Instructions
- 1
Place the Joule Turbo Sous Vide inside a pot or large vessel (max 8 litres) and place on a trivet. Fill with cool tap water until approximately halfway between the minimum and maximum fill lines and keep the pot uncovered.
Tip: A trivet will protect your benchtop from direct contact with the hot pot or vessel. - 2
Place the steak in a microwave-safe, zip-lock freezer bag. Sprinkle with salt and add the oil.
- 3
In Breville+, press Set Time & Temp at the bottom of the screen and follow the prompts to customise the cooking of your steak. Once set, lower the bag into the water against the side of the pot, while using a spatula to push it three-quarters of the way down. This will remove the air and ensures it does not float. Seal the bag and Start Turbo, continue to the next step.
- 4
To preheat the oven, insert the wire rack into position 5. Set the oven to Roast, Convection, 165°C, for 15 minutes and press Start. Meanwhile, continue to the next step.
- 5
Cut the leek in half lengthwise, then into thirds crosswise. Place cut-side up in the roasting pan, brush with oil and sprinkle with salt. Turn the leek over and brush the other side with oil.
- 6
Tear the bread into approximately 5mm pieces. Place in a large bowl with the almonds, hazelnuts, olive oil, garlic, ¼ teaspoon salt and pepper and mix to combine. Transfer to the roasting pan with the leeks. Set aside the bowl.
- 7
Once the oven has preheated, place the roasting pan in the oven and cook for 15 minutes, stirring the bread mixture halfway through cooking.
Tip: Stale bread will cook quicker than fresh bread, so keep an eye on it and remove the bread pieces if they’re over browning. - 8
In the reserved bowl, add the capsicums, tomatoes, paprika, vinegar and remaining salt and stir to combine.
- 9
Transfer the bread mixture to a small bowl and set aside. Add the capsicum mixture to the pan with the leek and return to the oven. Set aside the bowl. Cook for 10 minutes, stirring the capsicums halfway through cooking.
- 10
Once cooked, remove and discard the outer layer of the leek. Return the capsicum mixture to the bowl. Add the bread mixture and stir to combine.
- 11
When the timer signals that the steak is done, heat a cast iron skillet or heavy-based frying pan over high heat. Carefully remove the bag from the water. Place the steak on a paper towel lined cooling rack set over a tray and pat dry.
Tip: Alternatively, preheat the Sear and Press Grill to Sear (230°C). - 12
Only when the pan starts to smoke (this will prevent overcooking and sticking), add the oil to the pan and sear the steak for 30 seconds on each side. Transfer the steak to a cooling rack set over a tray and rest for 1 minute.
Tip: For extra flavour and colour, you can add a knob of butter and baste the steak while searing. If using the Sear and Press Grill, close the lid and sear for 30 seconds. - 13
Slice the steak, transfer to a serving plate and serve with the chunky romesco and roasted leek.
