Let's prepare all the necessary ingredients on the work surface.
In a small bowl, combine sunflower or olive oil and soy sauce, then add honey, dried garlic, seasoning, ground pepper, and half a teaspoon of salt. Mix thoroughly.
We wash and dry the gutted chicken carcass (preferably a large one) on all sides (including the inside) with the prepared marinade and leave it to soak at room temperature for at least an hour.
Cut the unpeeled apples into wedges, removing the seeds. Set some aside for the base. The rest will be used to stuff the carcass.
Mix a tablespoon of melted butter with half a teaspoon of salt. Rub the butter under the skin of the chicken breast to infuse the chicken with the buttery flavor and keep it juicy.
Stuff the chicken with some of the apples and add a sprig of rosemary.
Line a baking sheet with parchment paper or foil, arrange the apple slices on it, and then place the chicken on top. Secure the legs with string or a skewer, and attach the wings to the chicken with toothpicks to prevent them from rising and burning during cooking. Arrange the remaining apples and chopped rosemary around the chicken.
Wash the garlic, remove the top two layers of skin, cut it in half so that the heads do not fall apart into cloves, and place them on both sides of the carcass, cut side up.
Bake the chicken in a preheated oven at 180°C (350°F) for 1.5–2 hours using the top-bottom setting. Cooking time can vary significantly depending on the oven type and the size of the chicken, so it's a good idea to check the chicken after an hour.
When the chicken is browned, you can turn it over and put it back in the oven for another 20 minutes, turning on the convection mode.
