Yellow Squash Casserole is creamy and cheesy with a buttery and crispy Ritz cracker topping. It makes a delicious side dish and is perfect for using fresh summer squash.
Yellow Squash Casserole with lots of cheddar cheese and a buttery cracker crumb topping is one of my favorite casseroles to make during the summer months. It’s super creamy with tender slices of summer squash and onion. A combination of mayonnaise and sour cream gives it plenty of creamy flavor.
Serve Yellow Squash Casserole at a summer potluck or as a comforting side dish for a family meal. I love it with fried chicken. Actually, I think I love everything with fried chicken. 🙂
This recipe also makes a great holiday side. My som requests it every Thanksgiving and Christmas.
Yellow squash is plentiful at farmers markets in the south during the summer months and it is easily grown in a home garden so I tend to make this casserole frequently during the summer months. But a creamy casserole like this is also extremely comforting during the cooler months.
Yellow Squash Casserole Recipe Tip
This casserole is really easy to make. You do want to precook the squash some because you don’t want it to be crunchy at all in the finished casserole. You can either slice it and saute it, steam it, or even microwave it until just tender.

Excellent! I add half the crackers to squash mixture.
This is my favorite squash casserole recipe, delicious
Wow! This squash casserole recipe is absolutely DELICIOUS!
I grow a tropical type of squash called: Snake Gourd (Naga, Python Gourd, Doodhi, etc). Since I didn’t have any yellow squash on hand, I used my snake gourd instead and it turned out so tasty.
I’m thinking that this recipe would work well with Tromboncino squash or a zucchini squash variety.
Many thanks for sharing your recipe! 🙂
