Roasted Hispi Cabbage with White Bean Purée, Crispy Lardons and Mustard Dressing

# Roasted Hispi Cabbage with White Bean Purée, Crispy Lardons and Mustard Dressing

Hispi cabbage doesn't get nearly enough credit. It's sweet, tender, and when you roast it at high heat, the outer leaves char and crisp while the centre stays soft — it's one of those vegetables that genuinely surprises people.

This recipe pairs that caramelised cabbage with a creamy white bean purée, salty crispy lardons, and a sharp mustard dressing that ties the whole thing together. It works as a starter, a side, or a light main — and it comes together faster than you'd expect.

What is Hispi Cabbage, Exactly?

Hispi cabbage — also sold as sweetheart cabbage or pointed cabbage — is a variety of spring cabbage with a conical shape and tightly packed, tender leaves.

Compared to regular white or savoy cabbage, hispi is noticeably sweeter and more delicate. It doesn't have that aggressive sulphurous edge that puts some people off brassicas, which makes it a much easier sell at the dinner table.

It's widely available in UK supermarkets year-round, though it's at its best from spring through early autumn. You'll often find it cheaper than you'd expect — typically under £1 a head — which makes it an excellent base for a dish that feels a bit more restaurant-quality than your average weeknight dinner.

Why Roasting Changes Everything

Most people boil or steam cabbage, which is fine — but roasting is where things get interesting.

When cabbage hits a hot oven (or a searingly hot pan), the Maillard reaction kicks in. This is the same browning process responsible for the crust on a good steak or the golden edge of a roasted potato. The natural sugars in hispi caramelise, the outer leaves crisp up, and you get layers of flavour that boiled cabbage simply can't match.

The key is high heat and not crowding the pan. Halve the cabbage through the root — keeping the root intact holds the leaves together — then roast cut-side down in a very hot oven or finish in a cast iron pan. You want colour, not just warmth.

What Makes This Work Nutritionally

This dish is a genuinely well-balanced plate, and that's not by accident.

Hispi cabbage is low in calories but high in vitamin C, vitamin K, and folate. It also provides glucosinolates — compounds found in brassicas that have been studied for their potential role in supporting long-term health.

White beans (cannellini work well here) are the nutritional backbone of this recipe. They're rich in plant-based protein and fibre, which means the purée does far more than just add creaminess — it makes the dish genuinely satiating. A 100g serving of cooked cannellini beans provides around 8g of protein and 6g of fibre.

Lardons add fat and salt, which balances the mild bitterness of the cabbage and the earthiness of the beans. A small amount goes a long way — you're using them as a seasoning rather than a main ingredient.

The mustard dressing (Dijon, a little vinegar, olive oil) adds acidity and fat-soluble flavour compounds that help your body absorb the fat-soluble vitamins in the cabbage. It also just tastes brilliant.

What the Evidence Shows

There's solid research behind the ingredients here, particularly the beans and the brassicas.

A 2021 review published in Nutrients found that regular legume consumption is associated with improved satiety, better blood sugar management, and a reduced risk of cardiovascular disease. White beans specifically are among the highest-fibre legumes available, making them one of the more useful things you can add to your diet regularly — without any particular effort or cost.

On the brassica side, glucosinolates (the compounds in cabbage, broccoli, and their relatives) break down during digestion into biologically active forms including sulforaphane, which has been studied extensively in relation to inflammation and cellular health. The research is still developing, and it's worth not overstating it — but eating a variety of brassicas regularly is broadly supported as a good idea.

None of this makes this recipe a "superfood dish." It's just a flavourful plate of food built from ingredients that happen to be good for you — which is arguably the most sustainable approach to eating well.

The Recipe

Serves: 2 as a main, 4 as a starter or side

Time: 35 minutes

### Ingredients

For the cabbage: - 1 hispi cabbage, halved through the root - 2 tbsp olive oil - Salt and black pepper

For the white bean purée: - 1 x 400g tin cannellini beans, drained and rinsed - 1 small garlic clove - 2 tbsp olive oil - Juice of half a lemon - 3–4 tbsp warm water or vegetable stock - Salt to taste

For the lardons: - 100g smoked lardons (or smoked bacon, cut into small pieces)

For the mustard dressing: - 1 tsp Dijon mustard - 1 tbsp white wine vinegar - 3 tbsp extra virgin olive oil - Pinch of salt - Optional: 1 tsp honey

### Method

1. Roast the cabbage. Preheat your oven to 220°C fan. Brush the cut sides of the cabbage halves with olive oil and season well. Place cut-side down on a baking tray and roast for 20–25 minutes, until the cut face is deeply golden and the outer leaves are lightly charred. If you want more char on the leaves, finish under the grill for 2–3 minutes.

2. Make the white bean purée. While the cabbage roasts, blend the drained cannellini beans with the garlic, olive oil, lemon juice, and a pinch of salt. Add warm water or stock a tablespoon at a time until you reach a smooth, spoonable consistency — similar to hummus but slightly looser. Taste and adjust seasoning. Warm gently in a small pan before serving.

3. Crisp the lardons. Fry the lardons in a dry pan over medium-high heat until golden and crispy. Drain on kitchen paper.

4. Make the dressing. Whisk together the mustard, vinegar, olive oil, and salt. Add honey if you'd like a touch of sweetness to balance the sharpness.

5. Assemble. Spoon the warm bean purée onto plates. Place the roasted cabbage on top, cut-side up. Scatter over the crispy lardons and drizzle generously with the mustard dressing. Finish with a crack of black pepper and a few fresh herb leaves if you have them — tarragon, flat-leaf parsley, or chives all work well.

Variations and Swaps

This recipe is forgiving and adaptable.

Make it vegetarian: Skip the lardons and replace with toasted breadcrumbs fried in olive oil with a little smoked paprika. You get a similar crunch and a smoky hit without the meat.

Make it vegan: Same as above, and the dressing is already plant-based (just leave out the honey or swap for maple syrup).

No cannellini beans? Butter beans work beautifully and give an even creamier purée. Haricot beans are another good option.

Want more substance? Serve alongside a soft-boiled egg, or add a handful of cooked Puy lentils scattered across the plate for extra protein and texture.

Practical Takeaways

• Keep the root intact when halving the cabbage — it holds the leaves together during roasting and prevents the whole thing falling apart on the tray.
• Get the oven properly hot before the cabbage goes in. If the temperature isn't high enough, you'll steam rather than roast, and you'll lose the caramelisation that makes this dish.
• Make the purée ahead — it keeps well in the fridge for two to three days and reheats easily. It also works as a dip, a spread on toast, or a base for other roasted vegetables.
• Balance the dressing to your taste. If it's too sharp, add a small drizzle of honey. If it feels flat, a little more vinegar or a pinch of flaky salt usually fixes it.
• The lardons are best cooked fresh — they lose their crispness quickly, so fry them just before serving.
