Step-by-Step Guide to Making Mary Berry Spinach and Mushroom Lasagne

• Prepare the oven – Preheat the oven to 180°C (350°F).
• Cook the onions and garlic – Heat olive oil in a large pan and sauté the onions until soft. Add garlic and cook briefly.
• Add mushrooms – Stir in the sliced mushrooms and cook until they release moisture and begin to brown.
• Add spinach – Add fresh spinach and cook until wilted. Season with oregano, salt, and pepper.
• Prepare the white sauce – Melt butter in a saucepan. Stir in flour and cook for one minute.
• Add milk gradually – Whisk in the milk slowly, stirring constantly until the sauce thickens.
• Add cheese and seasoning – Stir in Parmesan cheese and a pinch of nutmeg.
• Start layering – Spread a little white sauce in the bottom of the baking dish.
• Add pasta sheets – Place a layer of lasagne sheets over the sauce.
• Add vegetable mixture – Spread some spinach and mushroom filling over the pasta.

What I Got Wrong (And How I Fixed It)

• Too much liquid from mushrooms – Cooking them longer removes excess moisture.

• Lasagne sheets were too dry – Ensuring enough sauce between layers solved this.
• Cutting too early – Allowing the lasagne to rest helped the layers hold together.

Healthier Version of Mary Berry’s Spinach and Mushroom Lasagne

To make a lighter version, replace part of the cheese with low-fat cheese while keeping the flavor balanced.

Reducing butter slightly in the white sauce can also lower fat content without affecting the texture too much.
