Instructions

1. 1

   Heat the oven

   Preheat the oven to 220°C (425°F). Line a large baking tray with foil and drizzle it with a little olive oil.

2. 2

   Roast the potatoes

   Peel the sweet potatoes, cut them into chunks and quarter the chunks. Put them on the prepared tray and toss gently to coat with oil. Roast for 40–45 minutes, until lightly browned and crisp.

3. 3

   Cook the pancetta

   Halfway through roasting the sweet potatoes, melt the butter in a large stockpot or Dutch oven over a medium heat. Add the pancetta and cook, stirring, for about 5 minutes, until cooked through. Lift it out and set it aside in a small bowl lined with kitchen paper.

4. 4

   Sauté the vegetables

   Add the onion to the same pot and cook for 3–4 minutes, until translucent. Add the celery and carrot, stir and cook for another 3 minutes. Stir in the garlic and cook for 1–2 minutes, until fragrant.

5. 5

   Season the base

   Stir in the salt, pepper, smoked paprika, allspice and ground ginger until evenly combined.

6. 6

   Simmer the soup

   Add the roasted sweet potatoes, chicken stock and coconut milk, then stir to combine. Cover and simmer for 15 minutes. While it simmers, prepare the grilled cheese sandwiches. If you like, trim off the crusts and cut the sandwiches into small squares for croutons.

7. 7

   Blend until smooth

   Take the pot off the heat and remove the lid. Blend the soup with an immersion blender to your preferred consistency, then taste and adjust the seasoning.

8. 8

   Serve the soup

   Serve warm with grilled cheese sandwiches or croutons and the reserved diced pancetta on top.

What is roasted sweet potato soup?

This is a thick, savoury soup built around roasted sweet potatoes, with onion, celery and carrot forming its aromatic base. Sweet potatoes are native to the Americas, and this American-style version pairs their natural sweetness with warm spices and creamy coconut milk.

Roasting deepens the potatoes’ flavour before they go into the pot. Grilled cheese and crisp pancetta make the smooth soup feel more substantial and add a welcome crunchy, savoury finish.

Nutrition and macros by portion

The nutrition label shows one serving as written: 446 calories, 8g protein, 37g carbs, 30g fat.

Most of the carbohydrates come from the sweet potatoes and vegetables, while coconut milk, butter and pancetta contribute much of the fat. The chicken stock, pancetta and grilled cheese provide protein, though the amount depends on how much sandwich is served. Balance a bowl with a side of greens, and treat the grilled cheese as a topping or side according to your appetite.

Roast for deeper flavour

Sweet potatoes: cut them into fairly even chunks so they soften at a similar rate. Spread them out on the tray and toss them lightly with oil to help them brown.

Colour: give the pieces the full 40–45 minutes, checking near the end for browned edges and tender centres. If the tray is crowded, they may soften without crisping as much.

Build the flavour in the pot

Pancetta: cooking it first renders some fat into the pot and gives you crisp pieces to use as a topping. Set it aside on kitchen paper while the vegetables cook.

Aromatics: soften the onion, celery and carrot before adding the garlic. Stir the spices in before the liquids so they are distributed through the vegetable base.

Blend to your preferred texture

Simmering: the 15-minute covered simmer brings the roasted potatoes and stock together and lets the flavours mingle. Keep the heat gentle rather than letting the soup boil hard.

Consistency: blend after taking the pot off the heat, stopping when the soup is as smooth as you like. Take care with hot liquid and keep the blender head submerged to reduce splashing.

Make the toppings count

Grilled cheese: cut the sandwiches into small squares if you want crouton-sized pieces, or serve them whole for dipping. Add them just before eating so they keep some texture.

Pancetta: scatter the reserved pieces over the soup at the end. Adding them at the table helps them stay crisp rather than softening in the pot.

Serve it as a meal

The soup’s creamy texture and sweet, spiced flavour pair well with the salty pancetta and toasted cheese. A simple green salad or steamed greens alongside can add freshness to the meal.

For a tidy finish, ladle the soup into bowls first, then add the toppings. Keep extra grilled cheese on the side for dipping.

Recipe notes & tips

• Cut the sweet potatoes into evenly sized pieces for more consistent roasting.
• Keep the pancetta aside until serving to preserve its crisp texture.
• Let the vegetables soften before adding the garlic so it does not scorch.
• Taste the soup after blending, then add more salt or pepper if needed.
• Blend in batches if your immersion blender does not reach comfortably into the pot.
• Prepare the grilled cheese while the soup simmers to make good use of the cooking time.

Variations

• Add chilli: Stir in a pinch of chilli flakes with the other spices for a little heat.
• Use vegetable stock: Swap in vegetable stock for a meat-free soup, and leave out the pancetta.
• Change the garnish: Top with toasted pumpkin seeds instead of pancetta for a crunchy finish.
• Make it extra smooth: Blend thoroughly, then pass the soup through a sieve if you prefer a very fine texture.
• Add fresh herbs: Finish each bowl with chopped coriander or parsley for a fresh note.

Common mistakes to avoid

• Crowded baking tray: the potatoes can steam rather than brown; spread them out or use a second tray.
• Uneven chunks: pieces may finish roasting at different times; cut them to a similar size.
• Burnt garlic: it can turn bitter if cooked too long; add it after the other vegetables and stop once fragrant.
• Boiling hard: the soup may splatter and cook unevenly; keep it at a gentle simmer with the lid on.
• Blending while bubbling: hot soup can splash; take the pot off the heat before blending.
• Early topping: grilled cheese and pancetta soften in the soup; add them just before serving.

How to store

Store leftover soup in an airtight container in the fridge for up to 3 days, keeping the grilled cheese and pancetta separate. Reheat gently in a saucepan, stirring occasionally, or microwave in short intervals; add the toppings after reheating.
