- 1
To preheat the oven, insert the wire rack into position 5. Set the oven to Bake, Convection, 355°F for 20 minutes and press Start. Meanwhile, continue to the next step.

Place the potatoes in a medium saucepan and cover with cold water. Bring to a boil over high heat, then reduce the heat and simmer for 20 minutes, or until tender. Meanwhile, continue to the next step.

Place the garlic and olive oil in an ovenproof ramekin. Cook in a preheated oven, at 355°F, on a baking sheet for 20 minutes or until garlic is softened and golden. Meanwhile, continue to the next step.

Place the Joule™ Turbo Sous Vide inside a pot or large vessel (max 8 quarts) 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 countertop from direct contact with the hot pot or vessel. - 5
Place the steaks flat, side by side in a large microwave-safe, zipper-lock freezer bag. Add the salt, garlic powder, onion powder, thyme and mushroom powder and shake to coat.

In Breville+, press Set Time & Temp at the bottom of the screen and follow the prompts to customize 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, then continue to the next step.

Once tender, drain the potatoes and return to the pan. Add the roasted garlic and oil, salt and butter, then mash using an immersion blender with the ricer attachment. Cover to keep warm.
Tip: Alternatively you could mash with a fork. - 8
When the timer signals that the steaks are done, heat a large, cast iron skillet or heavy-based frying pan over high heat. Carefully remove the bag from the water. Place the steaks on a paper towel lined cooling rack set over a tray and pat dry.
- 9
Only when the pan starts to smoke (this will prevent overcooking and sticking), add the oil to the pan and sear the steaks for 30 seconds on each side. Transfer the steaks to a cooling rack set over a tray and rest for 1 minute.
Tip: For extra flavor and color, you can add a knob of butter and baste the steak while searing. - 10
Transfer the steaks to a serving plate and serve with the mashed potato sprinkled with combined extra mushroom powder and salt.
