Australian Soup Recipes: Classic Pumpkin Soup to Make

Australian pumpkin soup is a familiar home-style soup made with pumpkin, stock and often a little cream; it is served hot as a starter or a simple meal. This version roasts the pumpkin first for a deeper, sweeter flavour, then simmers it with leek and onion before blending. There is no single definitive Australian recipe, and pumpkin varieties and seasonings vary between households.

Ingredients

8 cups (1.35 kg) peeled, seeded pumpkin, cut into roughly 1½-inch (4 cm) pieces; Kent, Jap or butternut pumpkin all work
2 tablespoons (30 ml) olive oil, divided
1 medium yellow onion, about 1 cup (150 g) chopped
1 medium leek, about 1 cup (150 g) thinly sliced, white and pale-green parts only
3 garlic cloves, about 1 tablespoon (9 g) finely chopped
1 teaspoon (5 g) fine salt, plus more to taste
½ teaspoon (1 g) freshly ground black pepper
1 teaspoon (2 g) ground cumin
¼ teaspoon (0.5 g) ground nutmeg
5 cups (1.2 L) vegetable or chicken stock, preferably lower-sodium
1 cup (240 ml) heavy cream, plus a little extra for serving if desired
1 teaspoon (5 ml) lemon juice, or more to taste
¼ cup (30 g) pepitas, for serving (optional)
2 tablespoons (8 g) chopped flat-leaf parsley, for serving (optional)

Instructions

Heat the oven and prepare the pumpkin. Set a rack in the centre of the oven and preheat it to 425°F (220°C). If the pumpkin is whole, use a sturdy knife to halve it, scoop out the seeds and peel it before cutting the flesh into pieces. Cut the pieces to a similar size so they roast evenly. Put them on a large rimmed baking sheet, drizzle with 1 tablespoon (15 ml) of the olive oil, and toss to coat. Spread them out in one layer, with a little room between pieces, and season with a pinch of the measured salt and pepper.
Roast until tender and browned. Roast the pumpkin for about 35 minutes, turning the pieces once after roughly 20 minutes. It is ready when a fork slides through the thickest pieces easily and the edges have picked up some colour. If the pieces are crowded, use two baking sheets rather than piling them up; crowded pumpkin steams and will taste less roasted. The roasting time is a useful guide, but the size and variety of the pumpkin can affect it by several minutes.
Soften the aromatics. While the pumpkin roasts, warm the remaining 1 tablespoon (15 ml) olive oil in a large heavy pot or Dutch oven over medium heat. Add the onion and leek with a small pinch of salt. Cook for about 6 minutes, stirring occasionally, until soft and translucent but not browned. Stir in the garlic, cumin and nutmeg and cook for 1 to 2 minutes, just until fragrant. Keep the heat moderate; scorched garlic can make the finished soup taste bitter.
Add the pumpkin and stock. Tip the roasted pumpkin into the pot, scraping any browned bits from the baking sheet into the soup if they come away easily. Pour in the 5 cups (1.2 L) stock and add the remaining salt and pepper. Bring the liquid just to a boil, then lower the heat so it simmers gently for 12 minutes. Stir once or twice and check that the pumpkin is very soft. A gentle simmer is enough; a hard boil can make the stock evaporate quickly and splatter.
Blend until smooth. Take the pot off the heat. Use an immersion blender to puree the soup until it looks smooth, moving the blender around the pot and keeping its head submerged to limit splashes. If using a countertop blender, work in small batches, fill it no more than halfway, and vent the lid according to the blender’s instructions because hot liquid expands. Return the soup to the pot. If it is thicker than you like, stir in additional stock or water a little at a time.
Finish and season. Stir in the cream and lemon juice. Warm the soup over low heat for about 5 minutes, stirring, without letting it boil. Taste and adjust with more salt, pepper or lemon juice. The lemon should brighten the pumpkin rather than make the soup taste distinctly sour. Serve hot, topped with pepitas and parsley if using.

Tips

Choose a dense pumpkin. Kent, also called Jap pumpkin in Australia, is a good choice when available, with sweet flesh that blends smoothly. Butternut squash is a reliable substitute in many places and has a similar sweet, creamy texture. Kabocha works too, though its flavour is a little earthier and it may need a splash more stock after blending.
Wash the leek carefully. Dirt can lodge between its layers. Slice it first, swish the pieces in a bowl of cold water, then lift them out so the grit stays behind. Drain well before cooking; a very wet leek can make the aromatics sputter in hot oil.
Adjust thickness after blending. Pumpkin moisture varies, so avoid adding extra liquid before you know the texture. For a thicker bowl, simmer the blended soup uncovered for a few minutes; for a thinner one, add stock in small splashes. Taste again after either adjustment because added liquid can dilute the seasoning.
Keep the cream from splitting. Add it after blending and warm the soup gently rather than boiling it. For a dairy-free version, use unsweetened coconut milk or a plain oat cooking cream; coconut milk adds a noticeable coconut note, while oat cream is more neutral.

