To begin, prepare the chimichurri sauce. In a mixing bowl, combine finely chopped parsley, minced garlic, olive oil, red wine vinegar, dried oregano, chili flakes (if using), salt, and black pepper. Mix thoroughly until emulsified. Adjust salt and acidity to taste. Cover and let sit at room temperature for at least 20 minutes to allow the flavours to meld.

Preheat your grill to medium heat. If you don’t have a grill, you can use a stovetop grill pan or preheat your oven’s broiler. While the grill heats, use a fork to prick the chorizo sausages in a few spots. This helps release excess fat during cooking and prevents the casing from bursting.

Place the chorizo sausages on the preheated grill. Cook them for about 12–15 minutes, turning occasionally, until they are evenly browned and fully cooked through. The internal temperature should reach 70°C (160°F). For extra smoky flavour, you can grill over charcoal.

While the sausages cook, prepare the bread. Slice the baguette style rolls or ciabatta in half lengthwise but not all the way through, keeping the halves attached. For a traditional touch, lightly toast the bread on the grill for 1–2 minutes until golden and slightly crisp.

Once the chorizos are cooked, remove them from the grill and let them rest for 3–5 minutes. This allows the juices to redistribute, ensuring a tender and juicy sausage. During this time, you can brush the inside of the toasted bread with a light layer of chimichurri sauce for added flavour.

Slice the chorizo sausages lengthwise, creating two halves per sausage. This ensures an even distribution in the sandwich and makes it easier to eat. You can leave the sausages whole if preferred for a more rustic presentation.

Assemble the sandwiches by placing the sliced chorizo inside the prepared bread. Generously drizzle or spread additional chimichurri sauce over the sausage, allowing the vibrant flavours to soak into the bread. Adjust the amount of sauce based on personal preference.

Serve the choripán immediately, accompanied by extra chimichurri sauce on the side. Pair with a fresh salad, crispy fries, or simply enjoy it as is for an authentic experience. For a traditional Argentine touch, serve with a glass of Malbec or a refreshing soda. Present the sandwiches on a wooden board for a rustic, inviting look.
