Sweet Potato & Lentil Fritters

Serves

8–10 fritters

Ingredients

• 2 medium sweet potatoes

• ⅜ cup dried red lentils (75g)

• 1 tsp garlic (minced or paste)

• ½ tsp paprika

• 1 tsp ground cumin

• ¾ tsp salt (omit if cooking for babies)

Method

1. Cook the sweet potatoes by roasting or microwaving until soft. Allow to cool, peel off the skin, and mash until smooth.

2. Cook the lentils by adding them to a saucepan with ⅔ cup of water. Bring to a boil, then simmer for 10–15 minutes until soft. Drain any excess water and mash lightly.

3. Add the mashed sweet potato, lentils, garlic, spices, flour and egg (or flax egg) to a large bowl. Mix well.

4. If the mixture feels too runny, add a little more flour. The batter should be soft and slightly sticky.

5. Heat oil in a large non-stick pan over medium heat.

6. Spoon the mixture into the pan and shape into small patties.

7. Cook for about 5 minutes on each side, until golden and crisp.

Why Lentils and Sweet Potatoes Promote Gut Health

This recipe combines two common gut-friendly ingredients:

Sweet potatoes

Sweet potatoes, which are high in soluble fibre and polyphenols, promote regular digestion and nourish good gut flora. In the UK, the average daily consumption of fibre is approximately 18g, which is significantly less than the recommended 30g.

Red lentils

Research has demonstrated that lentils, a potent source of plant protein and prebiotic fibre, enhance the makeup of the gut microbiota and promote regular bowel movements.

Gut-Friendly Benefits 

• It's high fibre content, which supports microbiota balance and digestion.

• Plant-based protein for blood sugar regulation and fullness

• Naturally gluten-free (use flour if necessary)

• Spices that reduce inflammation (paprika and cumin)

• Fit for toddlers, families, and baby-led weaning (with modifications)

In the UK, one in five people report experiencing frequent bloating or gastrointestinal problems, which are frequently caused by a diet high in processed foods and poor in fibre.

As part of a healthy, gut-supporting eating pattern, meals that include lentils, veggies, and mild spices are recommended.

Tips & Variations

• For babies: omit salt and spices, and cook fritters thoroughly

• Make them gluten-free using chickpea or oat flour

• Add grated courgette or carrot for extra fibre

• Serve with yoghurt, hummus or avocado for added gut support

Without sacrificing flavour, these sweet potato and lentil fritters are an easy way to feed your stomach entire, high-fibre foods. When consumed on a daily basis, meals such as these can have a significant impact in a nation where the consumption of fibre is constantly low.
