Use It Up in a Squash and Zucchini Casserole!

A few weeks ago Cohl started coming home with enormous grocery bags FULL of summer vegetables.  A local dentist has a summer garden and likes to bring his extra produce to Cohl’s office.

There is absolutely nothing better than fresh, homegrown peppers, tomatoes and summer squash!!  Do any of you have a summer garden growing right now?

Healthy Squash Casserole is the Answer!

One week Cohl came home and the bag was packed to the brim with yellow summer squash and zucchini.  It would be a sin to let them all go bad, so I had to brainstorm what I could do with all of that great produce.

Squash casserole has always been one of my favorite summertime side dishes.  This time I wanted to try to make a version of a healthy squash casserole that was still simple to make and baked in the oven.

Healthy Summer Squash Casserole Ingredients:

Sure, the cheesy and cream-laden squash casseroles taste ah-maaazing, but let’s be real… all of that dairy takes away the incredible flavor of the fresh summer squash!

The ingredients for this healthy summer squash casserole are pretty simple.  You probably have most of them in your kitchen already!

• Zucchini and Yellow Summer Squash (duh!)
• Olive oil, salt, and pepper
• Parmesan cheese
• Panko breadcrumbs –> these are my fave gluten-free breadcrumbs!
• Parsley
