Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a small bowl, whisk together maple syrup, soy sauce, Dijon mustard, vinegar, garlic, olive oil and pepper until smooth.
1½ tbsp maple syrup, 1 tbsp soy sauce, 1 tsp Dijon mustard, 1 tsp apple cider vinegar, 1 clove garlic, 1 pinch pepper, 1 tsp olive oil
Pat salmon fillets dry with paper towels. Place on the prepared baking sheet, skin‑side down.
2 salmon fillets
Brush salmon generously with the maple glaze, reserving about 2 tsp for finishing.
Bake for 10–12 minutes, or until salmon flakes easily with a fork and reaches an internal temperature of 125–130°F for medium‑rare (or 140°F if you prefer more cooked).
Brush with the remaining glaze right after baking for a glossy, flavourful finish.
