A Thanksgiving Favorite

Confession: As a kid, I scraped the marshmallow topping off this Thanksgiving side dish and left the best (and healthiest) part behind—the creamy sweet potatoes

After discovering just how enjoyable sweet potatoes are, I think the sweet potatoes are my favorite part of the dish! No matter which part is your favorite, you are going to love this combination. Not a fan of marshmallows, try our similar sweet potato casserole with a coconut and pecan topping.

I don’t know why we only make sweet potatoes during the holidays. It really is good enough to eat all year round.

Ingredients

Ingredients needed to make Sweet Potatoes with Marshmallows: Canned yams, mini marshmallows, butter, egg, brown sugar, salt.
  • Canned Sweet Potatoes: This is a short-cut for a busy Thanksgiving morning. You can also use freshly mashed sweet potatoes.
  • Mini Marshmallows: The fresher the better! Check to make sure the marshmallows can move freely in the bag, and they aren’t stuck together in a blob.
  • Additional Ingredients: Butter, brown sugar, salt, egg.

  1. Serve warm. It’s a little tricky to cut into serving sizes. I recommend using a knife to cut through the toasted marshmallows – not a serving spoon.

Recipe Tips and Variations

Make it up to 2 days ahead: This is one of the many reasons I love this recipe. The more prep before Thanksgiving day, the better! Prepare the sweet potato mixture and spread it in the baking pan. Cover with baking pan lid or plastic wrap and store in the fridge. When ready to serve, bake as directed, then add the marshmallows and toast just before serving.

Use fresh sweet potatoes: Peel and dice 6 medium-sized sweet potatoes. Boil until fork-tender, drain, then mash, and add the remaining recipe ingredients.

Make it vegan: The egg can be left out to make this vegan. It will make a slight difference in the texture, but the taste will be the same.

Extra toasty marshmallows: To get more of a toast on the marshmallows, put the dish under the broiler the last couple of minutes of baking. Keep a close eye on them so they don’t burn.

Feeding a crowd? This recipe can easily be doubled and baked in a 9×13 dish to serve up to 16 people.
