1.Scrub the Jerusalem artichokes well under running water to remove any grit. Roughly chop into 1-inch pieces, no need to peel.2.Trim the dark green tops and root ends from the leeks. Slice the white and light green parts in half lengthwise, then thinly slice into half-moons.3.Peel and dice the potato into 1-inch cubes.TIPJerusalem artichokes discolor quickly after cutting. Drop them into a bowl of water with a squeeze of lemon if prepping ahead. - saute · ~10 min
Sweat the leeks and garlic.
1.Heat olive oil in a Dutch oven over medium-low heat.2.Add sliced leeks and a pinch of salt. Cook gently, stirring occasionally, until softened but not browned, about 8 minutes.3.Add minced garlic and cook for 1 minute until fragrant.TIPKeep the heat gentle — leeks should sweat and soften, not fry. Browning them will add bitterness to the finished soup. - simmer · ~20 min

If it feels too thick, add a splash of hot water to loosen. - serve · ~1 min

What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Scrub Jerusalem artichokes well but leave the thin skin on for extra earthy flavor and nutrients.
- 2Add a teaspoon of lemon juice to the soaking water to prevent the sunchokes from browning during prep.
- 3Cook the leeks on medium-low heat until completely soft and translucent — browning will add bitterness.
- 4Pierce the sunchokes and potato with a knife to test doneness; they should offer no resistance before blending.
- 5Blend for a full 2–3 minutes with an immersion blender for a velvety, luscious texture without cream.
- 6This soup thickens as it cools; stir in a little hot water or broth when reheating to restore consistency.
- 7Make ahead and refrigerate for up to 3 days — the flavor deepens overnight as the leeks and herbs meld.
