Tips
White miso is milder than other varieties; do not boil vigorously after adding to preserve delicate flavor.
For vegetarian version, substitute vegetable broth as noted and ensure miso paste contains no fish-based ingredients.
Blend in batches if immersion blender struggles with volume.
Good to Know
Refrigerate leftovers in an airtight container for 3 to 5 days.
Prepare soup up to step 6 (before blending) and refrigerate up to 24 hours. Blend and serve when ready.
Serve hot or chilled. Garnish with remaining green onions, sesame seeds, and red pepper flakes.
Common Mistakes
Do not boil soup vigorously after miso paste is added to avoid destroying delicate fermented flavors.
Do not skip blending to avoid chalky, uneven texture from whole sweet potato pieces.
