Today I am sharing my recipe for Squash Casserole. This is one of my all-time favorite side dishes that I make at least twice a month.
Now I know a lot of people do not care for squash at all, but to me it is heaven! This dish is a holiday and pot luck staple in the South. If you like squash, cheese, and crackers, this yummy side dish will be a winner for you! Here is our version. I hope you enjoy it as much as we do.
What kind of squash can you use?
Yellow squash is best when making this recipe. You can also use zucchini or butternut instead of yellow squash. I have made this recipe with yellow squash and zucchini together. I use a large 2lb bag of frozen yellow squash or 5-6 fresh yellow squash when they are in season.

Ingredients
- 1 32 oz bag of frozen yellow squash, or 5-6 large sliced fresh yellow squash, 2 lb
- 1 large onion, sliced and roughly chopped
- 2 tbsp butter
- ½ cup sour cream
- ¼ tsp salt
- ¼ tsp pepper
- ½ tsp dried minced garlic
- 1-2 cups grated cheddar cheese
- 1 sleeve Ritz Crackers crushed
Instructions
- Preheat oven to 350 degrees F.
- If squash is frozen, thaw in the microwave in a covered dish with 2 tablespoons of water. If using fresh squash slice and place in a deep skillet pan.
- Saute the squash and onion in 2 tablespoons of butter over medium-low heat. Cover and simmer until squash has almost softened and completely broken down, {about 15 minutes for frozen to 20 minutes for fresh}.
- Drain the squash and onions.
- Place the cooked squash in a colander, on top of a bowl to catch the liquid, then take another small bowl or potato masher and press down to squeeze excess moisture from the squash. You need to remove the moisture or the casserole will be runny.

- Pour mixture into a greased casserole dish and top with remaining cheese and cracker crumbs.
- Bake for 25-30 minutes.

It was perfect. Easy and delicious. This is now my go to squash casserole. Thanks for sharing it. It reminds me of my Granny’s recipe. We are from south GA
Glad you liked it Melissa, I am from North Florida (aka south Georgia) and that is our go to recipe. We put butter and crackers on everything, lol.
Didn’t have enough frozen left so I added a can of Rotel and a small can of diced hatch chilies to the yellow squash…first time added bar-b-que fritos and kids loved it. Second time just added ritz and the hubby and I liked it better.
Yum. I love a good squash casserole. I prefer the fresh squash so I’m glad you included the amount of fresh squash needed. Thanks for sharing on Marvelous Mondays. Pinning and sharing on my Facebook page! :)
this looks so yummy. i’ll have to see if i can find a similar frozen squash here in new england. thanks for sharing.
My Mom and sister make a similar recipe for squash casserole for every holiday dinner. I believe they use a can of cream of something soup in it though. Thanks!
She has the recipe for the seasoning at the bottom of the directions. Just simple pepper, salt and garlic mixture. Any squash would probably work but yellow is best!
What kind of squash are you using? Can’t wait to try it!
I use frozen sliced yellow squash or 5-6 fresh yellow squash sliced.
