Ingredients for the béchamel sauce

  • Butter — 50 g

  • Plain (all-purpose) flour — 50 g

  • Milk — 4 cups

  • Ground nutmeg — 1/2 teaspoon

  • Salt and ground black pepper — to taste

Lasagna preparation steps

Step 1: Preparing the onion and garlic

Finely dice the onion. Heat the olive oil in a large skillet.

Add the chopped onion and sauté for a few minutes until it becomes golden and softened.

Crush the garlic cloves (or use a garlic press) to make a purée. Add the garlic purée to the pan and sauté briefly until fragrant.

Step 2: Adding the ground meat and spices

Add the ground beef to the pan and sauté over medium heat until the meat changes color and any raw smell disappears.

Then season with salt, black pepper and dried thyme to release the aroma of the spices.

Step 3: Preparing and adding the tomatoes

Add the tomato paste to the meat mixture and fry a few minutes to remove its raw edge.

At this stage, peel and finely chop the fresh tomatoes (or use canned chopped tomatoes) and add them to the pan.

Alternatively, blend the tomatoes in a blender and add the purée to the skillet.

Sauté the tomatoes briefly until their color deepens.

Step 4: Preparing and adding the bell pepper

Core and wash the bell pepper, then dice it finely.

Add the diced bell pepper to the meat mixture and stir through until combined.

Step 5: Preparing and adding the mushrooms

After washing, pat the mushrooms dry. Slice them and add them to the pan.

Turn the heat up a little so the mushrooms release liquid and start to brown slightly.

Cover the pan and let the mixture cook gently for 15–20 minutes so flavours meld.

For the best taste, allow the sauce to simmer slowly so the flavours develop fully.

Step 6: Making the béchamel sauce

Melt the butter in a saucepan over low heat. Add the flour and stir for about 2 minutes to remove the raw flour taste.

Gradually pour in the milk while whisking continuously so that no lumps form. Continue cooking the sauce over low heat until it thickens.

Season with salt, pepper and a pinch of nutmeg and stir.

The béchamel should not be overly thin; it should be creamy and thick enough to give the lasagna layers a luxurious texture.

Step 7: Preparing the lasagna sheets and the oven

If your lasagna sheets require pre-boiling, cook them briefly in boiling water until slightly soft, then rinse with cold water. Lay them on a towel to drain.

Preheat the oven to 180°C (356°F).

Step 8: Layering the lasagna

Spread a thin layer of béchamel over the bottom of the lasagna dish. Place a layer of lasagna sheets over the sauce.

Spoon a little béchamel over the sheets, and sprinkle a little grated Parmesan and shredded mozzarella on top of the béchamel.

Repeat these layers until you have used up the ingredients. Finish with a generous final layer of béchamel and lots of grated cheese on top.

Fresh mozzarella and freshly grated Parmesan add distinctive flavour and texture to the layers.

Step 9: Baking the lasagna

Bake the assembled lasagna for 25–30 minutes, until the layers are cooked through and the top is golden.

If you wish, finish under the grill (broiler) for a few minutes to achieve a crisp, browned top.

Allow the lasagna to rest for 10 minutes after baking; this helps the layers set and makes for neater slices.
