Green and Gold Squash Casserole

Sharing is caring!

Green and Gold Squash Casserole is a scrumptious side dish that is loaded with garden fresh zucchini squash, corn, onion, and a light cheesy egg batter and topped off with more cheese! Simply put…it’s Superb!

I get asked where my inspiration comes from when creating new recipes. Depends on the day and my mood! (Bad mood days are not worthy of print! Lol)

Green and Gold Casserole with Zucchini

One of my favorite sources for inspiration are old cookbooks found at Thrift Stores. I could spend hours scouring through them for forgotten gems! I generally tweak the original recipes here and there. To suit my tastes. In my mind I just know what is going to work and what isn’t.

I was thrilled when I stumbled upon this gem in a Thrift Store cookbook last week! I knew it was going to be good. I just didn’t realize HOW good! The ingredients are so simple…the results AMAZING! (You’re gonna find yourself wishing you had planted more zucchini…ya may also find yourself in the mental hospital! Lol

How To make Summer Green and Gold Squash Casserole

I love the simplicity of this recipe. You’ll need 2 lbs. of zucchini sliced, or chunked, into 1/4 – 1/2 inch pieces. Boil in salted water for 10 minutes or until tender.

Zucchini Squash boiling in water

Drain cooked zucchini well. I used a colander and just let it sit in the sink about 30 minutes. (I swear zucchini retains water better than a pregnant woman’s ankles in the middle of July!) 

Once squash is well drained…place squash in a large bowl and mash with a potato masher.

NOTE: This is gentle mashing…this is not a “I’m gonna hurt that child if he forgets his homework one more time” mashing! (These are “professional” cooking descriptions…only found here! You’re welcome!) 

Mashing Squash

Add One 12 oz. can corn, drained.

NOTE: I used fresh cooked corn, cut off the cob. I had three ears left over from Sunday dinner. So you can use either fresh corn or canned corn.

Adding Corn to casserole

In a small mixing bowl, or measuring cup, beat together two eggs, add in 1/2 tsp. salt and 1/4 tsp. coarse ground pepper.

Eggs and seasonings in measuring cup.

Add egg mixture to mashed squash and corn. Add in 1/2 cup chopped onion.

Addition of egg to squash and corn

Add 1 1/2 cups of grated cheddar cheese. Confession time…the original recipe calls for 1 cup of cheese. When it comes to cheese… I’m a “Go B.I.G. or Go HOME!” kinda gal! So another little handful of cheese may have made its way into that bowl! (It was so yummy! So…GO BIG!) 

Addition of cheddar cheese to casserole mixture

Mix all ingredients together. Making sure everything is well incorporated.

This was the point my heart started to sing! The colors and textures of this dish were just sublime! Truly the makings of a fantastic dish!

Zucchini Squash and misc. ingredients mixed together

Pour into a greased 2 quart baking dish. Isn’t that pretty?

Squash and Corn mixture poured into prepared 2 qt baking dish

Top it all off with….can you guess? Come on… Go BIG or GO HOME! (This hint is just one reason I’m not allowed to play board games or cards! Which I’m okay with…) 

MORE CHEESE PLEASE! Sprinkle 1 cup of cheese on top of casserole.

Bake in a preheated 350° oven for 40 minutes or until set! 

TIP: How do we know if it is set? Again I offer another stellar “professional” cooking description for you! Does it jiggle like great grandma’s chest? If so…push that baby right back in the oven. If… when you gently shift the dish around…nothing budges like “The Rock”, Dwayne Johnson’s, chest…bring it on out!  Did y’all see the new Jumanji movie? Huh? (Squirrel)

I completely forgot what we were talking about…

SQUASH! Squash casserole…EPIC Squash Casserole. (I’m back!)

NOTE: Let that cheese brown a little! It makes the dish so appetizing!

I should warn you…this casserole will have your house smelling like Thanksgiving. The air will fill with the most incredible savory scents! It is truly amazing.

Green & Gold Casserole

I was so excited about this dish and how tasty it is… that I called friend over and begged her to be my “tester”.  She loved it so much she took all my extra garden squash and ran home and made it for dinner for her family!

Mr. Nest declared this his favorite new side dish and proceeded to have THIRDS!!! (Whoa!) 

The flavor combination of ingredients in this simple dish is spectacular! As I mentioned earlier…this is one for the “family cookbook”! It will be making regular appearances at our dinner table!

I served it with Grilled Marinated Pork Chops, Fresh Garden Tomatoes & Cottage Cheese, Melon, and Garden Potatoes. It was an awesome end of summer dinner!

The Gold and Green Squash was the Main Attraction!

Gold and Green Casserole

Thanks so much for stopping by my Nest! I hope you’ll use some of that extra garden squash and make this recipe as soon as you can. You won’t be disappointed!

I love this recipe! I do sauté the onions and butter. I also add minced garlic then I put the squash in the same pan until it’s tender. I top it with crackers and more cheese. I have also added cream, either half-and-half or whipping on occasion.

My MIL made something like this one time, and my SIL remade it, but nobody could tell me the recipe! This looks like it only it had a cracker crust, like someone suggested! OH MY! Cannot wait to make this! I grew yellow zucchini this summer, it will be perfect for it. Thanks Norine!

Hi Brenda! YES! I thought the same thing after I made it. I'm going to add it next time I make it. The additional flavor and "crunch" will be the perfect addition. Thanks for stopping by and for sharing your idea with me. I absolutely love great minds that think alike! Have a wonderful week! Happy Nesting! ~Norine
