8 tablespoons (1 stick) butter, softened
1/2 cup extra-virgin olive oil 
1/3 cup finely chopped chives 
Kosher salt and freshly ground black pepper 
6 medium russet potatoes, scrubbed 


Step 1
Preheat the oven to 450 degrees F.

Step 2
Stir together the butter, olive oil, chives and some salt and pepper in a small bowl.

Step 3
Place a potato between the handles of 2 wooden spoons or 2 chopsticks. Slice the potato into thin slices, leaving 1/4 inch at the bottom unsliced; the spoon handles will prevent you from slicing the potato all the way through. Repeat with the remaining potatoes.

Step 4
Put the potatoes on a baking sheet and brush on the butter mixture, making sure to get in between all the slices. Bake until tender and crisp, 55 to 60 minutes.
