Ingredients
Method
- Heat oil in a large saucepan over medium-high heat. Add 1¾ cups radishes and onion; cook, stirring frequently, until onions begin to brown and radishes are translucent, about 5 minutes. Stir in potato, milk, salt, and pepper. Bring to a boil, then reduce heat to a simmer. Cover and cook, stirring occasionally, until the potato is tender, about 5 minutes more.
- Puree the mixture in batches using a blender or an immersion blender until smooth, taking care when handling the hot liquid.
- Slice the remaining ¼ cup radishes into matchsticks. Serve the soup garnished with 1 tablespoon sour cream, radish matchsticks, and radish greens or parsley.

Notes
Potato Texture:
I have learned that blending the soup just until smooth is key: if you over-blend the Yukon Gold potato, the starch can turn the texture a bit heavy or gummy.
Ingredient Variation: While I usually reach for standard red radishes, I have discovered that using Daikon radishes creates a much milder flavor if you want something less peppery.
Heat Management: I always keep a close eye on the pot once the milk is added, making sure it stays at a gentle simmer to prevent the dairy from curdling or scorching.
Zero Waste Tip: I strongly suggest saving the best-looking radish leaves for the garnish: they have a wonderful mustard-like zip that really wakes up the creamy base.
Reheating Advice: When I warm up leftovers the next day, I add a tiny splash of water or extra milk to loosen things up since the potato tends to thicken the soup as it sits in the fridge.
Garnishing Insight:
Do not skip the fresh radish matchsticks at the end: I love how that raw, crunchy texture breaks up the silkiness of the pureed soup.
