Preheat your oven to 200°C (392°F).
Wash the lemons thoroughly and zest one of them. Then, juice both lemons to get about 60 ml of lemon juice.
In a small bowl, combine the lemon zest, lemon juice, olive oil, minced garlic (if using), salt, and black pepper. Mix well to create the lemon pepper marinade.
Place the salmon fillets in a shallow dish or a resealable plastic bag and pour the marinade over them. Make sure the salmon is coated evenly. Allow it to marinate for about 15-30 minutes in the refrigerator. You can also marinate it longer for a more intense flavor.
While the salmon is marinating, prepare a baking sheet lined with parchment paper or lightly greased.
Transfer the marinated salmon fillets to the prepared baking sheet, skin side down.
Bake the salmon in the preheated oven for 12 minutes, or until it flakes easily with a fork. The exact cooking time may vary depending on the thickness of your salmon fillets, so keep an eye on them to avoid overcooking.
Once the salmon is cooked through, remove it from the oven and garnish with fresh parsley if desired.
Serve your lemon pepper salmon hot with your favorite side dishes, such as steamed vegetables, rice, or a fresh salad.Enjoy your delicious lemon pepper salmon!
