Clear Vegetable, Rice & Tofu Soup for an IBS Flare Day

Preparation Steps

1. Prepare the vegetables carefully. Slice the carrots into thin rounds, approximately 3mm thick, to reduce cooking time and aid digestion. Cut the courgette into half-moons of the same thickness. Finely slice the fennel and celery stick. Snip only the green part of the spring onion stems — the white part contains higher levels of FODMAPs and should be discarded. Set all the vegetables aside separately.

2. Prepare the tofu. Drain the firm tofu and pat it thoroughly dry with kitchen paper to remove excess moisture. Cut it into small, even cubes of roughly 1.5cm. Uniform pieces ensure even cooking and a pleasant texture throughout the soup.

3. Rinse the rice. Place the basmati rice in a bowl, cover with cold water and rub the grains gently between your fingers. Drain and repeat twice until the water runs nearly clear. This removes excess surface starch and prevents the soup from becoming too thick or stodgy.

4. Heat the stock. Pour the vegetable stock into a large, heavy-bottomed saucepan and bring it to a gentle simmer over a medium heat. A clear, light stock is essential here — it hydrates, warms and soothes the gut lining without overloading it. If using homemade stock, ensure it has been strained and is completely free from pieces of onion or garlic.

5. Add the rice and harder vegetables first. Once the stock is simmering, stir in the rinsed rice and the sliced carrots. Cook over a medium-low heat for 8 minutes. Both the carrots and the rice need a little more time than the other vegetables to reach a tender, easily digestible texture.

6. Add the softer vegetables. After 8 minutes, add the sliced fennel, celery and courgette, along with the freshly grated ginger. Stir gently and continue cooking for a further 5 minutes over a low heat. Fennel and celery are both well regarded for their soothing properties on the digestive system and their ability to reduce feelings of bloating.

7. Add the tofu gently. Carefully lower the tofu cubes into the soup without stirring too vigorously — you want to keep them intact. Allow them to warm through for 3 to 4 minutes. Firm tofu requires very little cooking time; the aim here is simply to heat it through and let it absorb the flavours of the stock.

8. Check the seasoning and keep it light. Taste the soup. The rice should be tender but not mushy, and the vegetables soft without falling apart. Add a pinch of salt if needed. During an IBS flare, it is best to keep seasoning very minimal — spicy ingredients or shop-bought sauces can aggravate intestinal irritation.

9. Finish with olive oil off the heat. Remove the saucepan from the heat and drizzle in the tablespoon of olive oil. Adding the oil at the very end preserves its polyphenols and improves the absorption of carotenoids from the carrots, without making the soup feel heavy.

10. Serve and garnish gently. Ladle the soup into warmed bowls. Scatter over the snipped green spring onion tops and a few leaves of fresh parsley or coriander. If you wish and tolerate it well, add a very small squeeze of lemon juice for a subtle brightness that lifts the flavour without irritating the gut. Serve warm rather than piping hot — very high temperatures can further aggravate an already sensitive gut lining.

💡 Gut-Friendly Tips & Adaptations

During a very active flare, simplify the recipe further: keep only the stock, rice and well-cooked carrot, then gradually reintroduce the remaining ingredients as your symptoms ease.

To get that garlic flavour without the FODMAPs, gently warm a whole, uncut garlic clove in the olive oil for a few minutes, then remove it before adding the oil to the soup. The aromatic compounds from the garlic infuse into the oil, but the FODMAPs (fructans) remain in the flesh and do not transfer into fat.

Storage: this soup keeps for up to 2 days in the fridge in an airtight container. The rice will absorb some of the stock as it sits — simply add a splash of water or warm stock when reheating. Reheat very gently over a low heat to preserve the texture of the tofu and vegetables.

Variations depending on tolerance: replace the courgette with butternut squash (a modest portion of around 75g per serving), or stir in a handful of spinach leaves right at the end of cooking for an extra boost of folate and minerals. Avoid broccoli, cabbage, onion and the white part of leeks, which are more fermentable and poorly suited to a flare-up.

A note to keep in mind: this recipe is designed as a comforting meal during a flare, not as a nutritionally complete or calorie-sufficient meal for the long term. As your symptoms improve, gradually enrich your meals to restore a broader nutritional balance.
