Ingredients
Scale
Steak and Seasoning
- 1½ pounds flank steak
- 2 tablespoons olive oil
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon smoked paprika
- 1 teaspoon garlic powder
Garlic Butter
- 4 tablespoons unsalted butter, softened
- 3 cloves garlic, minced
- 1 tablespoon fresh parsley, chopped
- 1 teaspoon fresh rosemary or thyme (optional)
- 1 teaspoon lemon juice (optional, for brightness)
Instructions
- Preheat and Prepare Steak: Preheat the oven to 400°F (200°C). Pat the flank steak dry with paper towels to ensure a good sear. In a small bowl, mix together salt, black pepper, smoked paprika, and garlic powder. Rub this spice blend evenly over both sides of the steak.
- Sear the Steak: Heat a large oven-safe skillet, preferably cast iron, over medium-high heat. Add olive oil and allow it to heat until shimmering. Place the steak in the skillet and sear for 2–3 minutes on each side until a golden-brown crust forms.
- Roast the Steak: Transfer the skillet with the steak into the preheated oven. Roast for 5–7 minutes, depending on your preferred level of doneness: 130°F internal temperature for medium-rare or 140°F for medium.
- Prepare Garlic Butter: While the steak roasts, combine the softened butter, minced garlic, chopped parsley, fresh rosemary or thyme if using, and lemon juice in a small bowl. Mix well to create the garlic butter blend.
- Rest and Serve: Remove the skillet from the oven. Immediately top the steak with the garlic butter, letting it melt over the meat. Tent the steak loosely with foil and allow it to rest for 5–10 minutes to retain juices. Thinly slice the steak against the grain. Spoon any remaining garlic butter from the skillet over the sliced steak before serving.
Notes
- Flank steak cooks quickly—avoid overcooking for optimal tenderness.
- Pairs well with roasted vegetables, mashed potatoes, or a fresh green salad.
- Leftover steak is excellent for sandwiches or wraps.
