Level 3 — Liquidised

Blended Vegetable Soup

Smooth, sieved vegetable soup blended to a pourable consistency meeting IDDSI Level 3 (Liquidised) — no lumps, fibres, or skin fragments.

Natural IDDSI Level

Vegetable soup in its natural form contains chunks and fibres (Level 6–7). Thorough blending and sieving removes all particles, producing a homogeneous pourable liquid suitable for Level 3. The high water content means it naturally flows; the vegetable solids provide flavour and micronutrients without texture risk.

Safe Preparation

Cook vegetables (carrot, potato, zucchini, or pumpkin) until very soft. Blend the entire batch with cooking liquid in a high-powered blender for 2 minutes. Pass through a fine-mesh sieve pressing solids through. Discard any fibrous residue in the sieve. Adjust consistency with warm stock — it should pour freely and continuously.

  • ✓Avoid high-fibre vegetables (celery, leek tops, kale) — they leave stringy residue even after sieving.
  • ✓Blend in batches if using a domestic blender to ensure uniform smoothness.
  • ✓A hand-held immersion blender is not powerful enough alone — always follow with sieving.
  • ✓Season after blending; salt draws out water and can alter consistency.

Important Warnings

  • Never add cream with visible fat globules after blending — it can break the emulsion and create a two-phase liquid unsafe for dysphagia patients.
  • Skin, seeds, and stringy vegetables must be removed before blending.

Frequently Asked Questions

Is blended vegetable soup nutritionally adequate for elderly patients on a liquidised diet?

Blended vegetable soup provides vitamins and minerals but limited protein and energy. For elderly or malnourished patients on a Level 3 diet, enrich the soup with protein powder, olive oil, or fortified stock to meet nutritional targets. Always work with a dietitian to ensure overall dietary adequacy.
