Take the soft butter and minced garlic. Also add the thyme and rosemary. Mix good. Slice the onions in half. Take one have and thinly slice. Take the other half of onion and cut into half again.

Add the vegetables to a baking pan. Pat the chicken dry, this will allow for a crispy chicken. Add some of the garlic herb butter under the skin of the chicken breast and massage it. Coat the chicken with the garlic butter. It works best to press the onion onto the garlic butter, it doesn't stick to onion.

Push the half onion that is halved again into the cavity of the chicken. Put the chicken into the midst of the vegetables in the baking pan. Set into oven for 50- 60 minutes.
