Prepare the Carrots: If using whole carrots, slice them diagonally into 1/2-inch thick pieces for even cooking. If using baby carrots, simply peel and leave them whole.
Preheat the Oven: Preheat your oven to 400°F (200°C).
Mix the Glaze: In a small bowl, combine the maple syrup, butter, olive oil, salt, black pepper, and ground cinnamon. Microwave for 20-30 seconds until the butter melts, then stir to combine.
Coat the Carrots: Place the prepared carrots in a large mixing bowl and pour the maple glaze over them. Toss until all the carrots are evenly coated.
Bake: Spread the glazed carrots on a parchment-lined baking sheet in a single layer. Bake in the preheated oven for 25-30 minutes, stirring halfway through, until the carrots are tender and caramelized.
Add Fresh Herbs: Remove the baking sheet from the oven and sprinkle fresh thyme leaves over the glazed carrots. Toss gently to combine.
Serve: Transfer the carrots to a serving dish and, if desired, sprinkle with chopped pecans for added crunch.
