01 - Set the oven to 400°F and line a baking sheet with parchment paper.

03 - Pat the salmon fillets dry with paper towels and arrange them on the prepared baking sheet.
04 - Brush the top surface of each salmon fillet evenly with Dijon mustard.

07 - Remove from oven and serve immediately with lemon wedges.
