πŸ›’ Ingredient notes

Ingredients for celeriac and bacon soup.

Celeriac β€” Use one medium celeriac (about 500–600g). Peel the tough outer skin and cut the flesh into small cubes so it cooks evenly and purees smoothly.

Bacon β€” Smoked bacon lardons add depth and smoky flavour. Dry-fry until crisp, then use half in the soup and reserve the rest to garnish each serving.

Onion & Garlic β€” One onion, peeled and chopped, and two garlic cloves, finely chopped, form the aromatic base.

Dried thyme β€” A teaspoon of dried thyme complements the celeriac. Fresh thyme or rosemary can be used instead if you prefer.

Stock β€” Use chicken or vegetable stock (approximately 850 ml) made from a cube or pot for convenience.

Salt & Pepper β€” Season to taste; start conservatively and adjust at the end.

Double cream β€” Stir in a couple of tablespoons at the end for a smooth, indulgent finish.

Parsley β€” Fresh chopped parsley brightens the finished soup when sprinkled on top.

3. Add the cubed celeriac, chopped onion, garlic, half the crispy bacon, dried thyme, stock, salt and pepper to the soup maker. Select the smooth setting (or a chunky setting if you prefer texture) and start the programme. Typical cook time in a 1.6 L soup maker is around 20–22 minutes.

4. When the programme ends, stir in the double cream to taste. Serve hot in bowls topped with the reserved crispy bacon and a sprinkle of chopped parsley.

Top tips

  • Use a sharp knife rather than a peeler to remove celeriac’s knobbly skin β€” it’s safer and faster for this root vegetable.
  • Cut the celeriac into small, even pieces so it cooks quickly and purees evenly.
  • Do not exceed the maximum fill line of your soup maker; liquids expand during cooking and overfilling can cause spills or interfere with blending.
  • To deepen flavour, gently sweat the onion and garlic in a little oil before adding to the soup maker, or add a bay leaf while cooking and remove it before blending.
  • Leftovers thicken as they cool; add a splash of stock or water when reheating if you prefer a looser consistency.

🍴 Serving suggestions

Serve this hearty soup with warm, crusty bread, garlic bread, cheese scones, or a slice of homemade focaccia. For extra texture, top bowls with homemade croutons β€” cube stale bread, toss with olive oil and herbs, then bake until crisp. A green salad or simple slaw makes a fresh side.

πŸ“– Variations

  • Add a bay leaf while cooking for additional depth (remember to remove it before blending).
  • Swap onion for sliced leeks for a milder, sweeter base.
  • Add one or two diced potatoes for a thicker, more filling soup.
  • Include a peeled, chopped apple for a subtle sweetness that complements the smoky bacon.
  • Stir in crumbled blue cheese or feta at the end for a tangy, creamy finish.
  • Fold in cooked, chopped chestnuts for a nutty autumnal variation.

πŸ₯‘ Storage

Store: Cool completely, transfer to an airtight container and refrigerate for up to 3–4 days.

Freeze: Freeze in suitable containers for up to 3 months. Thaw overnight in the fridge before reheating.

Reheat: Warm gently on the hob over low to medium heat, stirring occasionally, or heat in a microwave in short bursts and stir between intervals to ensure even warming.

❓ Frequently asked questions

Can I make this soup without a soup maker?

Yes. SautΓ© the bacon, onion and garlic in a large pot, add the celeriac and stock, then simmer until the celeriac is tender. Blend with a handheld blender or transfer to a blender and puree until smooth.

Do I need to peel the celeriac?

Yes. The skin is tough and knobbly, so peel or trim it away with a sharp knife to reveal the smooth flesh underneath.

Is celeriac low-carb?

Celeriac tends to be lower in carbohydrates than potatoes, making it a good option if you are looking to reduce starchy carbs.

Can I add other vegetables?

Absolutely. Potatoes, parsnips, leeks, carrots or cauliflower can all be added to increase volume and variety.
