Red Lentil and Spinach Dal: A Complete, Easy-to-Digest Recipe

Red lentil and spinach dal is made by cooking red lentils (masoor dal) until they break down, then stirring in fresh chopped spinach toward the end of cooking, all finished with a tadka — spices sizzled in ghee and poured over the dish just before serving. Heartier than a simple soup, it's a complete meal in its own right, somewhere between our already-published mung dal and red lentil coconut soup.

Why red lentils rather than another legume?

Red lentils are split and hulled, which makes them much faster to cook (about 20 minutes) and generally easier on sensitive digestion than whole legumes, a topic our article on digesting legumes covers in detail. Adding spinach, rich in iron and folate, makes this a particularly worthwhile dish for regular vegetarian meals.

Why add a squeeze of lemon at the end?

Lentils and spinach are both rich in non-heme iron, a form of iron the body absorbs less efficiently than iron from animal sources, and whose absorption is further slowed by phytates naturally present in legumes. A landmark study by Hallberg, Brune and Rossander, published in 1989 in the American Journal of Clinical Nutrition, showed that vitamin C offsets this phytate-inhibiting effect on iron absorption in a dose-dependent way (see the study on Google Scholar). That study isn't about this dal specifically, but about the nutritional mechanism directly relevant to it: a squeeze of fresh lemon juice over the dish at serving time isn't just a bright finishing touch — it's a nutritionally meaningful step.

The recipe, step by step

1. Rinse 200 g (about 1 cup) of red lentils in cold water until it runs clear.
2. Cook the lentils in 600 ml (2.5 cups) of water with 1/2 tsp turmeric powder, covered, for 15 to 20 minutes, until they break down into a thick purée. Add more water if needed.
3. Add 150 g (about 5 cups loosely packed) of fresh baby spinach, roughly chopped, and cook for 3 to 4 minutes until wilted, then salt to taste.
4. Make the tadka: in a small pan, heat 2 tbsp ghee, add 1 tsp cumin seeds, 1/2 tsp mustard seeds, a pinch of asafoetida and, for milder Pitta profiles, 1 crumbled dried chili.
5. Pour the sizzling tadka over the dal right before serving, and finish with a squeeze of lemon juice.

Variations by dosha

Dosha	Suggested adjustment
Vata	A looser texture, generous with ghee, turmeric and fresh grated ginger in the tadka.
Pitta	Less chili, more fresh cilantro, a lighter hand with the lemon.
Kapha	A thicker texture, light on the ghee, black pepper and dried ginger to stimulate digestion.

Precautions

Spinach contains oxalates: people with a history of calcium oxalate kidney stones should moderate regular intake and check with their doctor. This legume-rich dish can cause bloating in sensitive digestion at first — pairing it consistently with the spiced tadka and chewing thoroughly helps limit that effect. This dish is not a treatment for a diagnosed iron deficiency, which requires medical advice and, often, targeted supplementation. The general safety framework is covered in our safety guide.
