How to Prepare Jamie Oliver Fish Lasagne – Simple Steps

Step 1: Prepare the Fish Carefully

Cut fish into medium-sized chunks and pat dry.

Season lightly with salt and pepper.

Avoid pre-cooking fully, as the fish will finish cooking in the oven.

Step 2: Make the Béchamel Sauce Smoothly

Melt butter in a saucepan over medium heat.

Stir in flour and cook for 1–2 minutes to form a roux.

Gradually add warm milk while whisking continuously.

Simmer until thick and smooth.

Season with salt and a pinch of nutmeg.

The sauce should coat the back of a spoon.

Step 3: Build the Base Layer

In a pan, heat olive oil and sauté the onion until soft.

Add garlic and cook briefly.

If using passata, simmer for 5–7 minutes to reduce slightly.

This prevents watery layers.

Step 4: Assemble the Layers Properly

Preheat oven to 180°C.

Spread a thin layer of sauce at the bottom of the dish.

Add lasagne sheets, then fish pieces, a spoonful of béchamel, and some tomato or herb mixture.

Repeat layers, finishing with béchamel and grated cheese on top.

Ensure pasta sheets are fully covered with sauce.

Step 5: Bake Until Golden

Bake for 35–40 minutes until pasta is tender, and the top is golden.

If browning too quickly, cover loosely with foil.

Step 6: Rest Before Serving

Allow lasagne to rest for 10–15 minutes before slicing.

Resting helps the layers set and improves presentation.
