Chicken Thighs with Roasted Root Vegetables

Why This Works for Intermittent Fasting

Bone-in, skin-on chicken thighs are one of the best proteins to centre an eating window meal around — high in fat, rich in protein, deeply satisfying, and genuinely hard to overeat. The roasted vegetables here are low-starch root and bulb vegetables: turnip, celeriac, and fennel — they caramelise beautifully in the oven, bring natural sweetness without spiking blood sugar, and provide fibre that slows digestion and extends satiety. This meal is equally suited to 16:8, 18:6, and OMAD protocols.

Ingredients

For the chicken:

• 4 bone-in, skin-on chicken thighs (approx. 900g / 2 lbs total)
• 2 tbsp olive oil
• 1 tsp sea salt
• 1 tsp smoked paprika
• ½ tsp garlic powder
• ½ tsp dried thyme
• ½ tsp black pepper

For the roasted vegetables:

• 1 small celeriac (approx. 400g), peeled and cut into 3cm cubes
• 2 medium turnips, peeled and cut into 3cm cubes
• 1 large fennel bulb, fronds removed, cut into wedges
• 4 cloves garlic, skin on
• 2 tbsp olive oil
• 1 tsp sea salt
• ½ tsp black pepper
• 1 tbsp fresh thyme leaves (or 1 tsp dried)

To serve:

• Fresh parsley, roughly chopped
• Lemon wedges
• Optional: 1 tbsp ghee to finish the chicken

Instructions

1. Preheat your oven to 220°C / 425°F (fan: 200°C / 400°F). Line a large roasting tray or use a heavy-based oven dish.

2. Prepare the vegetables. Peel and cube the celeriac and turnips. Cut the fennel bulb into thick wedges, keeping the core intact so the layers hold together. Add all vegetables and garlic cloves to the roasting tray. Drizzle with olive oil, season with salt, pepper, and thyme, and toss until everything is coated. Spread into a single layer.

3. Season the chicken. Pat the chicken thighs dry with a paper towel — this is the key to crispy skin. Mix the smoked paprika, garlic powder, thyme, salt, and pepper. Rub the spice mixture over the chicken, making sure to get some under the skin where possible. Drizzle with olive oil.

4. Roast the vegetables first. Place the vegetable tray in the oven for 15 minutes before adding the chicken. This gives the denser root vegetables a head start.

5. Add the chicken. After 15 minutes, push the vegetables to the edges of the tray and nestle the chicken thighs skin-side up in the centre. Roast for a further 30–35 minutes until the chicken skin is deep golden and crispy and the internal temperature reads 74°C / 165°F.

6. Rest and serve. Remove from the oven. If using, add a small knob of ghee to each chicken thigh and let it melt over the surface. Rest for 5 minutes before serving. Scatter fresh parsley over the vegetables and serve with lemon wedges.

Fasting Compatibility

This meal is ideal for any time-restricted eating protocol. The high protein content supports muscle preservation during fasting periods, and the combination of fat from the chicken skin and fibre from the root vegetables produces lasting satiety — making it an excellent final meal before a 16-to-20-hour fasting window. It also works well as a first meal to break a fast, eaten slowly over 20–30 minutes.
