  • Step 1

    Remove steak from the fridge 30 minutes before cooking. Season both sides with salt and pepper as desired. Install the Accessory Frame in the bottom level of the unit, then place the Pro-Heat Tray on top

  • Step 2

    Turn dial to select MAX ROAST, set temperature to 315°C, and set time to 10 minutes. Press START/STOP to begin preheating (preheating will take approx.10-15 minutes)

  • Step 3

    When unit is preheated and ADD FOOD and PRS STRT is displayed, open door, and place steaks, onions and garlic on the tray. Close door, select START/STOP to begin cooking. Cook for 10 minutes, flipping the steak halfway through and tossing both the onions and garlic

  • Step 4

    For a medium-rare steak, cooking is complete when an instant-read thermometer reads 50°C. Open door and transfer steak to a cutting board to rest. If a more well-done output is desired, increase the time and continue to cook the steak. Be sure to remove the onions and garlic to avoid burning

  • Step 5

    Transfer onions and garlic to a cutting board and finely dice. Place in a medium bowl along with the butter, parsley and Worcestershire sauce and mix until evenly combined. Season as desired

  • Step 6

    Slice the steaks and top with prepared butter for serving
