Spray the crockpot with cooking spray to prevent sticking.
Place the spiral-cut ham inside the crockpot, flat side down.
In a bowl, mix brown sugar, maple syrup, and pineapple juice.
Pour the mixture evenly over the ham, ensuring it seeps into the slices.
Cover and cook on low for 4-6 hours, occasionally spooning the glaze over the ham.
Once heated through, transfer the ham to a serving platter.
Drizzle extra glaze over the top and garnish with fresh herbs.
Slice and serve warm with your favorite sides.
