Bring a large pot of water to boil on high heat.

Peel the sweet potatoes with a hand peeler.

Dice the potatoes into chunks and place them into the pot. Cook the potatoes for 20-30 minutes, or until the potatoes are fork tender.

Drain the potatoes over a colander.

Place the potatoes in a large mixing bowl and mash them with a hand masher or electric beater.

Then, pour the butter and milk into the mixture and continue mixing until creamy. Season with salt and pepper.

Scoop the mashed sweet potatoes into a bowl, sprinkle with chopped parsley and serve!
