Preheat your oven to 350°F (175°C). Remove the packaging from the ham and place it in a large oven-safe dish. Arrange the pineapple slices between the layers of ham.
Pour the pineapple juice over the ham. Sprinkle brown sugar on top of the ham and pineapple slices, adjusting the amount for your preferred sweetness.
Cover the ham with aluminum foil and bake for 1.5 hours, or until heated through. Baste the ham with its juices occasionally to keep it moist.
If your ham has a glaze packet, mix it with a little pineapple juice and brush it over the ham in the last 15 minutes of baking.
Once done, remove from the oven, let it rest for 5-10 minutes, then slice and serve with the pineapple slices.
