  2. Butter the bottom of a flat, fire-safe dish.

Assemble and bake

  1. Sprinkle grated onion, pepper, and salt over the bottom.

  2. Place the fish on top and brush it with the egg yolk.

  3. Sprinkle with more grated onion, pepper, salt, and chopped parsley.

  4. Pour lemon juice over the fish and dot with bits of butter.

  5. Bake in a moderate oven at 350°F (175°C) for 30 minutes.

Serve

  1. Serve in the baking dish, garnished with parsley and lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Halibut steak
Forms the main body of the dish, cooking gently to flaky, moist flesh.
Egg yolk
Brushed on the fish, it enriches the surface and helps it brown and set.
Butter
Adds fat and richness, carrying flavor and keeping the fish moist as it bakes.
Grated onion
Contributes savory aroma and moisture that perfumes the fish as it cooks.
Lemon juice
Adds acidity that brightens the rich butter and mild fish flavor.

The step that matters

Baking the fish. Halibut is lean and dries out quickly in heat. Baking it just until it flakes, while the butter and onion keep it moist, prevents a tough, dry texture.

Swap the onion
