Fillets of Cod a LA Normande

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Place the fillets of cod in a baking dish.

Bake and serve

  1. Melt butter and mix with lemon juice, salt, and pepper.

  2. Pour the butter mixture over the cod fillets.

  3. Bake for 20 minutes or until the fish is cooked through.

  4. Garnish with chopped parsley before serving.

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

What each ingredient does

Fillets of cod
Forms the main body of the dish, flaking into tender pieces when cooked through.
Butter
Adds richness and moisture, helping keep the delicate fish from drying out in the oven.
Lemon juice
Adds acidity that brightens the buttery sauce and balances its richness.

The step that matters

Bake until the fish is cooked through. Cod is lean and cooks quickly, so overbaking dries and toughens the flesh. Check that it flakes easily with a fork at the stated time and stop as soon as it is opaque throughout.
