We just can’t get enough of this rich, creamy, cheesy classic. Comforting and delicious, this BISH BASH BOSH! recipe is one of our absolute favourites. You can even make the ragu and béchamel the day before, making it super easy to pop together when you want it. Yum!

Check out the recipe below.


2 onions
100g sun-dried tomatoes, plus 2 tbsp
oil from the jar
3 carrots
3 celery sticks
1 sprig fresh rosemary, plus more
for garnish
2 sprigs fresh thyme
4 garlic cloves
700g chestnut mushrooms
300ml red wine
1 tbsp tomato purée
1 tbsp red miso paste
1 tsp balsamic vinegar
½ tsp dried oregano
2 tsp soy sauce
2 x 400g tins chopped plum tomatoes
800ml water
500g dried lasagne sheets
salt and black pepper
salad leaves, to serve


125ml olive oil
125g flour
1.25 litres unsweetened plant-based milk
1½ tbsp nutritional yeast


Food processor | 2 large saucepans, one on a medium heat | Fine grater or Microplane | 25 x 30cm lasagne dish | Foil

Prepare the veg

Peel and quarter the onions and blitz them in the food processor until finely chopped | Add the sun-dried tomato oil to the large pan on the heat and sauté the onions, stirring, for 5–6 minutes |

Meanwhile, peel the carrots and pulse them in the food processor with the celery until minced | Remove the leaves from the rosemary and thyme and finely chop | Peel and grate the garlic and add it to the pan | Stir for 1 minute | Add the carrot, celery, rosemary and thyme, reduce the heat slightly and sauté, stirring occasionally, for 12–15 minutes

Meanwhile, thinly slice the sun-dried tomatoes | Pulse the mushrooms in the food processor until finely minced | Add to the pan along with the sun-dried tomatoes | Stir, increase the heat slightly and sauté, stirring, for 8–10 minutes

Pour in the wine, increase the heat and stir constantly for 5–6 minutes, until nearly all the liquid has evaporated | Add the tomato purée, miso paste, balsamic vinegar, oregano and soy sauce and stir for 1 minute | Add the chopped tomatoes and water | Lower the heat to medium and simmer for 30 minutes | Taste and season

While it is simmering, make the béchamel

Put the second pan over a medium heat and add the olive oil | Add the flour and stir for 3–5 minutes | Gradually add the milk, stirring constantly | Add the nutritional yeast and stir until smooth | Bring to the boil then lower the heat and simmer until the béchamel thickens to the consistency of custard | Taste and season | Preheat the oven to 180°C

Now, layer up your lasagne

Spread a quarter of the ragu into the lasagne dish | Spoon over a quarter of the béchamel | Cover with lasagne sheets, breaking them if necessary to make a complete layer with no gaps | Repeat three times, reserving some béchamel to cover the top completely | Garnish with a few rosemary leaves | Cover with foil and put on the lowest shelf of the oven | Bake for 50 minutes | Remove the foil and bake for a further 15 minutes | Leave to stand for 10 minutes before serving with the salad leaves | The leftovers will taste amazing the next day – simply bring back to piping hot in the oven or microwave

We can’t wait until dinner time. Will you be giving this recipe a go?
