A beef Florentine roast makes an impressive main course for a dinner party when you slice it to reveal the filling in a pinwheel shape. Although "Florentine" can refer to the cooking style in Florence, Italy, Florentine-style usually means a food is cooked with spinach and, in many cases, an Italian cheese. You can make a beef Florentine roast from any boneless beef roast, such as a beef tenderloin, an eye of round roast, rump roast or sirloin roast.
Trim the excess fat from the outside of the roast with a boning knife.
Butterfly the roast so it's flat and lays open, which basically involves cutting the roast in a spiral. Moving your knife parallel to the cutting board, slice into the roast almost all the way across, stopping about 1/2 inch to 1 inch before cutting all the way through. Open up the two halves like a book. You might need to pound the roast a bit with a meat mallet to make it lay flat when finished.
Cover the meat with a layer of fresh spinach leaves. Drizzle olive oil lightly over the spinach, and add your choice of spices, such as salt, black pepper and Italian seasonings like basil and oregano. Top the spinach with a thin layer of your choice of cheese, if desired, like provolone, Parmesan, Asiago, mozzarella or a blend of cheeses.
Roll up the meat with the spinach and cheese inside, starting from one long edge and working to the opposite edge, like you would roll up a carpet.
Tie up the roast with butcher's twine to keep it from unrolling, starting about 1 inch from the end and continuing every 2 inches. You can cut individual lengths of twine, if desired, or tie the roast with a continuous length of string. After tying the first loop, make a large loop in your hand, slide it under the roast and position it 2 inches down from the first tie. Pull the string tight, make a second loop, slide it under and pull it tight to make a third tie, repeating this process down to about 1 inch from the opposite end.
Place the roast in a baking dish. Sprinkle salt and pepper over the outside of the roast. You can also drizzle olive oil over the roast and sprinkle an Italian seasoning blend over top. Preheat the oven to about 350 to 400 degrees Fahrenheit.
Bake the roast for about 15 to 20 minutes per pound, or until the beef reaches the desired internal temperature. Choose a lower temperature and longer cooking time tough cuts of beef such as chuck roasts, and a higher, faster cooking method for lean, tender cuts such as tenderloin. Use a meat thermometer to determine doneness. Remove the roast at 120 F for rare, 125 F for medium-rare, 130 F for medium, 135 F for medium-well or 140 F for well done roasts. The cooking time for a rare roast might not be enough to cook the spinach through.
Remove the beef florentine roast from the pan, and let it rest for at least 3 minutes. Slice the roast into pinwheels for individual servings. Use the strings as a guide, cutting at the center between two strings. Remove and discard the strings.
- Butchers typically tie roasts with a butcher's knot. When you gather the two ends, instead of wrapping the string just once, wrap the short end two or three times around the long end of string.
