Begin by peeling your sweet potatoes and cutting them into uniform chunks, about 1-2 inches. Place the chopped sweet potatoes in a large pot and cover them with water.

Set the pot on the stove over high heat and bring the water to a rolling boil. Once boiling, reduce to medium and let simmer for about 15-20 minutes until fork-tender.

Carefully drain the sweet potatoes in a colander, allowing excess water to evaporate. Return potatoes to the pot and mash until smooth.

Gradually pour in the olive oil and mix it into the mashed sweet potatoes. Add garlic, salt, and pepper according to taste.

Drizzle in milk or cream slowly until the desired texture is achieved, stirring continuously until creamy.

Taste and adjust seasonings as necessary. Garnish with chopped herbs before serving.
