Rub your piece of meat all over with a bit of olive oil, season with pepper and salt, insert the core thermometer nicely in the middle of the piece of meat, and place it directly in the back of the airfryer basket. First, set the core temperature to 50°C if you want the cooking method to be rare, then close your device. Set it to 180°C and high ventilation (the 2 fans), this will nicely color the meat. Let it color now and cook until the red circle on the screen is half filled.
Meanwhile, peel the carrots and asparagus and cut them along with the baby potatoes and cauliflower into equal pieces. Shake the vegetables separately with a teaspoon of oil and season with pepper and salt. When the red circle is half filled, the vegetables can go in, close again, and cook until the core temperature is reached and it shuts off. And that’s it, really, crazy 😉 While baking, make the sauce.
Let the meat rest for 5 minutes, serve the vegetables and watercress on warm plates. Slice the roast beef into thin slices of half a centimeter, distribute on the plates, and serve with the sauce.
