Ham and Cheese Rösti Recipe

Directions:

1. Beat egg in a large bowl. Stir in ham, 1/2 cup cheese, shallot, rosemary, pepper, and salt. Add frozen potatoes and stir to combine.
2. Heat 1 teaspoon oil in a large non-stick skillet over medium heat.
3. When oil is hot (test with a drop of water; oil should sputter, but should not be smoking), pat potato mixture into an even round in the pan. Cover and cook until browned and crispy on the bottom, 5 to 7 minutes.
4. Remove pan from heat.
5. Place a rimless baking sheet on top. Wearing oven mitts, grasp the pan and baking sheet together and carefully invert, umolding the rosti onto the baking sheet.
6. Wipe out any browned bits from the skillet.
7. Return it to the heat and add the remaining oil. Slide rosti back into the pan, browned side up.
8. Top with remaining 1/2 cup cheese, cover and cook the second side until crispy and browned, 4 to 6 minutes.
9. Slide onto a platter and let stand 5 minutes.
10. Cut into wedges and serve.
