Q.Is large zucchini which is yellow inside safe to eat
I picked zucchini which are one foot and larger. They are yellow and tough on the inside. Are they still good to bake with?

These look fine. They've over-grown and may be tougher than others, but if you remove the seeds and just use the flesh, they should be quite edible. Unless a squash is mushy or stringy on the inside or has very dull or marred skin, it should be okay to use for cooking. https://www.gardeningknowhow.com/edible/vegetables/zucchini/zucchini-squash-harvesting.htm
