A silky, blender-smooth sweet corn soup made with 5 ingredients in 15 minutes. No cream, no potato, no stock, and it’s naturally vegan.
Why This Sweet Corn Soup Works
Most sweet corn soup recipes lean on potato for body and cream for richness. This one skips both, as corn has enough natural starch to thicken itself once it’s fully blended. That’s the whole trick, and it’s why this takes 15 minutes instead of 45.
Here’s why you’ll love this recipe:
- 5 ingredients, all pantry staples besides the corn
- 15 minutes start to finish, including the topping
- Naturally vegan and gluten free with no substitutions needed
- Works with frozen corn year-round, no waiting for corn season
Ingredients
Corn kernels. Frozen corn is what I reach for most of the year. It’s picked and frozen at peak sweetness, so it often tastes better than out-of-season fresh corn. If it’s August and you have fresh ears, use them. Three large ears gives you about the right amount. Canned corn works in a pinch but rinse and drain it well, and cut the added salt back to ¾ teaspoon.
Water. Not a typo. With only five ingredients, corn is the flavor, and water lets it come through clean. Vegetable broth works if you want more savory depth, but it will mute the corn sweetness.
Garlic powder. Fresh garlic doesn’t work here. It stays raw and sharp in a soup that only simmers for a couple of minutes. Garlic powder dissolves completely and gives you the background savoriness without the bite.
Salt and pepper. Be generous with the salt. It’s what makes corn taste like corn instead of tasting flat.
How to Get It Silky Smooth
Texture is the thing that separates a good corn soup from a grainy one, and corn is genuinely hard to blend smooth. The kernel hulls are tough and they don’t break down easily.
A high speed blender does most of the work. Run it for a full 2 to 3 minutes, longer than feels necessary. The soup should look glossy and completely uniform, with no visible flecks.
If you’re using a regular blender, a food processor, or an immersion blender, blend as long as you can and then pour the soup through a fine mesh strainer before heating it. Press the solids with the back of a spoon. You’ll leave a small amount of hull behind and the texture will be noticeably better for it.
Jamie’s Tip
Tips for the Best Sweet Corn Soup
Blend before you heat. Blending cold corn with cold water pulls out more starch than blending cooked corn does, which is what gives this soup body without any thickener.
Taste after boiling. Heat mutes salt perception slightly. Season, bring to a boil, then taste and adjust.
Don’t skip the topping. The sauteed corn and parsley give you texture contrast against a completely smooth soup. Without it, the soup reads as one-note.
Variations
- Creamy version. Replace ½ cup of the water with whole milk, half and half, or coconut milk. Add it after blending, not before.
- Roasted corn. Toss the corn with oil and roast at 425F for 15 minutes before blending. It adds about 20 minutes but gives you a deeper, nuttier flavor.
- Spicy. Blend in half a jalapeno or add ¼ teaspoon cayenne.
- Chilled. This is good cold. Blend, chill, and serve as a summer starter. Thin with a splash of water since it thickens in the fridge.
- Toppings. Crispy bacon, chili crisp, a drizzle of olive oil, croutons, or crumbled cotija.
Storage
Refrigerate in an airtight container for up to 3 days. It thickens as it sits; thin with a splash of water when reheating.
Freeze for up to 1 month. Thaw overnight in the fridge and reheat gently on the stove, whisking to bring it back together if it separates.
Frequently Asked Questions
Yes. Three large ears of corn gives you roughly the 1⅔ cups the recipe calls for. Fresh corn is best in peak season, roughly July through September. Outside of that window, frozen corn is usually sweeter because it’s frozen right after picking.
Yes, but rinse and drain it thoroughly first to wash off the packing liquid, and reduce the salt to ¾ teaspoon since canned corn is already salted.
Corn kernel hulls are tough and don’t break down easily. If you don’t have a high speed blender, pour the blended soup through a fine mesh strainer before heating it. Press the solids with a spoon to get as much liquid through as possible.
