Cheesy Hasselback Potato Gratin

Presentation is everything and that’s one of the things we love about this holiday potato mash-up of hasselback potatoes and potato gratin. Hasselback-cut potatoes nestled together, surrounded by a smoky, savory, creamy, cheesy sauce. What’s not to love?! Looks impressive, yet easy to make. To easily slice the potatoes, place 2 rulers or wooden spoons on either side of the potato to slice them evenly without cutting all the way through.

Cooking Directions

  • Heat the oven to 400°F.  Using a sharp knife, make crosswise cuts into the potatoes (1/8-to 1/4-inch apart) almost all the way through but leave the bottoms intact so that the slices stay connected at the bottom.  Arrange the potatoes in a 13x9x2-inch baking dish.  Fan the slices of the potatoes open slightly.
  • Heat the butter in a 3-quart saucepan over medium heat.  Add the onion and cook for 3 minutes or until tender, stirring occasionally.  Add the garlic, flour and half the rosemary and cook and stir for 1 minute.  Stir in the broth and heat to a boil.  Reduce the heat to medium-low.  Cook for 5 minutes or until the broth mixture is slightly thickened.  Stir in the heavy cream, half the Gouda cheese and the Parmesan cheese.
  • Pour the broth mixture over the potatoes, making sure the mixture gets in between the slices.  Cover the baking dish.
  • Bake for 40 minutes.  Uncover the baking dish.  Spoon the broth mixture from the bottom of the dish over the potatoes.
  • Bake for 20 minutes.  Sprinkle with the remaining Gouda cheese.  Bake for 5 minutes more or until the potatoes are tender and the cheese is melted and lightly browned.  Sprinkle with the remaining rosemary.
