Squash Casserole features grated Cheddar cheese, crumbled buttery crackers, and fresh yellow squash. A favorite at potluck gatherings, this casserole is a great way to use those summer vegetables!
This Squash Casserole with Ritz crackers is ubiquitous on the Southern table in the summertime, probably because nearly everyone who has a garden grows squash and one plant produces about a million yellow squash. And don’t even get me started on zucchini!
If you’ve been to a church potluck or a classic meat-and-three diner anywhere in the South, chances are you happened upon some version of this yellow squash casserole, usually sitting next to a platter of meatloaf or good fried chicken.
Squash Casserole is made like most classic Southern dishes, with good, simple ingredients that your grandmother could get—nothing fancy!

Can you mix yellow squash and zucchini?
My family’s version of squash casserole uses only yellow squash, but you can absolutely substitute zucchini squash for all or some in this recipe.

How to make squash casserole
You’ll need to cook and drain the squash before putting it in the dish because yellow squash contains a lot of moisture. It takes just a few minutes to cook though, so don’t think you’ll be spending hours in the kitchen.
Step 1. Preheat the oven and butter a baking dish. I use a 9×9 square dish.
Step 2. Saute the onion and squash in a large skillet for about 10 minutes.
Step 3. Drain the squash mixture, making sure to release as much juice as possible.
Pro Tip: Using a paper towel, gently mash the squash and onion mixture in the colander so additional juice will drain out.
If you immediately see a lot of juice accumulate when you put the squash in the mixing bowl, put it back in the colander and drain again, then back in the bowl. I usually do this a couple of times.
Step 4. Add butter, eggs, milk, pimentos, cracker crumbs, and cheese and spread mixture in the baking dish.
Step 5. Sprinkle Ritz cracker crumbs and grated cheese as a topping and then bake for about 45 minutes.
Can you freeze squash casserole?
- Yes! Mix the casserole completely but do not add the Ritz cracker crumb topping and do not bake. Place in a freezer container (I LOVE these containers) or wrap your dish tightly with tin foil and freeze.
- When ready to serve, thaw the casserole overnight in the refrigerator. Add the cracker topping and bake as directed.

Squash Casserole
Ingredients
- 1 cup chopped Vidalia onion
- 2-3 lbs. squash sliced (you want about 2 1/2 cups cooked squash/onion mixture, so usually about 4-5 cups sliced uncooked squash)
- 2 large eggs
- 2 tablespoons diced pimentos
- 1 cup evaporated milk
- 1 ½ cups grated Cheddar cheese
- 2 cups buttery cracker crumbs
- 6 tablespoons butter divided (2 for skillet, the other 4 melted/divided)
- Salt and pepper
Instructions
- Preheat oven to 350. Butter a 2-quart baking dish (I use a 9×9-inch square dish).
- In a large skillet, melt 2 tablespoons butter, then cook the onion 5 minutes. Add the squash and enough water to barely cover and bring to a boil. Turn down to a simmer and cook just until squash is tender and liquid has evaporated.
- Drain the squash and onion mixture in a colander and then gently mash in the colander (using a paper towel) so additional juice will drain out. Place squash and onion in a large mixing bowl. If you immediately see a lot of juice accumulate then put it back in the colander and drain again, then back in the bowl. I usually do this a couple of times.
- Once the squash is adequately drained, add 2 tablespoons melted butter, eggs, evaporated milk, pimentos, 3/4 cup of cracker crumbs, 1 cup grated cheese, and salt and pepper. Mix well.
- In a separate bowl or large zipper bag, mix the remaining cracker crumbs with the last 2 tablespoons melted butter.
- Sprinkle the remaining 1/2 cup of grated cheese over the squash and then the cracker crumbs over the cheese.
- Bake for about 45 minutes, until top is golden brown.

Notes
