Sheet Pan Chicken and Green Beans

So I'll need to review the recipe again, but after 30 minutes in the oven (the chicken breasts I used were larger than what was in the video) the green beans were completely uncooked. They were hot but just as crunchy as they would be if you grabbed them off the shelf at the grocery store. Tanked the whole dinner for me which is a shame since the chicken was really good. Next time I'll probably steam the green beans for a while before they go in the oven.
