Step 1

Preheat your oven to 400-degrees and place a pie of tinfoil on the top rack. Scrub and pat dry the potatoes, prick each several times with a fork. Place the potatoes on top of the tinfoil and bake under fork tender, about 1 hour.

Step 2

Remove from the oven to a cutting board. Use an oven mitt to hold the potato while you slice each in half lengthwise. Let the potatoes sit for 10 minutes.

Step 3

Into a large mixing bowl, add the butter (cut into pieces). Scoop out the potato with a spoon and add it to the bowl. Discard the skins.

Step 4

Using a potato masher, break up the potatoes and incorporate the butter.

Step 5

Stir in the brown sugar and add a little of the milk at a time until you have the desired consistency. Season with salt and pepper.

Step 6

Transfer the mashed sweet potatoes into a baking dish with a lid. Add an additional pat or two of butter to the top (optional) and cover.

Step 7

These are ready to serve!

Step 8

However, if you want to serve them later, place the dish in the fridge. When you want to serve the potatoes, place the dish in an oven pre-heated to 350-degrees and bake until heated through.
