Hello George. Welcome to cooking with an air fryer. You do not need chemical cooking sprays or complicated seasoning blends to achieve the rich flavor and crisp texture of a traditional oven roast. An air fryer is essentially a very efficient convection oven, meaning standard cooking oil, salt, and proper heat will yield excellent, classic results.
First, traditional roast potatoes are remarkably easy. Cut floury potatoes such as Maris Piper, King Edward, or Russet into even chunks. For the best result, parboil them in salted water for roughly five to seven minutes, drain thoroughly, and gently shake them in the colander to rough up the edges. Toss them in a mixing bowl with standard vegetable oil, olive oil, or melted dripping along with sea salt. Cook at 200 degrees Celsius (400 degrees Fahrenheit) for twenty to twenty-five minutes, shaking the basket halfway through until they are crisp and golden.
Second, root vegetables like carrots and parsnips roast beautifully together. Peel and slice them into uniform sticks so they cook evenly. Toss them in a bowl with a tablespoon of olive oil, salt, black pepper, and optionally a small drizzle of honey or a pinch of thyme. Roast at 180 degrees Celsius (360 degrees Fahrenheit) for fifteen to eighteen minutes until tender in the middle with caramelized edges.
Third, broccoli or cauliflower florets provide a fantastic everyday side. Cut them into medium florets, make sure they are completely dry after washing, and toss with olive oil, salt, and a touch of black pepper. Air fry at 190 degrees Celsius (375 degrees Fahrenheit) for eight to ten minutes. The hot circulating air browns the tips while keeping the stalks tender-crisp.
The most important guideline for traditional results is to always coat your vegetables in a bowl with real oil before they enter the basket, and ensure you do not overcrowd the basket so the hot air can circulate freely. I hope you enjoy your new appliance.
