A lower-calorie way to make Pumpkin Soup
Roast Pumpkin Soup Without Cream—Blend the Browned Flesh, Not Extra Fat
Roasting pumpkin cut-side down concentrates sweetness and gives a silky orange soup around 235 calories with yoghurt and pepitas.
Pumpkin soup tastes thin when pumpkin is boiled in too much stock, not because cream is absent. Roasting the cut face against a hot tray drives off water and creates brown flavour. That dense flesh needs less broth, so the blender can produce a creamy spoon trail on its own.
What changes—and what stays
From conventional 350–500 kcal with cream and butter to 235 calories
Roast 1.5kg pumpkin cut-side down with 1 teaspoon oil, then add stock only until the blender reaches a creamy flow. Direct tray contact caramelises pumpkin while dry heat concentrates it. Browned onion and carrot add depth; yoghurt is a tangy garnish rather than the soup's structural fat.

How the flavor stays
Direct tray contact caramelises pumpkin while dry heat concentrates it. Browned onion and carrot add depth; yoghurt is a tangy garnish rather than the soup's structural fat.
A cost rule that survives inflation
Whole pumpkin or butternut keeps well, and onion, carrot, stock, and plain yoghurt have many other uses. No cream carton is opened for a single soup.

Method
Each step includes heat, a visible cue, and a recovery.
Step 1 · follow the visible cue
Roast pumpkin cut-side down
Heat oven to 220°C. Rub cut faces with one teaspoon oil and place flat on a dark tray. Roast 35–40 minutes.
Look for: A knife slides through the neck and the cut surface has broad caramel-brown patches.
Step 2 · follow the visible cue
Brown the aromatics while pumpkin cools
Cook onion and carrot in remaining oil over medium for 8 minutes. Add garlic and cumin for 30 seconds, then deglaze with 1 cup stock.
Look for: Onion has gold edges and every brown mark lifts into the first stock addition.
Step 3 · follow the visible cue
Blend with less stock first
Scoop roasted flesh into the pot and add another 2 cups stock. Blend smooth, then add remaining stock in small pours only as needed.
Look for: The blender vortex moves freely, yet a spoon trail closes slowly rather than disappearing at once.
Step 4 · follow the visible cue
Simmer briefly and garnish by measure
Simmer 5 minutes, season, and divide into five bowls. Top each with 30g yoghurt and 6g pepitas.
Look for: The soup coats the spoon in a smooth film and yoghurt remains a visible tangy swirl.

The estimate uses the listed ingredients divided into 5 servings. Brand labels, trimming, and the amount left in the pan can change the result.
Keep the leftovers in the same spirit
Refrigerate up to 4 days or freeze the soup without yoghurt for up to 3 months. Thin after reheating because pumpkin continues absorbing liquid.

Frequently asked questions
Can I use pre-cut pumpkin?
Yes. Roast chunks in one layer and turn once, but expect less concentrated browning than a large cut face against the tray.
Are yoghurt and pepitas included?
Yes, at 30g yoghurt and 6g pepitas per bowl. Bread is separate.
