Zucchini Casserole Recipe -My Garden Overfloweth

Zucchini have to be the most prolific vegetable on earth.ย  Once they start ripening in the garden the game is on! How do I get the family to eat all of them? You can’t give them away as everyone who has a garden has an overflow too. Note to purveyors of seeds – You only need to put about 6 seeds in a packet!

Zucchini squash growing in the garden just about to be picked to use in the preparing of Zucchini Italiano Casserole Recipe, my favorite zuchini redipe
Our garden is bursting with medium sized zucchini. and this casserole is the perfect way to use some up.

So what do I do to use up all my zucchini – everything!!!! I pickle them in a variety of ways – dill, zesty, bread & butter.ย  I make them into relish.ย  I serve them stuffed, hidden in casseroles, sauteed, bread, muffins…..I think you’re getting the picture.ย  Over the years, I have cooked a fair amount of zucchini and have developed a number of recipes to make them different and exciting.ย  OK…who am I kidding…zucchini…exciting….. in the same sentence, I got a little carried away.ย  Must have had too much zucchini, but honestly, there is a way to use most of the zucchini from your garden and not bore your family’s taste buds to death. During the next month I will be posting a number of zucchini recipes so stop in frequently to collect them all. The first that I am sharing is Slow Cooker Zucchini Italiano Casserole.ย  I love to cook this casserole in the summer because my crockpot will not heat up my kitchen like my oven would.

For this recipe, you will want to slice medium sized zucchini about 1/4 inch thick.

you can consider this a side dish or a main course.ย  It is very rich and very filling.ย It’s a casserole that I let cook in the slow cooker for a few hours and then just before I serve it, I put into a casserole dish, top it with cheese and buttery cracker crumbs, and melt the cheese under the broiler. It’s delicious, economical, and easy!ย  That combo works for me.

      Hi Richard,
      You could use any cracker that you wanted but I have to admit that Ritz Crackers are my go to cracker for any casserole crumb topping. I love the rich buttery flavor of Ritz Crackers (butter being the operative word here). This is a great time of the year for zucchini recipes. My garden is bursting at the seams with zukes. I have been making them into relish and pickles because the family is turning green when I even mention the word zucchini.

    How many will this dish serve? It’s just my husband and me so I could probably cut it in half if necessary…or make the whole thing and munch on it as leftovers! Sounds absolutely delicious!!

      If you read my recipe “disclaimer” on this website, I don’t ever claim to be a healthy cook! I’m sort of the Paula Deen of the North Woods! But any recipe can be made healthier by reducing salt, substituting low fat ingredients for the cheeses and butter that I use. And of course, all things in moderation….you don’t have to eat the whole thing in one sitting!

      Lyn, can you tell me when do you add the cubed cooked chicken? I love this idea, including the garlic toast and Caesar salad, because it turns into a complete meal. Thanks much, Trish

        I am anxious to hear Lyn’s reply, and whether the chicken was precooked or not. Sounds like a good addition and brings the dish from a side to an entree!

    This dish looks fantastic. I don’t grow my own zucchini but I probably should because my family loves it. I love the technique of cooking it in the slow cooker and then finishing it under the broiler. Great idea!

    I would love for you to come over and link up at Wine’d Down Wednesday if you get a chance. We are partying from now until Friday! Hope to see you there! http://www.dizzybusyandhungry.com/wined-wednesday-link-party/

    I hope my parent’s zucchinis grow well this summer. This sounds absolutely delicious. My Mom made a tomato dish tonight for supper that was incredible. She got the recipe from the Mennonite cookbook. I complimented it about three hundred times, so I hope she got the hint and will bring it over to our house one day soon for dinner : ).
