Red Lentil Soup
Red lentils break down into a smooth, thick base within thirty minutes, making this an ideal weeknight meal. You start by sweating aromatic vegetables until softened, simmer the lentils in broth until they collapse, and finish with a bright splash of acid to cut the earthiness of the pulses.
Consistency is about timing, not blending.
Red lentils lose their shape quickly when simmered. Do not overcook them into a watery paste; aim for a thick, porridge-like texture that still holds a bit of grain.

What goes in.
- 1.5 cupsdry red lentils, rinsed
- 1 largeyellow onion, finely diced
- 2carrots, peeled and small-diced
- 3 clovesgarlic, minced
- 1 tspground cumin
- 6 cupsvegetable or chicken stock
- 2 tbspolive oil
- 1lemon, juiced
- to tastesea salt and black pepper
The foundation of depth
Cook the onions and carrots over medium-low heat until the onions are translucent and the carrots lose their raw snap. Adding the cumin at the very end of this phase toasts the spice and releases its oils without burning it.
The method.
Heat the base
Warm the olive oil in your pot over medium heat. Add the onion and carrots, stirring occasionally until they soften and the onion turns pale gold, about 8 minutes.
Bloom the aromatics
Stir in the garlic and cumin. Cook for 60 seconds until the garlic becomes fragrant but not browned.
Simmer
Add the rinsed lentils and the stock. Bring the liquid to a boil, then immediately reduce to low. Keep the pot partially covered and simmer for 20 to 25 minutes.
Check the texture
The lentils are done when they have fully disintegrated and the soup has thickened. The soup should coat the back of your spoon.
Finish and serve
Remove from heat. Stir in the lemon juice and season with salt and pepper. Serve immediately while hot.
Other turns to take.
Greens addition
Stir in two large handfuls of baby spinach or chopped kale once the soup is finished; the residual heat will wilt them in seconds.
Spiced oil
Heat a tablespoon of butter with a pinch of red chili flakes and drizzle over individual bowls before serving.
When it doesn't go to plan.
Always rinse your lentils in a fine-mesh sieve under cold water until the water runs clear to remove any dust or debris.
If the soup thickens too much while sitting, stir in a quarter-cup of hot water or stock to loosen the consistency before reheating.
Do not salt the water until the end, as salt can sometimes toughen the skins of legumes while they cook.

Why did my lentils turn into a mush?
Red lentils are structurally different from green or brown lentils; they are meant to break down. If you prefer more texture, use brown or black (Beluga) lentils instead, though they require a longer cooking time.
Can I use water instead of stock?
You can, but you will need to be more generous with your salt and perhaps add a bay leaf to the simmering liquid to build flavor.
