Begin by preparing the chimichurri sauce. In a mixing bowl, combine parsley, garlic, red chili, olive oil, red wine vinegar, oregano, sea salt, and black pepper. Stir well until emulsified. Cover the bowl and let the sauce rest for at least 30 minutes to allow the flavours to meld while you prepare the steak.

Season the sirloin steaks generously on both sides with coarse sea salt and freshly ground black pepper. For an extra kick, sprinkle smoked paprika lightly over the steaks. Pat the seasonings into the meat to ensure an even coating. Let the steaks sit at room temperature for 15–20 minutes to ensure even cooking.

Preheat your grill or grill pan over medium-high heat. Brush the grill grates or pan lightly with olive oil to prevent sticking. Alternatively, preheat an oven to 200°C (390°F) if finishing the steaks in the oven for a perfect sear.

Once the grill is hot, place the steaks on the grates and cook for 3–4 minutes on one side without moving them, allowing a nice crust to develop. Turn the steaks over and cook for an additional 3–4 minutes for medium-rare, adjusting the time slightly for desired doneness.

If using the oven, transfer the steaks to a baking tray after searing. Finish cooking in the oven for 5–7 minutes to your preferred doneness. Use a meat thermometer for accuracy: 55°C (130°F) for medium-rare, 60°C (140°F) for medium.

While the steaks rest, prepare the grilled vegetables. Brush zucchini, bell peppers, or onions with olive oil, sprinkle with salt, and grill them for 3–4 minutes on each side until tender and slightly charred.

Rest the cooked steaks on a cutting board for 5–7 minutes to retain their juices. Slice the steaks against the grain into thick slices if serving family style or leave whole for individual plating.

Serve the Bife de Chorizo alongside the grilled vegetables and crusty bread or roasted potatoes. Generously spoon chimichurri sauce over the steaks for a bold, fresh flavour. Garnish with additional parsley or a wedge of lemon for a vibrant finish. Pair with a robust Argentinian Malbec for an authentic dining experience.
