Preheat oven to 425 degrees. Brush a large baking sheet with about half of the oil. Place the pan in the oven until hot, about 5 minutes.
Meanwhile, in a large bowl, toss together the sweet potatoes, paprika, salt, pepper and remaining oil. Remove the pan from the oven and carefully place the potatoes in a single layer on the hot pan.
Bake until tender, 18-20 minutes, turning once halfway through cooking.
While the potatoes roast, Cook the bacon in a large skillet over medium heat until crispy. Remove to a paper towel lined plate to drain.
Add the garlic to the pan and cook until fragrant, 1-2 minutes. Stir in the vinegar.
Place the cooked sweet potatoes on a large plate or platter and drizzle with the vinegar mixture. Sprinkle with the bacon, parsley and chives. Re-season with additional salt and pepper, if needed. Serve immediately.
