Sweet potato casserole

2 1/2 lbs sweet potatoes, peeled and cubed
3/4 cup brown sugar
1/4 cup butter
1 1/2 tsp salt
1/2 tsp vanilla
1/2 cup orange juice
1/2 cup chopped pecans (optional)
cooking spray
miniature marshmallows

Spray down pan/stone/crock with cooking spray.
Mix together the sweet potatoes, brown sugar, salt, vanilla, and orange juice (and pecans, if you choose). Pour into baking pan/stone.
Top with marshmallows.
If you're using a crock, like I had to because my oven was otherwise occupied, wait until casserole is thoroughly cooked, then throw the marshmallows on top. When they start turning gooey, serve.
