Halibut
Halibut's mild taste and firm texture suit searing or baking, allowing for delicate pairings.
Halibut is a large, flat white fish from the cold waters of the North Pacific and North Atlantic. Its flesh is mild, gently sweet and clean-tasting, with a buttery, oceanic note and firm, meaty flakes.
Cooks love halibut because it holds together beautifully in the pan or on the grill, yet stays delicate enough for lemon, herbs and light sauces. It is a perfect first fish for people who say they don't like fish.
Flavor profile
Aroma: mild, butter, oceanic
Good to know
Origin: Northern Hemisphere oceans
Forms: fillets, steaks
Season: Wild Pacific halibut is typically in season from spring to autumn; frozen fillets are available year-round.
Nutrition: A lean source of protein; halibut is fish, a common allergen.
Storage: Keep fresh halibut in the coldest part of the fridge, ideally on ice, and cook within 1–2 days. It freezes well for 3–6 months when tightly wrapped or vacuum sealed; thaw overnight in the fridge on a plate. Cooked halibut keeps 2–3 days chilled but dries out on reheating, so it is best flaked into salads or tacos. A strong fishy or ammonia smell, dull grey colour or slimy surface means it has spoiled.
How to use halibut
A Kind Sear
Sear it to develop a crust via the Maillard reaction. Keep moisture that lends natural sweetness.
Baked, Not Dried
Bake with lemon to keep moisture, leading to flaky tenderness.
The science of halibut
- Halibut is very lean, with little fat between its muscle fibres. That makes it mild and firm, but also quick to dry out once the proteins pass about 60°C (140°F) and squeeze out moisture.
- Fish muscle has short fibres held together by thin sheets of connective tissue that melt at fairly low temperatures. That is why halibut flakes into big, glossy pieces when it is cooked through.
- A golden crust comes from the Maillard reaction on a dry surface. Patting fillets dry and using a hot, oiled pan gives browning before the inside overcooks.
- Gentle methods like baking in parchment (en papillote) or poaching in wine trap steam around the fish, keeping it moist while acids like lemon and white wine sharpen its subtle sweetness.
How to choose halibut
Fresh halibut should look translucent and pearly white, feel firm and spring back when pressed, and smell like clean sea water, never fishy. Choose thick, centre-cut fillets for even cooking. Frozen-at-sea halibut is excellent and often fresher than fish sold as fresh far from the coast.
