How to Pan-Sear a Whole Fish
A whole fish is the most forgiving way to cook seafood because the skin and bones act as a natural roasting rack. When you pan-sear, you are managing the transition between crispy exterior and flaky, opaque flesh.
Dry skin is the only secret.
Moisture is the enemy of a sear. If the skin is wet, the fish will steam rather than crisp, causing the skin to tear when you try to flip it.
- 12-inch cast iron or heavy-bottomed stainless steel skillet
- Fish spatula
- Paper towels
- Sharp knife
What goes in.
- 1whole snapper or branzino (about 1-1.5 lb), cleaned and scaled
- 2 tbspneutral oil, such as grapeseed or avocado
- 1 tspkosher salt
- 2 sprigsfresh thyme or rosemary
- 1 tbspcold butter
Don't force the flip
When you set the fish in the pan, leave it alone. If the fish sticks, it is not ready; the skin will naturally release from the pan once a proper crust has formed.
The method.
Prep the surface
Pat the fish inside and out until completely dry with paper towels. Use a sharp knife to score three diagonal lines across the thickest part of the flank on both sides.
Season
Rub the skin generously with salt, ensuring some gets into the scored slits. Do not add pepper yet, as it will burn at this heat.
Heat the pan
Place the skillet over medium-high heat. Add the oil. Once the oil shimmers and just begins to wisps of smoke appear, carefully lay the fish in the pan away from you.
Sear the first side
Let the fish cook undisturbed for 6 to 8 minutes. You will see the flesh turn opaque starting from the bottom up toward the spine.
Flip and finish
Using a fish spatula, slide under the thickest part and flip. Add the butter and herbs to the pan, spooning the foaming butter over the fish for the final 3-4 minutes until the internal temperature reaches 135°F.
Other turns to take.
Citrus Infusion
Tuck thin lemon wheels inside the cavity of the fish before searing to steam the interior with aromatics.
Spiced Crust
Mix a teaspoon of fennel seeds or coriander with your salt before rubbing the skin for a deeper, toasted profile.
When it doesn't go to plan.
Remove the fish from the refrigerator 15 minutes before cooking so the cold center doesn't drop your pan temperature.
If the pan gets too hot, move it slightly off the burner to regulate the heat without stopping the sear.
Use a stainless steel or cast iron pan; non-stick coatings often cannot handle the high heat required for a deep crust.

How do I know if the fish is cooked through?
The flesh should be opaque and pull away easily from the central bone when prodded with a fork.
Can I use olive oil?
Extra virgin olive oil has a low smoke point and will turn bitter. Stick to oils with high smoke points for searing.
