Squash Casserole is an essential dish for family meals, holidays, and more. Topped with a buttery cracker topping, this squash casserole recipe is a delicious all-time favorite!
Squash Casserole is one of those recipes that you’ll find for nearly every holiday, reunion, or special occasion when my family gets together. I make it a lot in the summer when squash is fresh from my vegetable garden too.
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. This recipe is exceptionally delicious and frequently requested! If you are looking for more squash recipes, you may enjoy my oven-roasted squash, air fryer squash, and fried squash recipes. Yum!

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!
How to Make Squash Casserole
Preheat your oven to 350 degrees Fahrenheit. Melt 2 tablespoons of butter in a medium skillet or saute pan over medium-low heat. Add squash and onions and cook until tender.
Lightly whisk eggs in a large bowl. Add cheese and milk and whisk into the egg until well combined. Add cooked squash and onions to the egg mixture and stir well until just combined. Melt the remaining 2 tablespoons of butter in a skillet used to cook squash and onions. Add that melted butter to the squash casserole mixture. Add cayenne pepper, if using, along with salt and pepper. Stir well to combine.
Spray a 9×13 casserole dish with cooking spray and pour the squash casserole mixture into the baking dish. Top evenly with crushed Ritz crackers.
Place the casserole in a preheated oven and bake for 45 minutes, or until the top has been lightly browned and the casserole does not shake when the dish is moved.
Allow cooked squash casserole to sit for about 3 minutes before serving.
I enjoy serving this anytime as a side dish with chicken, pot roast or skillet pork chops. It’s great alongside mashed potatoes and so many more favorite sides.
Make Ahead
This casserole freezes beautifully!
Prepare casserole according to the recipe instructions, except wait about adding crushed Ritz cracker topping. Wrap the uncooked casserole well with freezer wrap before freezing.
Thaw the casserole overnight in the refrigerator the night before serving. Add crushed Ritz crackers to the top of the thawed squash casserole and bake according to recipe instructions. Enjoy!

Has anyone used butternut squash (the only type,of squash my family likes), instead for,this recipe? Did you make any adjustments to the recipe due to the different flavor and texture of the butternut squash?
I made it with butternut squash! Salted to taste (way more than recipe calls for) and added a bit extra butter (didn’t measure). I also threw in some Asiago and sprinkled some Parmesan on top with the crackers. I baked it for about an hour. Came out sublime 🙂
Autumn, thanks for letting me know how you made this casserole with butternut squash. I had never made it with that squash. I’ll have to try it sometime.
Can you double the recipe?
Great recipe! Also the pork recipe is great, doing it again tomorrow. Thanks.
I meant to rate this four stars as is, also wanted to add that I used dry herb stuffing mix for the topping to help offset the richness of the cream.
This looked like the base recipe I wanted, and it was perfect “everyday” squash casserole. Then I took it up a notch, trying to replicate a dish I had in Asheville. I diced up about 3 slices of applewood smoked bacon and used that, plus a bit of butter, to sauté the squash and onion. I also substituted light cream for the milk. The results were divine! And much better received by the boys in the house,
It’s tongue-in-cheek humor.
I dont have ritz crackers, what else could I use?
You can use any type of butter crackers or make your own topping by making bread crumbs and toasting them lightly in the oven with butter.
Is there an easy way to divide this so it can be a side dish for 2 people? Thanks!!
I have just made this. I did double the quantity as I have an abundance of squash. It’s a real winner. My goodness it’s good. Thank you so much
K we followed this and got a bread crust on top….why would it do that?
