Ingredients

SWEET POTATOES Sweet potatoes and yams are different vegetables although the term is often used interchangeably. Sweet potatoes are softer and cook up creamier while yams are denser and have more starch. Choose sweet potatoes that are firm and heavy without and soft spots.

DAIRY Just like regular mashed potatoes, real butter and milk or cream makes them extra rich and flavorful. To keep them healthier, use a bit less butter and milk in place of cream.

VARIATIONS Make savory mashed sweet potatoes with garlic and onion and broth instead of water. For a sweeter version, use apple juice and a dash of cinnamon. Top with mini marshmallows and let them melt on the top before serving. Use Pumpkin Pie Spice in this recipe and other holiday favorites!

Recipe Tips

  • Drain the potatoes well to remove as much water as possible.
  • Add an apple or some chopped carrot or butternut squash to the potatoes before cooking.
  • Mashed sweet potatoes can be topped with marshmallows and then place the lid on a few minutes to melt or soften them.
  • Top with some chopped pecans. Lightly toast nuts in a sauté pan until they are barely golden. This intensifies the flavor and makes them extra crunchy!

How to Store Leftovers

Keep mashed sweet potatoes in a covered container in the refrigerator for up to 4 days. Add a little milk and reheat on the stove. Freeze in zippered bags with the date labeled on the outside up to 4 weeks.

  1. I made these for Thanksgiving yesterday. The cooking time was *perfect* in my IP. I ended up not adding cinnamon, but I did add a bit more brown sugar. I got multiple ‘best sweet potatoes I’ve ever had’ comments from my family. This is my new go-to!5 stars
