1 flank steak (about 1 3/4 pound)
3 tablespoons extra-virgin olive oil
2 tablespoons sweet paprika
2 tablespoon light brown sugar
1 tablespoons kosher salt
2 teaspoons chili powder
1 lime, zested
Preheat a broiler to high. Bring the steaks to room temperature
about 20 minutes before cooking.
Mix the olive oil, paprika, sugar, chili powder, salt, chili powder,
and zest in a bowl to make a paste. Rub the spice mixture all over
the steak. Broil until just charred and crispy on top, about 6 minutes
on 1 side. Flip the steak and cook until beginning to char, about
6 minutes more or until rare and temperature registers 115F on an
instant-read thermometer. Place the steak on a cutting board and let
rest, tented with foil for about 10 minutes. Slice across the grain
and serve.
