Cut the steak into 1-inch cubes and season generously with salt and pepper.

Heat olive oil in a large skillet over medium-high heat. Add steak bites in a single layer and sear for 2-3 minutes per side until browned.

Reduce heat to medium-low; add butter and minced garlic. Stir until the butter melts and coats the steak.

Cook for an additional minute until fragrant. Remove from heat and sprinkle with parsley before serving.
