Cut the lamb or beef into bite-sized pieces. Season with salt, black pepper, ground cumin, and ground coriander. Mix well to coat the meat evenly with the spices.
In a large skillet or frying pan, heat the vegetable oil or lamb fat over medium-high heat.
Add the seasoned meat to the hot skillet. Fry until the meat is browned on all sides, about 5-7 minutes. Stir occasionally to ensure even cooking.
Add the thinly sliced onions and minced garlic to the skillet with the meat.
Continue to cook, stirring occasionally, until the onions are soft and golden brown, about 10-15 minutes.
Taste and adjust the seasoning with more salt and black pepper if needed.
Transfer the kovurma to a serving dish.
Garnish with fresh herbs such as parsley or cilantro.
Enjoy your meal!
