Preheat the oven to 350 F (180 C), no convection or fan. Remove bones from the fish if any, remove skin if you prefer skinless. Lightly coat salmon with a few drops of oil. Salt and pepper. Slice garlic in 3-4 thick slices.
Heat up the pan over high heat, then turn the heat down to medium-low. Place the salmon fillets in the hot pan skin side down. Place garlic slices on top. Cook for 2 minutes on one side.
Turn the fish with a thin spatula and cook for another 2 minutes on the other side.
Turn the fish again with a spatula. Discard garlic slices. Place the pan into the oven. Cook for 4-5 minutes, or 10 if you like it really well cooked. Take out from the oven and let it rest for 4-5 minutes.
