Elevate your sandwich game with juicy rump steaks topped with a vibrant, zesty chimichurri sauce. Served in toasted ciabatta with smoky chipotle mayo and a side of crispy Cajun-spiced fries, this recipe brings gourmet gastropub flavors right to your kitchen.
Preheat your oven to its highest setting. Pour the sunflower oil into a large baking tray and place it in the oven for 15 minutes to get shimmering hot. Carefully reduce the oven temperature to 220°C (200°C fan/gas 8). Tip the frozen fries into the hot oil, tossing them to ensure an even coat. Bake for 20 minutes, then sprinkle over the Cajun spice mix and bake for a final 15 minutes until the fries are golden and crisp.
While the fries are baking, prepare the chipotle mayo. In a small bowl, whisk together the mayonnaise, chipotle paste, and the lime zest and juice until well combined. Set aside in the refrigerator until ready to serve.
To make the chimichurri-style sauce, place the chopped shallot, red chilli, garlic, sherry vinegar, parsley, coriander, and extra-virgin olive oil into a food processor or blender. Blitz until you achieve a smooth consistency, then season with salt and pepper to taste. Set aside.
Heat a griddle pan over high heat until smoking. Season the rump steaks generously with salt only (avoid pepper at this stage as it can burn and turn bitter). Place the steaks in the pan and sear for 3 minutes on each side for a perfect medium finish. Transfer the steaks to a plate, cover loosely with foil, and allow them to rest for 10 minutes.
Halve the ciabatta rolls and toast them cut-side down in the same griddle pan used for the steaks to soak up the juices. Spread the bottom halves with a generous layer of chipotle mayo. Thinly slice the rested steak against the grain and divide the strips between the rolls. Drizzle with the fresh chimichurri sauce and top with a handful of rocket. Serve immediately with the spicy fries and any remaining mayo for dipping.
For the best flavor, ensure your steaks are at room temperature before cooking. If you don't have a food processor for the chimichurri, you can finely mince the herbs and aromatics by hand for a more rustic, chunky texture. To make it even faster, you can use store-bought chimichurri, but fresh is always superior!
