There’s a loose assumption in most kitchens that squash is squash — that the orange-fleshed gourds sitting together in October displays are essentially interchangeable. They’re not. They cook differently, taste differently, and the methods that make one excellent will make the other disappointing.
The two most commonly available in British shops and markets from October are butternut squash and crown prince pumpkin. Both are worth buying. Both need different handling.
Butternut squash
Butternut squash is the denser of the two. It has low moisture content relative to other squashes, a tight flesh that holds its shape under heat, and enough natural sugar to caramelise properly if the temperature is high enough and the pan isn’t overcrowded.
It wants 200°C or above. Cut into 3cm chunks, tossed with enough oil to coat — not just dampen — and spread in a single layer with actual space between the pieces. At 200°C for 30–35 minutes, the cut surfaces should be deeply golden, slightly catching at the edges, and the flesh should be completely soft. The outside is almost jammy; the inside is sweet and collapsing.
What it doesn’t respond well to: temperatures below 190°C (it steams rather than roasts and produces something watery and pale), and overcrowding on the tray (same problem). If you only have one tray and too much squash, use two pans or cook in batches. Crowded squash is not roasted squash.
What it pairs with: cumin, coriander, smoked paprika, chilli, sage, brown butter, tahini, feta, pomegranate. It has enough sugar to handle spice and enough body to stand up to strong flavours.
Crown prince pumpkin
Crown prince is the gunmetal blue-grey variety with a slightly flattened, irregular shape. Inside, the flesh is deep orange, denser than butternut in texture but with a higher natural sugar content that makes it easier to scorch.
It’s better at slightly lower heat — 190°C rather than 200°C — for slightly longer. The flesh is already intensely sweet before cooking, and the goal is to coax that out rather than drive it off through heat. Crown prince roasted at 200°C can become dry and leathery at the edges before the centre is cooked through. At 190°C for 35–40 minutes, it’s silky, intensely flavoured, and holds together better for salads or bowl dishes where you want intact pieces.
Cut it into larger wedges rather than small chunks — the surface area relative to volume is more forgiving, and it looks better on the plate. The skin is edible once roasted, though most people remove it.
What it pairs with: miso, honey, ginger, warm spices (cardamom, star anise in a braise), brown butter and sage, goat’s cheese. It’s sweet enough to sit alongside intensely savoury elements without getting lost.
Kabocha and delica
Both are increasingly available and worth knowing about. Kabocha (Japanese pumpkin) is smaller, darker green, and has a chestnut-like flavour that’s less sweet than butternut or crown prince. It’s excellent roasted at high heat (210°C) for shorter periods — 20–25 minutes in wedges — and is the best squash for frying in thin slices (it crisps rather than steaming).
Delica is a flat, dark green Italian pumpkin with an exceptionally sweet, dry flesh. It roasts well at 200°C in wedges and makes the best pumpkin soup of any variety — the flavour is clean and intense rather than watery.
The practical point
If you buy a butternut squash and a crown prince pumpkin and roast them together at the same temperature, one of them will be wrong. They’re not the same ingredient, even if they’re in the same family and sold side by side.
The solution isn’t complicated — adjust the temperature, check the size of the chunks, give them space on the tray. The technique is small. The difference it makes is significant.
Autumn produce rewards the cook who pays attention to which specific vegetable they have in front of them, not just which category it belongs to.
