Ingredients
1½ pounds flank steak
Salt and black pepper to taste
1 tablespoon olive oil
2 tablespoons butter
3 cloves garlic, minced
1 tablespoon fresh parsley, chopped (optional)
Optional sides: roasted potatoes, salad, rice, or veggies
Instructions
Let flank steak come to room temperature for 15–20 minutes. Pat dry and season both sides generously with salt and pepper.
Heat olive oil in a cast iron skillet over medium-high heat until very hot.
Add steak and sear for 4–5 minutes per side for medium-rare (adjust time based on thickness and desired doneness).
Reduce heat to low. Add butter and garlic to the pan. Spoon the melted garlic butter over the steak for 1–2 minutes.
Remove steak from the pan and let rest for 5 minutes. Slice thinly against the grain.
Drizzle remaining garlic butter from the pan over sliced steak and top with fresh parsley if using.
