Marinade and Sauce
- 3/4 cup low-sodium soy sauce
- 1/2 cup water
- 1/4 cup brown sugar
- 1/2 teaspoon garlic powder
- 1/2 teaspoon sesame oil
Steak
Thickening Agent
- 2 tablespoons cornstarch
- 2 tablespoons water
Other Ingredients
- 1 tablespoon canola oil
- 3 cups cooked rice
- 3 cups mixed leftover or frozen vegetables (broccoli, carrots, baby corn, cauliflower), cut into bite-sized pieces
- 1 scallion, thinly sliced
- 1 tablespoon sesame seeds
- Preheat and Prepare Steak: Preheat the oven to 350°F (175°C). Slice the flank steak against the grain into bite-sized pieces to ensure tenderness.
- Make Marinade and Marinate Steak: In a medium bowl, combine soy sauce, water, brown sugar, garlic powder, and sesame oil. Add the steak pieces, making sure each piece is well coated. Marinate for a minimum of 30 minutes and up to 6 hours for deeper flavor.
- Prepare Cornstarch Slurry: Whisk together cornstarch and water in a small bowl until smooth. Set aside; this will thicken the sauce later.
- Sear the Steak: Heat canola oil in an oven-safe large skillet over high heat. Remove steak from marinade, reserving the marinade. Quickly sear the steak in the hot pan for about 1 minute per side until browned but not fully cooked.
- Create the Teriyaki Sauce: Pour the reserved marinade into the skillet with the steak and bring to a boil. Then reduce heat to low and whisk in the cornstarch slurry, cooking until the sauce thickens to a syrupy consistency, about 2–3 minutes.
- Combine Rice and Vegetables: Add the cooked rice to the skillet and toss well to coat it evenly with the sauce. Stir in the mixed vegetables and gently combine everything.
- Bake the Casserole: Transfer the skillet to the preheated oven and bake uncovered for 15 minutes to allow flavors to meld and vegetables to warm through.
- Broil Steak for Crispness: After baking, remove the skillet from the oven, scatter the seared steak pieces over the casserole, and place under the broiler for an additional 5 minutes to crisp up the steak edges.
- Garnish and Serve: Remove from oven, sprinkle the casserole with thinly sliced scallions and sesame seeds, then serve hot.
Notes
- Slice the steak against the grain to ensure maximum tenderness.
- You can use any leftover or frozen mixed vegetables as preferred.
- Adjust marinating time based on schedule, but at least 30 minutes is essential for flavor.
- If you prefer, substitute cooked quinoa or cauliflower rice for a lower-carb option.
- Make sure the skillet you use is oven-safe to facilitate both stove-top and oven cooking.
- For a gluten-free option, use tamari or gluten-free soy sauce.
- Broiling at the end is key for enhancing texture on the steak pieces; watch carefully to prevent burning.
