Why This Recipe Works
🍳 What You'll Need for This Recipe
Essential tools to make this recipe perfectly
This sweet corn soup recipe stands out for several key reasons:
- Fresh Corn Flavor: Using fresh corn kernels (or frozen if fresh isn’t available) ensures the most vibrant and authentic corn flavor.
- Creamy Texture: The addition of a cornstarch slurry creates a beautiful, velvety smooth texture without relying on heavy cream, making it lighter and healthier.
- Balanced Sweetness: A touch of sugar enhances the natural sweetness of the corn, creating a perfectly balanced flavor profile.
- Aromatic Base: Sautéing aromatics like onion and garlic builds a flavorful base that complements the corn beautifully.
- Customizable: This recipe is a blank canvas! Add protein like chicken or shrimp, incorporate other vegetables like carrots or celery, or spice it up with a pinch of chili flakes.
Ingredients
- 4 ears of fresh corn, kernels removed (approximately 4 cups) or 4 cups frozen corn kernels
- 1 tablespoon olive oil or vegetable oil
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 4 cups vegetable broth or chicken broth
- 1 teaspoon sugar (optional, adjust to taste based on corn sweetness)
- 1/2 teaspoon salt, or to taste
- 1/4 teaspoon black pepper, or to taste
- 2 tablespoons cornstarch
- 1/4 cup cold water
- Optional Garnishes: Chopped fresh chives, green onions, cilantro, a swirl of cream, croutons, or a sprinkle of red pepper flakes.

Instructions
- Prepare the Corn: If using fresh corn, shuck the corn and remove the kernels. You can do this by standing the corn cob upright and running a sharp knife down the sides. If using frozen corn, thaw it slightly.
- Sauté Aromatics: Heat the olive oil in a large pot or Dutch oven over medium heat. Add the chopped onion and cook until softened and translucent, about 5 minutes. Add the minced garlic and cook for another minute, until fragrant. Be careful not to burn the garlic.
- Add Corn and Broth: Add the corn kernels and broth to the pot. Bring to a simmer, then reduce the heat and cook for about 15-20 minutes, or until the corn is tender.
- Blend the Soup (Optional): For a smoother soup, use an immersion blender to blend the soup directly in the pot. Alternatively, carefully transfer the soup to a regular blender in batches and blend until smooth. Be cautious when blending hot liquids. If you prefer a chunkier soup, skip this step.
- Make the Cornstarch Slurry: In a small bowl, whisk together the cornstarch and cold water until smooth. This will prevent lumps from forming when added to the hot soup.
- Thicken the Soup: Pour the cornstarch slurry into the simmering soup, stirring constantly. Continue to simmer for 2-3 minutes, or until the soup has thickened to your desired consistency.
- Season and Adjust: Stir in the sugar (if using), salt, and pepper. Taste and adjust the seasoning as needed. You may want to add more salt or sugar depending on the sweetness of the corn and your personal preference.
- Serve: Ladle the soup into bowls and garnish with your favorite toppings, such as chopped chives, green onions, cilantro, a swirl of cream, or a sprinkle of red pepper flakes. Serve hot.
Tips for Success
- Use the Best Corn: The quality of your corn will directly impact the flavor of the soup. Choose fresh, sweet corn whenever possible. If using frozen, opt for a high-quality brand.
- Don’t Overcook the Garlic: Burnt garlic can make the soup bitter. Cook it until just fragrant, about 1 minute.
- Taste and Adjust: Seasoning is crucial! Taste the soup frequently and adjust the salt, pepper, and sugar to your liking.
- Control the Thickness: The amount of cornstarch can be adjusted to achieve your desired soup consistency. For a thinner soup, use less cornstarch. For a thicker soup, use more.
- Strain for Extra Smoothness: If you want an incredibly smooth soup, strain it through a fine-mesh sieve after blending.
- Add a Touch of Spice: A pinch of red pepper flakes or a dash of hot sauce can add a subtle kick to the soup.
Storage Instructions
To Store: Allow the soup to cool completely before transferring it to an airtight container. Store in the refrigerator for up to 3-4 days.
To Reheat: Reheat the soup gently in a saucepan over medium heat, stirring occasionally, until heated through. You can also reheat it in the microwave. Add a splash of broth or water if the soup has thickened too much during storage.
To Freeze: Sweet corn soup freezes well. Allow the soup to cool completely before transferring it to freezer-safe containers or freezer bags. Leave some headspace in the containers, as the soup will expand when frozen. Freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating.

FAQ
Q: Can I use canned corn?
A: While fresh or frozen corn is recommended for the best flavor, you can use canned corn in a pinch. Drain and rinse the canned corn before adding it to the soup. Keep in mind that canned corn may have a slightly different texture and flavor than fresh or frozen corn.
Q: Can I make this soup vegetarian?
A: Yes! Simply use vegetable broth instead of chicken broth.
Q: Can I add protein to this soup?
A: Absolutely! Cooked chicken, shrimp, or tofu are all great additions. Add them to the soup during the last few minutes of cooking to heat them through.
Q: Can I make this soup vegan?
A: Yes! Use vegetable broth, ensure that your sugar is vegan-friendly (some sugar is processed using bone char), and omit any dairy garnishes.
Q: Why is my soup not thickening?
A: Make sure you’re using cold water to make the cornstarch slurry. Hot water can cause the cornstarch to clump. Also, be sure to simmer the soup for a few minutes after adding the slurry to allow the cornstarch to activate and thicken the soup.
