Squash Casserole is an essential dish for holidays and special meals. Topped with a buttery cracker topping, this squash casserole recipe is a delicious all-time favorite!
Squash Casserole is a one of those recipes that you’ll find for nearly every holiday, reunion, or special occasion when my family gets together.
To say that this recipe is a staple family-favorite would be a definite understatement, actually.
I’m sure if you’ve been to a southern family reunion anytime in your lifetime, you’ve most likely noticed the squash casserole dishes that always appear. And then disappear just as quickly.
It’s just one of those recipes that is a foolproof crowd pleaser. And this recipe is exceptionally delicious and frequently requested!
And this recipe is so versatile too! It’s perfect for feeding large groups of people. It’s just as perfect for feeding a family for supper too. Just simply divide this recipe for a smaller weeknight side dish to enjoy anytime!

I love to freeze precooked squash with onions just for this dish!
That’s wonderful to hear that you enjoy it, Frances! Thanks! xo
Made it and loved it. Making again today. Great low carb and low sugar recipe.
Glad you enjoyed it Joy! xo
Will be definitely trying this out today, adding a bit of fresh spearmint as well;) Thanx so much for the delicious recipe, greetings from sunny Greece!

It was fantastic! We sliced the squash using a mandolin to get thin slices and also tried a little Parmesan with it. Delicious, thanx for the delicious recipe!
I have made this a couple of times and it was a huge hit. I love this recipe.
It’s such a family favorite dish, so I’m so happy to hear that it was a hit for you too, Tammie! xo
For KETO: I subbed the ritz crackers with crushed pork rinds, Added 1/4 cup heavy whipping cream and 4TBSP cream cheese. Made this two nights in a row. Delicious!!
Thanks so much for that tip, Teresa. I’m so happy you liked it! xo
I made this tonight. Delicious! Thanks for sharing Robyn.
I’m so glad you enjoyed it, Tamy! Thanks! xo
Excellent recipe. Grandkids that don’t like squash ate it up!
Isn’t that awesome that the grandkids ate it too?! I’m so happy you enjoyed it – it’s been a fav in our family for such a long time! xo
Im assuming i could use zucchini instead of yellow squash?
I’m about to try halving the recipe and plan to use diced yellow squash and diced zucchini. Can’t imagine that it’ll be anything but great!!
This is an easy and very good squash casserole.
This is the best recipe. Everyone in my family love it!
So glad to hear that Sandy! xo
After reading the reviews with all the positive comments i am going to make this today and then will give my yeah or nay.
It is amazing. Made it twice in one week. My husband and I love it.
Wonderful, Dianne! Thanks so much! xo
This recipe is a keeper. I like the mild flavor and that the ingredients are what is usually already in the refrigerator. I did use all the butter to saute, added paprika and parsley to the squash as it was cooking and also the salt and pepper. Removed the pan from the burner and let it cool while the oven heated, and then mixed the milk, eggs and cheese in a one quart measuring cup, then stirred it into the pan. Came out delicious. Thanks for such a good recipe.
Thanks so much Hollie! xo
This recipe is a perennial favorite for the holidays. It is quite close to the long-time family recipe that my Mother passed down to me years ago. Over the years, I’ve improvised based on what’s on hand as well to experiment with different flavors. Sometimes I combine zucchini squash and the summer squash and onions and add bit of garlic to the saute; sometimes I steam the squash & onions then add a bit of garlic powder or granulated garlic to the egg & milk mixture. Sometimes, I add a bit of sour cream to the egg & milk mixture. If no, Ritz cracker, I’ve used breadcrumbs or Saltine crackers or even finely crumbled store-bought stuffing mix. Thanks Robyn – I love your recipes!
Thanks so much! I am happy you enjoy the recipes. xo
Absolutely the best to make, serve, freeze…just delicious all around!!! Thanks so much.
Thank you so much Jill! xo
Do you need to cover the casserole when baking for 45 minutes?
Hi Brooks,
You do not cover the casserole. Hope you enjoy it! Thanks!
I ❤️ squash casserole and I think I make it differently each time. Made this today for church potluck and people asked for the recipe. I used a bit more butter and cooked the fresh squash down a little more but it was a hit. Thank you!
