Yellow Squash Casserole is a classic Southern side dish. Sliced squash is baked in a cheesy cream sauce and topped with a buttery cracker crumble. It is always a favorite!

How many cups are in a yellow squash?

Yellow squash vary in size. Size can vary amongst the different varieties (crookneck, straightneck, patty pans, etc) and garden picked squash can even be quite large. It is better to measure squash by the pound. 1 pound of squash should give you about 3 cups of squash to work with.

Is yellow squash like zucchini?

They are very similar vegetables, but they do have differences. Yellow squash tapers at the neck to form an elongated pair shape. The flavor of yellow squash is a bit sweeter than that of zucchini.

Can I substitute zucchini for yellow squash?

Yes you can! Zucchini is not quite as sweet, but you can still use it in place of any recipe calling for yellow squash.

Do I have to use Ritz crackers on top? What can I use instead?

Ritz crackers are a buttery cracker that melts in your mouth. Feel free to use generic brands of the same thing. If you cannot locate Ritz or a generic version, substitute a plain salty cracker.
