Step-by-Step Guide to Making Mary Berry’s Vegetarian Lasagne

Step 1: Prepare the Vegetables

Heat olive oil in a large pan. Add the chopped onion and garlic, cooking for 3–4 minutes until soft and fragrant. Add bell pepper, zucchini, and mushrooms. Sauté until the vegetables start to soften and release moisture.

Step 2: Make the Tomato Sauce

Stir in the chopped tomatoes, tomato purée, oregano, basil, salt, and pepper. Simmer for 10–12 minutes until thickened slightly. Taste and adjust seasoning. Set aside while preparing the white sauce.

Step 3: Prepare the Béchamel Sauce

Melt butter in a medium saucepan over low heat. Add flour and stir continuously for about 1 minute. Gradually whisk in milk, a little at a time, until smooth and creamy. Simmer gently until the sauce thickens. Stir in half of the Parmesan cheese and season with salt and pepper.

Step 4: Assemble the Lasagne

Preheat the oven to 190°C (375°F). In a baking dish, start with a thin layer of tomato-vegetable sauce, followed by lasagne sheets. Add a layer of béchamel sauce. Repeat these layers until all ingredients are used, finishing with a layer of béchamel on top.

Step 5: Add the Cheese Topping

Arrange mozzarella slices over the final layer and sprinkle with the remaining Parmesan cheese.

Step 6: Bake the Lasagne

Bake in the preheated oven for 30–35 minutes or until the top is golden brown and bubbling. Allow it to rest for 5 minutes before serving for easier slicing.

What I Got Wrong (And How I Fixed It)

• Used too much sauce: Made layers soggy—use just enough to coat each layer lightly.
• Didn’t pre-cook vegetables: Some remained watery—sauté first to remove excess moisture.
• Under-seasoned béchamel: Added a pinch more salt and nutmeg for flavor.
• Overbaked cheese topping: Covered loosely with foil during the final 10 minutes to prevent burning.

Healthier Version of Mary Berry Vegetarian Lasagne

For a lighter option, use skimmed milk for the béchamel, reduce the cheese quantity, and replace butter with olive oil. Add extra vegetables such as spinach, eggplant, or carrots for more fiber. You can also use whole-wheat lasagne sheets for added nutrition.

FAQs

How do I stop vegetarian lasagne from being watery?

To prevent a watery lasagne, cook the vegetables until all moisture has evaporated before layering. Avoid adding too much sauce, and let the lasagne rest for 5–10 minutes after baking. This allows it to set and hold its shape when sliced.

Do I need to pre-cook the lasagne sheets for vegetarian lasagne?

If using fresh lasagne sheets, there’s no need to pre-cook them. For dried pasta sheets, check the package instructions—most modern brands soften perfectly while baking, as long as there’s enough sauce and moisture in the dish.

How can I make the top of my lasagne golden and crispy?

For a perfectly golden top, sprinkle grated Parmesan or mozzarella over the final layer and bake uncovered for the last 10 minutes. You can also place the dish under the grill for 2–3 minutes for extra browning.

Can I prepare Mary Berry Vegetarian Lasagne ahead of time?

Yes, assemble the lasagne up to a day in advance, cover it tightly, and store it in the refrigerator. When ready to serve, bake it straight from the fridge at 190°C (375°F) for an extra 5–10 minutes until piping hot and bubbling.
