Start by preparing your rice according to the package directions. I like jasmine because it’s aromatic and light. While the rice cooks, you can move on to making the beef mixture.
Heat your skillet over medium-high and add the ground beef. Break it up as it cooks and ensure it's fully browned (about 8–10 minutes). If you use slightly fattier meat, drain off any excess fat.
Once the beef is browned, remove the pan from the heat momentarily and stir in the brown sugar, hoisin sauce, soy sauce, Sriracha, ginger, and garlic. Mixing off-heat helps distribute flavors evenly.
Put the pan back on medium heat and add the chopped red bell pepper. Cook for a few more minutes until the pepper is just tender-crisp. This keeps some bite and color contrast.
Once done, serve the beef over the cooked rice and garnish with scallions or sesame seeds if you like.
