Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a large bowl, toss the carrots with olive oil, salt, and pepper until evenly coated.
Spread the carrots in a single layer on the prepared baking sheet.
Roast for 20 minutes, or until the carrots are tender and slightly browned.
Meanwhile, prepare the maple glaze. In a small saucepan, whisk together maple syrup, melted vegan butter, and dried thyme. Bring to a simmer over medium heat and cook for 2-3 minutes, or until slightly thickened.
Prepare the candied pecans. In a small skillet, combine pecan halves, maple syrup, cinnamon, and ginger. Cook over medium heat, stirring frequently, until the pecans are coated and the sugar is caramelized.
Remove the roasted carrots from the oven and brush them generously with the maple glaze.
Top with the candied pecans and serve immediately.
