In a large skillet over medium heat, add the ground beef. Cook until browned, breaking it apart with a spatula, approximately 5-7 minutes. Drain excess fat if needed.
In a small bowl, whisk together the soy sauce, sesame oil, brown sugar, gochujang, minced garlic, and grated ginger. Pour the sauce over the browned beef, mixing well to combine. Allow to simmer for an additional 2-3 minutes, letting the flavors meld.
Stir in the chopped green onions and season with salt and pepper to taste.
In a separate pot or food steamer, add the spinach and steam for about 2 minutes until wilted. You can also sauté it briefly with a touch of oil if preferred.
To assemble the bowls, place a scoop of cooked rice at the bottom. Top with the sautéed beef mixture and a handful of spinach.
Garnish with sesame seeds and extra green onions for added flavor and color.
Notes
For a low-carb option, substitute jasmine rice with cauliflower rice.
