01 - Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly oil it.
02 - Pat the salmon fillets dry with paper towels. Arrange them on the prepared baking sheet and season with salt and pepper.
03 - In a small bowl, whisk together Dijon mustard, honey, whole grain mustard (if using), lemon juice, olive oil, and minced garlic until smooth.
04 - Spoon or brush the honey mustard glaze evenly over the top of each salmon fillet.
05 - Bake for 12–15 minutes, or until the salmon is just cooked through and flakes easily with a fork (internal temperature should reach 145°F/63°C).
06 - Transfer to plates, sprinkle with fresh parsley, and serve with lemon wedges.
