This creamy southern-style squash casserole reminds me of Sunday dinners in Grandma’s kitchen. It can be made in one large dish to pass around the table, or in individual ramekins to fancy it up. Either way, it’s a cozy and comforting dish!
Southern Squash Casserole
When I was a little girl, we traveled cross-country every summer to visit my Grandma Montgomery in West Virginia. She was a sweet little woman who loved to garden and rock on her screened-in porch. She would sit outside watching us with a serene smile, as we played in her expansive yard under the trees.
Grandma Montgomery passed away when I was sixteen, but I still have loving memories of her kneeling in her garden, covered with a floppy sun hat and a linen shirt, sleeves rolled up to her elbows… Or in her apron, cooking comforting garden-fresh dishes.
And always with that same smile of peaceful contentment.
There were several recipes she made that I looked forward to every time we visited.
Some of her specialties were baked ham, creamed corn, green beans with bacon, homemade biscuits, and squash casserole.
Perfect Southern Recipe
When Lt. Dan and I first moved to North Carolina, I made it my goal to learn southern cooking, as I remembered from my summer travels as a child.
Southern squash casserole was high on the list. I made a point to try it as often as possible, so I could figure out how to recreate this iconic regional dish the way grandma used to make it.
Easy Squash Casserole Tips
Some southern cooks dice their yellow squash for squash casserole and some slice it thin, so it’s more of a “gratin” dish. Some use day-old bread as the thickening agent and some use crumbled crackers.
After trying many variations, I’ve come up with my own squash casserole recipe that reminds me of grandma’s recipe, yet with a tad more punch.
My squash casserole has a smooth creamy texture, because I pureed the squash and onions into a fine pulp, then added sour cream and sharp aged cheddar.
I also took out all the filler ingredients to get down to the basics of thickening by adding Gold Medal Flour. I always trust the consistency of Gold Medals finely ground flour, and felt it was a much better platform to build on than old crackers or bread.
After adding some herbs and spices for the kick, this creamy, cheesy, thick, and hearty squash casserole was a huge success. Each individual serving is sprinkled with cornbread crumbs, so the top toasts up golden and crispy.
This is the perfect side dish for any hearty comforting meal… and would certainly warm some hearts at your Thanksgiving table this year.
I’m sure grandma would agree!

I used to make a squash casserole similar to this one every Thanksgiving and everyone always raved about it. Mine had a cheese and panko topping but I think the cornbread topping sounds even better. I didn’t use flour in my recipe and it came out very good. Just wondering what the purpose is for it in this recipe if you don’t mind my asking.
The flour acts as a filler to absorb the squash juices. :)
I’m totally adding this to my Thanksgiving dinner spread. It sounds fantastic!
I love how comforting it is@!! My kids loved it, too!
Yummy! My family is going to love this recipe! I can’t wait to give this a try! Looks so delicious and tasty! So excited!
