Step-by-Step Instructions
Making sweet potato and lentil soup is quick, simple, and perfect for busy parents or even during nap-time cooking. To begin with, here’s how to do it:
Step 1. Start by heating olive oil in a medium pot. Add the diced onion and garlic, and sauté until soft and fragrant.

Frequently Asked Question
Can I use green lentils instead of red?
You can, but the texture will be firmer and the cooking time may be longer. Red lentils break down more easily, which is why they’re best for toddlers.
Can I make this sweet potato and lentil soup ahead of time?
Absolutely! This soup stores well in the fridge or freezer. It’s great for meal prep days.
Can I blend it completely for babies?
Yes! For early eaters, fully blend the soup to a smooth consistency. You can also thin it with breastmilk or formula if needed.
Is it okay to use frozen sweet potatoes?
Yes, frozen sweet potato chunks work well. Just make sure they’re soft before blending.
What if my toddler doesn’t like the flavor?
Try mixing in a spoonful of plain yogurt or serving it with fun “toast fingers” for dipping. Sometimes the presentation makes all the difference.
What can I serve it with?
This sweet potato and lentil soup is satisfying on its own, but pairing it with toddler-friendly sides can make it even more fun.

You can also top it with plain yogurt, mashed avocado, or a sprinkle of grated cheese to add creaminess and appeal. Because it’s such a simple base, it pairs beautifully with almost anything your little one already enjoys.
