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.

From the Add a Pinch recipe archives, originally published 2013.
I just made this recipe and my dad and I loved it. As I didn’t want to purchase a gallon of milk, I substituted half and half, which added some extra richness to the dish. I also included the cayenne pepper, optional to the recipe, which I think added just the right flavour.
Thanks for the great recipe, Robyn.
I’m so glad you and your dad loved this casserole, Jake. I love it with the cayenne pepper, too. Thanks!
Hello, Robyn it’s Jake again.
This is an addendum to a review I posted on 8/29/20.
Your yellow squash casserole has become a tremendous hit in our household. Every time I turn around, my dad says, “why don’t you make the squash casserole again?” I’ve made it so many times, I’ve memorized the recipe. I did change one thing, I double the recipe. Everything still fits in a 9 in. X 13 in. casserole dish, although, I have to cook it for at least an hour.. Additionally, I add just a pinch of nutmeg, which makes a perfect dish a little more interesting.
Robyn, your squash casserole is sheer perfection. Again, thanks. Jake
Jake, I’m so happy your family, especially your dad, loves this casserole so much. Thanks.
Made this for side dish for company,everyone loved it!!! Thank you for sharing your Super easy and delicious recipe!
I’m so glad everyone loved it, Brenda. Thanks!
can I use eggbeaters for this recipe
I haven’t made this casserole with egg beaters, Sally, but I don’t see any reason it would not work. Hope you enjoy!
Sally, I used egg beater for the first 3 ingredients (squash, onions, egg), then beat the flour in by hand. Didnt add red pepper, but would have beat that in by hand as well.
Could you make this with zucchini instead of yellow squash?
I have not made this with only zucchini, Shirley, but it is delicious with zucchini added with the yellow squash. Others have commented that they make is sometimes with substituting zucchini for the yellow squash and love it.
Do you peel the yellow summer squash for this recipe?
No, I don’t peel the squash, Sheryl. Hope you enjoy the casserole.
Can I make ahead and cook later?
These are the instructions under Make Ahead Squash Casserole in my post: Prepare casserole according to the recipe instructions, except wait about adding crushed Ritz cracker topping. Wrap uncooked casserole well with freezer wrap before freezing.
Thaw casserole overnight in the refrigerator the night before serving. Add crushed Ritz crackers to top of thawed squash casserole and bake according to recipe instructions. Hope you enjoy!
This was amazing! Absolutely a hit and it will be made frequently! Yum!
So glad you liked the casserole, Kathy. It is always a hit at my house.
Can’t thank you enough for sharing this fantastic recipe. Have looked for one for so long and to finally have found yours is like a gift sent from heaven. As it is just two of us (kids are all grown and on their own now), I’m looking forward to cutting this in half and enjoying it with my best guy! Thank you again and God bless you!
I hope the two of you enjoy this casserole, Sharron. It has been a favorite in my family for years. xo
This is my favorite squash casserole recipe. I prepare several and freeze. I give as gifts with the recipe to highlight how to thaw and bake, along with a sleeve of a Ritz crackers.
People who come to dinner are always asking for the recipe.
Thank You
Hi Laurie,
What a great idea to give these as gifts. I’m so glad you love this recipe so much! Thanks!
Since I live alone, I make recipe very similar to this, and line foil pie pans with foil, spray, add the squash mixture, wrap with clear wrap, then with heavy duty aluminum foil and freeze them. Then, when I want to use them,I sprinkle with cheese and sometimes cracker crumbs, bake uncovered from frozen, until done to my likeness. I like the thinness of them, better than the deeper casserole dish. They are incredible! Could make entire meal of it!! This recipe makes about 3 pie pans.
I made this tonight, and my family loved it!!
Hi Lori,
I’m so glad your family loved this. It is a family favorite at my house! Thanks!
