Preparing the Potatoes:
- Preheat your oven to 375°F (190°C). Grease a baking sheet and line it with parchment paper, then lightly grease the parchment paper and sprinkle it with breadcrumbs. This setup will help form the crispy crust.
- Cook the Potatoes: In a large skillet over medium heat, combine the heavy cream, minced garlic, thyme, salt, and pepper. Add the potato slices and gently stir to coat. Simmer until the potatoes are just tender but not fully cooked, about 10-15 minutes. Carefully drain the potatoes, reserving the cream mixture.
Assembling the Roll:
- Layer the Potatoes: On the prepared baking sheet, arrange the potato slices in a single layer, slightly overlapping, in a rectangle shape. Make sure the layer is even for uniform cooking.
- Add the Filling: Sprinkle the mozzarella cheese over the potatoes, leaving a small border around the edges. Distribute the ham evenly over the cheese, followed by the grated Parmesan and parsley.
- Roll It Up: Starting from one long side, carefully roll up the layered potatoes and filling, using the parchment paper to help lift and roll tightly. Once rolled, ensure the seam is on the bottom and tuck in any stray potatoes or filling.
Baking:
- Bake the Roll: Brush the top of the potato roll with some of the reserved cream mixture and sprinkle with additional Parmesan cheese, if desired. Bake in the preheated oven for about 25-30 minutes, or until the top is golden and crispy.
- Cool and Slice: Let the roll cool for a few minutes before slicing into rounds. This rest period allows the cheese to set slightly, making the roll easier to cut.
Serving Suggestions:
- Serve the Scalloped Potato Roll as a show-stopping side dish with your main course. It pairs beautifully with roasted meats, grilled vegetables, or as part of a festive holiday spread.
- Garnish with additional fresh herbs, such as chives or parsley, for a pop of color and fresh flavor.
Tips for Success:
- Thinly Slice the Potatoes: Use a mandoline slicer for uniformly thin potato slices, which will ensure even cooking and layering.
- Be Gentle: When simmering the potatoes in the cream, stir gently to avoid breaking them.
- Tightly Roll: Rolling the potato sheet tightly will help maintain its shape and ensure every slice is packed with flavor.
This Scalloped Potato Roll not only offers the comfort and taste of traditional scalloped potatoes but also brings a unique presentation and texture to the table. Its creamy interior, flavored with garlic and thyme, and the crispy breadcrumb-coated crust make it a memorable dish that’s as enjoyable to make as it is to serve and eat.