Thanks Tammy! xo
Can I double this recipe? I’m hosting a large crowd at Thanksgiving.
Hi Carol,
You can certainly double the recipe if you wish. I often just make two dishes (or divide the doubled recipe into two dishes) of it when feeding a crowd so that each bite has a good ratio of that crunchy delicious topping. I hope you enjoy it! Thanks!
In the directions, it didn’t say anything about the cheese. So I forgot to put it in. Hope it still tastes good.
Sabine, I’m sorry you missed that. Instruction 3 states to add the cheese and milk and whisk into the eggs.
Can this be refrigerated uncooked without t hd e crackers, then bake the next day?
Yes, you can do that SD. Enjoy!
Finally a squash recipe without shredded carrots, sour cream, and Campbell cream of chicken soup. So excited to try today for a gift. Basic like my Mom used to make.
Thank you for posting recipe. Will especially be handy with my summer garden.
Also I love your Dutch oven I keep seeing in videos. Can you give me brand name, please? Thank you.
Hope you enjoy the recipe, Joli. I use Le Creuset or All-Clad Dutch ovens.
In the past I’ve added sour cream and cream of chicken soup to squash casserole. When I completed this recipe and prepared for freezer, it dawned on me that I had not added either one and reviewed the recipe to make sure I had followed the steps. The additions of sour cream and soup makes this very rich – almost too much. How does this compare? Also, the liquid mixture is thin. The picture looks perfect. After cooking and setting does the casserole liquid thicken? Sorry so long. Thank you.
Hi Cinda,
I’ve always made my squash casserole by this recipe and have never made it with those ingredients you’ve mentioned, so I can’t say how they compare. Except I can say I don’t find my recipe to be thin. This recipe has been in my family for generations and is one of our favorites. Hope you enjoy it! Thanks!
My wife and I made the squash casserole it was very good,I have leftovers can I refrigerate it or freeze it
I made this for Easter lunch & it was a hit. This dish will be a new holiday tradition! I made it just like directions said. Easy & yummy! Thanks for sharing Robyn!
Thanks, Sarah!
So glad you liked this! xo
I made this tonight, and my family loved it!!
Hi Lori,
I’m so glad your family loved this. It is a family favorite at my house! Thanks!
Since I live alone, I make recipe very similar to this, and line foil pie pans with foil, spray, add the squash mixture, wrap with clear wrap, then with heavy duty aluminum foil and freeze them. Then, when I want to use them,I sprinkle with cheese and sometimes cracker crumbs, bake uncovered from frozen, until done to my likeness. I like the thinness of them, better than the deeper casserole dish. They are incredible! Could make entire meal of it!! This recipe makes about 3 pie pans.
This is my favorite squash casserole recipe. I prepare several and freeze. I give as gifts with the recipe to highlight how to thaw and bake, along with a sleeve of a Ritz crackers.
People who come to dinner are always asking for the recipe.
Thank You
Hi Laurie,
What a great idea to give these as gifts. I’m so glad you love this recipe so much! Thanks!
Can’t thank you enough for sharing this fantastic recipe. Have looked for one for so long and to finally have found yours is like a gift sent from heaven. As it is just two of us (kids are all grown and on their own now), I’m looking forward to cutting this in half and enjoying it with my best guy! Thank you again and God bless you!
I hope the two of you enjoy this casserole, Sharron. It has been a favorite in my family for years. xo
This was amazing! Absolutely a hit and it will be made frequently! Yum!
So glad you liked the casserole, Kathy. It is always a hit at my house.
Do you peel the yellow summer squash for this recipe?
No, I don’t peel the squash, Sheryl. Hope you enjoy the casserole.
Can I make ahead and cook later?
These are the instructions under Make Ahead Squash Casserole in my post: Prepare casserole according to the recipe instructions, except wait about adding crushed Ritz cracker topping. Wrap uncooked casserole well with freezer wrap before freezing.
Thaw casserole overnight in the refrigerator the night before serving. Add crushed Ritz crackers to top of thawed squash casserole and bake according to recipe instructions. Hope you enjoy!
Could you make this with zucchini instead of yellow squash?
I have not made this with only zucchini, Shirley, but it is delicious with zucchini added with the yellow squash. Others have commented that they make is sometimes with substituting zucchini for the yellow squash and love it.
