sea salt flakes and freshly ground black pepper to taste
Instructions
Preheat the oven to 400 degrees F (200 degrees C).
Place 2 chopsticks on a cutting board with a potato lengthwise between the chopsticks. Slice the potato into 1/8-inch slices along its length, using the chopsticks as a guide so you don't cut all the way through. Repeat to cut remaining potatoes.
Insert 1 bay leaf inside each sliced potato.
Heat olive oil and butter in a roasting pan over medium heat. Add potatoes and garlic in a single layer and season generously with salt and pepper. Move potatoes around until coated all over and cook until browned a bit, 3 to 5 minutes.
Transfer the roasting pan to the preheated oven and roast until potatoes are crisp and golden, about 30 minutes.
