Sweet Potato Casserole for Passover

I almost served this for dessert.  American sweet potato casserole is a big head-scratcher to the rest of the world.  I've never researched where it came from, but probably the South.

For this version, I wanted to come up with a recipe that was pareve, since I was making turkey.  The "cream" options were almond or coconut milk, and I jumped at the coconut option.  I've done coconut and sweet potato before, so I knew this would work.  Coconut milk doesn't taste "coconutty" until you add a considerable amount of sugar, so I'm only adding a little here.

Side note, when I went online to find which brands of coconut milk were kosher for Passover, Trader Joe's came up first.  It has no stabilizing gums or other additives, and happened to be the lowest price point I've seen in a couple of years.  I'm still not a TJ's devotée, but I'm finding more of their products that can be used by someone who cooks from scratch.

I used canned sweet potatoes, but will give instructions for baked as well.  I also made a double recipe of what I'm posting.  Even with folks coming back for a second scoop, I had a few days of leftovers.  We'll call this four generous servings.

*1 29 oz can sweet potatoes or 1-1/2 lb fresh sweet potatoes
1/2 C coconut milk, lightly beaten to break up the fat
1 Tb brown sugar
1/2 tsp cinnamon
1/4 tsp nutmeg
1 egg, lightly beaten
*2 Tb chopped walnuts, optional
8-12 large (Passover) marshmallows

1.  If making from raw potatoes, scrub and pierce in several pieces.  Roast at 400º until cooked through and soft, about 1 hour depending on size and shape.  Allow to cool and scoop out flesh.  For canned, drain.

2.  Preheat oven to 375º.  In a bowl, coarsely mash potatoes.  If desired, you can purée or whip them.  I wanted texture and left some chunks.

3.  Stir in the coconut milk, brown sugar, cinnamon, nutmeg, and beaten egg.  Spread in an 8x8 or similar sized casserole.  Sprinkle top with the walnuts, if using.

4.  Bake for 30 minutes, until bubbling.  Remove from oven, top with marshmallows, and bake again until marshmallows are toasted.  Serve hot
