Instruction to Make Mary Berry Vegetarian Lasagne

To make Mary Berry’s vegetarian lasagne, follow these steps:

Step 1: Preheat the oven and prepare the baking dish

Preheat the oven to 190C (fan 170C/375F/gas 5). Grease a baking dish measuring about 25cm x 20cm (10cm x 8in) and 5cm (2in) deep.

Step 2: Make the mushroom sauce

Heat the oil in a nonstick sauté pan, add the onion, and cook over medium heat for about 5 minutes or until just beginning to brown. Add the mushrooms and garlic, stir, then cook for about 5 minutes. Sprinkle in the flour and stir well.

Add the tomatoes, sugar salt, and pepper. Bring to a boil, then reduce the heat and simmer, uncovered, for about 15 minutes or until the sauce has reduced and thickened.

Stir in the shredded basil and balsamic vinegar. Check the seasoning and adjust if needed.

Step 3: Make the white sauce

Melt the butter in a saucepan, add the flour, and whisk over the heat for a minute. Gradually blend in the hot milk and whisk until bubbling and smooth. Season with salt, pepper and nutmeg.

Step 4: Assemble the lasagne

Spoon a third of the mushroom sauce over the bottom of the dish.

Scatter a third of the spinach over the mushroom sauce, using your fingers.

Spread a third of the white sauce over the spinach, then sprinkle with a third of the cheese.

Cover with a layer of lasagne sheets, not overlapping them. The dish will probably take 3 sheets, but you may have to break them to fit.

Repeat the layers of mushroom sauce, spinach, white sauce, cheese, and lasagne sheets twice more, finishing with cheese on top.

Step 5: Bake in the oven

Bake in the preheated oven for about 30 minutes or until golden brown and bubbling.

Step 6: Enjoy!

Let the lasagne rest for about 10 minutes before serving. Cut into slices and serve with a green salad or some crusty bread. Enjoy your Mary Berry vegetarian lasagne!
