Begin by preparing your ingredients: mince the garlic and cut the butter into cubes.

Pat the skirt steak dry with paper towels and season both sides generously with salt and pepper.

Heat oil in a skillet over high heat until shimmering, then add the seasoned skirt steak and sear for 2–3 minutes per side.

Remove steak from the skillet and let it rest for a few minutes.

In the same skillet, reduce heat to low, add butter, and stir in minced garlic for 1-2 minutes until fragrant.

Slice the rested steak against the grain, drizzle warm garlic butter over the top, and serve immediately.