Serving Suggestions

Serve this soup in warmed bowls with crusty sourdough, a toasted cheese sandwich or buttered toast for dipping. For a more substantial lunch, add a crisp green salad with a sharp vinaigrette; its freshness balances the soup’s creamy sweetness. A small bowl of pepitas, chopped parsley and extra cream at the table lets everyone add their own toppings. If serving the soup as a starter, keep the portions modest and follow it with a savoury main dish rather than adding several rich toppings.

For a relaxed meal, set out bread and a simple topping board with toasted seeds, chopped herbs, cracked pepper and lemon wedges. The soup is filling enough to stand on its own, but a little texture makes each bowl more interesting. If the soup is being served to guests, warm the bowls with hot water, dry them, and ladle in the soup just before serving so it stays hot longer. Keep any toppings separate until serving so the seeds remain crisp.

Variations

Curried pumpkin soup: Add 1 to 2 teaspoons (2 to 4 g) mild curry powder with the garlic and cumin. Start with the smaller amount if you want the pumpkin to remain the main flavour. A spoonful of coconut milk in each bowl works well with the spices, although it shifts the soup away from the classic cream-finished version.

Apple and pumpkin: Add one peeled, cored apple, about 1 cup (150 g) chopped, to the pot with the leek. Its gentle tartness adds another layer of flavour. Choose a firm eating apple rather than a very sweet variety, and taste the soup before adding the lemon juice because the apple may already provide enough brightness.

More savoury and less creamy: Leave out the cream and use vegetable stock. Stir in a tablespoon (15 ml) of olive oil after blending for a rounded finish, or serve with a spoonful of plain yoghurt if dairy is suitable. The result will be lighter in texture and let the roasted pumpkin flavour stand out more clearly.

Roasted garlic: Roast a whole garlic bulb alongside the pumpkin, wrapped loosely in foil, until the cloves are soft, then squeeze them into the pot before blending. This gives the soup a mellow, sweet garlic flavour instead of the sharper note from fresh garlic. Because oven temperatures and bulb sizes differ, check that the cloves are completely tender before using.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours in a covered, shallow container. The soup keeps for 3 to 4 days in the refrigerator. For longer storage, freeze it in meal-sized airtight containers for up to 3 months for best quality, leaving a little headspace for expansion. Thaw frozen soup overnight in the refrigerator. Cream-based soup can separate slightly after freezing, but stirring while reheating, or briefly blending it again, usually brings the texture back together.

Reheat only the portion you plan to serve, on the stove over medium-low heat, stirring regularly until it is steaming throughout. USDA FSIS guidance is to reheat leftovers to 165°F (74°C); check the temperature with a food thermometer, especially when warming a large batch. Avoid a vigorous boil, which can cause cream to separate and make the soup spit. If it thickens in the refrigerator, loosen it with a little stock or water, then taste and adjust the seasoning.

Frequently Asked Questions

Can I make Australian pumpkin soup without roasting the pumpkin?

Yes. Peel and cut the pumpkin, then add it directly to the pot after the leek and spices have softened. Pour in the stock and simmer until the pumpkin is tender, usually about 20 to 25 minutes depending on the size of the pieces. The soup will still be good, but roasting develops browned edges and a deeper flavour, so the result will taste milder and less caramelised.

What pumpkin is best for this soup?

Choose a firm, sweet-fleshed pumpkin that feels heavy for its size and has no soft spots. Kent or Jap pumpkin is a common Australian choice; butternut squash is an easy substitute outside Australia, and kabocha also works. Avoid pumpkin sold mainly for carving if it is watery or bland. Because varieties hold different amounts of moisture, use the recipe’s stock amount as a starting point and adjust after blending.

Can I make it ahead?

Yes. Make the soup through the blending step, cool it promptly and refrigerate it, then stir in the cream when reheating for the freshest texture. It can also be made with the cream already added; reheat gently and stir well. Follow the storage timings above, and do not leave the pot at room temperature for an extended period while it cools.

How can I make the soup vegan?

Use vegetable stock and replace the cream with unsweetened coconut milk, plain oat cooking cream or another unsweetened plant-based cooking cream. Check that the chosen product is intended for savoury cooking. Coconut milk gives the soup a distinct flavour, while oat cream is generally more neutral. You can also omit cream entirely and blend thoroughly for a smooth, lighter soup.

Why is my pumpkin soup too thin or too thick?

Pumpkins differ in moisture, and the amount of liquid lost during simmering can vary. If the soup is too thin, simmer it uncovered until some liquid evaporates, stirring to prevent sticking. If it is too thick, add warm stock or water a little at a time. Make the adjustment before the final seasoning, then taste again because changing the liquid level changes how salty and bright the soup seems.

Can I use a regular blender for hot soup?

Yes, but blend carefully. Hot liquid can build pressure under a tightly sealed lid, so follow the blender maker’s directions, vent the lid if appropriate, and work in small batches filled no more than halfway. Hold a folded towel over the lid while blending if the appliance instructions allow it, and start on a low speed. An immersion blender is usually easier because the soup can remain in the pot.
