Preheat the oven to 375°F. Line a baking sheet with aluminum foil, and optionally, place parchment paper on the foil.

Place the salmon on the prepared baking sheet.

Drizzle olive oil over the salmon. Zest one lemon and sprinkle the zest over the salmon along with salt and black pepper.

Slice the zested lemon and place the slices on top of the salmon.

Juice the second lemon and pour the juice evenly over the salmon.

Fold the foil over the salmon, sealing it to form a packet, leaving space inside for air to circulate.

Bake in the preheated oven for 18-21 minutes, depending on the thickness of the salmon.

Open the foil, switch the oven to broil, and broil the salmon for 3 minutes until slightly golden and fully cooked.

Remove from the oven and let it rest for a few minutes before serving. Serve with additional lemon slices if desired.
