Made with tender pizza dough, savory ham, melty cheese, and a sweet and tangy glaze, this ham stromboli puts an irresistible twist on a classic ham sandwich.
Preheat the oven to 400℉ (205℃) and line a baking sheet with parchment paper.
Prepare glaze by whisking the juice of 1 small lemon, 2 tablespoons honey, and 1 tablespoon prepared horseradish together in a small bowl until well incorporated. Set to the side.
On a floured work surface or piece of parchment paper, roll out 1 pound pizza dough into a 8x12-inch rectangular shape. Brush the dough with a thin layer of the glaze, leaving a ½-inch border along the edges, and reserve the remaining glaze to use later.
Layer 8 ounces cheddar or swiss cheese (sliced or shredded) on the dough in a thin, even layer, leaving a 1-inch border around the edges of the dough. Add 8 ounces sliced ham over the cheese, overlapping the slices slightly.
Tightly roll the dough lengthwise, folding in the sides of the dough as you roll, until the seam is on the bottom and you have a log-like shape. Transfer the stromboli to a baking sheet lined with parchment paper.
Brush the surface of the stromboli with the remaining glaze and sprinkle with 1 teaspoon poppy seeds, if using. Using a sharp paring knife, make several 2-inch slits, spaced about 2 inches apart on the top of the stromboli, to allow steam to escape while baking.
Bake for 15 minutes. After 15 minutes, reduce the temperature to 375℉ (190℃) and continue to bake for 15-20 minutes, or until the stromboli is browned and the cheese is bubbling, and the center of the stromboli reaches 200℉ (93℃). Note: If you notice your stromboli browning too quickly, tent with foil and continue to bake until fully cooked through.
Remove the Stromboli from the oven and let rest for 15-20 minutes before slicing it into 1-inch thick slices for serving.
Notes
Ham: For the ham, use leftover thinly sliced ham or deli ham. Cheese: Use any sliced cheese you enjoy with ham. If not using the glaze, brush the dough with mustard or mayonnaise before adding the ham and cheese to add flavor, AND brush the stromboli with an egg wash or melted butter to help it brown up in the oven before baking. Leftovers: Store leftover slices in an airtight container for up to 4 days in the refrigerator. Reheat in the microwave if desired or enjoy cold.
