Spiced Red Lentil Soup With Coconut and Spinach
A warming red lentil soup with coconut milk and turmeric that's heart-healthy, anti-inflammatory, and ready in about 35 minutes.
Ingredients
| red split lentils | 1 cup |
| coconut milk | 1 can (398ml) |
| diced tomatoes | 1 can (796ml) |
| vegetable broth | 2 cups (450ml) |
| onion, diced | 1 medium onion |
| garlic, minced | 3 cloves |
| baby spinach | 2 large handfuls |
| ground cumin | 1 tsp |
| ground turmeric | 1 tsp |
| ground coriander | 1/2 tsp |
| 1/4 tsp chili flakes | 1/4 tsp |
| olive oil | 1 tbsp |
Steps
- 1Heat the olive oil in a large pot over medium heat. Add the diced onion and cook for 5 to 6 minutes, stirring occasionally, until softened and translucent.
- 2Add the minced garlic, cumin, turmeric, coriander, and chili flakes. Stir for about 1 minute until fragrant, which is your cue that the spices have actually bloomed in the oil rather than just sitting on top of it.
- 3Rinse the lentils under cold water, then add them to the pot along with the diced tomatoes, coconut milk, and vegetable broth. Stir to combine.
- 4Bring to a boil, then reduce to a steady simmer. Cook uncovered for 20 to 25 minutes, stirring occasionally, until the lentils are fully soft and starting to break down into the broth. The soup thickens on its own as this happens; no cornstarch required.
- 5Stir in the baby spinach and cook for 1 to 2 minutes, just until wilted.
- 6Taste, adjust salt, and serve with a squeeze of fresh lemon.
There is a specific kind of cold, grey evening that calls for exactly one thing: a pot that smells like turmeric and coconut before you have even tasted it. This red lentil soup with coconut milk gets there in about 35 minutes, and it happens to be doing a lot of quiet nutritional work while it is at it.
What Makes This an Easy Weeknight Soup
Red split lentils are the reason this comes together so fast. Unlike most dried beans, they need no soaking and break down into a thick, creamy texture on their own, which is what turns this from a thin soup into something closer to a light stew if you let it simmer a few extra minutes. If you prefer it thinner, splash in a little extra broth or water near the end. Craving more heat? A pinch of extra chili flakes or a spoonful of harissa stirred in at the end does the job. It keeps well in the fridge for about four days and tends to taste even better the next day, once the spices have had time to settle into the broth. Reheat gently on the stove with a splash of water to loosen it back up.
How many calories are in a serving of this red lentil soup?
Each serving is approximately 310 calories, based on standard ingredient values. This is an estimate rather than a lab-verified figure, since exact calories depend on specific brands and portion sizes used.
Can I make this red lentil soup vegan?
Yes, it already is. Every ingredient, including the coconut milk base instead of dairy cream, is plant-based, which makes it a straightforward fit for a vegan or dairy-free diet without needing any substitutions.
Is this soup a good option for people managing diabetes?
Red lentils are high in soluble fibre, which can help slow the rise in blood sugar after a meal, and the recipe has no added sugar. That said, this is general nutrition information, not individualized dietary advice, so anyone managing diabetes should check with a doctor or dietitian about how it fits their specific plan.

Red lentils are one of the better plant-based sources of both protein and soluble fibre, a type of fibre that slows how quickly your body absorbs glucose from a meal, which is part of why lentils are often recommended for people managing blood sugar or cholesterol, a link well documented by Harvard's Nutrition Source. Turmeric's curcumin content is linked in research to anti-inflammatory effects that may support cardiovascular health over the long run, which fits into the bigger picture Medimap covers in why so many adults end up living with chronic inflammation: food patterns are only one piece, but they are a piece you actually control. Spinach rounds things out with iron, folate, and vitamin K, so this bowl is doing real nutritional work without asking much extra of you in the kitchen. One honest caveat: legumes like lentils are a common trigger for digestive bloating in people sensitive to FODMAPs, so if that describes you, start with a smaller bowl and see how you feel.
