Prepare the marinade: mix salt, pepper, mayo and onion rings, throw in the chicken thighs. Leave for 5-10 min (depending on how much time you have, if you are short on time, just start baking your chicken immediately).
Preheat your oven at 350 F. Put the chicken to bake for 30 minutes.
15 minutes before taking the chicken out: wash and peel the apples, slice the strawberry. When turning the chicken thighs around, put under them: apples and on top the strawberry. Bake for another 15 minutes. Check with the toothpick for the readiness, there should be juice in your chicken but it shouldn’t be too juicy (because this will mean that the chicken is raw, mind the color of the juice out of your chicken, it should be transparent)
If you want to serve your chicken with potato, just wash the potato, don’t peel it, cut in rings and put baking together with the chicken. The potato will be golden brown and crispy.
