Preheat the Oven: Preheat your oven to 350°F (175°C).
Prepare the Pineapple Glaze: In a saucepan over medium heat, combine the pineapple juice from the can (reserve the slices), brown sugar, honey, Dijon mustard, and ground cloves. Stir until the brown sugar is dissolved and the mixture begins to simmer. Reduce the heat and let it simmer for about 5 minutes, stirring occasionally, until it thickens slightly.
Arrange the Ham: Place the sliced ham in a large baking dish, slightly overlapping the slices. Arrange the pineapple slices on top of the ham. If using, place a maraschino cherry in the center of each pineapple slice for a festive touch.
Apply the Glaze: Pour the pineapple glaze evenly over the ham and pineapple slices, using a basting brush to ensure the ham is well coated.
Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 15-20 minutes, basting occasionally with the glaze, until the ham is heated through and the glaze is caramelized.
Rest and Serve: Let the baked sliced ham with pineapple glaze rest for 10 minutes before serving.
