In a medium pan, saute the chopped onion and garlic until soft, about 5 minutes. Once the onion and garlic are soft, place them in the bottom of a 9×13 inch pan. Top with the sliced zucchini, then the yellow crookneck squash, potatoes, and finally the tomato slices. Sprinkle generously with salt and pepper. Place uncovered in a preheated 450 F oven for 25-35 minutes. Test with a fork to make sure the potato slices are tender.

Take the casserole out of the oven and drizzle the cream on top of the veggies. Sprinkle the Parmesan cheese and fresh basil over the top and return to the oven for 15 more minutes. When done, the cream and cheese will bubble and melt. Let the casserole sit for a few minutes before serving.

I serve this with any meat main dish, or my favorite is serving it for breakfast with a fried egg on top with toast. It is the best meal when your garden is bursting with fresh veggies.
