Do you put the okra in a basket? Do you cut them in any particular way?
Okra does take well to char and to crisping. I like to do chicken thighs (with salt and cayenne rubbed under the skin and over the bottom) at 450-480 in my toaster oven and I usually scatter diced potatoes around to absorb the fat. But I did okra once (sliced lengthwise) and it emerged wonderfully crisp with charred bits here and there.
