Step‑by‑Step Instructions for Argentinian Stuffed Flank Steak
Step 1: Prepare the Grill
Preheat your grill to medium direct heat, aiming for around 400°F (204°C). This temperature ensures a beautifully seared exterior while allowing the inside of your Argentinian Stuffed Flank Steak to reach the perfect doneness. Make sure the grill grates are clean to enhance the flavor and prevent sticking.
Step 2: Butterfly the Steak
Using a sharp knife, carefully butterfly the flank steak by slicing it horizontally, creating a pocket for your stuffing. Once opened, gently pound the steak to an even thickness of about half an inch. This helps with cooking consistency and tenderizes the meat, ensuring a delightful bite in every slice.
Step 3: Mix the Herb Marinade
In a medium bowl, combine olive oil, minced garlic, cilantro, parsley, salt, black pepper, and red pepper flakes. Stir until well blended, and the mixture becomes fragrant. This herb marinade will invigorate your Argentinian Stuffed Flank Steak, enhancing its natural flavors as it cooks, so spread it evenly across the surface of the opened steak.
Step 4: Add the Stuffing
Once the herb mixture is spread evenly, layer quartered hard-boiled eggs and sliced bell peppers directly on top. Make sure to distribute them evenly to ensure each slice holds a hearty filling. The vibrant colors of the peppers add not just flavor, but also a vibrant visual appeal to your stuffed steak.
Step 5: Roll the Flank Steak
Starting from the left side, carefully roll the flank steak like a jelly roll, compacting the filling as you go. Once rolled tightly, secure it with butcher’s twine at equal intervals to keep the stuffing contained during grilling. Tying the steak makes it easier to handle and cook uniformly, resulting in a mouthwatering finished product.
Step 6: Season the Outside
Generously season the exterior of the rolled steak with salt and pepper, allowing the flavors to penetrate during grilling. This step not only enhances the taste of your Argentinian Stuffed Flank Steak but also creates a beautiful crust that complements the stuffing. Make sure there’s an even coating for the best results.
Step 7: Grill the Steak
Place the stuffed, tied flank steak on the preheated grill. Grill for about 4-5 minutes on each side, aiming for a total cook time of approximately 20 minutes. You’re looking for a nice char and an internal temperature of 130°F (54°C) for perfect medium-rare. Keep an eye on it to avoid overcooking the meat.
Step 8: Allow to Rest
Once cooked, remove the Argentinian Stuffed Flank Steak from the grill and let it rest for about 15 minutes. This resting period allows juices to redistribute throughout the meat, ensuring every slice remains juicy and flavorful. Don’t skip this step; it’s essential for achieving that perfect texture.
Step 9: Slice and Serve
After resting, carefully slice the steak into even portions, showcasing the colorful filling as you cut. Each slice should reveal the vibrant mix of hard-boiled eggs and bell peppers. Serve warm, and consider pairing it with a side of chimichurri sauce to enhance the experience of this delightful Argentinian dish.
