Creamy Sunchoke Soup with Brown Butter & Crispy Sage

Sunchokes — also called Jerusalem artichokes — are one of those underrated vegetables that deserve far more attention than they get. Knobby, earthy, and nutty-sweet, they purée into one of the silkiest soups imaginable. This recipe takes them all the way: a slow sauté to build depth, a smooth blitz until velvety, and a finish of brown butter and crispy sage that turns a humble bowl into something genuinely special.

Ingredients

• 1½ lbs sunchokes, scrubbed and roughly chopped (no need to peel)
• 1 medium yellow onion, diced
• 3 cloves garlic, smashed
• 3 tbsp extra-virgin olive oil, divided
• 4 cups low-sodium chicken or vegetable stock
• 1 cup whole milk or heavy cream
• Kosher salt and freshly ground black pepper
• 4 tbsp unsalted butter
• 10–12 fresh sage leaves
• Flaky sea salt, to finish

Instructions

1. Sweat the aromatics: Warm 2 tablespoons of olive oil in a large heavy-bottomed pot over medium heat. Add the onion and a pinch of salt. Cook, stirring occasionally, until the onion is soft and translucent, about 8 minutes. Add the garlic and cook 1 minute more.
2. Add the sunchokes: Stir in the chopped sunchokes along with another pinch of salt. Cook for 5 minutes, letting them pick up a little color and heat through.
3. Simmer: Pour in the stock and bring to a boil. Reduce heat to a gentle simmer, cover, and cook until the sunchokes are completely tender when pierced with a fork, about 20–25 minutes.
4. Blend: Working in batches (or using an immersion blender), blend the soup until completely smooth. Return to the pot and stir in the milk or cream. Season generously with salt and pepper. Keep warm over low heat.
5. Make the brown butter and crispy sage: In a small skillet over medium heat, melt the butter. Continue cooking, swirling the pan, until the butter turns golden brown and smells nutty — about 3–4 minutes. Add the sage leaves and fry for 30–45 seconds until crisp. Remove from heat immediately.
6. Serve: Ladle the soup into warm bowls. Drizzle brown butter generously over each portion and top with 2–3 crispy sage leaves. Finish with a pinch of flaky sea salt.

Tips

• No need to peel sunchokes — the skins are thin and add flavor and nutrients. Just scrub them well under cold water.
• Watch the brown butter closely — it goes from golden to burnt in seconds. Pull it off the heat the moment it smells like toasted hazelnuts.
• The soup thickens as it sits. If reheating, add a splash of stock or water to loosen it back to the right consistency.
• For an extra-silky result, strain the blended soup through a fine-mesh sieve before finishing with the cream.

Variations

• Add a smoky note: Stir in ½ teaspoon of smoked paprika with the garlic for a subtle warmth that pairs beautifully with the nutty sunchoke.
• Make it richer: Swap the milk for heavy cream and add a tablespoon of crème fraîche stirred in just before serving.
• Add a crunch topping: Toast a handful of hazelnuts or pumpkin seeds and scatter over the soup alongside the crispy sage.
• Make it vegan: Use vegetable stock, substitute the butter with a good-quality vegan butter or olive oil, and use full-fat oat milk in place of dairy cream.

Pairs Well With

• A thick slice of sourdough or crusty farm bread for dunking
• Grilled pork tenderloin or roasted chicken thighs — the soup is rich enough to anchor a full meal
• A simple arugula salad with lemon vinaigrette to cut through the richness
• Grass-fed beef short ribs as a hearty winter starter before the main course
