This recipe appears in:The Food Lab: How to Make Grilled Stuffed Flank Steak Pinwheels
Inspired by the classic New Orleans muffuletta sandwich, we roll a butterflied flank steak with prosciutto, capicola, mortadella, provolone, and a punchy olive salad, then slice it into colorful pinwheels that get grilled over a hot fire.
Why this recipe works:
- Butterflying the flank steak allows you to stuff it more easily. Butterflying with the grain ensures that the steak will be sliced against the grain into serving portions.
- Securing the rolled flank steak with a combination of butcher's twine and wooden skewers helps them hold together as they cook on the grill.
- We cook the steaks first over a hot fire to help the cheese and fillings build up a crust that will prevent them from leaking out when we then transfer the steaks to the cooler side of the grill to finish cooking, freeing up the hot side for vegetable sides.
Notes: This steak can also be prepared indoors. See Step 6 for pan-frying instructions.
- 1 whole flank steak, 2 to 2 1/2 pounds, trimmed of excess fat
- Kosher salt and freshly ground black pepper
- 1 cup New Orleans-Style Olive Salad
- 3 ounces thinly sliced prosciutto
- 3 ounces thinly sliced capicola
- 3 ounces thinly sliced mortadella
- 4 ounces thinly sliced Provolone cheese
Lay steak on a cutting board with grain running parallel to the edge of the counter. Trim left and right edges to form a clean rectangle and reserve scraps for another use. Hold steak flat with your non-knife hand and, with a sharp boning knife, carefully butterfly the steak, leaving the back edge attached by 1/2- to 1/4-inch of meat. Open up steak and flatten the seam gently with your hand to form a large perfect rectangle.
Season steak on exposed side with salt and pepper. Spread olive salad evenly over steak, leaving a 1-inch border at the top and the bottom. Layer prosciutto, capicola, mortadella, and Provolone over steak, leaving the border at the top and bottom.
Carefully roll the steak away from you (the grain should run width-wise), tightening as you go until it is rolled into a cylinder. Let it rest with its seam-side down.
Tie the beef tightly with twine, spacing the ties evenly every 1 1/2 inches. Insert a skewer through each piece of twine. Using a sharp knife, carefully cut between the ties to make the pinwheels. Season with salt and pepper.
Light one chimney full of charcoal. When all the charcoal is lit and covered with gray ash, pour out and spread the coals evenly over half of coal grate. Alternatively, set half the burners of a gas grill to high heat. Set cooking grate in place, cover gill and allow to preheat for 5 minutes. Clean and oil the grilling grate. Place the pinwheels on the hot side of the grill and cook without moving until well charred on first side, about 3 minutes. Flip steaks and char second side, about 3 minutes longer. Transfer to cooler side of grill, cover, and cook until an instant read thermometer inserted into the center registers 120°F for medium-rare or 130°F for medium. Transfer to a platter, let rest for five minutes, and serve.
Alternatively, to finish indoors: Heat 2 tablespoons vegetable or canola oil in a large stainless steel or cast iron skillet over high heat until shimmering. Add pinwheels and cook without moving until well browned on first side, about 3 minutes. Flip pinwheels and continue cooking until second side is browned and an instant read thermometer registers 120°F for medium-rare or 130°F for medium, reducing heat as necessary if steak smokes excessively or starts to burn. Transfer to a wire rack set in a rimmed baking sheet and allow to rest 5 to 10 minutes. Serve.
