Version v1 older · History (2)

Serves 3

Ingredients

• 500 g small waxy potatoes (Drillinge)
• 2 leeks
• 30 ml olive oil
• salt
• black pepper
• 1 g dried thyme (or a few fresh sprigs)
• 600 g chicken thighs (4 bone-in skin-on)
• 50 ml vegetable broth
• 15 g dijon mustard
• 100 g crème fraîche
• 0.5 lemon

Steps

1. Heat the oven to 220°C.
2. Halve small waxy potatoes (500 g). Halve leeks (2) lengthwise and cut into 4 cm logs (use the white and light-green parts; wash well — they hide grit between the layers). Toss the potatoes and leeks with olive oil (15 ml), salt, black pepper, and dried thyme (1 g). Spread on a sheet pan.
3. Pat chicken thighs (600 g) dry. Rub with olive oil (15 ml), salt, and black pepper. Place skin-up on the pan, nestled among the veg.
4. Roast ⏲ 35 minutes until the chicken skin is crisp and the potatoes are tender. Internal temp 75 °C at the thickest part of the thigh.
5. Transfer the chicken and veg to plates. Tilt the pan, spoon off most of the fat (leave about 15 ml).
6. Place the pan over medium heat on the stove. Add vegetable broth (50 ml), scrape up the brown bits. Whisk in dijon mustard (15 g) and crème fraîche (100 g). Simmer for ⏲ 1 minutes until slightly thickened. Add a squeeze of lemon (0.5). Taste for salt.
7. Serve the sauce on the side — Cozy gets plain chicken plus potatoes.
