Flank Steak Florentine
Recipe: Flank Steak Florentine


  • 1 3/4 - 2 pound flank steak
  • 1 clove garlic, cut in half plus 1 teaspoon minced garlic
  • 4 tablespoons extra virgin olive oil
  • 2 tablespoons balsamic vinegar
  • 1 (1 pound) bag frozen spinach, thawed
  • 1 large egg, beaten
  • 1 tablespoon finely chopped fresh rosemary
  • 1/2 small red bell pepper, seeds and membranes removed, cut into small dice (1/4 cup)
  • 1/2 cup dry bread crumbs, panko preferred
  • 1 1/2 cups packed freshly grated Italian cheese, such as Asiago, Parmesan, Pecorino, or mozzarella
  • Kitchen twine as needed
  • 2 tablespoons canola or grape seed oil oil


  1. Butterfly steak (see above notes). Rub both sides with cut garlic and season with kosher salt and freshly ground pepper.
  2. Make a marinade by whisking together oil and vinegar. In a zip-lock bag or container large enough to accommodate steak, let meat marinate in vinaigrette at least two hours and up to six, refrigerated, turning once.
  3. Preheat oven to 400 degrees.
  4. Remove water from spinach by pressing it into a sieve with a spoon, then wringing out all remaining water with fists or clean towels. Combine with minced garlic, egg, rosemary, bell pepper, bread crumbs, 1/2 teaspoon kosher salt and 1/2 teaspoon freshly ground pepper.
  5. On a flat surface, lay out butterflied flank steak and spread out so the grain is running in front of you, left to right. Evenly press spinach mixture into entire flank steak. Sprinkle and press cheese mixture into spinach mixture, then tightly roll up, jelly-roll style, into a log.
  6. Cut a long piece of twine. First, wrap around the length of beef then wrap around the roll, securing it every couple of inches. Knot the twine and cut off dangling ends.
  7. In a large, heavy-bottomed skillet, heat oil over high heat. Sear flank steak on all sides, about 5 minutes total cooking time. Place flank steak on foil or parchment-lined cooking sheet and roast on center rack of oven 25-30 minutes, or until cooking thermometer registers 135 degrees, for rare and medium rare pieces.
  8. Remove to a cutting board with a well, and tent with foil. Let rest 15 minutes. Remove foil and, with a sharp knife, cut into 3/4-inch pieces. Remove twine and serve.

Number of servings (yield): 6 (12-14 pinwheels)

Marinate Time: 2-6 hours

Active Time: 40 minutes
