Indian Lentil and Spinach Curry in Coconut Milk Recipe
Red lentils soften into a thick, spoonable curry while spinach keeps the finished dish earthy and fresh. Coconut milk rounds out the cumin, coriander, turmeric, and hot paprika without hiding their warmth, and lemon juice added off the heat gives the rich sauce a clean finish. The recipe makes about four servings.
This is most accurately described as an Indian-inspired lentil curry rather than a preparation tied to one specific Indian region. Its ground spices, onion-tomato base, lentils, and coconut milk draw on familiar Indian cooking patterns, but it does not use the separate tempering or other defining details associated with many regional South Indian dals.
The appeal lies in the contrast between creamy, broken-down lentils and distinct green ribbons of spinach. Coconut milk softens the paprika’s heat, while the final lemon juice prevents the curry from tasting heavy or overly sweet.
Why this version works
- Cooking the onion until lightly golden builds sweetness before the garlic, ginger, and ground spices are added.
- Briefly frying the spices in oil releases their aroma without giving the paprika time to scorch.
- The lentils cook in water before the coconut milk is added, allowing them to soften efficiently while preserving the coconut milk’s smooth flavor.
- Squeezing thawed spinach keeps excess water from diluting the curry.
- A measured 3/4 teaspoon salt, added in stages, seasons the onion, tomato base, and finished curry evenly.
Chef's tips
Use a saucepan with enough room for the lentils to foam when they first reach a boil. If the curry becomes very thick during the final simmer, lower the heat rather than cooking it aggressively; the intended texture is creamy and spoonable, not dry or pasty.
How to serve
Serve hot with steamed rice for a soft, comforting meal or with bread for scooping. This quantity provides about four moderate servings, and the curry should be stirred before serving because it thickens as it rests.
Watch out for
- Ground spices can turn bitter quickly. Add the tomatoes after no more than 30 seconds if the pan looks dry or the spices begin to darken.
- Red lentils settle as they soften, so scrape across the entire bottom of the pan every few minutes to prevent sticking.
- Do not judge the final thickness while the curry is boiling. Let it stand for 3 minutes; the lentils absorb more liquid as they cool slightly.
- Unsqueezed frozen spinach may make the sauce watery and can mute the seasoning.
Substitutions
- Use 200 g fresh or frozen spinach. Thaw and firmly squeeze frozen spinach before adding it.
- The 200 g chopped tomatoes may be canned or freshly chopped ripe tomatoes; fresh tomatoes may need an extra minute or two to become pulpy.
- Full-fat or light coconut milk can be used in the same quantity. Full-fat coconut milk produces a richer, thicker sauce, while light coconut milk leaves it somewhat looser.
Ingredients
- red lentils dry, rinsed - 250 g
- spinach fresh or frozen, leaves - 200 g
- coconut milk - 300 ml
- water for cooking the lentils - 500 ml
- onion finely chopped - 1 piece
- chopped tomatoes from a can or fresh - 200 g
- garlic pressed - 3 cloves
- fresh ginger grated - 2 cm
- vegetable oil - 2 tablespoons
- ground cumin - 1 teaspoon
- ground coriander - 1 teaspoon
- turmeric - 0.5 teaspoons
- hot paprika or less, to taste - 0.5 teaspoons
- salt to taste
- lemon juice - 1 tablespoon
Preparation
- Rinse the red lentils in a fine-mesh sieve under cool running water for 1–2 minutes, moving them with your fingers, until the draining water is only slightly cloudy. Drain well.
- Finely dice one medium onion, mince the garlic, and finely grate the ginger. If the spinach leaves are large, roughly chop them. For frozen spinach, thaw it completely and squeeze out as much water as possible.
- Heat the vegetable oil in a medium saucepan over medium heat until it shimmers. Add the onion and 1/4 teaspoon salt. Cook for 5–7 minutes, stirring occasionally, until soft and pale golden around the edges.
- Stir in the garlic and ginger and cook for 45–60 seconds, just until their raw aroma fades. Add the cumin, coriander, turmeric, and hot paprika; stir continuously for 20–30 seconds so the spices become fragrant without darkening.
- Add the chopped tomatoes and another 1/4 teaspoon salt. Cook for 5–7 minutes, stirring and pressing the tomatoes against the pan, until the mixture looks pulpy and a spatula drawn across the bottom leaves a visible trail for a moment.
- Stir in the drained lentils and 500 ml water. Bring to a boil, then immediately lower the heat to maintain a gentle simmer. Cook uncovered for 15–18 minutes, stirring and scraping the bottom every 3–4 minutes, until the lentils have mostly collapsed and the mixture is thick but still loose.
- Stir the coconut milk thoroughly before measuring, then add all 300 ml to the pan. Simmer gently, uncovered, for 5–7 minutes. Avoid a hard boil; the curry is ready for the spinach when it coats the back of a spoon but still falls from it easily.
- Fold in the spinach. Cook fresh spinach for 2–3 minutes, or thawed and squeezed frozen spinach for 3–4 minutes, until evenly distributed and hot. Remove from the heat, stir in the lemon juice and the remaining 1/4 teaspoon salt, then taste and adjust only if needed. Let the curry stand for 3 minutes before serving, as it will continue to thicken.
Storage
The curry thickens after chilling, so when reheating add a little water. After defrosting, stir well, as the sauce may separate slightly.
I prefer adding the lemon only after the pan leaves the heat. Its brightness is clearer that way, and it brings the coconut, spinach, and warm spices into balance without making the curry sharply acidic.
