Sweet Potatoes with Horseradish

Scott Phillips

Servings: twelve.

This casserole can be baked ahead and reheated in the microwave at the last minute, thus freeing the overburdened Thanksgiving oven.


  • 5 medium (about 2-1/4 lb.) sweet potatoes, peeled and sliced into even 1/4-inch disks
  • 1/4 cup prepared horseradish, well drained
  • 2 cups heavy or whipping cream
  • Kosher salt and freshly ground black pepper

  • Heat the oven to 400°F.
  • In a large bowl, toss the potatoes with the horseradish and cream, making sure that they’re coated evenly. Season with salt and pepper. Spread the potatoes in a 10×15-inch baking dish—the potatoes should be in a thin, even layer and should be mostly submerged in the cream. Bake uncovered until the cream has reduced and thickened and the potatoes are soft and tender when pierced with a knife, 30 to 40 minutes. If making ahead, let the potatoes cool and then refrigerate; bring them back to room temperature before reheating.

Make Ahead Tips

To serve, reheat the potatoes on medium-low power in the microwave or in a warm oven just until warmed through (be careful not to use too high a heat or the cream could separate), 3 to 4 minutes in the microwave, or about 10 minutes in the oven.

    I wonder if instead of bringing it to room temperature before reheating if it could be put into a cold oven and reheated as the oven comes up to temperature so as not to break the sauce? I'll try it and report back.

    These are spectacular and my go to sweet potato recipe at Thanksgiving. These do not rely on a bunch of added sugar for flavor. The potatoes are sweet enough already. The creams gives the dish a lovely texture and the horseradish provides a nice contrast to the sweetness. If you have someone who is not a horseradish fan they will still like these.
