Mary Berry Vegetarian Lasagne in the Thermomix

How about a hearty, vegetable lasagna this weekend?

Arghhh that means countless hours in the kitchen, half a dozen pans to wash up and a big mess everywhere, doesn’t it? Not with a little help of Momo the Thermomix.

15 minutes active time … and NO washing up apart from the Thermomix bowl (in the dishwasher) and the lasagna dish.

Like the rest of the nation, we love a bit of Mary Berry cakes – I mean how could you not?

But it is not very often I cook some of her other recipes – that is about to change, after making this vegetable lasagne.

As much as we love the traditional, beef lasagna, we are also trying to cut down on our meat intake at the moment so this recipe sounded right up our street!

Active time: 15 minutes – Total time: 1h10


Bechamel/cheese sauce

  • 750ml milk
  • 60g salted butter
  • 90g plain flour
  • Salt & pepper to taste
  • 200g cheddar cheese

Vegetable filling

  • 1 onions
  • 2 garlic cloves
  • 2 tbsp olive oil
  • 500g button mushrooms
  • 2 courgettes, sliced
  • 2 tbsp plain flour
  • 1 bag fresh baby spinach
  • 400g chopped tomatoes
  • 1 tsp sugar

  • Salt & pepper to taste

  • 1 tbsp shredded fresh basil

  • salt and freshly ground black pepper


  • About 8 sheets no-precooking-required dried lasagne

Let’s go…

  1. First, add 200g cheddar cheese, roughly chopped, to the mixing bowl. Mix for 5 seconds / speed 5. Set aside. No need to rinse the bowl.
  2. Then make a bechamel/cheese sauce. Add 750g milk, 60g butter, 90g plain flour, salt & pepper to taste to the mixing bowl. Cook for 8 minutes / 90C / speed 4. 
  3. Add the reserved cheese and mix for a further 30 seconds / speed 2. Set Aside.
  4. In the meantime, slice 2 courgettes, wash the button mushrooms, peel and halve one onion and peel 2 garlic cloves.
  5. Wash the bowl.
  6. Add one onion, halved and 2 garlic cloves to the mixing bowl. Chop for 5 seconds / speed 5.
  7. Add 2tbsp olive oil and cook for 3 minutes / 100C / Speed low.
  8. Add 500g button mushrooms, whole, 2 courgettes, sliced and 2tbsp plain flour. Cook for 5 minutes / 100C / Reverse speed low.
  9. Add the baby leaf spinach, 400g chopped tomatoes, 1 tsp sugar and salt & pepper to taste. Cook for 15 minutes / 100C / Reverse speed low without measuring cup.
  10. In the meantime, preheat the oven to 180C and grease a baking dish measuring about 25cm x 20cm and 5cm deep.
  11. Stir the shredded basil into the vegetable sauce.
  12. Spread a third of the sauce over the bottom of the dish. Spread a third of the bechamel/cheese sauce over the vegetables.
  13. 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.
  14. Repeat the layers of vegetable sauce, cheese sauce, and lasagne sheets, then repeat the layers once more, finishing with the cheese sauce. Bake for about 30 minutes or until golden brown.

Delicious. Bon appetit x
