Step‑by‑Step Instructions for Korean Steak Sandwich
Step 1: Prep Steak
Start by placing the ribeye steak in the freezer for about 30 minutes until it’s slightly firm. This will make it easier to slice it thinly, about 2mm thick. Once firm, remove the steak and use a sharp knife to cut it against the grain into thin strips, ensuring tenderness in your Korean Steak Sandwich.
Step 2: Marinate Steak
In a bowl, combine soy sauce, gochujang paste, minced ginger, light brown sugar, rice wine, minced garlic, black pepper, grated apple, and toasted sesame oil. Whisk until fully integrated. Add the sliced steak to the marinade, making sure it’s well coated. Let it marinate for at least 30 minutes to absorb those delicious flavors before cooking.
Step 3: Cook Steak
Heat a skillet over high heat and add a drizzle of neutral oil to prevent sticking. Once hot, add the marinated steak in a single layer, allowing it to sear without overcrowding the pan. Cook for about 4-5 minutes, stirring occasionally, until the steak is caramelized and browned. Drain any excess liquid if necessary, ensuring a juicy yet savory outcome.
Step 4: Cook Peppers
In the same skillet, reduce the heat slightly and add sliced bell peppers. Sauté for 2-3 minutes until vibrant and slightly softened, maintaining their crispness and color. Stir occasionally to prevent burning and to help release the natural sweetness, making them the perfect complement to your Korean Steak Sandwich.
Step 5: Prepare Bread
Take thick slices of bread and brush one side of each slice with salted butter, ensuring an even coating. Layer the sandwich by placing the cooked steak, sautéed peppers, sesame seeds, shredded mature cheddar cheese, slices of red onion, jalapenos, and chopped scallions between two slices of bread, buttered side out, creating a hearty filling.
Step 6: Grill Sandwiches
Heat a non-stick skillet over low-medium heat. Carefully place the assembled sandwiches in the skillet, cooking for 2-3 minutes per side. Press down slightly with a spatula, allowing the cheese to melt and the bread to turn golden brown. You’ll know it’s ready when the outside is crispy and the cheese is melting inside.
Step 7: Make Sauce and Serve
While the sandwiches are grilling, prepare the garlic mayo by mixing mayonnaise with minced garlic in a small bowl. Drizzle this savory sauce inside each sandwich just before serving. Cut the Korean Steak Sandwich in half to reveal the gooey interior and serve it immediately for a delicious meal that everyone will love.

Make Ahead Options
These Korean Steak Sandwiches are perfect for meal prep, allowing you to enjoy their delightful flavors even on the busiest days! You can marinate the ribeye steak up to 24 hours in advance, ensuring it absorbs all the savory goodness. Additionally, the sautéed bell peppers can be prepped and stored in the refrigerator for up to 3 days. When you’re ready to serve, simply assemble the sandwiches with the marinated and cooked steak, sautéed peppers, and the garlic mayo just before grilling. This way, you’ll enjoy restaurant-quality Korean Steak Sandwiches with minimal effort and maximum flavor!
