For ultra-defined layers, bake this deep dish lasagne a day ahead. After chilling it will slice easily, and still hold its shape when reheated. Rich and cheesy, this is best served in small portions with a tomato, red onion and rocket salad, drizzled with sweet-sharp balsamic vinegar

Step by step
Get ahead
Best made the day before, cooled and chilled (or frozen in portions). See step 7 for reheating.
Preheat the oven to 200°C, fan 180°C, gas 6. Fully line a loose-based 20cm square cake tin with a double layer of foil and grease with a little butter. Cut 2 long strips of baking paper, 20cm wide, and lay them in the tin crossways, with the excess extending over the sides.
Melt 25g of the butter in your largest saucepan. Cook the leeks and garlic with a pinch of salt over a medium-low heat for 5 minutes until softened. Add the spinach (in batches if necessary), cover and leave to wilt for 5 minutes. Stir to combine, season with nutmeg and black pepper and tip into a colander over a large bowl to drain.
Melt the remaining 100g butter in a large pan. Add the flour and cook for 1-2 minutes, stirring. Remove from the heat and gradually add the milk. Cook on a medium heat, stirring continuously, until the sauce has thickened. Turn off the heat and whisk in two-thirds of the Parmesan, followed by the ricotta, until smooth. Season to taste and spoon out 2 ladlefuls of the sauce to reserve for the top of the lasagne. Stir the drained spinach and leek mixture into the sauce left in the pan.
Put the lasagne sheets in a heatproof dish, cover with boiling water from the kettle and leave to soften for 1 minute then lift out to a board. Cut the sheets to size so that they will fit neatly into the prepared tin.
Spread a thin layer of the spinach sauce (about one-eighth) in the base of the prepared tin. Scatter with a small handful of feta, followed by a layer of lasagne sheets. Repeat these three layers, seven more times, finishing with lasagne sheets. Spread over the reserved white sauce, then scatter with the remaining Parmesan and the pine nuts.
Sit the tin on an oven tray; bake for 40-45 minutes until golden brown and bubbling. Rest for 15 minutes and serve, or see our Get Ahead tip above.
To reheat, preheat the oven to 190°C, fan 170°C, gas 5. Push the lasagne out of the tin from the base and cut into 9 squares. Place the desired number of squares in a large ovenproof dish, cover with foil and bake for 35-40 minutes until piping hot. Uncover and bake for a further 5 minutes to crisp up the top. Any other squares can be frozen for another time, then defrosted before reheating.
*Use vegetarian cheese if required

After the initial sauce layer, add a layer of pasta sheets, ricotta mixture (or bechamel), sauce, and cheese. Then repeat the layers. Top the last layer of your lasagna with sauce and cheese. You can also alternate layers of sauce and ricotta cheese.
Adding egg to ricotta cheese helps to bind the cheese for lasagna so that it doesn't ooze out of the casserole when you cut it. Basically, the egg helps all the cheesy goodness stay intact. So what happens if you don't put eggs in your lasagna? It'll just be a bit runnier, but omitting the egg won't affect the taste.
For extra creamy ricotta, add in an extra egg, a handful of grated parmesan, and a quarter cup of shredded mozzarella. Eggs help prevent the ricotta from drying out and serve to bind the ricotta so it doesn't become runny. One or more eggs are recommended whether you add the other ingredients mentioned here or not.
Its mild flavor works really well with the mozzarella. Tomato Sauce & Paste: An important component in lasagna. Choosing your favorite tomato sauce will guarantee that you'll love this recipe. A good tomato paste helps to thicken but also adds a sweet and savory umami flavor.
Sugar: Two tablespoons of white sugar add subtle sweetness and enhance the flavor of the sauce. Spices and seasonings: This lasagna recipe is flavored with fresh parsley, dried basil leaves, salt, Italian seasoning, fennel seeds, and black pepper. Lasagna noodles: Use store-bought or homemade lasagna noodles.
The biggest offender, though, is watery, thin pasta sauce. A helpful technique can prevent this pitfall from sabotaging your lasagna: Reduce your sauce to thicken it before pouring it into the casserole. A thin sauce runs right off of cooked lasagna noodles, causing all the layers to slide off of each other, as well.
(Do notice that I put the noodles criss cross – perpendicular from the layer below – it helps it to hold together when you serve it). So, the noodles directly on the cheese means there won't be enough for a top layer of noodles.
Finish off your lasagne either with a layer of tomato-based sauce or with your white sauce – whichever you have left – and then grate over plenty of Parmigiano-Reggiano. A common extra topping is torn mozzarella, which makes a lovely, melted cheesy layer on top.
You will definitely want to cover your lasagna before cooking it. This keeps it from drying out, especially on top. At the end of the cook time, you'll broil it for a minute or two to get the cheese on top bubbly.
What is the difference between lasagna and lasagne al forno? Unlike Americanized lasagna, this authentic lasagne al forno recipe is made without ricotta cheese. Instead, this recipe used homemade lasagne noodles and a creamy béchamel sauce.
Start by spreading a layer of your tomato-based sauce (either a plain tomato sauce or your pre-made ragù) on the bottom of your dish. Next, add a single layer of pasta sheets. Then, add a layer of white sauce, followed by another single layer of pasta sheets.
Soak the lasagne sheets in a single layer in boiling water for 5 mins. (Although the packet says no pre-cook, I find soaking improves the texture.) Drain well.
