How to roast chicken fillet?

The roasting method of chicken fillet is very simple. Usually, we'd better buy ready-made fried chicken fillet. If you cook your own chicken fillet, the label says roast, which is a bit unrealistic. You can spread a layer of tin foil on the top and bottom of the tray in the oven, put this chicken fillet on it, and then adjust the temperature to about 120 degrees for about 20 minutes.
