serves 8
1/2 cup butter, cubed
2 pounds red potatoes, cut in half
1 tablespoon minced onion, or to taste
2 tablespoons minced fresh parsley
1/2 teaspoon salt
1/4 teaspoon ground black pepper
Preheat the oven to 375 degrees F (190 degrees C). Place butter into a large baking dish and set in the oven while preheating.
Remove the baking dish from the oven. Add potatoes and onion and toss until thoroughly coated with butter; this will give them a nicely browned and slightly crisp coating.
Bake in the preheated oven until potatoes are tender, about 40 minutes. Remove from the oven and sprinkle with parsley, salt, and pepper. Toss until well coated.
