Spiced Lentil and Sweet Potato Balls

These spiced lentil and sweet potato balls are a flavorful vegetarian dish, perfect for a quick snack or light meal.

Ingredients

  • 1 cup of red lentils, rinsed
  • 1 large sweet potato, peeled and cubed
  • 1 onion, finely chopped
  • 2 cloves of garlic, minced
  • 1 teaspoon cumin powder
  • 1 teaspoon coriander powder
  • 1/2 teaspoon chilli flakes (optional)
  • Salt and pepper to taste
  • 1 tablespoon olive oil
  • 1/4 cup breadcrumbs
  • Fresh coriander, chopped (optional garnish)

Method

  1. Cook the lentils in a medium saucepan with 2 cups of water, bring to a boil, then simmer for 15-20 minutes until soft and water is absorbed.
  2. Steam sweet potato cubes until tender, about 10-12 minutes.
  3. In a large bowl, mash cooked lentils and sweet potatoes together.
  4. In a pan, heat olive oil over medium heat, sauté onions and garlic until translucent, add cumin, coriander, and chilli flakes, stir for 2 minutes.
  5. Add sautéed onion mixture to lentil and sweet potato mash, mix well, stir in breadcrumbs, season with salt and pepper.
  6. Preheat air fryer to 180°C (356°F).
  7. Shape mixture into small balls, about the size of a golf ball.
  8. Place balls in air fryer basket without overcrowding, cook for 12-15 minutes, turning halfway, until golden brown and crispy.
  9. Garnish with freshly chopped coriander before serving, if desired.

Why this works in an air fryer

Red lentils and sweet potato form a starch-rich mash that sets as surface moisture is driven off. Breadcrumbs absorb excess water and create a rough exterior, while a little oil carries the spices and helps browning in the air fryer’s fast convection. Turning exposes both sides to direct hot airflow.

Equipment notes

Assumes a 5–6 litre basket holding the balls in one spaced layer. In a single-drawer air fryer, cook in batches rather than stacking; in a dual-zone model, split evenly between drawers, shake/turn both at halfway, and expect the smaller load in each drawer to brown 1–2 minutes faster.

Common pitfalls

  • Mixture slumps or sticks to your hands when shaping? The lentils or sweet potato are too wet; add breadcrumbs 1 tablespoon at a time and rest for 10 minutes before rolling.
  • Balls cracking open by minute 8? The mix is too dry or packed too loosely; mash more thoroughly and add 1–2 teaspoons water or olive oil to bind before reshaping.
  • Pale, soft outsides after 15 minutes? The basket is crowded or the surfaces are damp; leave gaps, cook in batches, and extend 3–5 minutes until the edges feel firm.
  • Garlic tastes harsh or burnt? It caught in the sauté stage or on the ball surface; keep the onion mixture at medium heat and stop once translucent and fragrant, not browned.

Variations & substitutions

  • Use panko instead of fine breadcrumbs for a rougher coating; the balls may brown faster, so check from 10 minutes.
  • Swap sweet potato for butternut squash, but steam it until just tender and mash well drained as it can release more water.
  • Use smoked paprika or garam masala in place of some cumin and coriander; the cooking time stays similar but the spices bloom better if still warmed in the oil first.
  • For a gluten-free version, use gluten-free breadcrumbs or ground oats; oats absorb more slowly, so rest the mixture for 10–15 minutes before shaping.

Storage & reheating

Keep cooled balls refrigerated for up to 3 days, then reheat in the air fryer at 170°C for 5–7 minutes, turning once, until hot through and crisp again.
