Smooth Oatmeal Congee | IDDSI Level 3 Recipe

IDDSI Level 3 (Liquidised) | 20 minutes | Easy

Oatmeal cooked with a generous ratio of liquid and blended thoroughly until completely smooth — no grains, no fibrous texture, just a flowing, naturally velvety consistency. The soluble fibre in oats (beta-glucan) creates a naturally smooth and cohesive texture when fully cooked and blended, often reaching IDDSI Level 3 without any added thickeners, making this a practical and nutritious breakfast option for residents with dysphagia.

Ingredients (2–3 servings)

Main:

• 80g rolled oats or quick oats (quick oats cook faster and blend more easily)
• 800ml water or low-sodium chicken stock (high liquid ratio maintains flowability)
• ¼ teaspoon salt

Seasoning (optional):

• ½ teaspoon sesame oil
• ½ teaspoon ginger juice (for flavour; no solid ginger pieces)

Method

1. Bring the stock or water to a boil in a saucepan. Add the oats and stir to combine.
2. Reduce to a medium-low simmer, stirring frequently, and cook for 10–12 minutes until the oats are completely soft and have absorbed most of the liquid. For rolled oats, allow 15–18 minutes.
3. Remove from heat. Using a stick blender, blend thoroughly in the pot for at least 60 seconds until completely smooth with no grain or fibrous texture remaining.
4. If the consistency is too thick, add hot stock or hot water in small amounts and stir. Check flowability by tilting a spoon — the oatmeal should flow freely.
5. Season with salt and sesame oil to taste. Serve immediately.

Texture Test

Flow test: Passes Level 3 — tilting a loaded spoon allows the oatmeal to flow freely, spreading flat in the bowl within 5 seconds. No fixed shape is maintained.

Particle check: No oat pieces, grain husks or fibrous strands visible or palpable after blending. Texture is uniform throughout.

Spoon test: Flow rate is similar to a thick soup — not water-thin, but flows freely without clumping on the spoon.

Safety Notes

⚠️ Blend thoroughly — oat fibres can form small threads if not fully processed. Blend for at least 60 seconds. Consider straining through a fine-mesh sieve for residents with very sensitive swallowing.

⚠️ Monitor consistency after standing — beta-glucan continues absorbing liquid after cooking. Oatmeal thickens significantly within 10 minutes at rest. Recheck flowability immediately before serving and reheat with extra water if needed.

⚠️ Temperature — oatmeal retains heat well. Check serving temperature with a thermometer and allow to cool to 60–65°C before serving to avoid oral burns.

⚠️ No solid add-ins — fresh fruit pieces, nuts, seeds or solid garnishes are not suitable for Level 3. Use only smooth, blended flavouring agents such as ginger juice or sesame oil.

Sourcing in Hong Kong

• Oats: Available at PARKnSHOP, Wellcome and most supermarkets; choose plain rolled oats or quick oats with no added flavourings or sugar; Quaker and Bob’s Red Mill are widely available
• Low-sodium chicken stock: Carton or canned low-sodium stock adds flavour while managing sodium intake; available at all major supermarkets

Nutrition

Approximately 120 kcal per serving (about 250ml), 4g protein, 3g fibre. Oats are an excellent source of soluble fibre (beta-glucan), which supports blood sugar regulation and cholesterol management — relevant for elderly residents with diabetes or cardiovascular conditions. Using stock instead of water adds protein and minerals. One teaspoon of olive oil added at serving increases calorie density by approximately 40 kcal for residents needing supplemental energy.

Cultural Note

Oatmeal has gained widespread acceptance in Hong Kong as a healthful breakfast, particularly among health-conscious older adults. Providing an IDDSI Level 3 oatmeal option extends this familiar, modern food to residents with dysphagia — ensuring that swallowing difficulties do not exclude them from the broader healthy-eating choices available in contemporary Hong Kong food culture.
