For zucchini, you need it to "weep" some of the excess water it is holding. I take care of this by
1) sprinkling some salt over the cut up slices of zucchini and letting it sit in a colander for 30 minutes and
2) after, wiping off the salt and taking a paper towel and sopping up any leftover excess moisture.
***if you are wanting to make zucchini lasagna, I would go a step further and individually grill the pieces (in a George Forman) before doing your layering for the lasagna.
It worked for me! Hope this helps.
