In a large mixing bowl, toss the halved baby potatoes with the melted butter, minced garlic, chopped rosemary, salt, pepper, and paprika until the potatoes are well coated.
Spread the coated potatoes in a single layer on a baking sheet lined with parchment paper for easier cleanup.
Roast in the preheated oven for 25-30 minutes, or until the potatoes are golden brown and fork-tender, tossing them halfway through for even cooking.
Once cooked, remove from the oven and transfer to a serving dish.
Drizzle any remaining garlic butter from the baking sheet over the potatoes and sprinkle with freshly chopped parsley for a burst of color and flavor.
