Here is a fantastic recipe using flank steak. The flank steak pinwheels or Italian Stuffed London Broil produces an amazingly tender stuffed steak. Inside the roll is thinly sliced prosciutto and ooey gooey provolone cheese. I know you are going to love it!
The flavors of this Italian Stuffed London Broil are so complex. First, the marinade starts to add flavor to the beef. Then the ingredients for the stuffing are added to the dish. Finally, the grill works its magic, searing the meat with a nice char on the outside, then slowly cooking it to mouthwatering perfection!

How to prepare Italian Stuffed London broil
You want to start at least 2 1/2 hours before you are planning to serve. It is really important to take the time to marinate and cook your London broil properly!
Before your meat goes into the marinade, you need to butterfly the steak. Lay the steak out on a cutting board. Using a sharp boning knife or other thin-bladed knife, slice the meat horizontally on the long side of the steak.
Do not cut all the way through; leave about 1/2 an inch uncut. The idea is that you want to be able to open the steak like a book.
Open the steak so it lays flat, and using a meat mallet, pound the steak to a uniform thickness. You want it to be about 1/2 an inch thick. Now it’s time for the marinade.
Prepare the marinade by combining all the ingredients together in a large bowl or large flat-bottom dish. Whisk to ensure that everything is well mixed.
Place the steak into the marinade and turn it over a few times to make sure that it is well coated. Cover the bowl or dish with plastic wrap and place in the refrigerator for 2 hours.
Preparing your Italian Stuffed London Broil for the grill
Start by setting up your grill to cook your Italian-stuffed London Broil. Heat one side of your grill to medium hot, about 425 degrees F. and leave the other side cool. You are going to sear the outside of the London broil and then slow-cook it on the cool side of the grill to finish it.
Remove the steak from the marinade and lay it on a large cutting board. Reserve the marinade, don’t throw it out!
Spread the pesto evenly over the entire surface of the flank steak, leaving about 1/2 inch uncovered around the outside of the steak. Next, lay the prosciutti slices evenly over the pesto sauce. Finally, layer the provolone cheese slices on top of the prosciutto. I usually put on a few grinds of fresh ground pepper on the provolone.
Roll up the steak like a jelly roll, making sure that the grain of the meat runs the length of the roll. Using kitchen twine, tie the roll tightly about every 1 1/2 inches. If you like, you can smear the outside of the roll with additional pesto.
grilling your Italian stuffed London Broil
Place the roll on the hot side of the preheated grill and sear well on all sides. Then move the roll to the cooler side of the grill and close the lid. Reduce the heat so that the temperature of the grill with the lid closed settles at about 375 degrees F.
Continue to cook the flank steak roll using the indirect method for about 30 – 40 minutes. To keep the roast moist and to add flavor, use the marinade to baste the roll every 10 minutes or so while cooking.
Continue to cook the flank steak roll until the internal temperature reaches 130 degrees F when tested with an instant-read thermometer.

I always use my trusty Thermapen One instant-read thermometer for an accurate and quick read of internal temperature.
Once your roll has reached the desired internal temperature, remove it from the grill and allow it to rest for 10 minutes or so.
You want all the juices from the meat to be reabsorbed into the roast before you slice it. If you cut it right away after removing it from the grill, you will lose most of the juice and much of the flavor of the meat!
Serving your Italian Stuffed London Broil
Now it’s time to serve up your excellent stuffed flank steak! Cut the roll into slices about an inch and a half thick. I usually try to cut between the kitchen twine so that all the slices are about the same size.
Don’t forget to remove the kitchen twine before serving it to your family or guests. After all, there is nothing worse than getting a piece of meat still tied with kitchen twine!
Look at how wonderful that slice of Italian Stuffed London Broil looks! Cooked to a perfect medium rare, with the thinly sliced prosciutto and melted provolone cheese in the middle. Serve it with your choice of grilled or roasted vegetables; it really is an amazingly elegant dinner that is simple to prepare!
