FAQ's
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.
Deb's tips for the perfect casserole
Slice the squash into even-sized pieces so everything cooks evenly and tender. This casserole can easily be made ahead of time, just wait to add the cracker crumbs until right before baking so the topping stays crisp instead of soggy.
Variations for the Squash Casserole
- I like to use Cheese It crackers for this recipe, but you can really use any type of buttery cracker, Ritz crackers, Goldfish Crackers or panko breadcrumbs. All are good options!
- If you want a little extra flavor, you can add a pinch of red pepper flakes, or garlic to the squash, or diced bell peppers while it is cooking.
- For a meaty version, add some cooked and crumbled bacon or cooked chicken to the casserole.
