Equipment

  • Mixing bowls (one for beef marinade, one for cucumber salad)
  • Cutting board
  • Chef’s knife
  • Skillet or frying pan
  • Tongs or spatula
  • Measuring cups and spoons
  • Small whisk or spoon (for mixing marinade and spicy mayo)
  • Optional: vegetable peeler (if making ribbon-style cucumbers)
  • Optional: toaster or oven for toasting the bread

Ingredients

For the Spicy Beef

  • ½ lb thinly sliced beef ribeye, sirloin, or shaved steak
  • 1 tbsp gochujang Korean chili paste
  • 1 tbsp soy sauce
  • 1 tbsp brown sugar or honey
  • 1 tbsp rice vinegar
  • 1 tsp sesame oil
  • 1 garlic clove minced
  • ½ tsp grated ginger
  • 1 tsp gochugaru Korean chili flakes, optional for extra heat

For the Quick Cucumber Salad

  • 1 cup thinly sliced cucumber
  • 1 tsp rice vinegar
  • ½ tsp sesame oil
  • ½ tsp soy sauce
  • a pinch of sugar
  • a pinch of salt
  • 1 tsp toasted sesame seeds

Sandwich Assembly

  • 2 soft sub rolls brioche buns, baguettes, or Korean milk bread
  • 2–4 tbsp spicy mayo mayo + sriracha or gochujang
  • Fresh cilantro or scallions
  • Optional: shredded lettuce pickled carrots, or kimchi for extra crunch

Instructions

Marinate the Beef

  • In a bowl, whisk gochujang, soy sauce, brown sugar, rice vinegar, sesame oil, garlic, ginger, and gochugaru.
  • Add beef and toss to coat.
  • Let marinate 10–20 minutes.

Prepare the Cucumber Salad

  • In a small bowl, toss cucumber slices with rice vinegar, sesame oil, soy sauce, sugar, salt, and sesame seeds.
  • Let sit to lightly pickle while you cook the beef.

Cook the Beef

  • Heat a skillet over medium-high.
  • Add marinated beef and cook 3–5 minutes, stirring, until browned and caramelized around the edges.

Toast the Bread

  • Lightly toast rolls or buns for 1–2 minutes for better structure.

Assemble the Sandwich

  • Spread spicy mayo on both sides of the bread.
  • Layer in:
  • Spicy beef
  • Quick cucumber salad
  • Cilantro or scallions
  • Optional additions like kimchi or shredded lettuce
  • Close, slice, and serve warm.

Notes

  • Use very thinly sliced beef: Ribeye, shaved steak, or sirloin sliced paper-thin cooks quickly and absorbs the marinade better. If your beef is thicker, freeze it for 20 minutes and slice it very thin.
  • Gochujang levels vary: Some brands are sweeter or spicier. Start with 1 tablespoon and add more heat using gochugaru or sriracha if desired.
  • Don’t over-marinate: Because the marinade contains vinegar, 10–20 minutes is ideal. Longer marinating can toughen thin beef slices.
  • Cook over high heat: This gives the beef a lightly caramelized, bulgogi-style flavor and prevents steaming.
  • Cucumber salad is key: It adds coolness and crunch that balance the spicy beef. English or Persian cucumbers work best because they stay crisp.
  • Bread options matter: Soft rolls (like brioche or hoagie rolls) soak up the spicy mayo and beef juices, while baguettes give a chewier, banh-mi–like texture.
  • Add kimchi for extra kick: A spoonful of kimchi adds acidity, crunch, and authentic Korean flavor.
  • Make it lighter: Substitute beef with chicken breast, ground turkey, or sautéed mushrooms and tofu.
  • Meal prep tip: Cook the beef and prep the cucumbers separately. Assemble just before eating so the bread stays crisp.
  • Make it spicier: Add sriracha to the spicy mayo or drizzle more gochujang onto the beef before serving.

⭐ Flavor Notes & Variations

  • Add kimchi for acidity and depth.
  • Use bulgogi sauce instead of gochujang marinade for a sweeter profile.
  • Swap beef for chicken or tofu for a lighter version.
  • Use Korean milk bread for a softer bite.
  • Add pickled carrots for a banh-mi vibe with Korean flavors.
