Zucchini Squares
I have been scavenging in my grandma’s recipe collection again, and unearthed this beauty a couple of weeks ago. As I mentioned when I posted the Zucchini Pineapple Bread, my grandfather had a large garden that supplied a bounty of fresh vegetables for months upon months during the warm weather. My grandma had all sorts of creative ways for using up all of that great produce, and she has an especially large collection of zucchini recipes. Most likely because zucchini can grow like mad and she had zucchini coming out of her ears! Since I’m not big on vegetables, I am loving experimenting with zucchini in all of these yummy baked goods; eaten like this, I could eat it all day!
Now, I’m going to come right out and address the elephant in the room. Yes, there is Bisquick in this recipe. No, I usually don’t bake with pre-made, processed mixes or ingredients like that. BUT. Yes, there’s a but. When it comes to old-fashioned recipes, I am always willing to bend the rules. Because taste is such a strong connector to memories, when you start playing around with those old recipes, suddenly they don’t evoke the same feel or memory because they don’t taste quite the same. They might taste equally as good, or even better, but just not the same. So when it comes to my grandma’s old recipes, I bend my kitchen rules. Plus, the fact that I don’t use processed foods or ingredients 90% of the time makes me feel okay about doing it occasionally for something special.

(Plus, where would all those wonderful cookies and cream desserts come from without Oreos? ;-))
So, this is pretty much addicting. Which took me completely by surprise. I haven’t had these since I was a kid, but I couldn’t stop eating once it came out of the oven. It has the consistency of a souffle, filled with zucchini, a little onion, Romano cheese and some herbs and spices. Lots of delicious flavor! You could serve this as a side dish (larger squares) or cut them up into smaller cubes (below) and serve it on an appetizer tray. I personally like the idea of the small squares so that I can keep eating more and not feel bad about it!

Zucchini Squares
Ingredients
- 5 eggs, lightly beaten

Instructions
- 1. Preheat oven to 350 degrees F. Grease a 9x13 pan and set aside.
- 2. In a large bowl whisk together the eggs, oil, Romano cheese, parsley, salts, oregano and garlic powder. Whisk in the onion, and then the Bisquick.

These zucchini squares look delicious and I like that you incorporated some diversely flavoured herbs – the romano cheese sounds pretty wonderful too. Lovely!
These look great! I love learning new recipes for how to incorporate zucchini into baking, and not just having it as a side dish with dinner! I recently found and made a great zucchini bread cookie sandwich recipe – it was so good! This is the link: http://sherrilynnpuz.blogspot.com/2011/06/zucchini-nut-bread-cookie-sandwiches.html
I’m on a squash kick right now, as well!
So definitely bookmarking this one!!!
I love bisquick! Haha is that weird? This bread looks so good! I want to make soon!
Reading your blog is like going to the grocery store – I should never visit when I’m hungry. I could eat the whole pan.
They still make Bisquick? :-) What I love about your grandmother’s recipe is the use of thin slices of zucchini. I have not eeen this before and it’s very beautiful. And the way you describe the texture makes it a must-try for me. …Susan
I love the look of a more savory bread for the bounty of zucchini; my very old recipe uses a lot of oil and a lot of sugar. It’s a lot of good but also a lot of guilt!
And no apologies necessary. Bisquick hardly even qualifies as processed in my book anymore than self rising flour does! I have a cake I make during the holidays. One of those that use a box mix and pudding. It is so good (I’m sure the REAL butter and REAL rum do help!) that I gave up thinking I needed to revise it. We know what you’re made of…and I’m glad you shared this with us!
I LOVE this recipe. Yes, it is a staple in our house during the “plentiful” season!
This sounds really yummy and I am thinking this might work as the centerpiece of a meatless meal as well! And don’t feel guilt-ridden about the Bisquick!
Oh what a great reminder, my mom makes something like this that I love! And just yesterday my neighbor said he had lots of zuchinin I could come pick, perfect!
Perfect summer meal…My grandma used to make this every year. Serve with a crisp salad on a hot night and dinner is done.. Thanks for sharing this recipe, it brought back memories ;-)
This looks amazing! I also have zucchini coming out of my ears and need lots of recipes for it!! Could this be made ahead and frozen??
Hi Lauren, I actually am not sure about freezing; it’s not something we’ve ever done since it goes so fast! I’m not sure how thawing would affect the texture (I’m thinking it might be a little mushy). I’m sure it would still be edible, though. If you give it a try I’d love to hear how it goes!
Incorporated into baked goods is the best way to get your daily dose of vegetables!
This looks amazing!
I could spend an entire day on your YUMMY site!
Pinning this big time!
Must make!
Thanks for all that you share!
Love it!

These are amazing! Such a pretty bar. I love zucchini muffins, and I have a recipe that uses bisquick for them. They are so good, I just haven’t been brave enough to mess with them. I am going to have to try these next time I have zucchini!
My mom makes the exact same thing only no starch component and it’s one of my favorites. I’ll have to try it with the bisquick.
We make a similar spinach square recipe, but this looks even better. I can’t wait for our garden to start producing zucchini…. the flowers are just about ready to open!
I love vintage recipes – how wonderful that yours come from family members. I have to say – I am the ONLY person in my family who cooks….although, my niece is learning! So – I have no recipes, but a bunch of vintage cookbooks!
This looks AMAZING – I love zucchini by itself and even more in recipes!
Old family recipes are the best! This looks fabulous. I’m bookmarking this to make when there’s an abundance of zucchini this summer!
Mmmmm, these look GOOD! We have zuchinni and summer squash that are just now coming on, so I’m going to store this one away to use in a few weeks. Since I don’t have the memories of what these taste like without Bisquick, I’ll try to sub out for it. I’ll let you know how they turn out!
i’ve never heard of zucchini squares before, but they look absolutely delicious. MUST.TRY.NOW :)
My mom used to make these when I was a kid! Whats even funnier is I still have a box of bisquick from when I made them for an appetizer party I had at my house 3 years ago!!! I obvioulsy don’t use bisquick either!
Looks so rich and tasty! If that’s the family recipe, it is what it is.
Time to go find that bisquick mix recipe I’ve got somewhere. If it were not for the allergy issues, I’d use the real thing to make these. I’ve always got an extra zucchini lying around the house.
This looks delicious, bisquick included or not:-)
Yum! Love the pops of green!
Woo Hoo! Another zucchini recipe!!! Keep them coming, Michelle!!
And yes, sometimes we HAVE to use Bisquick, such as when attempting to replicate the pancakes mom made when I was little covered in Vermont Maid maple syrup. Some things are not to be messed with – I’m all for the same memories and TASTE!
I don’t mind you baking with Bisquick! These look lovely!
I love old family recipes! This looks delish! I need to find someone with some zucchini they want to give away!!
