Prepare all ingredients "mise en place" (measured, cut, grated, before starting to cook).
Heat the sesame oil in a large skillet over medium-high heat. Add ground beef and brown it for 6 minutes.
Add the garlic, ginger, hoisin sauce, gochujang, brown sugar, soy sauce, rice vinegar, and the scallion whites. Stir and cook for 5 minutes.
Add the carrots and cook for 2 minutes.
Add sriracha to taste, if you want it more spicy.
Serve over white rice, with sliced scallion greens and sesame seeds sprinkled on top.
