Heat a skillet over medium heat and add the ground beef. Break up the ground beef as it starts to cook.
Once the beef is starting to brown a bit, add the pepper and onion to the skillet and continue cooking, stirring often, until the beef is cooked through and the vegetables have softened. Drain off any excess fat from the beef.
Add the Korean BBQ sauce to the skillet and stir to coat the beef. Cook for 5 minutes to thicken the sauce a bit, stirring occasionally.
While the beef cooks in the sauce, butter the buns and toast them on a hot skillet until golden brown.
Remove the beef from the heat and stir in the green onions. Alternately, save the green onions for sprinkling on top of the beef once you’ve spooned it on the buns.
Spoon the beef onto the toasted buns and serve hot.
Notes
Korean BBQ Sauce: We’re pretty into our homemade Korean BBQ sauce - it’s the perfect balance of sweet and savory. Highly recommend giving it a try, although a store bought sauce will likely work just fine. Toppings: Every now and then I’ll slice up some cucumbers to throw on top of this, but they do tend to get warm from the heat of the beef and buns which isn’t my favorite. Usually we serve my Asian cucumber salad on the side. Something about Korean beef + fresh, crisp cucumbers just makes a great combo.Buns: I’m a sucker for buttery brioche buns, but your standard sesame seed bun will work just fine too!
