Carrot and red lentil soup: choose your texture
Make carrot and red lentil soup for four with a gentle simmer, tender vegetables and water added at the end to give the soup the texture you prefer.

Red lentils thicken this soup, carrots bring sweetness and cumin adds a little warmth. There is no need for cream to give the bowl some body. The base makes four portions as a generous starter or a light meal to round out according to your appetite.
Steps
Wash, cut and rinse
Wash and peel the carrots, then cut into rounds about 1 cm thick. Peel and thinly slice the onion. Rinse the lentils in a fine sieve and drain. Keep the rounds similar in size so the carrots become tender together.
Soften the onion without browning
Pour the oil into the saucepan over medium-low heat. Add the onion and stir for about 5 minutes, keeping it pale. Stir in the cumin and carrots, then mix for 1 minute to distribute the spice.
Simmer until tender
Add the lentils and the 1.2 litres of water. Bring to a simmer, lower the heat and partially cover. Allow about 5 minutes to heat up, followed by 24 minutes at a gentle simmer. Stir occasionally, reaching the bottom. Check that the lentils and carrots are tender; cook longer if they resist.
Choose the texture and serve
Turn off the heat. To blend, follow the appliance instructions, immerse the head before switching on and avoid hot splashes. For a rustic texture, mash the carrots with a fork. Loosen with small amounts of water if needed. Season with salt and pepper, stir and serve.
Pointers for success
- Too thick? Add a little water. Too thin? Simmer uncovered for a few more minutes, keeping an eye on the bottom.
- Allow 50 minutes in total, with no rest; any extra cooking adds to this guide time.
Substitutions and limits
- Leave out the cumin for a milder flavour.
- Save green lentils for a separately adapted recipe: their texture and cooking requirements prevent a direct swap for red lentils.
Cook the vegetables before adjusting the thickness
Start with the water listed in the ingredients, then watch the bottom of the pan. A wide saucepan or stronger heat lets more water evaporate. If the mixture thickens while the vegetables are still firm, add a little water and keep cooking: thick does not mean cooked. The red lentil guide explains what the water in this soup is for.
Before blending, check the carrots with a fork: they should mash without resistance. If not, keep cooking. A blender cannot make up for missing cooking time; it has enough on its plate with the pieces. Similar-sized cuts help the carrots become tender together.
Season, serve and plan for leftovers
Adjust the consistency before tasting: added water dilutes the seasoning too. Pour into stable bowls, leaving some room below the rim. If cooking ahead, the preparation planning guide explains cooling and refrigeration precautions.
Reheat the soup and bring back its silky texture
If the soup was cooled properly and kept in the fridge, take out just what you plan to serve. If it has thickened, add a splash of water to the saucepan and stir, running the spoon along the bottom. Add the water a little at a time so the soup still coats the spoon.
Bring the soup to a rolling boil, stirring continuously, as Health Canada recommends when reheating soup. Then turn off the heat, taste, and adjust the salt or pepper if the extra water has softened the seasoning.
After the meal, discard any soup left over from the portion you reheated.
