You can easily make this casserole in advance. Just bake the sweet potatoes without the marshmallows, cool, wrap tightly, and refrigerate. Just before serving, heat in a 350 F for about 15 minutes, then add the marshmallows and bake 5 to 10 minutes longer.


  • 5 large sweet potatoes (4 to 5 pounds)
  • 1/4 cup butter
  • 1/2 cup brown sugar (firmly packed)
  • 2 large eggs
  • 2/3 cup evaporated milk
  • 2 tablespoons ​orange juice
  • 1/2 teaspoon cinnamon
  • 1/4 teaspoon nutmeg
  • 1 (10.5-ounce) package miniature marshmallows

Steps to Make It

  1. Gather the ingredients. Preheat oven to 350 F.

  3. Wash and prick the sweet potatoes with a fork several times. Place on a baking sheet and bake 1 hour. Alternatively, place on a paper towel in the microwave and heat on high for 6 to 12 minutes until soft.

  4. Let potatoes cool. Peel and place sweet potato pulp in a food processor. A food processor will help the stringy parts of the baked sweet potatoes get smoothly mixed in. Alternatively, you could use a blender (though it's messier) or an electric mixer.

    Glass Bakeware Warning

    For premade casseroles or leftovers that are in a glass baking dish and have been refrigerated, do not place directly into a hot oven as the glass can shatter. Instead, place any cold glass bakeware into a cold oven to warm up while it preheats. Or, allow the bakeware to rest outside of the fridge for 30 minutes to reach room temperature while the oven preheats.

    Use Caution When Blending Hot Ingredients

    Steam expands quickly in a blender, and can cause ingredients to splatter everywhere or cause burns. To prevent this, fill the blender only one-third of the way up, vent the top, and cover with a folded kitchen towel while blending.
