Marinate the steak: In a bowl, mix together soy sauce, brown sugar, sesame oil, minced garlic, grated ginger, rice vinegar, and optional gochujang. Place the steak in the marinade and toss until fully coated. Refrigerate for at least 15 to 30 minutes.
Prepare the spicy cream sauce: In a small bowl, combine mayonnaise, sriracha, lime juice, and honey. Stir until smooth and well-mixed.
Cook the steak: Heat a skillet over medium-high heat. Remove the steak from the marinade and place it in the hot skillet. Sear the steak for about 2-3 minutes per side, depending on your desired doneness. Once cooked, remove the steak from heat and let it rest for a few minutes.
Assemble the bowls: Start with cooked rice as your base. Layer on the cooked steak, then add shredded carrots and sliced cucumbers. If desired, include kimchi for extra flavor. Finish with sliced green onions and a sprinkle of sesame seeds. Drizzle the spicy cream sauce generously over the top.
Notes
Use fresh ingredients for the best flavor. Adjust the spice level in the cream sauce to your preference.
