Note

Storage: This soup can be prepared 1 day ahead. Cover and refrigerate. When ready to serve, return to saucepan and reheat gently, thinning with additional broth if necessary.

Variation: For a richer texture, you can stir in a splash of non-dairy cream or coconut milk after blending.

Tip: Ensure the soup is cooled slightly before blending to prevent splattering and to avoid damaging your blender. Use a tamper if available to help push ingredients down.

Ingredient Note: Russet potatoes provide a creamy starchiness that helps thicken the soup naturally. You can substitute with Yukon Gold potatoes for a slightly different flavor profile.
