Boston Yellow Squash Casserole

READY IN: 50mins
Recipe by Expat in Holland

This is a lovely squash dish that was given to me by my friend Lisa in Boston. You may easily substitute zucchini for yellow squash. It can be put together ahead of time, and baked before serving. It is one of my dad's favorite squash dishes that I have made.

I made this as directed and thought twice about it. I think I would have enjoyed this more if I had sprinkled the bread crumbs on top of the final casserole and drizzled it with butter. It turned out rather thick and I think the breadcrumbs distracted from the flavor of the fresh squash when mixed together. Flavors were excellent. Thanks for sharing. Made for I Recommend Tag Game :)
