Creating Crispy Garlic Butter Potatoes is a breeze when you follow these simple steps:

1. Preheat the Oven: Start by preheating your oven to 425°F (220°C). This high temperature helps achieve the perfect crispy texture.
2. Prepare the Potatoes: Rinse the baby potatoes under cold water and pat them dry with a clean towel. Halve them for even cooking.
3. Make the Garlic Butter Mixture: In a bowl, combine the melted butter, minced garlic, chopped rosemary, salt, black pepper, and red pepper flakes (if using). Mix well.
4. Coat the Potatoes: In a large mixing bowl, add the halved potatoes. Pour the garlic butter mixture over the potatoes, ensuring each piece is generously coated.
5. Arrange on a Baking Sheet: Spread the coated potatoes in a single layer on a baking sheet lined with parchment paper. Ensure they are spaced apart for even cooking.
6. Bake the Potatoes: Place the baking sheet in the preheated oven and bake for 30-35 minutes. Halfway through, give them a good toss to promote even crispiness.
7. Check for Doneness: The potatoes are ready when they are golden brown and crispy outside, and fork-tender inside.
8. Garnish and Serve: Once out of the oven, sprinkle fresh parsley and grated Parmesan cheese on top for added flavor.

These easy-to-follow steps ensure that you create perfectly crispy and flavorful potatoes every time.
