Detailed Directions and Instructions
Step 1: Prepare the Onion
Peel and finely dice the onion.
Step 2: Cook the Onion
Heat 2 tablespoons of olive oil and 2 tablespoons of the oil from the sardine tins in a saucepan over medium heat. Add the diced onion and a pinch of salt; cook for about 20 minutes until soft and just starting to color.
Step 3: Add Garlic and Chilli
Peel and finely chop the garlic; add it to the pan with the chilli flakes and cook for 2 minutes. Add the plum tomatoes, mashing them with a spoon. Simmer on low heat for 25 minutes.
Step 4: Preheat the Oven
Preheat the oven to 190°C.
Step 5: Make the White Sauce
Melt the butter in a medium saucepan over medium heat. Once foaming, add the flour, mix to a paste, and cook for 1 minute. Remove from heat and gradually pour in the milk in small increments, stirring continuously to ensure a smooth mixture before adding more.
Step 6: Thicken the White Sauce
Once all the milk is added, return the pan to heat, add the bay leaf, bring to a boil, then simmer for 3 minutes to thicken. Grate in 50g of Grana Padano, tear in all the mozzarella, and whisk to combine. Season with salt and black pepper to taste.
Step 7: Prepare Sardines and Olives
Drain the sardines. Squash, destone, and roughly chop the olives. Finely chop the parsley. Add the sardines and olives to the red sauce, mix, and simmer for another 2 minutes. Season with parsley, salt, and pepper to taste.
Step 8: Cook Lasagne Sheets
Bring a saucepan of salted water to a boil. Add the lasagne sheets one at a time and cook for 3 minutes until they become floppy. Store them on greaseproof paper while repeating with the rest.
Step 9: Assemble the Lasagne
Spoon a little of the red sauce into the base of a 30 x 20cm baking dish. Arrange a layer of lasagne sheets neatly on top, tearing sheets where necessary to fill gaps. Spoon over ⅕ of the remaining red sauce followed by ⅕ of the remaining white sauce, then more lasagne sheets. Continue layering until all mixtures are used.
Step 10: Final Layer and Bake
Mix the top layer so the red and white sauces combine, pushing them to the edges to ensure the lasagne sheets are fully covered. Grate over the remaining Grana Padano, then bake for 40 to 45 minutes.
Step 11: Serve
Let the lasagne stand for 5 to 10 minutes before slicing and serving.
