Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
In a bowl, toss the sliced carrots with olive oil, maple syrup, salt, and pepper. Spread the carrots evenly on the prepared baking sheet.
Place the salmon fillets on the baking sheet, nestled among the carrots. Drizzle the fillets with olive oil, then season with salt, pepper, and fresh thyme.
Bake in the preheated oven for 20-25 minutes, or until the salmon is cooked through and flakes easily with a fork.
Remove from the oven and let rest for 2-3 minutes before serving.
