Directions

First of all: Make the Fish Ragu Sauce

To make this exquisite and delicate Fish Lasagna recipe, first you have to make the main condiment which, together with the bechamel, will fill the lasagna layers: the fish ragu. This sauce is based on a mixture of crustaceans, molluscs, fish fillets and tomato passata. You can prepare the fish sauce even 1 or 2 days before and keep it in the refrigerator.

We summarize below the basic steps to make the fish ragu. For more informations and the detailed recipe see our step by step Fish Ragu Recipe.

fish lasagna step 1

Step 1) Clean the fish well and prepare a fish stock with the scraps, shells and claws, about a liter of water, a carrot, a piece of celery and a shallot. Boil all together for at least 40 minutes. This stock will be useful both for cooking the fish sauce and for preparing the bechamel (Step 4 – 5). If you use fish that is already cleaned and therefore have no waste, make with a vegetable stock; obviously the flavor will be less intense.

Step 2) – Make a soffritto with oil, garlic, onion and chopped parsley. Add the molluscs (squid and cuttlefish) cleaned and cut into small pieces and cook for about 5 minutes. Then blend with the white wine and add the tomato passata. Cook for about 40 minutes adding a little fish stock when necessary.

Step 3) – Now add the shellfish (shrimps and scampi) and the sea bass fillets, always cleaned and cut into pieces. Keep some shrimp whole. Cook for about 15 minutes, stirring well. For a successful fish ragu, cooking times are very important. Each type of fish has a different cooking time and you have to add it to the fish ragu based on that. Now the fish ragu is ready, keep it aside.

Prepare Fish Lasagna

Now that you have all the main preparations, we can start assembling the layers of your fish lasagna.

If you are using fresh pasta lasagna made with our recipe, DO NOT FORGET to dip them 1 minute in boiling salted water and let cool and dry on kitchen towels before using them for your lasagna recipe.

If you are using the lasagna noodles that we have recommended in the ingredients, you do NOT NEED TO COOK them. They will cook in the oven thanks to the liquids of the fish ragu and bechamel.

Step 6) – Spread on the bottom of a baking dish two tablespoons of bechamel. Then put a lasagna noodle over it, trying to cover the entire bottom of the pan. If one lasagna is not enough for you, use another one, whole or in half, depending on the size of the lasagna.

Step 8) – Repeat these steps for about five layers (lasagna – fish ragu – bèchamel ), in any case up to fill your baking dish. To the last layer, add a little more sauce and béchamel to form, during cooking, a crispy crust on the surface of the lasagna.

Step 9) – Bake in a preheated oven at 180 ° C (350 F) for about 30 minutes. For the first 10 minutes it is better keep the fish lasagna covered with a sheet of aluminum foil so that the sauce and the pieces of fish on the surface do not dry out too much. Before serving, let the fish lasagna rest for about 10 minutes out of the oven. Serve with a little fresh chopped parsley or ground black pepper according to taste.

Storage

Fish lasagna can be kept in the fridge covered with cling film for maximum of 1-2 days. You can even freeze fish lasagna, both raw and cooked.
