01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease with cooking spray.
02 - Pat salmon fillets dry with paper towels and arrange skin-side down on the prepared baking sheet.
03 - In a small bowl, whisk together the chopped dill, lemon zest, lemon juice, olive oil, minced garlic, sea salt, and black pepper until well combined.
04 - Spoon or brush the dill-lemon mixture evenly over the top of each salmon fillet, ensuring full coverage.
05 - Arrange fresh lemon slices on top of the seasoned fillets if desired for presentation.
06 - Bake for 15 to 18 minutes, or until salmon is just opaque throughout and flakes easily when tested with a fork. Internal temperature should reach 145°F.
07 - Remove from oven, sprinkle with additional fresh dill, and serve immediately while hot.
