Ground beef kebabs can be made in the oven or on the stove. Preheat your oven to 350ºF and bake on a greased baking sheet for 15 to 20 minutes until cooked through to at least 160ºF. Or, use a grill pan over medium-high heat, and grill on each side until browned and cooked through. If you don't own a grill pan, cook the kofta without skewers in a pan.
