Directions:
1. Marinate the Beef:
Blend all marinade ingredients until smooth. Pour into a bowl, add beef and onions, mix until coated. Marinate at least 30 min or overnight for best flavor. (1*)
2. Cook the Beef
Heat a pan over medium-high. Cook marinated beef in batches (about 3-4) until cooked through, 3–5 min. (2*)
3. Make Compound Mayo
Mix mayo, thyme, and scallions. Spread on sourdough.
4. Assemble & Grill:
Heat pan on low. Place bread mayo-side down. Layer half mozzarella, 2 TBSP cheddar, bulgogi, remaining mozzarella, and top with bread. Flip every 2 min until cheese melts and crust is crispy (12–16 min).
5. Rest
Let sandwich rest on wire rack 1–2 min. Slice and enjoy.
Tips*
- Freeze ribeye 1.5–2 hr before slicing for cleaner cuts.
- Optional: sprinkle up to 1 tsp sugar per batch while cooking.
