Ingredients

• 1 white cabbage
• 90g butter
• 3 garlic cloves
• 200ml vegetable stock
• 500g prawns
• 1 tbsp olive oil
• 40g parmesan
• 1 unwaxed lemon

Method

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

1. Preheat the oven to 200 °C (180 °C fan). Cut the white cabbage into eight wedges, leaving the core on, and lay them in a large baking dish.
2. Melt the butter and stir in the crushed garlic, paprika, thyme, oregano, cayenne pepper and salt.
3. Brush the cabbage wedges with two-thirds of the Cajun butter, pour the vegetable stock into the dish and cover with foil. Cook the cabbage in the oven at 200 °C for 30 min.
4. Mix the prawns with the remaining Cajun butter and the olive oil. Remove the foil, scatter the prawns between the cabbage wedges and cook everything at 200 °C for another 10 min, until the prawns are pink.
5. Grate the parmesan over the top and let it melt in the oven at 200 °C for 3 min.
6. Chop the parsley, drizzle everything with lemon juice and serve the cabbage and prawns with the juices from the dish.

Good to know

In a cabbage boil, cabbage cooks in spiced butter until soft and sweet. Google counted it among the recipes with the biggest rise in searches in 2025, and Pinterest has named cabbage the vegetable for 2026. Prawns join in, as in a Louisiana seafood boil.

Swaps

Prawns → diced salmon (provides omega-3). Butter → ghee (contains milk). White cabbage → sweetheart cabbage (cooks in 20 min). Parmesan → leave it out.

Cooking tips

Leave the core on the wedges so they don't fall apart as they cook. Defrost frozen prawns first and pat them dry.

Storage

Leftovers keep for 1 day in the fridge; reheat them only briefly so the prawns don't turn tough.

Allergens

Contains crustaceans and milk; free from gluten, egg and nuts if the stock is gluten-free. In pregnancy, cook the prawns right through.
