• 18 gGarlic (6 cloves, finely grated or minced)
• 10 gFresh rosemary (about 4 sprigs; leaves chopped (reserve sprigs for tray))
• 10 gFine sea salt (1 3/4 tsp, divided)
• 2 gBlack pepper (1 tsp, freshly ground)
• 800 gPotatoes (Yukon Gold or other waxy potatoes; cut into 3 cm chunks)

• 2 tspLemon zest (finely grated)
• 2 sprigsFresh rosemary sprigs (for roasting on the tray)

Instructions

1. 1

   Bloom the saffron for maximum aroma: crush the saffron threads to a powder, then pour 30 ml hot water over it. Cover and let stand 10 minutes. Meanwhile, pat the chicken thighs very dry with paper towels so the skin roasts crisp rather than steaming.

2. 2

   Make the marinade in a bowl: whisk together olive oil, lemon juice, grated garlic, chopped rosemary leaves, 8 g salt (about 1 1/4 tsp), black pepper, and the bloomed saffron with all its liquid. Add chicken and turn to coat thoroughly, rubbing under and over the skin.

3. 3

   Marinate for flavor and tenderness: cover and refrigerate 45 minutes (or up to 12 hours). For even roasting, remove the chicken from the refrigerator 20 minutes before cooking. During this time, preheat the oven to 220°C / 425°F with a rack in the middle.

4. 4

   Prepare the tray: on a large rimmed baking sheet (about 33×46 cm), spread sliced onion and potato chunks. Sprinkle with the remaining 2 g salt (about 1/2 tsp) and toss with 1 tablespoon of the marinade scraped from the bowl. Add 60 ml water to the tray to encourage juicy drippings.

5. 5

   Arrange and roast: place chicken thighs skin-side up on top of the potatoes, spacing them apart. Tuck 2 rosemary sprigs among the potatoes. Roast at 220°C / 425°F for 25 minutes, then rotate the tray front-to-back for even browning.

6. 6

   Finish roasting until safe and crisp: reduce oven to 200°C / 400°F and roast 20–30 minutes more, until the thickest thigh reaches 74°C / 165°F and the skin is deeply golden. If needed, broil/grill on high for 2–3 minutes, watching closely to avoid burning.

7. 7

   Rest and glaze with pan juices: transfer chicken to a plate and rest 10 minutes. Toss potatoes and onions in the saffron-tinged drippings on the tray. Sprinkle lemon zest over everything, then spoon a little pan sauce over the chicken to serve while hot.
