Hasselback Potatoes (or accordion potatoes) were first introduced in the 1700s by a restaurant located in Stockholm named Hasselbacken. I found several variations for this recipe, and I decided to play around a little. The next time you want to impress company, these take just a few minutes to prepare. They're versatile, too. You can even add cheese in between each slice, for extra gooey deliciousness!
Line a Baking sheet with either foil, parchment paper or a silicone mat.
Using a wooden spoon, “cradle” the potato. The bowl of the wooden spoon will act as a guide so that you can cut 1/8-inch thick slices, without cutting all the way through.
Melt the butter and whisk into the oil.
Lightly brush the mat with the olive oil/butter. Drizzle the remaining (or brush on) oil & butter onto each potato.
If using the sliced garlic, insert one or two cloves into each potato.
Season with salt & pepper. Lay the thyme sprig (or you can use dried herbs, to your preference) and bake for 1 hour to 1 hour and 20 minutes.
These potatoes should turn out crisp on the outside and tender on the inside.
