Mashed Yam Casserole

READY IN: 40mins
Recipe by Parsley

I love this! You can use sweet potatoes, but I prefer yams. No sugar or marshmallows in this. The sweetness comes from a banana. Great with ham or for Thanksgiving or anytime!

I really enjoyed this recipe when my MIL introduced it to me a few Thanksgiving seasons ago. I love the hint of banana in this dish. It adds the right amount of sweetness to the sweet potatoes (or yams). I will make it for Thanksgiving this year but with modifications since my daughter is allergic to dairy. I will use vegan butter (Earth Balance) and Toffuti sour cream.