It gives you the best texture with the least effort, but it isn’t required. A regular blender, food processor, or immersion blender will work if you blend longer and strain the soup afterward.
Yes. Replace about ½ cup of the water with milk, half and half, or heavy cream, and stir it in after blending rather than before.
Yes. As written it’s vegan, dairy free, and gluten free with no substitutions.
Yes. It keeps 3 days in the fridge and 1 month in the freezer. Make the sauteed corn topping fresh, since it loses its texture when stored.
Blending raw corn with cold water extracts more starch than blending cooked corn. That starch is what thickens the soup, which is why this recipe doesn’t need potato, flour, or cornstarch.

Easy 15 Minute Silky Sweet Corn Soup
Equipment
Ingredients
- 1⅔ cups corn kernels, or 3 large ears of corn
- 2 ¼ cups filtered water
- 1 teaspoon garlic powder
- 1 teaspoon salt
- ½ teaspoon pepper
Corn Topping
- ⅓ cup corn kernels
- ¼ cup chopped fresh parsley
- 1 teaspoon vegetable oil
Instructions
- Corn topping: Heat the vegetable oil in a small pan over medium heat. Saute the corn kernels until soft and lightly browned, 3 to 4 minutes. Stir in the chopped parsley, season with a pinch of salt and pepper. Set it aside.⅓ cup corn kernels, ¼ cup chopped fresh parsley, 1 teaspoon vegetable oil
- Blend the soup: Add the corn kernels, water, garlic powder, salt, and pepper to a high-speed blender. Blend for 2 to 3 minutes, until completely smooth and glossy with no visible flecks. If using a regular blender, food processor, or immersion blender, blend as long as you can, then pour the soup through a fine mesh strainer, pressing the solids with a spoon.1⅔ cups corn kernels, 2 ¼ cups filtered water, 1 teaspoon garlic powder, 1 teaspoon salt, ½ teaspoon pepper
- Heat through: Transfer the soup to a pot and bring to a gentle boil over medium heat, stirring so it doesn't scorch, about 2 to 3 minutes. Taste and adjust salt.
- Serve: Ladle into bowls and top with the sauteed corn and parsley.
Notes
- Corn: Frozen, fresh, or canned all work. Use 3 large ears if using fresh. If using canned, rinse and drain well and reduce salt to ¾ teaspoon.
- For the smoothest texture: Blend for a full 2 to 3 minutes in a high speed blender. If using a regular blender, food processor, or immersion blender, strain the soup through a fine mesh sieve before heating.
- Make it creamy: Substitute ½ cup of the water with milk, half and half, or coconut milk. Stir it in after blending.
- Make it savory: Substitute vegetable broth for the water. It adds depth but slightly mutes the corn sweetness.
- Storage: Refrigerate up to 3 days or freeze up to 1 month. The soup thickens as it sits, so thin with a splash of water when reheating.

I had some frozen corn to use up and came across this recipe. It is just divine and so simple. My partner loves bacon, so I garnished the soup with bacon and onion, along with the extra corn. We will make it again!
We are big soup fans and are really pleased to have come across this recipe. Whilst I am a huge corn fan, I prefer it to be blended rather than in pieces, and so this soup was perfect for me. We followed the recipe as written, except I added 1/4 cup of cream at the end and cut back on the water slightly. It is luscious!
I need to incorporate some milk in my diet and was wondering if I could use half of the filtered water the recipe calls for and the other half with 2% milk?
Absolutely you can substitute with milk!
This soup has the most incredible texture! We served with some garlic bread and it made a really lovely meal. I look forward to taking the leftovers to work tomorrow for lunch!
Thanks Deanne! That’s a wonderful idea pairing this with garlic bread. I love the texture of this too! So glad you liked it!
Love a comforting bowl of soup, and this was so delicious. The perfect, smooth texture – so satisfying. We topped with some crispy bacon!
Thanks Amber! That’s a great idea topping the corn soup with bacon!
Wow this was easy to make and tasted so good! I’m making this again!
