Gather all ingredients: mince 4 cloves of garlic, chop parsley, and cube butter. Ensure skirt steak is trimmed and at room temperature.

Pat skirt steak dry with paper towels and season both sides with salt and pepper. Let sit for 5 minutes.

Heat a skillet over high heat and add a splash of oil. Sear skirt steak for 2-3 minutes on each side until browned. Remove and let rest.

Lower heat, add cubed butter, and let melt. Scrape flavorful bits from the skillet. Add minced garlic and cook for 1-2 minutes.

After resting, slice steak against the grain into thin strips. Arrange slices on a platter, drizzle with garlic butter, and garnish with parsley.
