Jerusalem artichoke confit with chestnut honey, rosemary and Pecorino — Topinambur Confit, Miele di Castagno, Rosmarino e Pecorino (Italian Jerusalem Artichoke Confit)

Jerusalem artichoke has a naturally earthy, nutty sweetness that becomes much deeper when cooked slowly in fat and then finished at high heat. The technique here is deliberately closer to confit than standard roasting.

Chestnut honey brings bitterness as well as sweetness, rosemary reinforces the earthy profile, and Pecorino adds salinity and depth. The finished dish should feel concentrated and savory, not sugary.

Ingredients

For the Jerusalem Artichokes

2 lb Jerusalem artichokes (900 g)
1 cup extra virgin olive oil (240 ml)
4 garlic cloves, lightly crushed
3 sprigs rosemary
4 sprigs thyme
1 tsp kosher salt (6 g)
½ tsp freshly ground black pepper (1 g)

For the Chestnut Honey Glaze

2 tbsp chestnut honey (40 g)
2 tbsp vegetable stock (30 ml)
1 tbsp apple cider vinegar (15 ml)
1 tbsp unsalted butter (14 g)
1 small rosemary sprig
Pinch of sea salt

For the Pecorino

2½ oz aged Pecorino, finely grated or shaved (70 g)

For the Rosemary Crumb

½ cup fresh breadcrumbs (35 g)
1 tbsp extra virgin olive oil (15 ml)
1 tsp finely chopped rosemary
1 small garlic clove, finely grated
Pinch of salt

For Finishing

1 tsp lemon zest
Extra virgin olive oil
Freshly ground black pepper
Flaky sea salt

Preparation

1. Confit the Jerusalem Artichokes

Preheat the oven to 300°F (150°C). Scrub Jerusalem artichokes thoroughly without peeling. Keep small ones whole and halve only large pieces. Place in a roasting dish with olive oil, garlic, rosemary, thyme, salt and pepper. Cover tightly and cook for 40 to 50 minutes until tender but still holding shape.

2. Cool Briefly

Remove from the oil, drain well and rest for about 10 minutes so the exterior dries slightly. Strain and reserve the aromatic oil.

3. Prepare the Chestnut Honey Glaze

Warm chestnut honey, stock, vinegar and rosemary gently for 2 to 3 minutes. Remove rosemary, whisk in butter and season. The glaze should be bittersweet and acidic rather than dessert like.

4. Crisp the Jerusalem Artichokes

Increase the oven to 450°F (230°C). Lightly press larger pieces to crack the surface, brush with reserved confit oil and roast for 10 to 15 minutes until deeply golden. Brush with honey glaze only during the final 2 to 3 minutes.

5. Prepare the Rosemary Crumb

Toast breadcrumbs in olive oil until golden, then add garlic and chopped rosemary for the final 30 seconds and season lightly.

6. Final Assembly

Arrange Jerusalem artichokes directly on the plate in a loose irregular composition. Spoon a small amount of glaze over selected pieces, add rosemary crumb, finish with Pecorino, lemon zest, olive oil, black pepper and flaky sea salt.

Professional Technique

Confit cooking surrounds the Jerusalem artichokes with fat at low temperature, allowing the interior to soften without drying. The second high temperature stage creates the crust.

Separating tenderization from crisping is what produces a soft center and deeply roasted exterior without collapse. A short rest between stages also improves the final crust.

Chef Tips

Keep smaller Jerusalem artichokes whole whenever possible.
Do not peel unnecessarily.
Chestnut honey is useful because it has a natural bitter edge.
Use the glaze sparingly.
Do not discard the aromatic confit oil.

Common Mistakes

Cooking too hot during the confit stage.
Overcooking before crisping.
Adding honey before high heat.
Using too much glaze.
Peeling completely.
Skipping the high heat finish.

Wine Pairing

Verdicchio dei Castelli di Jesi Classico Superiore works very well because its acidity and mineral character balance olive oil, Pecorino and honey.

Vermentino di Gallura DOCG is another excellent choice. For red wine, choose a lighter Chianti Classico with fresh acidity.

Storage & Reheating

The Jerusalem artichokes can be confit up to 2 days ahead and refrigerated in a little strained confit oil. Bring close to room temperature before final roasting.

The chestnut honey glaze keeps for 4 days. Keep rosemary crumb dry and separate.
