Ingredients

For Bulgogi Beef:

  • 12 oz ribeye or sirloin steak, thinly sliced
  • 2 tbsp soy sauce or tamari
  • 1 tbsp brown sugar or honey
  • 1 tbsp sesame oil
  • 2 garlic cloves, minced
  • 1 tsp fresh ginger, grated
  • 1 tbsp gochugaru or red pepper flakes
  • 1 tbsp rice vinegar
  • Black pepper to taste

For Assembly:

  • 1 cup kimchi, chopped and drained
  • 1 large onion, thinly sliced
  • ½ cup shredded mozzarella or provolone
  • 2 hoagie rolls
  • 1 tbsp vegetable oil
  • 2 tbsp mayonnaise
  • 1 tsp sriracha (optional)
  • Green onions and sesame seeds for garnish

Instructions

  • Combine soy sauce, brown sugar, sesame oil, garlic, ginger, gochugaru, rice vinegar, and pepper. Add sliced beef and toss. Marinate at least 10 minutes (up to 2 hours refrigerated).
  • Heat ½ tbsp oil in large skillet over medium heat. Add sliced onions and cook 8-10 minutes, stirring occasionally, until golden and caramelized. Remove and set aside.
  • In same skillet over high heat, add remaining oil. Add marinated beef in single layer. Cook 2-3 minutes per side until cooked through and slightly charred. High heat creates flavorful char.
  • While beef cooks, roughly chop kimchi and squeeze out excess liquid. Optionally sauté kimchi 2 minutes to warm and mellow intensity.
  • Split and toast hoagie rolls. Mix mayo with sriracha for spicy mayo. Spread on rolls. Pile beef onto bottom halves, top with caramelized onions and kimchi. Sprinkle cheese over hot ingredients.
  • Close sandwiches and press gently. Cut in half. Garnish with green onions and sesame seeds. Serve immediately while hot and crispy.

Notes

  • Ribeye richest flavor; sirloin, flank, or skirt steak work (leaner).
  • Slice beef very thin against grain for tenderness.
  • Kimchi in Asian stores or supermarket refrigerated section.
  • Less spicy: mild kimchi, reduce gochugaru, skip sriracha.
  • Partially freeze beef 30 min for easier thin slicing.
  • Dairy-free: omit cheese (maintain 43g protein).
  • Nightshade-free: use black pepper instead of gochugaru.
  • Gluten-free: tamari + GF rolls.
  • Marinate beef and caramelize onions ahead; cook fresh.
  • Protein variations: chicken thighs, pork, or firm tofu.
