I'm always trying to find new ways to use sweet potatoes, because my boyfriend loves them. This was a success - the tanginess of the yogurt sort of brightened up the mash. —Erin Jeanne McDowell

  • Prep time 10 minutes
  • Cook time 45 minutes
  • Serves 4-6
  • 3 large sweet potatoes, cubed (540 g)
  • 6 cloves garlic (30 g)
  • 3-4 Tbsp olive oil (45-60 g)
  • salt and pepper, as needed
  • 3/4 cup Greek Yogurt (170 g)
  • 5 tablespoons butter (71 g)
  • 1 tablespoon fresh chopped rosemary (3 g)
In This Recipe
  1. Toss the potatoes and garlic with the oil, salt, and pepper. Spread into an even layer on a baking sheet and roast in a 375 degree oven until tender and caramelized, about 30-45 minutes.
  2. Transfer the potatoes and garlic to a large bowl, and use a handheld mixer to whip them with the Greek yogurt until smooth.
  3. Melt the butter in a small saucepan, and add the rosemary. Let the butter rest until it is set. Top the warm potatoes with the butter.

I always have three kinds of hot sauce in my purse. I have a soft spot for making people their favorite dessert, especially if it's wrapped in a pastry crust. My newest cookbook, The Book on Pie, came out on November 10th, 2020, and my pie merch collaboration with Food52 is out now too:

Great recipe! Doesn't even need the rosemary butter.

I needed a quick last minute recipe for a Sweet Potato side that wasn't a cassarole and didn't contain any extra added sugar. This recipe was such a delight and a crowd pleaser. The natural flavor of the potatoes/garlic/olive oil combined with the Greek Yogurt, alone was a gem. But the Rosemary butter added quite the finishing bite.

Thank you so much for this. Will definitely make it again.
