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.
