1. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
2. In a small saucepan, melt the butter over medium heat. Add the minced garlic and sauté for about 2 minutes, until fragrant. Stir in the lemon juice and zest, then remove from heat.
3. Pat the salmon fillets dry with paper towels and season both sides with salt and pepper. Place them skin-side down on the prepared baking sheet.
4. Brush the salmon generously with the garlic butter mixture, making sure each fillet is well-coated.
5. Drizzle the olive oil over the salmon to help crisp the skin as it bakes.
6. Bake in the preheated oven for 12-15 minutes, or until the salmon is cooked through and flakes easily with a fork.
7. Remove from the oven and let rest for a couple of minutes. Garnish with fresh parsley before serving.

One of my favorite tricks, learned from years of watching my abuela, is to taste as you go. If you feel the garlic butter needs a touch more citrus, trust your instincts and add a bit more lemon juice. Cooking, after all, is as much about intuition as it is about following recipes.
