I love having a garden, but it can be so overwhelming when you reap a large harvest. All of a sudden, you have a zillion and one yellow squash, zucchini, tomatoes, and an assortment of other produce all ready to eat. The problem comes when you can’t possibly eat everything as quickly as you’d like or you start to grow tired of making the same meals over and over again attempting to use up your harvest.
This summer squash casserole recipe was the perfect recipe to help use up some of our harvest! eMeals* sent this recipe to us to be used as the main dish but because my hubs is a true carnivore, that wasn’t going to fly so I had to use it as a side dish, but nonetheless it was amazing and delicious.
So, if you’re looking for a delicious, frugal, and clean recipe to use up the squash, zucchini or onion from your garden, this is a must try!
