Peel the sweet potatoes and slice them lengthwise into thin, even fries, about 1/4 inch thick.
Toss the fries on a baking sheet with the olive oil, salt, and pepper. Roast for 24–30 minutes, or until crispy on the outside and tender in the middle.
While the fries roast, mix the sour cream, brown sugar, olive oil, paprika, garlic, parsley, and salt and pepper until smooth and well combined. Transfer the dip to a serving bowl and garnish with a sprinkle of parsley or a drizzle of olive oil.
When the fries are done, sprinkle with parsley and serve alongside the dip. Enjoy!
