The mushroom version is especially loved. Mushrooms give that deep, savory flavor usually missing in meat-free dishes.
I always cook them until the liquid has completely evaporated, which keeps the lasagne rich instead of watery.
Ingredients
The ingredients are the most important part of these dishes. If the ingredients are proper and delicious, the meal turns out great.
In my opinion, the number of people you’re cooking for is also crucial. For example, I’m cooking for four people, so the ingredients are measured accordingly.

How to Make Mary Berry Vegetable
Step 1 Soften the Lasagne Sheets
I soak the lasagne sheets in hot water for about 10–15 minutes, then drain well. This helps them cook evenly later.
Step 2 Cook the Onion
I heat the olive oil in a large frying pan and cook the onion over medium heat until soft and lightly golden.
Step 3 Add Mushrooms and Garlic
I add the mushrooms and garlic, cooking until all the moisture has cooked off. This step really matters for texture.
Step 4 Build the Tomato Sauce
Step 4, I stir in the flour, then add chopped tomatoes, thyme, balsamic vinegar, tomato paste, and spinach. I cook until bubbling and thick.
Step 5 Make the Cheese Sauce
I melt butter in a saucepan, stir in flour, then slowly whisk in hot milk. Once thick, I add mustard and most of the cheese, seasoning gently.
Step 6: Assemble the Lasagne
I layer vegetable sauce, cheese sauce, and lasagne sheets in the dish. I repeat the layers and finish with cheese sauce and grated cheese.
Step 7: Bake
I bake at 200°C (180°C fan) for 35–40 minutes until golden and bubbling. I let it rest before slicing.
Baking Instructions
I always bake it uncovered so the top browns nicely. If it colors too quickly, I loosely cover it with foil for the last few minutes.
Mary Berry Vegetable Lasagne With Mushrooms
This mushroom-heavy version is rich and satisfying. Even meat-lovers usually don’t notice the absence of meat, which always makes me smile.
Mary Berry Vegetable Lasagne With Spinach
Spinach adds freshness and balances the richness of the cheese sauce. I stir it in right at the end so it keeps its color.
Mary Berry Vegetable Lasagne With Aubergine
If I use aubergine, I roast it first. Raw aubergine releases too much liquid and can make the lasagne soggy.
Mary Berry Stress-Free Vegetable Lasagne Version
For a stress-free option, I assemble everything earlier in the day and refrigerate it. When dinner time comes, it just goes straight into the oven.
Can You Use Dried Lasagne Sheets in Mary Berry Vegetable Lasagne?
Yes, dried sheets work perfectly. I soak them briefly in hot water first, which helps them soften evenly during baking.
How to Stop Mary Berry’s Vegetable Lasagne From Being Watery
I always cook vegetables until dry, avoid using too much sauce, and let the lasagne rest before cutting. These three things fix most issues.
Make-Ahead Tips
You can assemble it up to 24 hours ahead and keep it chilled. Just allow a little extra baking time straight from the fridge.
Freezing
I freeze it fully cooled and tightly wrapped. It keeps well for up to two months without losing texture.
How to Reheat Mary Berry Vegetable Lasagne
I reheat it in the oven at 180°C until hot all the way through. The microwave works for single portions, but the oven keeps it nicer.
Health Benefits
- Good source of plant-based protein

Nutritional Value
Each serving gives a good balance of carbohydrates, fats, and protein, making it filling without feeling too heavy. I always feel satisfied after a portion.
Vegetarian Substitutes
You can use plant-based milk, vegan cheese, or add lentils for extra protein. I’ve tried lentils myself, and they work really well.
Serve
I usually serve it with a simple green salad or some garlic bread. Nothing fancy, just easy sides.
Family-Friendly
This is a great family dish because the vegetables melt into the sauce. Even picky eaters tend to enjoy it.
Common Mistakes
Using watery vegetables, under-seasoning the sauce, and slicing too soon are the most common mistakes I see.
Expert Tips
Season each layer lightly and always let it rest before serving. Small details make a big difference.
