Preheat your oven to 400°F.
Spread the cooked rice evenly on a large sheet pan.
In separate sections on the sheet pan, arrange the julienned carrots, zucchini, and sliced shiitake mushrooms. Drizzle soy sauce and sesame oil over the vegetables. Season with salt and pepper. Toss each vegetable section to coat them in the seasoning.
In a large bowl, mix soy sauce, sugar, sesame oil, minced garlic, and grated ginger. Add the thinly sliced beef to marinade in the sauce.
In another section on the sheet pan, lay out the thinly sliced beef and pour the sauce over the beef.
Place the sheet pan in the preheated oven and roast for about 15-20 minutes or until the vegetables are tender and the beef is cooked through. You can toss the vegetables and beef halfway through the cooking time for even cooking.
While the sheet pan is in the oven, fry eggs in a separate pan or on a griddle.
Once everything is cooked, remove the sheet pan from the oven.
Assemble in a bowl with the rice, roasted veggies, beef, fried egg and any other topping you'd like, such as gochujang on the side for those who enjoy extra spice.
