Cook your rice according to the package instructions. Set aside once cooked.
In a large skillet or wok over medium-high heat, add the lean ground beef. Cook for about 5-7 minutes, breaking it up as it cooks, until browned and cooked through.
Add the minced garlic to the skillet and cook for an additional minute until fragrant. Stir in the brown sugar, soy sauce, sesame oil, ground ginger, crushed red pepper flakes, and pepper. Mix until well combined.
Allow the mixture to simmer for about 3-5 minutes, stirring occasionally, until the flavors meld and the sauce thickens slightly.
To serve, place a scoop of hot cooked rice in each bowl and top with the Korean ground beef mixture.
Garnish with sliced green onions and a sprinkle of sesame seeds. Enjoy your Korean Ground Beef and Rice Bowls hot!
