Description
A quick and easy weeknight dinner featuring tender flank steak seared in a skillet and basted with a rich garlic butter sauce. Ready in under 20 minutes with simple ingredients.
Ingredients
Scale
- 1.5 to 2 lbs flank steak
- 2 tablespoons soy sauce (or tamari for gluten-free)
- 1 teaspoon Worcestershire sauce
- 1 tablespoon brown sugar
- 3 cloves garlic, minced (for marinade)
- 1 teaspoon black pepper
- 1 tablespoon high smoke point oil (avocado or canola)
- 4 tablespoons unsalted butter
- 4 cloves garlic, thinly sliced or minced (for baste)
- 2–3 sprigs fresh thyme
- Pinch of red pepper flakes (optional)
Instructions
- Whisk together soy sauce, Worcestershire sauce, brown sugar, minced garlic, and black pepper in a small bowl.
- Place flank steak in a zip-top bag or shallow dish, pour marinade over it, and refrigerate for at least 30 minutes (up to 4 hours).
- Remove steak from fridge and let sit for 15 minutes to come to room temperature. Pat dry with paper towels.
- Heat cast iron skillet over medium-high heat with oil until slightly smoking.
- Sear steak in the hot skillet for 3-4 minutes without moving it to form a crust.
- Flip steak and cook for another 3-4 minutes until internal temperature reaches 130°F (medium-rare) or 140°F (medium).
- Reduce heat to medium. Add butter, sliced garlic, thyme, and red pepper flakes to the pan.
- Tilt pan and baste steak with the melted garlic butter for 1-2 minutes.
- Remove steak from pan and let rest on a cutting board, tented with foil, for 5-10 minutes.
- Slice steak against the grain and serve with pan juices.
Notes
Always slice the steak against the grain to ensure tenderness. Do not overcook flank steak as it is a lean cut; medium-rare to medium is ideal. Let the steak rest before slicing to retain juices. If using salted butter, reduce added salt in the marinade.
