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.
