A few quick notes
1. Roast from frozen
Toss the frozen corn with oil and seasonings, then roast it directly without thawing.
2. Save some corn
Reserve one cup of roasted corn before simmering the rest with onion and water for the soup base.
3. Strain after blending
Pass the pureed soup through a fine mesh sieve for a smoother texture before returning it to the pot.

How to make it
0 of 6 steps completeMake room for Japanese Corn Soup (corn potage)
Review ingredients in your pantry before anything is added. Meal plans use your household size; grocery-only additions use the servings selected above.
The last little job
Add kernels back
Stir the reserved corn into the finished soup and garnish with parsley and a drizzle of cream if desired.
A little more help as you go
Cool slightly for blending
If using a regular blender, let the soup cool slightly first to help prevent hot liquid splashing.
Stir the creamy soup
Keep stirring during the final low simmer so the milk and cream soup does not stick to the pot bottom.
A few questions you might have
Should I thaw frozen corn?
No. Cook it directly from frozen for the roasting stage with oil and seasonings.
Why reserve some corn?
Add the reserved roasted kernels back at serving so the smooth soup also has some whole corn texture.
Does the soup need straining?
The directions strain the blended soup through a fine mesh sieve for a smoother texture before adding dairy.
Can I serve it cold?
Yes. The serving directions allow the soup hot or chilled, finished with parsley and a cream drizzle.
Can stock replace water?
Vegetable or chicken stock works, though water keeps the corn's sweetness clear.
Any more cooking tips?
Cook frozen corn without thawing it. Roasting the corn first adds sweetness and flavor; reserve one cup for serving if you like. Vegetable or chicken stock makes a richer soup, while water lets the corn's own sweetness stand out. Strain the soup after blending for a silky texture.
Storage & reheating safety
For cooked, perishable leftovers, refrigerate within 2 hours (1 hour above 90°F), using shallow containers for prompt cooling. Keep the refrigerator at 40°F or below, use refrigerated leftovers within 3–4 days, and reheat hot leftovers to 165°F, checked with a food thermometer. Follow any shorter package limit.
