Ingredients
Meat and Marinade
- 1 lb beef sirloin, thinly sliced
- 2 tbsp low-sodium soy sauce
- 1 tbsp sesame oil
- Optional: 1 tsp minced garlic
- Optional: 1 tsp sugar
Vegetables and Cheese
- 1 cup kimchi, chopped
- 1 medium yellow onion, sliced
- 1 cup bell peppers (any color), sliced
- 4 slices provolone or American cheese
Cooking Oil
- 2 tsp vegetable oil
Bread
- 4 hoagie rolls, toasted
Instructions
- Prepare Ingredients. Slice the beef sirloin thinly, and slice the onion and bell peppers into strips to ensure quick and even cooking.
- Marinate Beef. In a bowl, combine low-sodium soy sauce, sesame oil, minced garlic (if using), and sugar (if using). Add the sliced beef and mix well to coat. Let it marinate for at least 15 minutes to infuse flavors.
- Sauté Vegetables. Heat vegetable oil in a skillet over medium-high heat. Add the sliced onions and bell peppers and sauté until tender and slightly caramelized, about 5 minutes.
- Cook Beef. Push the sautéed vegetables to one side of the skillet. Add the marinated beef to the skillet and cook until browned and cooked through, about 5 minutes, stirring occasionally to prevent sticking.
- Add Kimchi. Mix in the chopped kimchi with the beef and vegetables and cook for an additional 2 minutes to warm through and blend the flavors.
- Assemble Sandwiches. Place the bulgogi mixture on the toasted hoagie rolls. Top each sandwich with a slice of provolone or American cheese.
- Melt Cheese. Place the assembled sandwiches under a broiler for about 2 minutes or until the cheese is melted and bubbly. Serve immediately for best taste.
Notes
- For extra spice, add a few dashes of gochujang or chili flakes to the beef marinade.
- You can substitute sirloin with ribeye or flank steak if desired.
- Toasting the hoagie rolls adds a satisfying crunch and prevents sogginess.
- If you don’t have a broiler, you may melt the cheese in a skillet covered with a lid over low heat.
- Kimchi adds a tangy spice; adjust the quantity based on your tolerance for heat and sourness.
