2 medium sweet potatoes Peeled and diced ½‑inch cubes for even cooking.

2 garlic cloves, minced Provides depth and aroma.

1 tsp ground cumin Warm spice that complements the earthiness.

Instructions

Prep the vegetables

Dice the onion, mince the garlic, and cut sweet potatoes into uniform ½‑inch cubes. Rinse lentils under cold water until the water runs clear.

Pro Tip: Soaking lentils isn’t necessary, but a quick rinse removes dust and improves texture.

Sauté aromatics

Heat 2 tbsp olive oil in a large pot over medium heat. Add onion and sauté 4‑5 minutes until translucent, then stir in garlic and cumin; cook another minute until fragrant.

Pro Tip: Avoid browning the garlic; it turns bitter if over‑cooked.

Combine and simmer

Add rinsed lentils, diced sweet potatoes, and vegetable broth to the pot. Bring to a boil, then reduce to a gentle simmer. Cover and cook 20‑22 minutes, or until lentils are tender and sweet potatoes are soft.

Pro Tip: Stir once halfway through to prevent sticking.

Blend for texture

Using an immersion blender, puree about one‑third of the soup directly in the pot.

Pro Tip: Blend in short bursts to avoid splatter.

Finish with herbs & serve

Stir in chopped cilantro, parsley, and a squeeze of lemon juice. Season with salt and pepper to taste. Ladle into bowls, drizzle a drizzle of olive oil if desired, and enjoy immediately.

Pro Tip: Adding herbs off the heat preserves their fresh flavor.

Expert Tips

Tip #1: Use red lentils

Red lentils break down quickly, giving the soup a naturally creamy texture without extra blending.

Tip #2: Roast sweet potatoes

Roasting cubes 10 minutes at 200 °C before adding deepens sweetness and adds a subtle caramel note.

Tip #3: Adjust thickness

If the soup feels thick, thin with extra broth or water; for a richer mouthfeel, stir in a splash of coconut milk.

Storage & Variations

Store leftovers in airtight containers in the fridge for up to 4 days; reheat gently on the stove, adding a splash of broth if needed. For a spicy twist, stir in a pinch of cayenne or smoked paprika. Swap cilantro for basil or mint to match seasonal herbs.
