Gather all ingredients and equipment.

Cut the steak into bite-sized cubes, about one inch thick.

In a mixing bowl, season the steak cubes generously with salt and pepper.

Heat olive oil in a large skillet over medium-high heat until shimmering. Add the seasoned steak cubes and cook until golden brown, approximately 3-4 minutes per side.

Reduce heat to medium-low, then add minced garlic and butter to the skillet. Stir until well combined and fragrant.

Serve hot, drizzling any remaining garlic butter sauce over the steak bites.
