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!

Just made this. My husband said “This is w keeper!” I agree. Followed your directions precisely. Thank you for another great recipe!
Nannette, don’t you just love it when your husband makes the statement “that’s a keeper’ regarding a dish you make? I’m so glad you both liked the squash casserole.
This is SO good even without crackers!! I had to make this GF for family so I made as is, just without crackers, and it was amazing. Delicious leftovers as well!! I will definitely be making this again!!
Thanks so much, Sydney. I’m glad you enjoyed this as a gluten-free dish.
This is a delicious recipe. I made it just as written and I will make it again and again, it is so good! Thank you!
Thanks, Joan, I’m so glad you enjoy this squash casserole. It’s been a favorite in my family for years.
I’m not sure if I did something wrong, but the texture of the egg, milk, and cheese mixture once cooked was pretty eggy. Has the happened to anyone? How can I correct it? Otherwise, this is yummy!
Jessika, you don’t cook the egg, milk, and cheese. You mix those ingredients until well combined then add the cooked squash and other ingredients and follow instructions in Step 3 and pour it all into a casserole dish and bake according to instructions in Step 4. I hope this helps.
If I double it, how long should I bake it? I made it for Christmas and everyone wanted more!
Jaclyn. I would bake it in 2 9 x 13 pans and just follow the recipe as written for baking time and temperature.
did not say to bake covered or uncoverd? I would assume uncovered
Victor, you bake uncovered until the top is lightly browned. I hope you enjoy!
I know it calls for but can I use half and half if I’m out of milk?
Christy, I haven’t made this with half and half but others have and loved it. Hope you enjoy!
I’ve made this and can’t wait to make again AND try some of the other scrumptious recipes I’ve seen. 😊
Dainette, i hope you find many more recipes you love just as much as the squash casserole. Thanks!
The recipe halved easily. I gave it a little colour under the broiler at the end. Very delicious!
So glad you enjoyed the squash casserole, Yaninne.
This was great!! Going to add it to my summer recipes!!!!!
Thanks, Sarah. So happy you loved this casserole.
