What Does Mulligatawny Soup Taste Like?

Mulligatawny is a warmly spiced, hearty soup that bridges Indian and British cooking, typically made with lentils, vegetables, apples, and often chicken or coconut milk. Its flavor is a balanced symphony of earthy turmeric, fragrant curry, sweet apple, and a gentle heat from pepper or chili, finished with a silky, slightly tangy broth. The name comes from the Tamil phrase milagu thanni (pepper water), reflecting its origins as a spicy lentil broth that British colonists adapted into a richer, more substantial soup.

Ingredients

2 tablespoons (30 ml) vegetable oil or ghee
1 large yellow onion, diced (about 1½ cups / 200 g)
2 celery stalks, diced (about 1 cup / 120 g)
2 carrots, peeled and diced (about 1 cup / 130 g)
1 tart apple (such as Granny Smith), peeled, cored, and diced
3 garlic cloves, minced
1 tablespoon (15 g) fresh ginger, grated
2 tablespoons (15 g) curry powder (mild or medium)
1 teaspoon (2 g) ground turmeric
½ teaspoon (1 g) ground cumin
¼ teaspoon (0.5 g) cayenne pepper (adjust to taste)
1 cup (200 g) red lentils, rinsed and picked over
6 cups (1.4 L) chicken or vegetable broth
1 can (13.5 oz / 400 ml) full-fat coconut milk
1 tablespoon (15 ml) fresh lemon juice
1 teaspoon (6 g) salt, plus more to taste
Freshly ground black pepper, to taste
Optional: 1½ cups (210 g) shredded cooked chicken (rotisserie or leftover)
For garnish: fresh cilantro leaves, plain yogurt, or extra lemon wedges

Instructions

Heat the oil or ghee in a large Dutch oven or heavy pot over medium heat. Add the onion, celery, carrots, and apple. Cook, stirring occasionally, until the vegetables soften, about 8–10 minutes.
Add the garlic, ginger, curry powder, turmeric, cumin, and cayenne. Stir constantly for 1 minute until fragrant. This blooms the spices and deepens their flavor.
Stir in the rinsed red lentils, then pour in the broth. Scrape any browned bits from the bottom of the pot. Bring to a boil, then reduce heat to low, cover, and simmer for 20 minutes, stirring occasionally to prevent sticking.
If using chicken, add it now. Pour in the coconut milk and lemon juice. Stir well and simmer uncovered for another 10–15 minutes, until the lentils are fully soft and the soup has thickened slightly.
Season with salt and black pepper. Taste and adjust—you may want more lemon for brightness or more cayenne for heat.
For a smoother texture, blend about half the soup with an immersion blender (or in a regular blender in batches, being careful with hot liquid). Leave the rest chunky for body.
Ladle into bowls and garnish with cilantro, a swirl of yogurt, or a lemon wedge. Serve hot.

Tips

Spice level: Curry powders vary wildly in heat. Start with 2 tablespoons of a mild blend; if you prefer more kick, add extra cayenne at the end rather than the beginning.
Lentil swap: Red lentils break down quickly and give the soup its velvety texture. If you only have brown or green lentils, increase the simmer time by 10–15 minutes and expect a chunkier result.
Don’t skip the apple: It adds a subtle sweetness that balances the earthy spices and sharpens the overall flavor. A firm, tart apple holds up best; avoid mealy varieties.
Blend with care: If using a countertop blender, let the soup cool slightly and fill it only halfway. Hold the lid down with a towel and vent the steam to avoid splatters.

Serving Suggestions

Serve mulligatawny as a main course with warm naan, basmati rice, or crusty bread for dipping. A spoonful of plain yogurt or a drizzle of coconut milk on top adds creaminess. For a lighter meal, pair it with a simple green salad dressed with lemon vinaigrette. If you like, offer extra lemon wedges and chopped cilantro at the table so everyone can adjust brightness and freshness to taste.

Variations

Vegetarian/Vegan: Use vegetable broth and omit the chicken; the coconut milk already makes it rich. Add chickpeas or extra vegetables like zucchini or cauliflower for more substance.
Traditional British style: Add 1 cup (150 g) cooked rice instead of chicken, and finish with a spoonful of mango chutney stirred in just before serving.
Spicier version: Increase the cayenne to ½ teaspoon or add a finely chopped fresh green chili (like serrano) with the garlic and ginger.
Smoky twist: Use smoked paprika (1 teaspoon) in place of the cumin, and consider adding a pinch of smoked salt at the end.
Protein boost: Stir in a cup of cooked chickpeas or white beans along with the coconut milk for extra fiber and protein.

Storage and Reheating

Let the soup cool to room temperature within 2 hours of cooking, then transfer to an airtight container. Refrigerate for up to 4 days. The flavors actually deepen overnight, making it a great make-ahead meal. To freeze, portion into freezer-safe containers or zip-top bags, leaving ½ inch of headroom; it will keep for up to 3 months. Thaw overnight in the refrigerator before reheating. Warm gently on the stovetop over medium-low heat, stirring often, or in the microwave in 1-minute intervals. If the soup has thickened too much after refrigeration, add a splash of broth or water to loosen it. Reheat leftovers to a safe minimum internal temperature of 165°F (74°C) before serving.

Frequently Asked Questions

Is mulligatawny soup supposed to be spicy? Traditionally it has a gentle warmth rather than intense heat. The cayenne and curry powder provide a mild tingle; you can easily adjust the amount to suit your tolerance. If you want authentic heat, add more black pepper or a fresh chili, since the name literally means “pepper water.�

Can I make mulligatawny without coconut milk? Yes. Replace it with an equal amount of extra broth or a splash of heavy cream for a lighter, less rich soup. The coconut milk adds sweetness and body, so the final texture will be thinner without it—you may want to blend more of the soup to compensate.

What does the apple do in this soup? The apple provides a subtle fruity sweetness that balances the earthy spices and adds a slight tang. It also helps thicken the soup as it cooks down. If you skip it, add a teaspoon of sugar or a little more carrot to make up for the lost sweetness.

Can I use yellow or green lentils instead of red? Yes, but the texture will be different. Brown or green lentils hold their shape and take longer to soften, so increase the simmering time to 30–35 minutes and expect a chunkier, less creamy soup. Yellow lentils (split moong dal) work well and cook almost as quickly as red.

Is mulligatawny gluten-free? As written, yes—just ensure your curry powder and broth are certified gluten-free, since some commercial blends contain wheat flour. Serve with rice or gluten-free bread to keep the meal entirely gluten-free.

Can I freeze mulligatawny with coconut milk? Absolutely. Coconut milk can separate slightly when frozen and thawed, but that’s normal—just whisk the soup well while reheating. The texture may become a bit grainier, but the flavor remains excellent. For best results, freeze without the yogurt garnish and add it fresh after reheating.
