Step 1: Preheat your oven to 425°F (220°C). A hot oven is crucial for getting those crispy edges on your fingerling potatoes.
Step 2: Wash the fingerling potatoes thoroughly under cold water to remove any dirt. Cut off any blemishes. Slice them in half lengthwise or leave them whole, depending on your preference.
Step 3: In a large mixing bowl, combine the melted butter, minced garlic, garlic powder, and salt. Stir until well combined.
Step 4: Add the prepared fingerling potatoes to the bowl with the garlic butter mixture. Toss gently until fully coated.
Step 5: Spread the coated potatoes in a single layer on a baking sheet. For easier cleanup, line the sheet with parchment paper. Roast for about 25-30 minutes, until golden brown and fork-tender, tossing halfway through.
Step 6: Remove from the oven, transfer to a serving dish, and sprinkle with chopped parsley if desired. Serve warm and enjoy!
