Step by step

Get ahead

Assemble a couple of hours before cooking.

Preheat the oven to 220°C, fan 200°C, gas 7. Divide the quartered sprouts between 2 large, deep roasting tins and drizzle 3 tablespoons of oil into each tin. Divide the thyme sprigs between the tins and season well, tossing everything together. Roast for 15-20 minutes or until golden and crispy. Remove from the oven and set aside, discarding the thyme. Turn the oven down to 200°C, fan 180°C, gas 6.
To make the sauce, first put the milk in a small saucepan. Stud the onion with the cloves and add it to the milk, along with the bay leaf. Gently bring to the boil over a low heat, then remove from the heat and leave to infuse for a few minutes before removing the bay leaf and onion.
Melt the butter in another saucepan and add the flour, plus some seasoning. Cook over a low heat for about 1 minute, stirring, to get rid of the raw floury taste, but avoid letting it brown. Add a ladle of the infused milk and stir to combine. Continue adding the milk a little at a time until you have a thick pouring sauce. Add the cheddar plus the mustards, to taste, and mix well. Season; remove from the heat.
Remove the lasagne sheets from their packaging and place in a large bowl. Cover with boiling water and leave to stand for 2 minutes. Drain well. Toss with 1 teaspoon of oil to prevent them sticking together.
To assemble the lasagne, put a third of the roasted sprouts in the base of an ovenproof dish, approximately 20 x 30cm, and spread out. Cover with a third of the cheese sauce. Layer half the pasta sheets on top, then add half of the remaining sprouts. Add another third of the sauce, then the rest of the lasagne sheets. Top with the remaining sauce, then the last of the sprouts. Top with the grated cheeses and a good amount of black pepper. Sit the dish on a baking tray and bake for 20 minutes, until the top is golden. Let it stand for 5-10 minutes before serving.
Tip You can use 100g Gruyère on top of the lasagne, but be aware that this is not strictly vegetarian as it’s made using rennet
