Method

You’ll need: oven · saucepan · baking dish · chopping board · knife · sieve

1. Remove the outer leaves from the cauliflower and pre-cook it whole in boiling salted water for 8 minutes. Drain well.
2. Put the cauliflower into a baking dish, brush with melted butter, season with salt and thyme and bake in a preheated oven at 200 °C (180 °C fan) for 25 minutes.
3. Halve the Brussels sprouts, toss with the olive oil and salt and spread them around the cauliflower. Bake everything for another 10 minutes.
4. Finely chop the walnuts and mix with the grated parmesan, crushed garlic and grated lemon zest. Press the mixture onto the cauliflower and bake for 10 minutes, until the crust is golden brown.
5. Stir the soured cream with lemon juice, salt and pepper.
6. Cut the cauliflower into thick pieces at the table and serve with the Brussels sprouts and soured cream dip.

Good to know

A whole cauliflower with a golden crust is carved at the table like a roast. That way the vegetarian festive meal gets its big moment too.

Swaps

Parmesan → Alpine cheese (milder). Walnuts → almonds or hazelnuts. Soured cream → Greek yoghurt. Brussels sprouts → green beans.

Cooking tips

Pre-cooking in salted water makes sure the cauliflower is soft inside before the crust burns. A knife should go in easily before the crust step.

Storage

Leftovers keep for 2 days in the fridge and can be reheated in the oven at 180 °C.

Allergens

Contains milk and walnuts (tree nuts), gluten-free; parmesan is made with animal rennet, so for a strictly vegetarian version, choose hard cheese made with microbial rennet. Suitable for children and in pregnancy.
