Flat Iron Steak with Three Pepper Rub

1 tablespoon smoked paprika

2 teaspoons salt

1 teaspoon brown sugar

2 teaspoons chili powder

1 teaspoon chipotle chile powder

½ teaspoon ground black pepper

½ teaspoon garlic powder

½ teaspoon onion powder

½ teaspoon ground cumin

2 pounds flat iron steaks

Stir together the paprika, salt, sugar, chili powder, chipotle powder, black pepper, garlic powder, onion powder, and cumin in a small bowl until blended. Rub the seasoning mix all over the flat iron steaks, then wrap them tightly with plastic wrap. Marinate in the refrigerator 2 to 8 hours (the longer the better).

Preheat an outdoor grill for medium-high heat, and lightly oil grate.

Cook the steaks on the preheated grill until cooked to your desired degree of doneness, about 4 minutes per side for medium. Allow the steaks to rest for 5 minutes in a warm location before slicing.
