Norwegian Blomkålsuppe – Creamy Vegan Cauliflower Soup with Crispy Ham

What Is Blomkålsuppe?
Blomkålsuppe is the Norwegian name for cauliflower soup. It is a traditional home-style dish that combines cauliflower with broth, milk or cream and mild seasonings. Depending on the household, it may be completely smooth or contain small cauliflower florets. Its creamy texture and delicate flavour make it a popular choice for a warming everyday meal.

Cauliflower – A Member of the Brassica Family
Cauliflower belongs to the Brassica family, alongside broccoli, cabbage, kale and Brussels sprouts. Its edible white head consists of tightly packed immature flower buds. Cauliflower has a mild, slightly nutty flavour that becomes sweeter when cooked, making it suitable for roasting, steaming, soups and many other dishes.

Cauliflower and Vitamin C
Cauliflower is naturally a source of vitamin C, which contributes to normal immune function and helps protect cells from oxidative stress. It also contains dietary fibre and folate. Because vitamin C is sensitive to prolonged heating, gentle cooking and avoiding unnecessarily long boiling times can help preserve more of this nutrient.

Why Nutmeg Is So Important
Nutmeg has a warm, aromatic flavour that complements creamy vegetable dishes beautifully. It is frequently used in cauliflower, potato and other mild vegetable preparations across Northern and Central Europe. Freshly grated nutmeg has a particularly fragrant aroma, so even a small pinch can add noticeable depth without overpowering the cauliflower.

How a Roux Makes Soup Creamy
A roux is a mixture of fat and flour cooked briefly before liquid is added. As the flour's starch absorbs liquid and heats up, it thickens the soup and creates a smoother consistency. For a pale cauliflower soup, the roux should remain light in colour rather than becoming deeply browned. Whisking the liquid in gradually helps prevent lumps.

Oat Drink vs. Dairy Milk in Cooking
Unsweetened oat drink has a mild flavour that works well in creamy vegetable soups. It blends easily with cauliflower and contributes a gentle sweetness without dominating the dish. For savoury cooking, always choose an unsweetened, preferably unflavoured variety, as sweetened or vanilla-flavoured oat drinks can noticeably change the taste.

Why Soy Cream Works So Well
Soy cooking cream provides a smooth, creamy texture and generally has a relatively neutral flavour. It is a useful dairy-free alternative in soups, sauces and savoury dishes. Its protein and fat content varies between brands, so the final richness and thickness may differ slightly. Adding it towards the end of cooking helps maintain a smooth consistency.

White Pepper vs. Black Pepper
White and black pepper come from the same plant but are processed differently. White pepper is made from the inner seed after the outer fruit layer has been removed, giving it a different, often earthier flavour. It is commonly used in pale soups and sauces because it blends visually into the dish without leaving dark specks. Black pepper offers a more familiar aromatic sharpness and works equally well if preferred.

Why Crispy Toppings Make Creamy Soups Better
Creamy soups benefit from contrasting textures. Crispy vegan ham cubes introduce a savoury bite that balances the smooth cauliflower base, while spring onions add freshness and a delicate onion flavour. Adding the toppings immediately before serving preserves their texture and makes the dish more visually appealing.

Zero Waste – Don't Throw Away the Cauliflower Stem and Leaves!
The tender cauliflower stem and fresh leaves are edible and full of flavour. Peel away any particularly tough outer skin from the stem, chop the tender centre and cook it directly into the soup. The leaves can be finely sliced and added to vegetable dishes, roasted until lightly crisp or saved for homemade stock. Using more of the cauliflower is an easy way to reduce food waste while making the most of your ingredients.
