Step 1: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or lightly grease it with oil.
Step 2: Pat the salmon fillets completely dry with paper towels. Place them on the prepared baking sheet and drizzle with olive oil, then season evenly with salt and pepper.
Step 3: Bake the salmon in the preheated oven for 12-15 minutes, or until the internal temperature reaches 145°F and the fish flakes easily with a fork.
Step 4: While the salmon is baking, melt the butter in a small saucepan over medium-low heat. Add the minced garlic and cook for 1 minute until fragrant.
Step 5: Remove the saucepan from heat and whisk in the fresh lemon juice and lemon zest until the sauce is smooth and emulsified.
Step 6: Once the salmon is out of the oven, drizzle the lemon butter sauce generously over each fillet and garnish with fresh chopped parsley before serving.
