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!

I made the squash casserole for Easter and it was amazing. My daughter is a vegetarian so I can never have enough of these winners in my recipe file. Thanks
Would this recipe work fine with zucchini too (instead of yellow squash)? Just thinking ahead to the abundance of zucchini I will have in my summer garden & this recipe sounds like it could be added to my good list of zucchini recipes 🙂
You could, but zucchini is a little bit more watery, so I would suggest scooping out the seeded center of the zuccs and then slicing up for the casserole. This removes some of the watery tendencies. Even better to mix both yellow squash and zuccs!
oh my heavens! I have never seen such a recipe…it looks amazing. I can see why it would be a staple! i think we Northerners need to adopt it as a new staple also.
Love comfort food casseroles! Need to get some squash!
I have also made the squash casserole using the herb dressing in the bag and the cream of chicken soup have also added grated carrots and bell pepper was very good
You don’t add the butter to the crackers before you top the casserole?
That is correct. Not in the mixture on the crackers. It’s a southern thang.
I hate to ask this question because I see so many people ask questions that are covered in the text, but when do you add the Ritz crackers?
Thanks so much, Pat for catching that. You add the Ritz crackers right before popping the squash casserole into the oven. I’ve updated the recipe to include that. I really appreciate you!!! xoxo
I made it and followed the recipe but it was dry. However, it had a good taste.
It was dry because you cooked it too long. 30 to 35 min @ 350 degrees is sufficient.
Before it good in the oven. ( on top of the mixture)
This sounds so divine and comforting!!! I bet my son would love it!
I tried squash casserole for the first time at a seafood place, Osteens, in st. Augustine. Since then I notice it on all southern menus 🙂 this looks delicious Robyn, I can see why it’s a family favorite! I want to make this!
Photo is beautiful, and I know it’s as good as it looks. Absolutely love squash casserole…..definitely pinning this recipe! Thanks for sharing.
Looks delicious! Great for Sunday dinners.
