Tips:

Choose tender zucchini: Smaller zucchini are more tender and have fewer seeds. But you can use any size zucchini, just be sure to slice them thinly.
Use a sharp knife or mandoline: This will help you get thin, even slices of zucchini.
Don't overcrowd the pan: When browning the zucchini, don't overcrowd the pan or else they will steam instead of brown.
Use a good quality cheese: The cheese is one of the key ingredients in this dish, so use a good quality cheese that you enjoy. Grated Parmesan, Gruyère, or a combination of the two are all good choices.
Don't overcook the casserole: The zucchini should be tender but still have a little bite to it. Overcooking will make the zucchini mushy.
