Recipe for Zucchini and Summer Squash Casserole:

First we need to preheat the oven to 350 degrees F. 

Next, cook the squash with some vegetable oil over medium heat until completely cooked down, about 15-20 minutes! 

We’ll need to remove the water from the cooked squash. Line a colander with a piece of cheese cloth or a tea towel, then put the squash into the colander and squeeze out the excess moisture. 

Now in the skillet cook the onion in the butter for about 5 minutes. 

Finally, remove from the skillet and mix all the ingredients together, leaving out the crackers, and pour the mixture into a greased casserole dish.
