First of all, it depends on the size of the whole chicken. Generally, it is no problem to put a chicken of about 1-2 pounds in an oven of about 30 liters. As the size of the chicken increases, the capacity of the oven must be increased, otherwise it will be too large. Small ovens tend to burn the chicken. Let me share a roast chicken I made. If the oven has a fork-turn function, you can use it. If not, place it directly on the baking sheet. You can also turn it over halfway. Ingredients required for aromatic roast chicken: 1 three-yellow chicken, about 800 grams, 50 grams of barbecue powder, 30 grams of water, 3 slices of ginger Preparation: Wash the three-yellow chicken, and use toothpicks to poke small holes in the strong breast meat and thighs for convenience Pickled and flavorful. Mix the barbecue powder and water and apply it evenly on the inside and outside of the chicken. Apply it 3 times. Put the chicken in a plastic bag, pour in the remaining juice, seal and refrigerate overnight, take it out the next day and wrap it in tin foil. Remove the chicken tips and chicken leg bones, and place the whole chicken on a baking sheet lined with oil paper. The oven machine selects the "hot air bake" function mode, sets 190 degrees preheating, and starts the program. After preheating, place the baking pan into the middle and lower layers of the machine, activate the "hot air baking" function mode, set 190 degrees for 40 minutes, and start the program. The roasting time for the chicken is about 40-60 minutes, depending on the weight and coloring of the chicken. Flip it over halfway to make the color look better. Just put on oven mitts and remove the food.
