FAQ's
The best way to avoid a watery casserole is to drain the cooked squash in a colander. This will remove any excess water that has been released during cooking. You can also pat the cooked squash with a paper towel to remove any additional moisture.

Yes, crookneck squash and yellow squash are the same things. They are both just different varieties of summer squash.
No, you do not have to peel squash for this recipe. The skin is edible and will just soften during cooking.
Things to know
- Spray your baking dish well with cooking spray. This will help to prevent the casserole from sticking.
- Slice the squash into even-sized pieces, so they cook evenly.
- Be sure to drain the squash well after cooking. You don't want excess liquid in your casserole.
- This casserole can be made ahead of time and reheated. But, I recommend adding your cracker crumbs to the top right before you bake it so that it doesn't get soggy.
- Sprinkle parmesan cheese over the top of the casserole for an extra cheesy flavor.
Variations
- If you don't have yellow squash, you can use zucchini squash instead!
- I like to use Cheese It crackers for this recipe, but you can really use any type of buttery cracker or even bread crumbs.
- If you want a little extra flavor, you can add some garlic to the squash while it is cooking.
- Add more veggies to this easy squash casserole by sauteing some diced bell pepper with the squash and onions.

- For a meaty version, add some cooked and crumbled bacon to the casserole.
- Make this into a main dish by adding cooked and shredded chicken to the casserole.
Storage
Refrigerate - Store leftover squash casserole in an airtight container for 3-4 days.
Freezer - Freeze in a freezer-safe dish for up to 2 months. Thaw overnight in the refrigerator before reheating. I recommend freezing without the cracker topping on top.
Reheat - Preheat the oven to 350 degrees. Place the casserole dish on a baking sheet (in case of bubbling over) and bake for 15-20 minutes or until heated through.
