Zucchini and Parmesan Casserole Squares

Take some of those plentiful summer zucchini and turn them into a delicious cheesy side dish!

     This cheesy zucchini casserole is a fun new way to serve the vegetable.  It works as both a starchy and vegetable side dish.  So you can get away with only making one if you would like! Of course the cheese helps win over anyone who may have been on the fence otherwise!

     Zucchini season is here again!  I told you about the phases of zucchini season when I shared the recipe for brown sugar zapple crisp with you.  This year there's even more!

   We are getting zucchini in our CSA boxes in addition to the zucchini from my brother and he is getting and sharing tons!  I am not complaining though, we love zucchini.  It just gives us extra incentive to get a little creative with how we fix it.

    I saw a recipe for a cheesy zucchini bake and it looked interesting.  I did make a few changes though.  First, I used biscuits for the base instead of crescents.

   I like the buttery flakiness they added and without the sweet that the crescents sometimes bring to a dish.  My husband tends to not like the sweet, so I made that change mostly for him.

   I also love zucchini and Parmesan together. So I wanted to bring that flavor forward. Plus it is perfect paired with the basil.

    I fully expected my husband to still not be a huge fan, despite the change away from crescents.  He didn't expect to like it either.  After a few bites, he said I expected this to only be edible but it's actually really good.

   Sometimes you have to take compliments however you can get them!
