Instructions
Marinade Preparation: Craft a robust teriyaki sauce and immerse the flank steak completely, allowing flavors to penetrate deeply. Refrigerate for optimal marination.
Rice Foundation: Heat cooking oil in a skillet, toast rice until slightly golden, then integrate soy sauce, brown sugar, white sugar, grated ginger, and red pepper flakes. Stir thoroughly to create a fragrant base.
Vegetable Integration: Fold steamed vegetables into the seasoned rice, ensuring even distribution of textures and flavors.
Protein Searing: Extract marinated steak from refrigerator, slice into thin strips, and caramelize in a blazing hot skillet until edges develop a rich, crisp exterior.
Egg Accent: Whisk egg in a separate pan, cook until set, then slice into delicate pieces.
Casserole Assembly: Transfer rice-vegetable mixture and seared steak into a baking dish. Scatter egg pieces across the surface and drizzle with additional teriyaki sauce.
Oven Transformation: Preheat oven to 350°F (175°C). Bake casserole until top achieves a golden, slightly crisp appearance, approximately 20-25 minutes.
Serving Finale: Remove from oven and garnish with an extra teriyaki sauce drizzle for enhanced flavor complexity. Serve immediately while piping hot.
Notes
Marinate with Care: Allow steak to soak in teriyaki sauce for at least 2-4 hours to maximize flavor absorption and tenderize the meat.
Prevent Rice Clumping: Rinse rice before cooking and use a fork to fluff, ensuring separate, fluffy grains that mix perfectly with other ingredients.
Sear for Flavor Lock: Use high heat when cooking steak strips to create a caramelized exterior that seals in moisture and intensifies beef’s natural taste.
Temperature Timing: Let casserole rest 5-10 minutes after baking to allow flavors to settle and make serving easier without falling apart.
