As it bakes, the sliminess goes away, same as when it is fried. I usually turn mine with a flat spatula / hamburger-flipper.

I'm trying to picture slicing Okra lengthwise, which I assume is what you mean?
Thanks for that suggestion @thekittygirl, I will have to give it a try

I suppose it could be sliced lengthwise, but I usually slice mine cross-wise, in little circles, just like I would do if I were breading it & frying in a skillet. 🙂

From something in the original comment, I assumed you meant lengthwise. Little circles makes a lot more sense.
Thanks again @thekittygirl
