Smashed Sweet Potatoes

If you are tired of the same sweet potato casserole for Thanksgiving, try these smashed sweet potatoes with crispy sage butter instead. They are sweet and decadent in a different way, but just as delicious! And they are a side dish that can be prepped ahead of time too!

If you have enjoyed my traditional Smashed Potato Recipe, you will love this sweet potato twist on the same concept!

Step#1: Season the Sweet Potatoes

  • You'll slice the sweet potatoes in half, drizzle with olive oil and season with salt, pepper and a sprinkle of pumpkin pie spice.
  • If you live outside the U.S.A and can't get pumpkin pie spice you can make your own with my Homemade Pumpkin Pie Spice Recipe. Or you can substitute with cinnamon instead.
  • For more flavor I roast the sweet potatoes instead of boiling them.
  • You'll roast them until they are fork tender which will make them easier to "smash".

Step#3: Smash the Potatoes

  • Using a potato masher, gently smash each sweet potato half. You can do this right on the baking sheet.
  • The nooks and grannies that develop from the smashing, create nice divets for the browned sage butter in which to settle.
  • Spay some olive oil on the potato masher to prevent it from sticking too much to the sweet potato.

Step#4: Make the Sage Butter

  • You'll brown the butter in the pan, just until it's a soft amber color.
  • Then fry the sage leaves until crispy. This is the same technique I use in my Sweet Potato Gnocchi Recipe which is so good!
  • To add even more flavor to the browned butter I add maple syrup and orange zest. Two flavors that pair so well with sweet potato.

Step#5: Brush the Sage Butter

  • Brush each sweet poato with the brown butter and top with 1-2 crispy sage leaves.
  • Not only do the leaves look beautiful on the sweet potato but the flavor combination is so great too! I also add fresh sage to my Sweet Potato Biscuits which look just as beautiful.
  • Then place the sweet potatoes back in the oven to set the butter for 10-15 minutes.
