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

Yield: 16 large or 24 to 30 small

Prep Time: 15 minutes

Cook Time: 25 to 30 minutes

Total Time: 45 minutes


5 eggs, lightly beaten

½ teaspoon seasoned salt
½ teaspoon dried oregano
¼ teaspoon garlic powder
½ cup finely chopped yellow onion
2 cups Bisquick
3 cups thinly sliced zucchini


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.

    I love old family recipes! This looks delish! I need to find someone with some zucchini they want to give away!!


  2. Katrina on June 28, 2011 at 12:49 am

    I don’t mind you baking with Bisquick! These look lovely!


  3. Lynne @ 365 Days of Baking on June 28, 2011 at 1:39 am

    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!


  4. Blog is the New Black on June 28, 2011 at 5:27 am

    Yum! Love the pops of green!


  5. Lauren at Keep It Sweet on June 28, 2011 at 6:11 am

    This looks delicious, bisquick included or not:-)


  6. Apron Appeal on June 28, 2011 at 6:18 am

    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.


  7. Adriana on June 28, 2011 at 6:36 am

    Looks so rich and tasty! If that’s the family recipe, it is what it is.


  8. Marcy S on June 28, 2011 at 7:30 am

    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!


  9. Heather (Heather's Dish) on June 28, 2011 at 7:47 am

    i’ve never heard of zucchini squares before, but they look absolutely delicious. MUST.TRY.NOW :)


  10. Ferreh on June 28, 2011 at 8:11 am

    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!


  11. Colleen @ What's Baking in the Barbershop?! on June 28, 2011 at 8:14 am

    Old family recipes are the best! This looks fabulous. I’m bookmarking this to make when there’s an abundance of zucchini this summer!


  12. Claire @ Live and Love to Eat on June 28, 2011 at 8:56 am

    This looks AMAZING – I love zucchini by itself and even more in recipes!


  13. Ann on June 28, 2011 at 8:57 am

    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!


  14. SnoWhite @ Finding Joy in My Kitchen on June 28, 2011 at 9:21 am

    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!


  15. Rodzilla on June 28, 2011 at 9:32 am

    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.


  16. Erin @ Dinners, Dishes and Desserts on June 28, 2011 at 9:36 am

    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!


  17. teresa on June 28, 2011 at 10:38 am

    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!


  18. Erin on June 28, 2011 at 10:43 am

    Incorporated into baked goods is the best way to get your daily dose of vegetables!


  19. Lauren on June 28, 2011 at 11:10 am

    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??


    • Michelle on June 28th, 2011 at 11:16 am

      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!


  20. gina on June 28, 2011 at 12:08 pm

    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 😉


  21. Glory/ Glorious Treats on June 28, 2011 at 12:29 pm

    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!


  22. Deborah Dowd on June 28, 2011 at 12:46 pm

    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!


  23. Rosemarie Royce on June 28, 2011 at 12:54 pm

    I LOVE this recipe. Yes, it is a staple in our house during the “plentiful” season!


  24. Barbara | Creative Culinary on June 28, 2011 at 1:29 pm

    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!


  25. LunaCafe on June 28, 2011 at 3:15 pm

    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


  26. Lisa @ The Cooking Bride on June 28, 2011 at 4:40 pm

    Reading your blog is like going to the grocery store – I should never visit when I’m hungry. I could eat the whole pan.


  27. Lindsey@Lindselicious on June 28, 2011 at 8:43 pm

    I love bisquick! Haha is that weird? This bread looks so good! I want to make soon!


  28. madge @ vegetariancasserolequeen on June 28, 2011 at 10:08 pm

    I’m on a squash kick right now, as well!

    So definitely bookmarking this one!!!


  29. sherri lynn on June 29, 2011 at 8:13 am

    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


  30. Kelly on June 29, 2011 at 12:45 pm

    These zucchini squares look delicious and I like that you incorporated some diversely flavoured herbs – the romano cheese sounds pretty wonderful too. Lovely!


  31. Tiffany on June 29, 2011 at 7:51 pm

    What an awesome family recipe!


  32. Sandra's Easy Cooking on June 30, 2011 at 1:31 am

    Pictures are mouthwatering and recipe just wonderful!!! Congrats on making top 9!!!


  33. Tiffany on June 30, 2011 at 7:15 am

    Hi again! Congrats on your Top 9!


  34. Helen on June 30, 2011 at 9:41 am

    I have an over abundance of yellow squash so I tried it in this recipe last night. It was delicious! I will make again for sure!


  35. Jim on June 30, 2011 at 12:59 pm

    My mom would make these every year for my birthday… as a kid I craved them.


  36. Jen @ My Kitchen Addiction on June 30, 2011 at 2:09 pm

    These look great! I was just thinking I needed to find some new zucchini recipes this year since we’ve already started getting quite a few from our CSA each week!


