This recipe is fantastic!! I didn’t change a thing!! Delicious! This is the second recipe of yours that I made for Thanksgiving! I’m a fan and will now keep following you. Thank you so much for sharing!

Southern Squash Casserole

Southern Squash Casserole is a comforting side dish casserole, often served during the holidays, with tender, cooked yellow squash, onions,  sour cream, and cheddar cheese topped with crushed buttery crackers.

Growing up this Southern Squash Casserole was the only way I would eat squash. We only had it on holidays or church potluck dinners.

Southern Squash Casserole

If you grew up in the South, then you know what I’m talking about. It was a staple for big gatherings.

I remember the tender squash in a creamy sauce topped with the crunchy buttery topping. It was so good.

I think that the Southern Squash Casserole is one of those Southern Recipes that has been served for decades by generation after generation. Probably because yellow squash grows abundantly in the South during the summer.

However, this Squash casserole is not just for summer. It makes a great side dish for Thanksgiving and other holiday dinners as well.

Southern Squash Casserole

Another reason the Southern Squash Casserole is so popular is that it is easy to make. Just saute fresh yellow squash in butter or oil with some onions until both are tender.

Then combine with cheesy, creamy sauce.

Top with crushed buttery crackers.

Then drizzle melted butter on top so you have a buttery golden crunchy topping on top of the casserole.

Bake the Southern Squash Casserole in the oven until the casserole is heated through and the topping is a light golden brown color.

 

Then gather all your closest family and friends and serve this popular Southern Squash Casserole. It will be a hit.

    I didn’t have an sour cream and didn’t want to go to the store. I used some milk, mayonnaise and a bit of lemon juice as a substitute. It was fantastic!

    I made two casseroles.
    Can I freeze one ?
    If so, before I bake it, or after ?

      Hi Cindy,

      Congrats for making 2 casseroles. Yes, you can freeze one of the casseroles after you bake it.

    This came out sooo good. The key is definitely good quality cheese (I used Cabot Seriously Sharp) and did add a little Dukes to the sour cream. Yum!

        Can you make this with a combination of yellow squash and zucchini? Do you think that would turn out just as good? I’m mostly trying to keep a little more green on my thanksgiving menu, but I’m really in the mood for a casserole and this one sounds delicious.

    Great recipe! I have made this several times. Always a winner.
    The only thing I do different is fry bacon in the pot, pour some of the bacon grease in the casserole dish already rubbed with butter. Then sauté the onions & squash in the pot. I add real bacon bits to the squash & onion mixture. Gives it a very rich flavor.

      Hi Peggy,

      I’m so glad you like the recipe. The addition of bacon sounds delicious. Great idea.

    If I make it two days ahead of time, should I bake it, cool, and put in fridge or wait to bake it on the day I plan to serve it?

      Hi Kathy,

      To make it ahead of time, assemble it, except for the Ritz cracker topping. Cover and refrigerate until about 30 minutes before you bake it. Add the crushed crackers and then bake as instructed above.

      Thanks,

      Michele

      Hi Sandy,

      I’m glad you were able to continue your family tradition of having squash for Thanksgiving. Honestly, the reason I first started my blog in the first place was because we had lost the oldest generation of our family and we lost their holiday recipes along with them. So, this blog was a way to share our family recipes with family members across the country. Now we share them with lots of families. I’m so happy they are now your family recipes too.

      Happy Thanksgiving,

      Michele

    This really was my favorite version of this dish so far! Our daughter (13) made this as a side dish for dinner and it turned out flawless! We didn’t have enough sour cream, so we used what we had and used some plain Greek yogurt to make up the difference. It turned out great anyway! Thank you so much for a great recipe!!!

    How many cups of squash does this use?

    Reply

      August 15, 2021 at 6:25 pm

      If 1 whole yellow squash that is sliced equals about 1-1/2 cups, and this recipe uses 5 whole squash, then that is about 7-1/2 cups of sliced squash.

    Hi! Someone in my family has an egg allergy. Do you think completely omitting the egg in this recipe would ruin the texture or maybe an egg replacement could work?

      Hi Brittani,

      I have not tried it without an egg or with an egg replacement. I recommend checking with your family member, and/or dietitian for the best substitute for the egg that won’t trigger your family member’s allergies.

      Thanks,

      Michele

    I didn’t have any cheddar or pepper jack so I subbed “Fiesta blend” and added 1/4 tsp oregano…the flavors were fantastic!
