Dal Indian Curry: Red Lentil Dal with Tadka Recipe

Dal is a comforting Indian lentil curry, and this version pairs tender red lentils with tomato, warming spices, and a fragrant cumin-garlic tadka. It is served as a main or side with rice or flatbread, and its simple ingredients make a flavorful, adaptable meal without a long soak.

Ingredients

1 cup (200 g) dried red split lentils (masoor dal), picked over and rinsed
4 cups (950 ml) water, plus up to 1 cup (240 ml) hot water to adjust consistency
1 medium yellow onion, finely chopped, about 1 cup (150 g)
1 medium ripe tomato, chopped, about 1 cup (150 g), or ¾ cup (180 g) canned diced tomato
1 tablespoon (15 ml) neutral oil, such as sunflower or canola oil
1 tablespoon (15 ml) ghee, or use another 1 tablespoon (15 ml) oil
2 teaspoons (10 g) finely grated fresh ginger
3 garlic cloves, finely chopped, about 1 tablespoon (9 g)
½ teaspoon (1 g) ground turmeric
1 teaspoon (6 g) fine salt, plus more to taste
1 teaspoon (2 g) ground coriander
½ teaspoon (1 g) garam masala
1 small dried red chile, or ¼ teaspoon (0.5 g) red pepper flakes, optional
1 teaspoon (2 g) cumin seeds
¼ teaspoon (0.5 g) black mustard seeds, optional
Pinch of asafoetida, also called hing, optional
6 fresh curry leaves, optional
1 tablespoon (15 ml) fresh lemon juice
¼ cup (10 g) chopped fresh cilantro leaves and tender stems

Instructions

Prepare the ingredients. Finely chop the onion and tomato, grate the ginger, and chop the garlic. Rinse the lentils in a fine-mesh sieve under cool water, swishing them gently until the water runs mostly clear. Let them drain while you measure the spices. This prep takes about 15 minutes, including chopping and measuring.
Soften the onion. Warm the neutral oil in a medium heavy-bottomed saucepan or Dutch oven over medium heat. Add the onion and cook for 5 to 7 minutes, stirring often, until it is soft and translucent with a little golden color at the edges. Keep the heat moderate; deeply browned onion can make this mild dal taste heavier and may scorch as the lentils simmer.
Cook the aromatics and tomato. Stir in the ginger and garlic and cook for 30 seconds, just until fragrant. Add the chopped tomato, ground coriander, turmeric, and garam masala. Cook for 2 to 3 minutes, stirring and pressing the tomato with the spoon, until it softens and begins to look saucy. If the mixture sticks, add a tablespoon of water rather than turning the heat very high.
Simmer the lentils. Add the rinsed lentils, 4 cups (950 ml) water, and salt. Stir, bring the pot to a boil, then lower the heat to maintain a gentle simmer. Cook uncovered for about 22 minutes, stirring every few minutes and more frequently toward the end. The lentils are ready when they have broken down into a soft, creamy mixture; if they are still firm, add a splash of hot water and simmer for a few more minutes. Red lentils vary slightly by age and brand, so use tenderness rather than the clock alone as your final guide.
Make the tadka. When the lentils are tender, heat the ghee in a small skillet over medium heat. Add the cumin seeds and optional mustard seeds. When the cumin smells nutty and the seeds begin to pop, usually within 30 to 60 seconds, add the dried chile or pepper flakes, asafoetida, and curry leaves if using. Stand back when adding curry leaves because any water on them can make the fat splutter. Stir for about 20 seconds, then take the skillet off the heat before the garlic or spices can burn. If you prefer a milder dal, leave out the chile.
Finish and serve. Pour the hot spiced ghee and seeds into the lentil pot, scraping in the flavorful bits. Stir and simmer together for 2 minutes so the tadka seasons the dal. Stir in the lemon juice and cilantro, then taste and add more salt or lemon as needed. The finished dal should be creamy but pourable. Add hot water a little at a time if it thickened too much; simmer briefly if it seems thinner than you like.

Tips

Rinse, but do not soak. Red split lentils cook quickly and do not need soaking. Rinsing removes loose dust and starch so you can judge the texture more easily. If using whole lentils or a different variety, expect a longer cooking time and follow the package guidance.
Control the heat gently. A lively boil can make lentils stick to the bottom before they soften. Keep the pot at a quiet simmer, stir regularly, and use a heavy-bottomed saucepan if you have one. If you notice sticking, move the pot off the burner briefly and loosen the bottom with a wooden spoon.
Make the tadka aromatic, not burnt. Cumin should smell toasted, not acrid. Take the pan off the heat as soon as the seeds are fragrant and add the spices that burn quickly only at the end. Asafoetida can be difficult to find; omit it if necessary. It adds a distinctive savory, onion-like note, but the dal is still good without it.
Adjust the texture at the end. Dal thickens as it cools, so aim for a slightly looser consistency in the pot than you want in the bowl. Add hot water gradually and taste again for salt and lemon after thinning. Cold water can briefly slow the simmer and make it harder to judge the final texture.

