Recipes Using Red Lentils: Easy Coconut Lentil Curry

This red lentil coconut curry is a gently spiced, tomato-rich dish made with split red lentils, coconut milk, and everyday aromatics. It simmers into a creamy, spoonable meal that is delicious over rice or with flatbread, and the flexible seasoning makes it easy to adapt to your preferred heat level.

Ingredients

1 1/2 cups (285 g) dried split red lentils
1 tablespoon (15 ml) neutral oil, such as canola or sunflower oil
1 medium yellow onion, about 1 cup (150 g) finely diced
3 garlic cloves, about 1 tablespoon (15 g) finely chopped
1 tablespoon (15 g) peeled, finely grated fresh ginger
1 tablespoon (15 ml) tomato paste
1 teaspoon ground cumin
1 teaspoon ground coriander
1 teaspoon curry powder
1/2 teaspoon ground turmeric
1/4 teaspoon red pepper flakes, optional, or more to taste
1 can (14.5 ounces/410 g) diced tomatoes, with their juices
1 can (13.5 ounces/400 ml) full-fat coconut milk, well shaken
3 cups (710 ml) low-sodium vegetable broth
1 teaspoon fine salt, plus more to taste
1/4 teaspoon black pepper
2 cups (60 g) baby spinach, optional
1 tablespoon (15 ml) fresh lime juice, plus lime wedges for serving
1/4 cup (10 g) chopped fresh cilantro, optional

Instructions

Rinse the lentils. Put the red lentils in a fine-mesh sieve and rinse under cool running water, stirring them with your fingers until the water runs mostly clear. Pick out any small stones or debris, then drain well. Red lentils are split and usually need no soaking; rinsing removes loose starch and dust.
Soften the onion. Warm the oil in a large, heavy-bottomed saucepan or Dutch oven over medium heat. Add the diced onion and cook for 8 minutes, stirring now and then, until it is soft and translucent but not deeply browned. If the onion starts sticking, lower the heat and add a teaspoon of water.
Cook the aromatics and spices. Stir in the garlic and ginger and cook for 1 minute, stirring so they do not scorch. Add the tomato paste, cumin, coriander, curry powder, turmeric, and red pepper flakes if using. Stir continuously for about 30 seconds, just until fragrant; spices can turn bitter if left to toast unattended.
Add the liquids and lentils. Tip in the diced tomatoes and their juices, then stir for 2 minutes, scraping the bottom of the pan. Add the drained lentils, coconut milk, vegetable broth, salt, and black pepper. Stir thoroughly so lentils are not clumped together, then bring the mixture to a gentle boil over medium-high heat.
Simmer until tender. Reduce the heat to low and simmer uncovered for 22 minutes, stirring every few minutes and more frequently near the end. Keep the surface at a gentle bubble rather than a hard boil, which can make the bottom catch before the lentils soften. The lentils should break down easily when pressed against the side of the pan, and the curry should look thick and creamy.
Finish and adjust. If using spinach, stir it in during the final minute of cooking so it just wilts. Turn off the heat and mix in the lime juice. Taste and add more salt, pepper, or lime as needed. The curry thickens as it stands; stir in a small splash of hot water if you want it looser.
Serve. Spoon into warm bowls and finish with chopped cilantro and lime wedges, if desired. Put rice or flatbread on the table while the curry is hot so everyone can serve themselves.

Tips

Use split red lentils, not whole lentils. Split red lentils cook quickly and soften into the creamy texture this recipe is designed for. Whole red lentils or brown and green lentils hold their shape longer and need different cooking times, so they will not produce the same result if substituted cup for cup. Check the package because some bags labeled red lentils contain whole lentils.
Control thickness with liquid, not extra cooking. Lentils continue absorbing broth after the heat is off, so the curry may seem a little loose in the pot and become thicker in the bowl. For a stew-like consistency, let it stand for 5 minutes before serving; for a soupier curry, add hot broth or water a few tablespoons at a time.
Keep the spices fragrant, not burnt. The onion should soften before the garlic and spices go in. Stir the spices for only about 30 seconds, then add the tomatoes promptly. If the pan becomes dry or the spices darken rapidly, lower the heat and add the tomatoes rather than continuing to toast them.
Make an easy dairy-free swap. The recipe is dairy-free as written when made with vegetable broth. Full-fat coconut milk gives a rounded, creamy finish; light coconut milk can be used, but the curry will be less rich and may need a little less broth to reach the same thickness. For a non-coconut option, use unsweetened oat cream, noting that the flavor will be less tropical.

