Southern Squash Casserole is a classic summer dish perfect for using up all those squash from the garden. This classic casserole is a tasty side dish but is hearty enough to be the main course too!
Squash is one of my favorite vegetables. Growing up my Grandma would make this Squash Casserole often and I couldn’t get enough of it. Cheesy squash filling is topped with a buttery Ritz cracker topping, my mouth is watering just typing about it!
If you like Southern food you might also like my homemade biscuits and sausage gravy, shrimp and grits, or Southern collard greens!
How to Make Squash Casserole
There are so many variations of this recipe, but this is my grandma’s version so I’m partial to it. (Full printable recipe at the bottom of the page.)
You will need:
- squash
- Vidalia onion
- cream of mushroom soup
- mayonnaise
- egg
- cheddar cheese

- Ritz crackers
- butter
- Start by slicing the squash into quarter inch pieces.
- Then you’ll combine everything but the crackers and butter and mix it together.
- Pour the mixture over the squash and stir to coat. Make sure you get all that tasty squash covered!
- Pour the squash mixture into a casserole dish.
- Crush the Ritz crackers. I crush mine right in the sleeve (making sure the end doesn’t bust open, but you can also place them in a gallon bag and crush them. (The kids love helping with this!) They don’t need to be crushed super finely, just enough to crumble.
- Put the crumbs in a bowl and pour melted butter over them.
- Stir to mix. Sprinkle the cracker over the casserole and bake 35 minutes, then cover with foil for an additional 10 minutes.

Tips for best results

FAQs
This is a great casserole to prep ahead of time and freeze. Simply assemble the casserole without the Ritz crackers, warp well, and freeze unbaked. Thaw overnight in the refrigerator, then let it sit 20 minutes at room temperature before adding cracker mixture to the top just before baking according to recipe instructions.
Yes, you can use zucchini instead of yellow squash in this casserole. You can also use a combination of both!

I would love to print your recipes, but when I use the print function, it just starts adding in the adds and everything on the side and all the junk. Is there a way to just get a clean version; no pix or anything?

Hi Penny, Unfortunately I can’t control that but I will put the guidance out to the developer who made the recipe card functionality to see if they can make an image-free printable version and option. Thank you for the feedback!
