Open Steak Sandwich with Roasted Garlic Aioli

Instructions

• 1Insert the wire rack into position 6. Set the oven to Air Fry, Super Convection, 375°F, for 18 minutes and press Start to preheat. Meanwhile, continue to the next step.
• 2Place a piece of foil in the roasting pan, add the garlic and oil and fold into a parcel.
• 3Once preheated, place the pan in the oven and air fry for 18 minutes. Meanwhile, continue to the next step.
• 4To make the caramelized onion, melt the butter in a medium saucepan over medium heat. Add the onion and salt and cook, stirring for 5 minutes, or until the onion is soft. Add the sugar and thyme and continue to cook, stirring occasionally, for 3 minutes, or until the onion is very soft and starting to caramelize. Add the vinegar and deglaze the pan, stir until the vinegar has evaporated. Remove the pan from the heat and set aside.
• 5Carefully unwrap the foil. The garlic should be soft when pressed with a fork. If not, rewrap and air fry a little longer.
• 6Move the wire rack to position 2. Set the oven to Air Fry, Super Convection, 300°F, for 6 minutes and press Start to preheat. Meanwhile, continue to the next step.
• 7Place the broiling rack in the roasting pan and place the steak on top. Brush one side with the oil and season with salt and pepper. Repeat on the other side.
• 8Once preheated, place the pan in the oven and air fry for 6 minutes. When the oven signals at the end of cooking, adjust the oven to Broil, High for 6 minutes and press Start. Meanwhile, continue to the next step.
• 9To make the garlic aioli, using the back of a spoon, press the garlic through a sieve into a bowl. Add the mayonnaise and whisk to combine.
• 10The steak is ready when a meat thermometer inserted into the thickest part reads 133°F, for medium-rare. If you like your steak more well done, broil it a little longer.
  Tip: The shape of the steak, including the thickness, can alter the cooking time. For best results, test for doneness a couple of minutes before the end of the cook. It may need a little more or a little less extra cooking time, best to keep an eye on it.
• 11Remove the steak from the oven and let it stand for 5 minutes to allow the juices to settle. Meanwhile, continue to the next step.
• 12Place the mustard, lemon zest, juice and oil in a bowl and whisk to combine. Add the arugula and tomatoes and toss. Season with salt and pepper.
• 13Remove the wire rack from the oven. Place the bread in the air fry basket, insert the basket into rack position 1. Set the oven to Broil, High, for 7 minutes and press start. Halfway through broiling, turn the bread over and toast the other side.
• 14The toast should be golden. If not, broil it a little longer.
• 15Cut the steak into thin slices.
• 16Spread the toast with the aioli. Top with the onion and steak and pile the salad on top. Using a vegetable peeler, shave the parmesan over the salad.