Serving Suggestions

Serve the dal hot in bowls with steamed basmati rice, jeera rice, or another plain rice that can soak up the sauce. Roti, chapati, or naan are useful for scooping, and a combination of rice and bread makes a generous meal. Add a simple side such as sliced cucumber, tomato, and red onion with lemon, or a lightly dressed green salad for freshness and crunch.

For a fuller spread, set out plain yogurt or a cucumber raita, lime wedges, and extra cilantro. Keep the dal as the saucy centerpiece and serve the sides separately so everyone can season a portion to taste. If serving it as one dish among several, this recipe makes four side portions; with rice and a vegetable side, it can serve four as a main. A spoonful of ghee on top is optional, not necessary, because the tadka already gives the lentils a rich, fragrant finish.

Variations

Make it hotter: Add another dried chile to the tadka or increase the red pepper flakes in small increments. You can also pass chile flakes at the table, which lets diners choose their own heat level without changing the whole pot.

Use another lentil: Yellow split mung dal cooks to a similar soft texture, though its flavor is milder. Toor dal (split pigeon peas) is a classic choice in many Indian preparations, but it generally takes longer to soften and may need more water; simmer until tender rather than following the red lentil timing. Whole brown or green lentils hold their shape and produce a less creamy curry, so they are not a direct, equal-time swap.

Add greens: Stir in 2 cups (60 g) baby spinach during the final 2 minutes, just until wilted. Chopped kale can be added earlier and simmered until tender. Greens contribute their own flavor and can make the dal a little thicker, so add a little hot water if needed.

Make it richer or dairy-free: Replace the ghee with oil for a fully dairy-free version. For a creamier variation, stir in ¼ cup (60 ml) coconut milk near the end; this gives the dal a sweeter, coconut-forward flavor that is less traditional for this simple tadka style. A pinch of extra salt and lemon can balance that added richness.

Storage and Reheating

Cool leftovers promptly and refrigerate them in a covered container within 2 hours of cooking. The dal keeps for 3 to 4 days in the refrigerator. It thickens considerably as it sits, so store it as it is rather than adding lots of water in advance. For longer storage, freeze portions in freezer-safe containers for up to 3 months for best quality, leaving a little room for expansion. Thaw overnight in the refrigerator when possible.

Reheat a portion in a saucepan over medium-low heat, stirring often and adding water a tablespoon or two at a time until it is creamy again. Heat leftovers to 165°F (74°C), checking with a food thermometer; the USDA FSIS safe reheating temperature for leftovers is 165°F (74°C). You can also microwave it in a covered, microwave-safe bowl, stirring halfway through and checking the temperature in more than one spot. If the dal has separated slightly after freezing, stir it well as it warms. Add fresh lemon or cilantro after reheating to brighten the flavor.

Frequently Asked Questions

Do red lentils need to be soaked for dal?
No. Red split lentils cook quickly, and rinsing them is enough for this recipe. Soaking is not required and can make them soften faster than expected. If you soak them anyway, reduce the water slightly and start checking for tenderness earlier.

Why is my dal too thick or too thin?
Thickness depends on the lentils, how vigorously they simmer, and how long they stand after cooking. If the dal is too thick, stir in hot water a little at a time until it pours easily. If it is too thin, simmer it uncovered for a few extra minutes, stirring so the bottom does not catch. It will thicken further as it cools.

Can I make this dal without ghee?
Yes. Use the same quantity of neutral oil for the tadka. Ghee gives the spices a rounded, buttery aroma, while oil keeps the recipe dairy-free and tastes lighter. Avoid using an oil with a strong flavor unless you specifically want it in the finished dish.

Can I make the dal ahead?
Yes. Cook it fully, cool it promptly, and refrigerate it for up to 3 to 4 days. The flavors meld as it rests, but the texture becomes thicker. Reheat it with a little water and finish with fresh cilantro or a squeeze of lemon. For the brightest tadka aroma, you can make the spiced ghee just before serving and stir it in then.

Is dal the same as curry?
Dal refers to dried pulses such as lentils and also to dishes made from them. In English, “dal curry” or “dal Indian curry” often describes a seasoned lentil stew like this one. Recipes differ by region and household: the lentil, spices, consistency, and whether a tadka is poured over the top can all vary.
