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.

It is amazing. Made it twice in one week. My husband and I love it.
Wonderful, Dianne! Thanks so much! xo
After reading the reviews with all the positive comments i am going to make this today and then will give my yeah or nay.
Can this casserole be made the night before?
Chris, for future reference, there is a Make Ahead section in the post that explains steps to make this early. 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 is the best recipe. Everyone in my family love it!
So glad to hear that Sandy! xo
This is an easy and very good squash casserole.
I’m excited to try this recipe but I’m not excited about not having enough oven space for Thanksgiving and cooking at a higher temp. Any chance it might work somehow in a slow cooker, probably not I am guessing.
I haven’t tried making this in a slow cooker, Diane, so I can’t tell you how it will turn out.
Im assuming i could use zucchini instead of yellow squash?
I’m about to try halving the recipe and plan to use diced yellow squash and diced zucchini. Can’t imagine that it’ll be anything but great!!
Excellent recipe. Grandkids that don’t like squash ate it up!
Isn’t that awesome that the grandkids ate it too?! I’m so happy you enjoyed it – it’s been a fav in our family for such a long time! xo
I made this tonight. Delicious! Thanks for sharing Robyn.
I’m so glad you enjoyed it, Tamy! Thanks! xo
For KETO: I subbed the ritz crackers with crushed pork rinds, Added 1/4 cup heavy whipping cream and 4TBSP cream cheese. Made this two nights in a row. Delicious!!
Thanks so much for that tip, Teresa. I’m so happy you liked it! xo
I have made this a couple of times and it was a huge hit. I love this recipe.
It’s such a family favorite dish, so I’m so happy to hear that it was a hit for you too, Tammie! xo
Will be definitely trying this out today, adding a bit of fresh spearmint as well;) Thanx so much for the delicious recipe, greetings from sunny Greece!

It was fantastic! We sliced the squash using a mandolin to get thin slices and also tried a little Parmesan with it. Delicious, thanx for the delicious recipe!