Serving Suggestions

Serve the curry over steamed basmati rice, brown rice, or another grain that can catch the sauce. A simple serving for four is about 3 cups (555 g) cooked rice alongside the pot of curry. Warm naan, roti, or another flatbread also works well for scooping. If you serve bread, a crisp salad of cucumber, tomato, and herbs adds coolness and crunch without competing with the spices.

For a more complete table, offer plain yogurt or a dairy-free yogurt alternative, extra lime wedges, and chopped cilantro separately. A small bowl of quick-pickled red onion or sliced cucumber gives each bite a sharp, fresh contrast. The curry is filling on its own, so sides can stay simple; avoid adding several heavily spiced dishes if you want its mild coconut and tomato flavors to stand out.

Variations

Make it hotter: Increase the red pepper flakes to 1/2 teaspoon, or add a finely chopped fresh chile with the garlic and ginger. Add a modest amount first, then taste near the end; chile heat can intensify as the curry sits. For a milder pot, leave out the flakes and serve sliced chile at the table.

Add vegetables: Stir in 1 cup (130 g) diced carrot with the onion and let it soften, or add 1 cup (150 g) diced zucchini during the last 10 minutes of simmering. For frozen peas, add 1 cup (135 g) during the final 3 minutes. Watery vegetables can loosen the curry, so allow it to simmer briefly uncovered if needed, stirring to prevent sticking.

Change the flavor direction: Use garam masala in place of curry powder for a warmer, more layered aroma, or add 1 teaspoon of mustard seeds to the oil and let them pop before adding onion. These are optional ways to personalize an Indian-inspired lentil curry, not requirements for a single regional or family version. If you do not have fresh ginger, use 1 teaspoon ground ginger; the result will taste less bright and fresh.

Make it more substantial: Add 1 cup (150 g) cooked chickpeas during the last 5 minutes, or top each bowl with roasted cauliflower. These additions change the texture and make the pot go further, but taste the finished curry again because extra ingredients may call for a little more salt or lime.

Storage and Reheating

Let leftovers cool briefly, then refrigerate them in a covered, shallow container within 2 hours of cooking. They keep for 3 to 4 days in the refrigerator. The lentils absorb liquid as they chill, so the curry will be thicker the next day; add a splash of broth or water when reheating to restore a saucy consistency.

Reheat a portion in a saucepan over medium-low heat, stirring often until it is steaming hot throughout. For food safety, leftovers should reach 165°F (74°C); check the center with a food thermometer if you are unsure. A microwave also works: cover loosely, heat in short intervals, and stir between intervals so the center warms evenly. Add fresh lime and herbs after reheating for a brighter finish.

To freeze, cool the curry and transfer it to freezer-safe containers, leaving a little room for expansion. Freeze for up to 3 months for best quality, then thaw overnight in the refrigerator before reheating. Coconut milk can look slightly separated after thawing, but stirring while it warms usually brings the sauce back together. Do not leave cooked curry at room temperature for more than 2 hours.

Frequently Asked Questions

Do red lentils need to be soaked before cooking?

No. Split red lentils cook quickly without soaking. Rinse them in a sieve to remove dust and loose starch, drain them, and add them directly to the pot. Soaking can make them break down even sooner, so it is unnecessary for this recipe and can make the timing less predictable.

Why are my red lentils still firm?

They may need more time, especially if they are older or the simmer was very gentle. Continue cooking at a low bubble and check every 2 to 3 minutes until the lentils crush easily. Acidic ingredients can sometimes slow softening, but this recipe adds the tomatoes before the lentils; if they remain firm, patience and a little extra simmering are usually the fix.

Can I use water instead of vegetable broth?

Yes. Use 3 cups (710 ml) water in place of the broth, then taste carefully at the end and add salt as needed. Broth contributes savory depth, so the water version may taste simpler. A little extra lime, cilantro, or a pinch of salt can help balance it without changing the cooking method.

Can I make this curry ahead?

Yes. Cook it fully, cool it promptly, and refrigerate it in a covered container for up to 3 to 4 days. It is convenient to make a day ahead because the seasonings have time to mingle, though the texture will thicken as the lentils absorb liquid. Reheat gently with a splash of broth or water, then adjust the lime and salt before serving.

Are red lentils the same as yellow lentils?

They are similar in how they cook when split, but the varieties can differ in flavor, color, and softness. Split red lentils often look orange when dry and turn golden as they cook; split yellow lentils may take longer depending on the variety. If using yellow lentils, follow the package guidance and allow extra simmering time until tender, adding liquid if the pot becomes too thick.
