Place bacon in a large skillet and cover with 1/4-inch of water. Bring to a simmer over high heat. Cook, shaking pan occasionally, until water has evaporated and bacon begins to crisp. Continue cooking, stirring frequently, until bacon is browned and crisp all over, about 8 minutes total. Add potatoes, onions, heavy cream, and remaining tablespoon parsley and toss to combine. Season to taste with salt and pepper.
