It most definitely does require that (at least) ten minute wait before cutting for it all to firm up. I actually let it sit quite a bit longer than that and it was a little loose. My tomatoes were very ripe and juicy. Next time, I might layer the crumbs among the vegetables. It didn't come out of the pan in perfect little squares. Sure is tasty, though, and the zucchini was nicely al dente. I think this is going into the regular rotation.
