 3 cloves garlic, minced
- 1 tablespoon ginger, freshly grated
- 1 tablespoon gochujang (Korean chili paste)
- 1 tablespoon rice vinegar
- Freshly ground black pepper, to taste
- 4 crusty sandwich rolls or sesame seed buns
- 1 cup coleslaw mix (cabbage, carrots, and green onion)
- 1/4 cup mayonnaise
- 2 tablespoons sriracha (optional, for heat)
- Fresh cilantro or sesame seeds, for garnish
Feel free to substitute the flank steak with a more affordable cut like ribeye, or opt for chicken or tofu for a delicious twist. If you prefer a milder flavor, you can reduce the amount of gochujang.

This Korean steak sandwich can be ready in just 30 minutes, which is about 30% less time than the average gourmet sandwich recipe. Here’s the breakdown:
- Preparation time: 10 minutes
- Marinating time: 10 minutes
- Cooking time: 10 minutes
In total, you can indulge in this savory delight in less than half an hour!
Step-by-Step Instructions
Step 1: Marinade Preparation
In a bowl, combine the soy sauce, brown sugar, sesame oil, minced garlic, grated ginger, gochujang, rice vinegar, and black pepper. Mix well until the sugar dissolves. This marinade is the heart of your sandwich, and it’s where the flavor magic begins.
Step 2: Marinate the Steak
Place the sliced steak in a resealable plastic bag and pour the marinade over it. Seal the bag and gently massage it to ensure the steak is evenly coated. Let it marinate in the refrigerator for at least 10 minutes. For deeper flavor, you can marinate it for up to 2 hours.
Step 3: Preheat Your Grill or Pan
While the steak is marinating, preheat your grill or skillet over medium-high heat. A hot surface is essential to achieve a great sear on the beef.
Step 4: Cook the Steak
Once the grill or skillet is hot, remove the steak from the marinade (discard the marinade) and cook for about 3-4 minutes on each side or until the meat is browned and cooked to your liking. Avoid overcrowding the pan; if necessary, cook in batches for the best results.
Step 5: Prepare the Sauce
While the steak is cooking, mix the mayonnaise and sriracha in a small bowl. This creamy, spicy sauce will add a delightful kick to your sandwich.
Step 6: Assemble the Sandwich
Slice your rolls in half and spread the sriracha mayo generously on both sides. Layer on the cooked steak, top with coleslaw mix, and sprinkle cilantro or sesame seeds for an extra burst of freshness. The crunch of the coleslaw beautifully complements the tender steak.
Step 7: Serve & Enjoy
Serve your Korean steak sandwiches warm, and if you’re feeling adventurous, pair them with some kimchi or a side of spicy pickles for an authentic touch.

Healthier Alternatives for the Recipe
If you’re looking to make this Korean steak sandwich a bit healthier, consider these options:
- Use whole-grain rolls instead of white bread to increase fiber.
- Swap out mayonnaise for Greek yogurt mixed with spices to cut down on calories.
- Incorporate more vegetables like sliced cucumbers or bell peppers into your sandwich for added crunch and nutrition.
- Try using leaner cuts of meat, such as chicken breast or portobello mushrooms, to reduce fat content while still enjoying the flavors.
Serving Suggestions
Presenting your Korean steak sandwich creatively can enhance its appeal:
- Pair with sweet potato fries for a tasty side that complements the flavors.
- Serve with a small bowl of kimchi or a side salad for a well-rounded meal.
- Offer a variety of sauces on the side, such as hoisin or extra gochujang, for guests to customize their sandwiches.

Common Mistakes to Avoid
Even the best cooks can make mistakes; here are some common pitfalls to avoid when preparing your Korean steak sandwich:
- Over-marinating the meat can lead to a mushy texture; stick to recommended times.
- Not letting the steak rest after cooking can result in dry pieces; allow it to rest for a few minutes before slicing.
- Using insufficient heat when cooking the steak can prevent the ideal sear and flavor development; ensure your pan or grill is properly preheated.
Storing Tips for the Recipe
If you have leftovers (though we doubt it!), here are some tips for storing them effectively:
- Store the cooked steak separately from the sandwich ingredients to maintain freshness. Use airtight containers.
- Leftover sandwiches can be wrapped tightly in foil or plastic wrap, but they are best enjoyed fresh.
- Reheat leftover steak gently in a skillet or microwave to avoid overcooking.
