10 min prep, 30 min to cook this nutritious, tasty and easy Red Lentil baby soup recipe. Perfect for 6 month old baby and older. Can be given if you are doing baby-led weaning, for toddlers, kids and it is so delicious adults will love it. Make a big batch and freeze it for days you don't want to cook. It's naturally vegan, dairy-free, and gluten-free.
When autumn comes I just start making a lot of soups and then freezing them so I can minimize daily meal prep. And then we basically eat a soup a day...
And ever since I have adopted more of a vegetarian diet, foods like lentils and chickpeas are eaten almost daily in our household.
So I wanted to make a really good lentil soup which you could also give to a 6-month-old baby and would be enjoyed just as much by a 30-year-old adult.
So here it is...
Why we love this soup:
- Super easy
- Healthy, made with nutritious whole foods
- Simple vegetarian soup for baby
- Low sodium (can be made with or without stock)
- Can be served to 6 month old baby and older toddlers, kids and adults
- Red Lentils - we use red lentils for their sweet and nutty flavor
- Celery and Carrot - the basis of most great soups. Sautéing them with garlic and onion brings out the base flavor of the soup
- Vegetable stock - nutrition and ingredients will vary depending on which you buy. Look for one with minimal sugar, salt and preservatives. Avoid it completely if making for babies under 1, just use water instead and then season the adult portions with salt separately
- Spices and flavoring - using ground cumin and paprika to give a wonderful earthy flavor. Lemon juice and lemon zest are a must for that last zing
How to Cook Red Lentil Soup for Baby
1. Sauté the veggies. Heat oil in a large pot over medium-high heat. Add onion, garlic, celery and carrots and sauté for about 5 minutes, stirring occasionally, until the onions are soft and translucent (photo 1).
2. Bring to boil by adding vegetable broth (or water if making for babies), lentils, ground cumin, paprika, and black pepper (photo 2).
3. Simmer. Once brought to boil, lower heat, cover and simmer for about 30 minutes until the lentils are fully cooked (photo 3).
4. Season and blend. Add lemon zest and lemon juice, salt, and stir (don't add salt if making for babies under 1). Blend with an immersion blender or Vitamix to make the soup creamy and smooth (photo 4). Serve for yourself and for baby.
This soup pairs really well with the Easy Wholewheat No-Knead Bread.

If you still want to serve soup to baby but this may be too many ingredients or are worried about the flavors, you can start with a simple clear chicken soup (chicken broth) recipe we have here which is nutritious and full of flavor.
- Create flavor by taking your time to sauté the onion, garlic, celery, and carrots to bring out the flavors before adding vegetable broth.
- Serve warm with freshly baked bread.
From 6 months old onwards as long as you replace the vegetable broth with water so there is no added sodium in the recipe.
Soup is basically like any other puree recipe for a baby so this is a perfect nutrient-rich meal for your baby.
Store in the fridge in an airtight container for 3 days and in the freezer for up to 3 months. We use these cool pods to store soup in baby portions.
You can, but the flavor may not be as nice. If you have time, it's best to sauté the onion, garlic, celery and carrot before adding vegetable broth to bring out the flavors.
Yes, but then it may not be suitable for very young babies until they can properly chew depending on the size of the vegetables.
Possible Recipe Variations
- Make it spicier by adding chili flakes or cayenne pepper to the mix (for adults).
- Add cheese on top. Feta cheese would work great crumbled on top for the adults (although it has too much sodium for babies).
- Serve the soup chunky. If you don't have a blender or prefer chunky soups this one can easily be served chunky depending on how able your baby is to chew chunkier vegetables.
