Grease a 9x13 inch baking dish with a little non-stick spray or softened butter.
In a small bowl combine the brown sugar, cinnamon, and orange zest.
Toss the sweet potato slices in the melted butter. Lay a single layer of the sweet potatoes in the bottom of the casserole dish.
Sprinkle the layer with ⅓ of the cinnamon sugar mixture.
Place a second layer of sweet potato slices covering the gaps in the first layer. Sprinkle the layer with ⅓ of the cinnamon sugar mixture.
Finish with a third layer of sweet potato slices on top.
Pour the orange juice over the potatoes and sprinkle the remaining cinnamon sugar mixture on top.
Scatter the cranberries on top of the sweet potatoes
Cover the dish with foil and place in the oven to bake for 60 minutes.
After 60 minutes remove the foil and sprinkle the pecans over the top of the potatoes. Continue baking for 10-15 minutes or until potatoes are fork tender.
When they have finished baking, remove from the oven and let cool for 10 minutes before serving.

Notes
The size of a sweet potato can vary greatly so we’ve given you a weight measurement. You may need more or less. You want to create approximately 3 layers of sliced sweet potatoes in your casserole dish so we find it’s easiest to buy a few more than you think you’ll need and then see what it takes to fill your dish. If you have extras save them to make sweet potato casserole with marshmallows or simple Instant Pot sweet potatoes for a weeknight dinner.
