Hasselback or "Swedish-style" potatoes (Slideshow version)
Stage 12/12 :
Serve on their own, or with a green salad, for example.
Remarks
This 2-step cooking method takes a little longer, but you'll get much better results than with raw potatoes topped with cheese and ham before going into the oven.
This is a recipe that can be adapted to just about any taste: you can change the cheese and meat as you like. You could even replace the ham with vegetables, such as grilled zucchini slices.
If you prefer, replace the clarified butter with oil.
