Ingredients

Sandwich

• 2 premium steaks
• 2 ciabatta rolls
• Fresh rocket

Caramelised Onions

• 2 medium brown onions, chopped
• 2 tablespoons brown sugar
• 2 tablespoons balsamic vinegar
• Pinch of sea salt and cracked black pepper

Roasted Garlic & Chive Aioli

• 75 ml olive oil
• 1 whole garlic bulb
• Sea salt
• ½ teaspoon Dijon mustard
• Bunch of fresh chives, finely chopped
• Light squeeze of half a lemon
• 1 egg yolk

Instructions

1. Remove the steaks from the fridge and allow them to sit at room temperature for 30 minutes. Season generously with sea salt and cracked black pepper.
   
   
2. Slice the garlic bulb in half, drizzle with olive oil, season lightly with salt, and wrap tightly in foil.
   
   
3. Preheat the BBQ grill. Place the steaks and wrapped garlic onto the grill.
   
   
4. Drizzle the ciabattas with olive oil and place them cut-side down on the grill until lightly toasted.
   
   
5. Cook the steak for 3–4 minutes per side for medium-rare, or 5–6 minutes per side for well done.
   
   
6. Meanwhile, sauté the chopped onions in a frying pan with a knob of butter over medium heat for 3–5 minutes until soft.
   
   
7. Reduce the heat, add the brown sugar and balsamic vinegar, and simmer for 1–2 minutes until thick and caramelised.
   
   
8. For the aioli, blend the egg yolk and Dijon mustard until pale and creamy, about 1 minute.
   
   
9. Slowly drizzle in the olive oil while blending to emulsify.
   
   
10. Add the chopped chives, lemon juice, and the roasted garlic squeezed from the bulb. Blend until smooth.
    
    
11. Remove the steak from the grill and let it rest for 5 minutes before slicing.
    
    
12. Assemble the sandwich by spreading aioli on the bottom half of the ciabatta. Top with sliced steak, caramelised onions, and fresh rocket. Close and serve immediately.
