Corn Soup
This corn soup recipe is the perfect balance of sweet corn, savory aromatics, and creamy texture. The partial blending technique creates a velvety base while keeping whole kernels for the perfect bite, all in under 30 minutes.
Equipment
- Large heavy-bottomed pot or Dutch oven - at least 5-quart capacity
- Immersion Blender - or countertop blender (optional)
- Sharp chef's knife
- Cutting board
- Wooden spoon or silicone spatula
- Ladle
- Measuring cups and spoons
- Vegetable peeler
Ingredients
- 4 cups sweet corn kernels - 580g, fresh or frozen
- 1 medium yellow onion - about 1 cup or 150g, diced
- 3 cloves garlic - minced
- 1 medium Yukon Gold potato - about 200g or 7 oz, peeled and diced into 1/2-inch cubes
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 4 cups low-sodium chicken broth - 950ml, or vegetable broth for a vegetarian version
- 1/2 teaspoon salt - plus more to taste
- 1/4 teaspoon black pepper
- 1/4 teaspoon smoked paprika
- 1/2 cup heavy cream or half-and-half - 120ml, optional, for a richer finish
- 2 tablespoons fresh chives or flat-leaf parsley - chopped, for garnish
- fresh lemon juice - a squeeze, to brighten the flavors at the end
For Serving (Optional)
- chili oil or hot sauce - for drizzling
- shredded cheddar cheese
- crusty bread or skillet cornbread - for serving on the side
Instructions
- Dice the onion, mince the garlic, peel and cube the potato, and cut fresh corn kernels off the cobs if using fresh corn.
- Melt butter and olive oil in a large pot over medium heat. Add the diced onion and cook for 5-7 minutes until soft and translucent. Add the minced garlic and cook for 1 minute until fragrant.
- Add the diced potato and sweet corn kernels to the pot. Stir in smoked paprika, salt, and pepper. Cook for 3-4 minutes, stirring occasionally.
- Pour in the chicken or vegetable broth and bring to a gentle boil. Reduce heat to medium-low and simmer uncovered for 15-18 minutes until the potato is fork-tender.
- Turn off the heat. Using an immersion blender, blend about half the soup directly in the pot for 30-45 seconds until creamy while still leaving whole corn kernels and potato pieces.
- Stir in heavy cream or half-and-half if using. Add a squeeze of fresh lemon juice. Taste and adjust salt and pepper as needed. Return to low heat for 2-3 minutes to warm through if necessary.
- Ladle the hot corn soup into bowls. Garnish with fresh chives or parsley and any desired toppings like chili oil, smoked paprika, or shredded cheddar. Serve immediately with crusty bread on the side.
Notes
- Don't Overcook: Corn loses its sweetness when simmered too long. Keep the simmer gentle and stick to the 15-18 minute window.
- Season in Layers: Add a little salt when sautéing aromatics, another pinch when adding vegetables, and adjust again at the end for deeper, more balanced flavor.
- Blend While Hot: Blend while the soup is hot but the heat is off for better control and safety.
- Fresh Corn Secret: If using fresh corn, scrape the cob with the back of your knife after cutting off the kernels to release the milky juice underneath.
- Adjust Sweetness: Corn sweetness varies. Add a tiny pinch of sugar if your corn is not very sweet, or an extra squeeze of lemon if it is too sweet.
- Make it Thicker: Blend more of the soup for a creamier texture. The potato also provides natural thickening through its starch.
- Vegan Version: Replace butter with olive oil or coconut oil, use vegetable broth, and swap heavy cream for full-fat coconut milk.
- Storage: Store in an airtight container in the refrigerator for up to 4 days. Freeze for up to 3 months. Reheat gently without boiling.
- Spicy Variation: Add 1-2 chipotle peppers in adobo sauce when adding the broth for a smoky-spicy depth.
- Cheesy Version: Stir in 1/2 cup of shredded sharp cheddar or Gruyere cheese at the end, off the heat, until melted and smooth.
