Step 1

Preheat the oven to 400 degrees F.

Step 2

In a large bowl, toss the potatoes with rosemary, lemon juice, olive oil, salt and pepper.

Step 3

Arrange the potatoes cut side down on a sheet pan. Spread them out in a single layer, so the potatoes are not overlapping, and they are making direct contact with the pan.

Step 4

Roast the potatoes for 40-45 minutes until they are brown and crisp on the edges and soft in the middle. You should be able to easily pierce them with a paring knife.
