Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.

In a mixing bowl, combine pure maple syrup, vanilla extract, ground cinnamon, and fresh orange zest. Whisk until fully incorporated.

Cut the fresh rhubarb into uniform 2-inch pieces and arrange them in a single layer on the lined baking sheet.

Coat each rhubarb piece generously with the maple mixture using a brush or spoon.

Roast the rhubarb in the oven for 15-20 minutes, checking for tenderness at 15 minutes.

Remove from the oven and let cool slightly before serving warm.
