FAQ
Can I use frozen swordfish steaks?
Yes, but thaw completely and pat very dry before seasoning. Frozen fish releases more moisture which can prevent proper browning.
What if I don't have anchovies?
Omit them or substitute with a pinch of fish sauce or Worcestershire sauce for similar umami depth.
How long will leftovers keep?
Cooked swordfish keeps refrigerated for up to 2 days. Reheat gently in a low oven to avoid overcooking.
