Preheat the Pan: Start with a pan on a medium or high heat. You want it hot but not ripping hot.
Season the Salmon: Season your salmon with salt. In restaurants, you might score the skin, but at home, you can skip this step.
Add Olive Oil to the Pan: Add a decent amount of olive oil to the pan.
Cook the Salmon: Once the oil is hot, add your salmon. Season the top and use something like a protein press to apply some gentle pressure. If you don't have a protein press, you can simply use another fry pan.
Lower the Heat: Temperature control is super important. Turn the heat right down low now. You don't want the fish to cook too rapidly.
Check for Doneness: Cook almost all the way through before flipping. You can see on the side how far up the piece of flesh it's cooked. After about 5 minutes, check if it's almost fully cooked through.
Flip the Salmon: Give it a flip to finish cooking. You should achieve glass-like skin and flesh that's still lovely and pink.
