On top of that, there is a layer of tender cooked beef mixed with small pieces of green vegetables. Melted bright orange cheese covers the beef, slightly oozing over the edges. The overall look is warm, juicy, and filling with a mix of textures and rich colors.

  • Rump steak: Freezing the steak slightly before slicing super thin helps it cook quickly and absorb the marinade better.
  • Grated pear: Adds subtle natural sweetness and helps tenderize the beef, perfect for balancing the spicy gochujang.
  • Gochujang: This Korean chili paste brings deep umami and heat; if you want less spice, use a milder chili sauce or reduce the amount.
  • Kimchi: Fermented cabbage with a spicy tang, it adds crunch and brightness—substitute with pickled vegetables if preferred.
  • Cheeses: A combination of mozzarella and American burger cheese melts beautifully, but feel free to experiment with provolone or cheddar for different flavors.
  • Baguette or ciabatta: Pick a sturdy bread that holds up to juicy fillings and toasting under the grill.

How to Make Bulgogi Cheesesteak Sandwich with Kimchi and Gochujang Mayonnaise Recipe

Step 1: Prepare and Slice the Beef

Start by placing your rump steak in the freezer for about 30 minutes — this step is a game-changer! Slightly frozen beef is much easier to slice thinly, so you’ll get those perfect strips that cook evenly and soak up all that incredible bulgogi marinade.

Step 2: Mix the Marinade and Marinate the Beef

While the steak chills, whisk together your marinade ingredients: grated pear, dark soy sauce, sesame oil, minced garlic and ginger, and that punchy gochujang. Toss your thin beef slices in the marinade and let them sit in the fridge for at least 30 minutes—overnight if you’re planning ahead—to really deepen the flavors.

Step 3: Cook the Bulgogi

Heat a skillet over medium heat with a splash of vegetable oil, then add your marinated beef. Stir fry for about 5 minutes until the beef is just cooked through and tender. Toss in the sliced spring onions and sprinkle black sesame seeds for a beautiful crunch and aroma. Give it a quick taste and adjust seasoning if necessary.

Step 4: Make the Gochujang Mayonnaise

In a small bowl, stir together mayonnaise, gochujang, a dash of rice wine vinegar, and optional gochugaru flakes for extra heat. This creamy, spicy mayo is going to be the perfect condiment to bring everything together inside your sandwich.

Step 5: Assemble and Grill the Sandwich

Slice your bread of choice lengthwise and spread that luscious gochujang mayo on both sides. Layer one side with your hot bulgogi beef, tangy kimchi, and both mozzarella and American cheese slices. Pop it under the grill for a few minutes until the cheese is melted and bubbly—watch closely so it doesn’t burn!

Garnishes

A sprinkle of fresh scallions or a pinch of toasted sesame seeds adds an extra pop visually and texturally. You might also like to add a few fresh chili slices or a drizzle of extra gochujang mayo on top for those who crave more heat.

Side Dishes

Cool cucumber salad or simple pickled veggies provide a refreshing contrast to this indulgent sandwich. Sweet potato fries or crispy chips also pair beautifully, delivering both crunch and comfort for a complete meal experience.

Creative Ways to Present

Try serving this sandwich wrapped in vintage-style parchment paper tied with kitchen twine for a casual yet charming vibe. For a party, slice into smaller sliders and serve with little bowls of extra kimchi and gochujang mayo on the side for dipping.

Make Ahead and Storage

Storing Leftovers

Wrap any leftovers tightly in foil or plastic wrap and store them in the refrigerator for up to 2 days. The flavors actually meld beautifully overnight, but to keep the bread from getting soggy, it’s best to store sandwich components separately when possible.

Freezing

The cooked bulgogi beef freezes well if you want to stash some for a quick meal later. Freeze in an airtight container for up to 2 months. Avoid freezing the bread or kimchi as they can lose texture and freshness.

Reheating

Reheat the bulgogi gently in a skillet over medium heat to maintain tenderness and juiciness. To revive the sandwich, toast the bread separately, then assemble with warmed beef and fresh kimchi for best texture and flavor.

FAQs

  1. Can I make this Bulgogi Cheesesteak Sandwich with kimchi-free options?

    Absolutely! If you’re not a fan of kimchi or don’t have it on hand, try substituting with quick-pickled cucumbers or sauerkraut for a similar tangy crunch. The sandwich will still shine with its rich bulgogi beef and spicy gochujang mayo.