  37. Emily @ eat.drink.run. on June 30, 2011 at 4:09 pm

    I love making baked goods with zucchini! Its so versatile! I’ll have to look back to your zucchini pineapple bread as well – that also sounds delicious! Thanks for posting these delicious recipes!


  38. Ann on June 30, 2011 at 11:27 pm

    Congratulations on making FoodBuzz Top 9!


  39. Nicola on July 1, 2011 at 3:52 am

    These look yummy and would love to make them – one slight problem, I live in France so can’t buy Bisquick!!! (I hadn’t even heard of it before today) I googled it to find out what ingredients are in it, but what proportions would you use?


    • Michelle on July 1st, 2011 at 4:05 pm

      Hi Nicola, I really am not sure; I haven’t played around with a homemade Bisquick mix, but I think if you google you might be able to find some substitution recipes. Good luck!


  40. Dana on July 2, 2011 at 10:33 pm

    Whole Foods and Arrowhead Mills both sell a healthier version of Bisquick that should work just fine in this recipe!


    • Michelle on July 5th, 2011 at 1:06 pm

      Great to know, thanks for the tip Dana!


    • Dutch Fielder on July 10th, 2011 at 11:36 pm

      Michelle (and Nicola)
      This may be a bit late, but I have a recipe for “Master Mix developed at Purdue University. For cookies, muffins, chocolate and yellow cake, pancakes, waffles, coffee cakes, gingerbreads and biscuits. This quantity will yield 29 cups of mix.” Which is titled “A QUICK BREADS MIX- HOMEMADE BISQUICK” and a dozen or so recipes for using it that I will gladly E-mail if it will help.
      Great site,


  41. Melissa on July 4, 2011 at 11:26 am

    My mom has made these for years and they have always been a party favorite. She shreads the zucchini and puts quartered pieces of peperonni in hers.


  42. Heather on July 4, 2011 at 9:06 pm

    I made these as a snack for our 4th of July BBQ and had a bunch of snobby foodies present – they were a GIANT hit – thanks so much for sharing!!


  43. julieA on July 4, 2011 at 10:31 pm

    My garden is bursting with yellow squash, but the zucchini is taking it’s sweet, old time this year. Made 2 recipes of this, using the yellow squash, for us and a neighbor. Comments from both camps were similar: YUM and Delish!! Thanks for sharing the recipe.


  44. Ellin on July 5, 2011 at 1:01 am

    I am so glad I stumbled upon this recipe. A friend of mine used to make something like this with broccoli, and I have been looking for the recipe for years. My son who was little at the time used to love them. He was with me tonight when I found the recipe and said to me oooh mom that looks like the bread I used to love when we used to go to your friends house…can you make them for me tomorrow?? Hopefully he stills love them at 17….will make them as soon as possible!!!


  45. Mackenzie@The Caramel Cookie on July 6, 2011 at 8:06 pm

    I don’t use Bisquick often but it sure comes in handy when I want some biscuts and can stir up some in about 30 seconds :).


  46. Kristina Vanni on July 13, 2011 at 12:45 pm

    This is such an interesting recipe! Sort of biscuit meets quiche and filled with veggies…love it! I am always on the lookout for new ways to use zucchini during the summer. Can’t wait to try this one!


  47. Jennifer @ KitchenJoy on August 30, 2011 at 12:33 pm

    Could I substitute a different kind of cheese? I don’t have Romano. Also, somebody gave me a bag of “Granny Bunt’s Bakery Mix”- think that will work in place of Bisquick?


    • Michelle on August 30th, 2011 at 12:49 pm

      Hi Jennifer, You could substitute grated Parmesan cheese for the Romano. I’ve never heard of Granny Bunt’s Bakery Mix, but if it is similar to Bisquick – used for pancakes, waffles and biscuits, then I think you would be able to use it.


  48. kaeleen on January 20, 2013 at 8:51 pm

    I had a recipe for Zucchini bread I got from the back of a Bisquick box in the 80’s. This one is just about the same except it called for whole cloves of garlic instead of garlic powder and no seasoned salt and grated zucchini. Put all the ingredients, minus the bisquick, zucchini and cheese, into a blender and make like a liquid then mix the liquid with the bisquick, zucchini and cheese then pour into a pan to bake. It is very good! I’m so glad you posted this recipe, as I have not been able to find mine. Thank You!


  49. Mary on June 17, 2013 at 6:01 am

    My mom used to make this all the time as a kid but would sauté the zucchini with minced garlic and sliced onions. She would add the cooled mixture in at the end. She also added some cheddar cheese in addition to the Romano. Thanks for sharing the recipe as it was one recipe she didn’t make in a while and couldn’t remember the measurements. Thank you for sharing.


  50. Sharrell on July 12, 2013 at 8:15 pm

    I’m making this for dinner tonight. I love zucchini, so I’m always looking for other ways to use it. Love how good it smelled before I put it in the oven. Can’t wait to taste it. Thanks for the recipe.
