Heat a large cast iron skillet over medium heat. Add olive oil and ghee, allowing it to melt and coat the pan.

Add cubed Yukon Gold potatoes, minced garlic, fresh thyme, oregano, salt, and pepper. Cook for 8-10 minutes until golden brown and tender.

Transfer potatoes to a plate. Increase heat to medium-high and add remaining ghee. Add steak cubes and sear without disturbance for 2 minutes.

Continue cooking steak, stirring occasionally, until desired doneness, about 3-4 minutes more.

Return potatoes to skillet, stir gently to combine, and cook for another minute. Garnish with freshly chopped parsley.
