Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
Peel and slice carrots into even sticks to ensure uniform roasting.
Toss carrots with olive oil, honey, thyme, salt, and pepper. Spread them on the sheet pan.
Roast the carrots for 10 minutes to begin caramelization.
Meanwhile, prepare the glaze by combining Dijon, honey, garlic, lemon, olive oil, and seasonings.
Remove the pan from the oven and push carrots to one side.
Add salmon fillets skin-side down on the empty side of the sheet pan.
Brush the honey Dijon mixture generously over the salmon.
Return pan to oven and bake for 12–15 minutes, depending on salmon thickness.
Remove from the oven once salmon flakes easily with a fork.
Garnish with fresh parsley and lemon wedges.
Serve immediately while warm and glazed.
