Prepare: Preheat your oven to 450°F and line your baking sheet with your chosen non-stick material. Portion the salmon into four equal pieces and place them on the sheet, skin-side down.
Marinade Creation: In your small bowl, mix the parsley, garlic, olive oil, lemon juice, Dijon mustard, salt, and pepper until well combined.
Application: Evenly distribute the marinade across each salmon piece, ensuring both the top and sides are well-coated. Crown each piece with a lemon slice for that extra zest.
Baking: Place the salmon in the oven, baking for 12-15 minutes. You're aiming for a perfectly cooked interior that's just flaky enough to melt in your mouth.
Serve: Once baked to perfection, present your salmon with pride, knowing each bite offers a burst of flavors, perfectly balanced and utterly satisfying.