  2. What cut of beef works best for this recipe?

    Rump steak is ideal because it’s lean but tender, especially when sliced thin and marinated. You can also use sirloin or ribeye if you prefer a bit more marbling and buttery texture.

  3. Is gochujang mayonnaise spicy?

    It has a mild to moderate heat level depending on the amount of gochujang used. It’s creamy enough to balance the spice while adding depth—feel free to adjust the quantity to suit your taste buds.

  4. Can I prepare parts of this recipe ahead of time?

    Yes! You can marinate the beef the night before and prepare the gochujang mayo ahead as well. When ready to eat, just cook the beef and assemble the sandwich for maximum freshness and flavor.

Final Thoughts

This Bulgogi Cheesesteak Sandwich with Kimchi and Gochujang Mayonnaise Recipe is a delightful celebration of bold flavors and textures—combining the best of Korean and American favorites into one unforgettable bite. Whether you’re cooking for yourself or sharing with friends, it’s a fun, comforting treat that never disappoints. Give it a try and watch it become a new staple in your sandwich repertoire!

Description

A flavorful fusion sandwich combining Korean bulgogi-marinated beef with the classic American cheesesteak, enhanced with creamy gochujang mayonnaise and melted cheeses on a crispy baguette or focaccia bread.

Ingredients

Scale

For the Beef Bulgogi Marinade

  • 250 g rump steak, frozen for 30 minutes then sliced thinly
  • 1 pear, grated
  • 2 tablespoons dark soy sauce
  • 1 tablespoon sesame oil
  • 3 garlic cloves, minced
  • 1 inch piece of ginger, minced
  • 1 tablespoon gochujang (Korean chili paste)
  • 2 spring onions/scallions, finely sliced
  • ½ tablespoon black sesame seeds

For Assembling the Bulgogi Cheesesteak

  • 2 tablespoons kimchi
  • 3 slices mozzarella cheese
  • 3 slices American burger cheese
  • 1 baguette or ciabatta or focaccia bread, to serve 2 people

For the Gochujang Mayonnaise

  • 2 tablespoons mayonnaise
  • 1 tablespoon gochujang
  • 1 teaspoon gochugaru flakes (optional)
  • 1 teaspoon rice wine vinegar

Instructions

  1. Prepare the Steak: Place the rump steak in the freezer for 30 minutes to firm up before slicing. Once semi-frozen, slice it into very thin strips for optimal texture.
  2. Make the Marinade: In a large bowl, combine the grated pear, dark soy sauce, sesame oil, minced garlic, minced ginger, and gochujang. Stir thoroughly to blend all ingredients into a flavorful sauce.
  3. Marinate the Beef: Add the thinly sliced beef strips to the marinade and mix to coat completely. Cover and refrigerate for at least 30 minutes, or preferably overnight for deeper flavor.
  4. Cook the Bulgogi: Heat ½ tablespoon vegetable oil in a frying pan or skillet over medium heat. Add the marinated beef and stir-fry for about 5 minutes until cooked through. Add the sliced spring onions and black sesame seeds, stir together, and season with salt, sugar, or pepper according to taste. If the pear was not very sweet, add approximately ½ teaspoon sugar to balance flavors.
  5. Prepare Gochujang Mayonnaise: In a small bowl, combine mayonnaise, gochujang, gochugaru flakes (if using), and rice wine vinegar. Mix well until smooth and set aside.
  6. Assemble the Sandwich: Slice open the baguette or chosen bread and place it on an oven-proof tray. Spread the gochujang mayonnaise evenly on both cut sides of the bread.
  7. Layer Ingredients: On one side of the bread, layer the cooked bulgogi beef, kimchi, mozzarella slices, and American cheese.
  8. Melt the Cheese: Place the assembled sandwich under a grill for a few minutes until the cheeses melt and bubble. Watch carefully to prevent burning.
  9. Serve: Remove the sandwich from the grill, wrap it in parchment paper for easier eating, and enjoy your bulgogi cheesesteak sandwich fresh and warm.

Notes

  • Step-by-step photos to guide preparation are available on the blog post.
  • Marinating overnight enhances the flavor but 30 minutes is sufficient for a quick meal.
  • Adjust sugar in the marinade according to the sweetness of the pear used.
  • Keep an eye on the sandwich while grilling to prevent burning the cheese.
