Preheat oven to 400 degrees F. Line two baking sheets with foil.
Skin potatoes and cut sweet potatoes lengthwise into 1/2-inch thick strips. Place sweet potatoes in a large bowl. Drizzle with butter then season with salt, pepper, garlic powder and nutmeg and toss to coat. Arrange sweet potatoes in a single layer on prepared baking sheets and bake for 10 to 15 minutes.
Turn potatoes over and bake for 10 to 15 minutes more or until golden brown and potatoes are tender.
Whisk butter and garlic powder together and drizzle over fries and serve.
Switch up the potatoes. This fry recipe works with any type of potato outside of sweet potatoes as well.
