Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Thinly sliced beef
Thin cuts cook quickly and stay tender. Ribeye or sirloin works best because the marbling adds flavor and juiciness.

Soy sauce
Soy sauce provides the savory backbone of the bulgogi marinade and enhances the natural beefiness of the meat.

Brown sugar
This adds subtle sweetness that balances the saltiness of the soy sauce and helps the beef caramelize when cooked.

Sesame oil
Sesame oil brings a nutty aroma and depth that is essential to bulgogi-style flavor.

Garlic
Garlic adds sharpness and warmth, intensifying the savory profile of the beef.

Gochujang
This fermented chili paste provides spice, umami, and a touch of sweetness, giving the sandwich its signature heat.

Kimchi
Kimchi adds acidity, spice, and crunch. It cuts through the richness of the meat and cheese while adding complexity.

Neutral cooking oil
A high-smoke-point oil ensures proper searing without burning.

Onion
Onions soften and caramelize alongside the beef, adding sweetness and texture.

Cheese slices
Provolone or mozzarella melt smoothly and create the classic cheesesteak creaminess.

Hoagie rolls
Soft rolls hold the filling without overpowering it and soak up the flavorful juices.

Directions

Start by marinating the sliced beef in soy sauce, brown sugar, sesame oil, garlic, and gochujang. Toss well and let it rest for at least twenty minutes to allow the flavors to penetrate the meat.

Heat a large skillet or griddle over medium-high heat and add the cooking oil. Add the onions and cook until softened and lightly caramelized. Push them to the side of the pan and add the marinated beef in a single layer. Cook quickly, stirring occasionally, until the beef is just cooked through and lightly charred at the edges.

Stir the onions back into the beef, then add the kimchi. Cook for another two to three minutes, allowing the kimchi to warm through and release its aroma. Lower the heat slightly, place cheese slices over the mixture, and cover briefly until melted.

Toast the hoagie rolls lightly if desired. Spoon the hot beef and cheese mixture into the rolls and serve immediately.
