Chef's note

Brown butter provides a rich, savory depth that perfectly complements the fattiness of the salmon without overpowering it.

Method

8 steps · tap one to tick it off

Tips

  • Preheat the cast iron thoroughly. Cast iron heats unevenly at first. Give it several minutes over medium-high so the whole base is hot when the salmon goes in.

  • Let the pan cool before the butter. Cast iron holds a lot of heat. Give it a minute after the salmon comes out, or the butter burns before it browns.

  • Add the lemon juice off the heat. Brown butter foams up hard when lemon juice hits it. Take the pan off the heat first to avoid splatter.

Swaps

  • No kosher salt? Table salt, about half as much, since its fine grains pack more salt into each pinch.

  • No fresh flat-leaf parsley? Chives or dill, chopped the same way.

  • No lemon juice? White wine vinegar, about half as much.

Storage

  • Fridge: 3 to 4 days in a sealed container. Keep the butter sauce with the fish; it sets in the fridge and melts again.

  • Freezer: 2 to 3 months for best quality. The flesh comes back slightly drier and the skin soft.

  • Reheat: Covered in a 140°C oven with a splash of water, until steaming hot (75°C in the center).

Fridge and reheating follow Illinois Extension; freezer times are for quality and follow the University of Nebraska-Lincoln, as on what freezes and what does not.
