Mashed potatoes is a total comfort food, and also a staple dish at many holiday meals. A knish upgrades everyone’s favorite side dish into its sophisticated cousin by stuffing it into a crusty outside. 

Go outside the expected, and welcome Autumn, by swapping the original flaky dough with my colourful antioxidant-rich sweet potato crust.

It’s pretty, the colours contrast wonderfully when sliced, and man, this tastes great!

This recipe does take a bit of time to make (there’s making the dough, and the filling, plus assembling it), but it’s always super popular, so I only make it for Fall special occasions! 

Assembling mashed potatoes on dough

Microwaving the sweet potato instead of boiling it can cut down on some time. Depending on the size of your potato, it can be ready in 4 minutes to 16 minutes. Peel it after microwaving, and it’s so much easier – the peel just slips off!

Save the water used for boiling the other potatoes, and use it to make super smooth and creamy mashed potatoes
