Twice-baked sweet potatoes are made easy using the food probe and steam in the Anova Precision Oven. Whipped with spices and butter, these flavorful potatoes get a crisp exterior and broiled top. Note: This recipe calls for four sweet potatoes but only stuffs and twice-bakes three of them—this extra potato is used for filling only. It’s important to select sweet potatoes that are close in size for even cooking. In the off-chance one or more of the sweet potatoes comes out undercooked after the first stage, scoop the flesh and microwave for 1 to 2 minutes for a fast fix. If you’d like to pipe the sweet potato filling into a decorative pattern, use an immersion blender to purée the filling instead of mashing. If you mash, there may be a few stray lumps that can clog the piping tip.

5. Halve and Cool

Slice the potatoes in half, lengthwise and let cool until you’re able to handle them. Using a spoon or melon baller, scoop out the flesh starting from the middle of the sweet potato and moving towards the edge. This prevents the skin from tearing. If possible, leave a small perimeter of unscooped flesh for structure. Add the flesh to a large bowl (see note).
