Grilled Gorgonzola Flat Irons

Step 1
Preheat an oven to 400 degrees F (200 degrees C). Preheat an outdoor grill for medium-high heat, and lightly oil the grate.

Step 2
Combine the cinnamon, black pepper, garlic powder, chili powder, cayenne pepper, and brown sugar in a small bowl. Sprinkle over the flat iron steaks on all sides, and press into the meat; set aside.

Step 3
Heat the olive oil in a skillet over medium heat. Stir in the garlic and onion; cook and stir until the onion has softened and turned translucent, about 5 minutes. Pour in the red wine, and boil until the wine has nearly evaporated, about 5 minutes more. Remove the onions from the skillet and set aside.

Step 4
Cook the flat iron steaks on the preheated grill for 4 minutes per side, then remove and place into the skillet. Top the steaks with the onion mixture, and sprinkle with Gorgonzola cheese.

Step 5
Bake in the preheated oven until the cheese has melted and the steaks have cooked to your desired degree of doneness, about 5 minutes for medium. Sprinkle with chopped basil to serve.
