This Homestyle Squash Casserole is another way to use the abundance of summer squash in a most spectacular way. To make it, tender cooked squash and sweet onion are seasoned and mixed with flavorful additions to make it creamy dreamy and delicious. Baked until the top is golden and bubbly, it's ready to serve alongside your favorite entrees.
Homestyle Squash Casserole
Squash casserole is another dish that was regularly seen on our table when we were kids. My Dad typically grew the squash and It's the kind of garden comfort food that I learned to make as a girl, from my Mom. I absolutely love it, still. I've also noted that making squash this way seems to be one of those sumptuous squash side dishes that kids seem to like better than steamed vegetables. That's always a huge perk for me being a Mom of two hungry boys.
Can You Use Crackers for the Topping?
A resounding, yes! This squash dish can be topped with dry herb stuffing as I call for in the recipe, or crushed crackers such as Ritz or Club crackers. The casserole filling can be assembled in advance, then topped with the crumb topping just before baking, for a timesaver.
Don't Limit Summer Squash to Summer Only
While we most often think of yellow squash using the warm summer months, we're so blessed to have suppliers that make it possible to enjoy year-round. This casserole would be perfect for fall meals and Thanksgiving, too. It's a dish you'll find on our table anytime of year, it's a taste of the South in your mouth.

This was awesome! I didn't have the herb stuffing mix, so I used Ritz crackers. So flavorful and an excellent way to use a bumper summer squash crop! Thank you!

Ritz crackers are the perfect substitution, thanks so much!

Could you use Zucchini in place of the yellow squash, or mix them?
Melissa
Absolutely, either way works.

I didn't know what to expect from the title. You know I do not think I have encountered a squash casserole anywhere near this one. What a winner! No wonder it was a family favorite comfort food. I am going to introduce it to my family.
