One-Pot Roasted Sunchoke and Crispy Rosemary Dip
A silky, earthy dip celebrating sunchokes—the subtle, nutty root vegetable also called Jerusalem artichokes. Roasted until caramelized and pureed smooth, they're enriched with cream and butter, then crowned with crispy rosemary leaves fried in olive oil until fragrant and golden. French-inspired with a rustic edge, this elegant dip works as an appetizer for entertaining or a luxe snack with crusty bread, vegetables, or crackers.

Steps
Before you start
- Preheat your oven to 400°F (200°C)
- Scrub sunchokes under cold running water to remove all soil; use a soft brush or vegetable brush if available
- Have cream and butter at room temperature for smoother blending
Prepare and season sunchokes
- Pat the scrubbed sunchokes dry with a clean kitchen towel.
- In a large bowl, toss the sunchoke pieces with 3 tbsp (45 ml) extra-virgin olive oil, ¾ tsp (4 g) kosher salt, and ¼ tsp black pepper until evenly coated.
- Spread them in a single layer on a large baking sheet (17×12 inches / 43×30 cm), cut-side down where possible.
- Scatter the halved garlic cloves and thyme sprigs among them.

Tip: Pat the sunchokes very dry so they caramelize rather than steam in the oven.
Roast until golden and tenderOven 400°F / 205°C
- Roast the sunchokes in a preheated 400°F (200°C) oven for 30–35 minutes, stirring halfway through (about 15–17 minutes in), until the edges are deep golden-brown and a fork pierces the flesh with no resistance.
- The sunchokes should smell sweet and slightly caramelized.
- Remove the pan from the oven and let cool for 5–7 minutes.
- Discard the thyme sprigs and squeeze the roasted garlic flesh out of its skin into a small bowl; discard the skin.

Ready when: Sunchokes are deep golden-brown at the edges and fork-tender inside; they smell sweet and nutty
Tip: Stir halfway through so all pieces caramelize evenly and don't scorch on one side.
Fry rosemary until crispy
- While the sunchokes roast, heat 2 tbsp (30 ml) extra-virgin olive oil in a small skillet (8 inches / 20 cm) over medium-high heat.
- When the oil shimmers, add the rosemary leaves (remove any stems) and fry for 1–2 minutes, stirring gently, until they are fragrant, crispy, and bright green (some may deepen slightly in color).
- Use a wooden spoon to move them constantly so they crisp without burning.
- Pour the rosemary and its oil into a small dish lined with paper towels to drain and cool.
- Reserve for garnish.

Ready when: Rosemary leaves are fragrant, crispy, bright green, and oil smells herbaceous
Tip: Watch the heat carefully—rosemary can turn from crispy to burnt very quickly. Keep the burner at medium-high, not high.
Purée sunchokes and garlic
- Transfer the roasted sunchokes and roasted garlic to a food processor (or high-powered blender).
- Add 4 tbsp (57 g) unsalted butter and ½ cup (120 ml) heavy cream.
- Blend on high speed for 1–2 minutes until completely smooth and creamy, scraping down the sides as needed.
- If you want an extra-silky texture, pass the purée through a fine-mesh sieve into a serving bowl.

Ready when: Mixture is completely smooth with no visible lumps; it should be pourable but thick enough to hold a slight mound
Tip: Blend in two stages if your processor is small—blend sunchokes and garlic first, then add butter and cream and pulse until smooth to avoid overheating.
Season and finish
- Taste the dip.
- Stir in 1 tbsp (15 ml) fresh lemon juice and the optional white miso paste (if using, it adds subtle umami depth without a detectable flavor).
- Season to taste with additional salt and pepper.
- Transfer the dip to a serving bowl and create a shallow well in the center with the back of a spoon.
- Drizzle with a little of the reserved rosemary oil, then scatter the crispy rosemary leaves and optional fleur de sel over the top.

Ready when: Dip is well-seasoned (taste a small spoonful), and rosemary garnish is evenly distributed
Tip: Add miso paste only if you have it—it's optional but elevates the savory depth. Lemon juice brightens the earthy sunchokes.
Good to know
Tips
- Sunchokes can vary in water content depending on variety and season. If your blended dip seems too thick, add cream 1 tbsp at a time; if too thin, blend in another 1 tbsp softened butter.
- Look for firm, smooth sunchokes without wrinkled or soft spots. Store them in a paper bag in the refrigerator for up to 2 weeks. Scrub them just before use—sunchokes have thin, bumpy skin that traps soil.
- For a French bistro presentation, serve this dip warm with crusty bread, thinly sliced radishes, endive spears, or blanched baby carrots on the side.
- The earthiness of sunchokes pairs beautifully with white wines (Sauvignon Blanc, Albariño) or dry ciders.
Make ahead
The dip base (sunchokes, garlic, butter, and cream) can be made up to 2 days ahead. Store it in an airtight container in the refrigerator. Reheat gently in a small saucepan over medium-low heat, stirring constantly, until warm (do not boil). Make the crispy rosemary garnish no more than 4 hours ahead—store it in an airtight container at room temperature. Top the dip with crispy rosemary and oil just before serving.
Storage & reheating
Store leftover dip in an airtight container in the refrigerator for up to 3 days. Reheat gently in a small saucepan over medium-low heat. Do not microwave, as the dip may separate. Crispy rosemary garnish should be stored separately and added just before serving. The dip does not freeze well because of the cream content.
Substitutions
- sunchokes (Jerusalem artichokes) → parsnips or a 50/50 blend of parsnips and celery root. Parsnips are sweeter and less nutty; reduce roasting time by 5 minutes if using only parsnips as they cook faster.
- heavy cream → crème fraîche, Greek yogurt, or sour cream. Use the same amount. Yogurt and sour cream will add tanginess; stir in 1 tsp honey if using sour cream to balance the tang.
- fresh rosemary sprigs → crispy sage leaves, fried parsley, or toasted breadcrumbs mixed with Parmesan cheese. Sage is earthier and more peppery; breadcrumbs add textural contrast if you prefer crunch over the herbaceous note.
- white miso paste → ½ tsp Dijon mustard or anchovy paste. Mustard adds sharpness; anchovy paste adds savory umami. Both are optional but enhance depth.
