Indian Corn Soup with Sweet Corn and Vegetables

Indian corn soup is a lightly thickened sweet-corn soup, often served as part of Indian-Chinese cuisine in India. Sweet corn, finely chopped vegetables, ginger, pepper and a little soy sauce make a savory, gently sweet bowl that is easy to adjust for heat and texture.

Ingredients

2 cups sweet corn kernels (300 g), fresh or thawed frozen, divided
1 tablespoon neutral oil (15 ml), such as sunflower or canola oil
1 tablespoon finely chopped fresh ginger (10 g)
2 garlic cloves, finely chopped (about 6 g)
¼ cup finely chopped carrot (35 g)
¼ cup finely chopped green beans (30 g)
½ cup finely shredded green cabbage (35 g)
4 cups low-sodium vegetable broth or water (960 ml)
1 tablespoon soy sauce (15 ml), plus more to taste
¼ teaspoon ground white pepper (about 0.5 g), or black pepper
2 tablespoons cornstarch (16 g)
3 tablespoons cold water (45 ml), for the cornstarch slurry
½ teaspoon fine salt (about 3 g), plus more to taste; use less if your broth is salted
1 teaspoon rice vinegar (5 ml), optional
1 small green chili, finely chopped (about 5 g), optional
2 tablespoons sliced scallion greens (about 10 g), for serving

Instructions

Prepare the corn and vegetables. If using fresh corn, remove the kernels from the cobs; if using frozen corn, thaw it and drain away excess water. Set aside 1 cup (150 g) of the kernels. Put the remaining 1 cup (150 g) in a blender with ½ cup (120 ml) of the broth or water and blend until mostly smooth. A few small pieces are fine. Chop the ginger, garlic, carrot and beans, and shred the cabbage so the vegetables cook quickly and evenly.
Heat the oil for 1 minute. Place a medium saucepan or soup pot over medium heat and add the oil. When it shimmers, add the ginger, garlic and optional green chili. Stir for about 2 minutes, just until fragrant. Keep the heat moderate; browned garlic can make the broth taste bitter.
Cook the vegetables for 4 minutes. Add the carrot and green beans and stir for 2 minutes. Add the cabbage and continue stirring for another 2 minutes. The vegetables should soften slightly but still have some color and bite, since they will cook further in the broth.
Simmer the soup for 10 minutes. Pour in the remaining broth or water, the blended corn, and the reserved whole kernels. Stir in the soy sauce, white pepper and salt. Bring the soup to a gentle boil, then lower the heat and simmer uncovered for 10 minutes, stirring occasionally. Avoid a hard boil, which can make the vegetables overly soft and cause the soup to reduce more than intended.
Thicken it for 3 minutes. In a small bowl, stir the cornstarch into the cold water until no dry lumps remain. Give the slurry another stir, then pour it slowly into the simmering soup while stirring continuously. Simmer for about 3 minutes, until the broth looks glossy and lightly thickened. If it becomes thicker than you like, stir in a splash of hot water or broth.
Season and finish for 2 minutes. Taste the soup and adjust the salt, soy sauce or pepper. Stir in the optional rice vinegar for a gentle tang, then let the soup bubble gently for 2 minutes. Ladle into bowls and scatter scallion greens over the top. Serve hot.

Tips

Choose the corn texture you like. Blending half the kernels gives the soup body while the remaining kernels stay whole. For a smoother bowl, blend more of the corn; for a chunkier soup, blend less. If your blender is small, blend the corn in batches and take care with hot liquid—this recipe blends the corn before it is heated.
Cut the vegetables small. Pieces around ⅛ to ¼ inch (3–6 mm) cook in the short simmer and are easy to eat with a spoon. Larger pieces need more time and can leave the corn overcooked before the vegetables are tender.
Keep the slurry lump-free. Always combine cornstarch with cold water before it goes into the hot pot. Stir while adding it, and let the soup simmer briefly afterward so the starch thickens evenly. Adding dry cornstarch straight to the soup can leave floury lumps.
Adjust salt at the end. Soy sauce and broth both contribute salt, and their levels vary. Start with the listed amount, then taste after the soup thickens. If you only have regular soy sauce or salted broth, begin with less added salt.

