Step 1

Prep: Preheat oven to 420°F (220°C). Place a rimmed sheet pan in oven as it preheats, to heat up.

Step 2

Season potatoes: Carefully toss potatoes in a large bowl with olive oil, garlic powder, paprika, salt and black pepper. Make sure all potatoes are evenly coated.

Step 3

Add potatoes to baking sheet: Carefully remove preheated sheet pan from oven using oven gloves. Lightly coat with oil. Place seasoned potatoes on pan, cut side down, in a single layer. Tuck rosemary sprigs in between potatoes.

Step 4

Bake: Bake potatoes for around 25-30 minutes, or until tender on the inside and browned on the outside. Remove from oven and flip potatoes to face cut side upwards. Finish under the broiler for 1-2 minutes to achieve a well-roasted, browned finish.

Step 5

Garnish: Sprinkle hot potatoes with black pepper, sea salt flakes and fresh parsley, if you like. Serve immediately.
