I just bought a new house and it came with a really beat up double oven from the 70's. I want to replace it. It is a 27" oven. I would prefer a wider 30" oven, but it would require a lot of cabinet work to make it fit. Can I get away with a 27" oven? Do regular baking sheets fit? what size chicken / turkey will fit inside? IWondering if I can get away with it. Any help is greatly appreciated.