Serving Suggestions

Serve the soup as a first course or as a light meal with toasted bread, dinner rolls or a side of steamed rice. For an Indian-Chinese-style spread, pair it with vegetable fried rice, noodles, chili paneer or a simple stir-fried vegetable dish. The soup is mild enough to sit alongside bolder, spicy foods, while its corn sweetness works well with savory, crisp sides.

Set out extra sliced scallions, black pepper, soy sauce and chopped green chili so everyone can finish a bowl to taste. A small splash of vinegar at the table can brighten a serving, but add it sparingly; too much will make the corn taste less sweet. If serving the soup as part of a larger meal, pour modest portions into small bowls and keep the garnish separate until serving.

Variations

Make it vegetarian or vegan: The recipe is already vegetarian when made with vegetable broth. Choose a vegan broth and check that the soy sauce suits your needs; no dairy is required for the soup to thicken. For a richer, rounder finish, stir in ¼ cup (60 ml) of unsweetened plant milk after thickening, understanding that it will soften the peppery, clear-broth character.

Make it hotter: Include the green chili, add a pinch of red chili flakes with the ginger, or serve chili sauce on the side. Fresh green chilies vary in heat, so start with a small amount if you are unsure. For a milder soup, leave the chili out and use black pepper sparingly instead of white pepper.

Use other vegetables: Finely diced bell pepper, celery or a few sliced mushrooms can replace some of the carrot, beans or cabbage. Keep the total amount of vegetables close to the listed amount so the broth remains balanced. Add vegetables that need more cooking time with the carrot and beans; stir in tender greens near the end so they do not lose their color.

Make it without a blender: Mash about half of the corn with a fork or potato masher, or leave all the kernels whole for a thinner broth. Blending creates the soup’s characteristic smooth body, but it is not essential. If you prefer a richer soup without blending, add another teaspoon of cornstarch mixed with cold water, a little at a time, until it reaches the thickness you want.

Storage and Reheating

Cool the soup promptly and refrigerate it within 2 hours of cooking. Store it in a covered, airtight container for 3–4 days. The cornstarch may settle or the soup may become thicker as it chills, so stir it well before reheating and add a little water or broth if needed.

Reheat only the portion you plan to eat in a saucepan over medium heat, stirring often until it is steaming throughout and reaches 165°F (74°C), the USDA FSIS safe temperature for reheated leftovers. You can also reheat a serving in the microwave in a microwave-safe bowl, stirring midway through and checking that the center is thoroughly hot. Avoid repeated cooling and reheating of the whole batch.

For longer storage, freeze the soup in airtight, freezer-safe containers for up to 2 months for best quality. Leave a little room for expansion, thaw it overnight in the refrigerator, and reheat as described above. The vegetables may soften and the thickened broth can separate slightly after freezing; stirring while reheating usually brings it back together, though the texture may be less crisp than when freshly made.

Frequently Asked Questions

Can I use canned sweet corn?
Yes. Drain and rinse canned corn before measuring, then use the same quantity by volume. Canned corn can be softer and saltier than fresh or frozen corn, so taste the broth before adding the full amount of salt. Reserve some kernels whole and blend the rest as directed.

Can I make Indian corn soup without cornstarch?
Yes. The blended corn gives the broth some body even without a slurry, so you can omit the cornstarch and cold water for a thinner soup. Another option is to blend a larger portion of the cooked corn and vegetables. If you use a different thickener, follow its package guidance, since the amount and cooking method may differ.

What can I use instead of vegetable broth?
Water works well and lets the sweet corn flavor stand out, though the soup will taste less savory. You can also use low-sodium chicken broth if you do not need the soup to be vegetarian. Taste before adding salt, because broths and soy sauces vary considerably in seasoning.

Is Indian corn soup the same as sweet corn soup?
The names are often used for similar soups, especially the Indo-Chinese-style version made with corn, broth, vegetables and seasonings such as ginger, pepper and soy sauce. Recipes vary by restaurant and household: some are thinner, some are more heavily thickened, and some include egg or additional vegetables. This version uses no egg and has a lightly thickened texture.

How can I make the soup thicker or thinner?
For a thicker soup, blend more corn or add a little extra cornstarch slurry, allowing it to simmer for a couple of minutes before deciding whether to add more. For a thinner soup, stir in hot broth or water a little at a time. Make adjustments gradually because the soup thickens as it stands and cools.
