Ingredients
  

  • 3 pounds sweet potatoes scrubbed
  • ½ teaspoon salt
  • ½ lemon juiced
  • ¼ cup orange juice
  • ¼ teaspoon ground ginger
  • ¼ cup brown sugar
  • ¼ cup softened butter

Instructions
 

  • Prick the sweet potatoes all over with a fork. Microwave on paper towels or a plate for 20-25 minutes until very soft all the way through. (this can be done in advance!)
  • When the potatoes have cooled enough to handle, remove the skin and place the flesh of the sweet potatoes in a large bowl with the rest of the ingredients. Use a fork to lightly mash the potatoes into the seasonings, then taste the mixture and adjust the seasonings to your preference - add more of anything you'd like!
  • Spread the mixture into a small baking dish (mine was 8x8 for these pictures), and microwave for 10 minutes more to heat through. Or, bake at 350F for 20 minutes.
  • Serve with your favorite meal. Enjoy!

Notes

Make Ahead: This can be made ahead! Make the dish up to the last heating step, then keep in the fridge for a few days before you'd like to serve them. Allow a bit of extra time to heat them through, maybe 15 minutes in the microwave and 30 in the oven if they are coming straight out of the fridge.
This recipe is gluten free and vegetarian as written and can easily be made vegan by using vegan butter.
I love these as a side dish as well for regular meals; wonderful for meal prep and to serve with some marinated grilled chicken or similar.
