Whole Roasted Chicken with Herbs and Butter

Why This Works for Intermittent Fasting

A whole roasted chicken is one of the most efficient proteins you can put in your eating window. A single serving delivers over 40g of complete protein with a satisfying fat ratio from the crispy skin and herb butter — keeping you full through the entire fasting window that follows. The combination of protein and fat with minimal carbohydrates supports a smooth transition back into fat-burning mode once the eating window closes.

Ingredients

• 1 whole chicken (1.5–1.8 kg)
• 80g unsalted butter, softened (about 6 tbsp)
• 4 cloves garlic, minced
• 2 tsp fresh thyme leaves (or 1 tsp dried)
• 2 tsp fresh rosemary, finely chopped (or 1 tsp dried)
• 1 tsp fresh sage, finely chopped
• Zest of half a lemon (optional)
• 1½ tsp sea salt
• ½ tsp black pepper
• 2 tbsp olive oil or ghee
• 4 garlic cloves, unpeeled (for the cavity)
• A few sprigs of fresh rosemary and thyme (for the cavity)

Instructions

1. Bring the chicken to room temperature. Remove from the fridge 30 minutes before cooking. This ensures even cooking throughout.

2. Preheat oven to 200°C (390°F). Use the fan/convection setting if available — it produces crispier skin.

3. Make the herb butter. Combine softened butter with minced garlic, thyme, rosemary, sage, lemon zest (if using), salt, and pepper. Mix thoroughly with a fork until well combined.

4. Prepare the chicken. Pat dry all over with paper towels. Dry skin is the key to crispiness — do not skip this step.

5. Apply the herb butter. Carefully loosen the skin over the breast and thigh areas by sliding your fingers under the skin without tearing it. Press about two-thirds of the herb butter directly onto the flesh under the skin. Rub the remaining butter all over the outside of the chicken.

6. Season the cavity. Stuff the cavity loosely with the unpeeled garlic cloves and herb sprigs. Season with a pinch of sea salt inside.

7. Tie the legs. Truss the legs together with kitchen twine to help the chicken cook evenly.

8. Roast. Place the chicken breast-side up in a roasting tin. Drizzle with olive oil or ghee. Roast for 20 minutes per 500g plus an extra 20 minutes — for a 1.6 kg bird, approximately 80 minutes total.

9. Check for doneness. Pierce the thickest part of the thigh — juices should run completely clear. The internal temperature at the thigh bone should reach 75°C (165°F).

10. Rest the chicken. Remove from the oven and rest, uncovered, for 10–15 minutes before carving. This allows the juices to redistribute throughout the meat.

11. Serve. Carve and serve with the roasting juices spooned over the top. The roasted garlic cloves from the cavity can be squeezed out as a soft, caramelised condiment.

Nutrition Per Serving

Based on 1 serving (skin-on, bone-in) of a 1.6 kg chicken with herb butter, divided into 4 portions.

Fasting Compatibility

This recipe fits any intermittent fasting protocol, including 16:8, 18:6, OMAD, and 5:2. The high protein content (42g per serving) supports muscle preservation during the fasting window, while the fat from butter and skin extends satiety through a long fast. For OMAD practitioners, pair with a green salad dressed with olive oil for a complete one-meal plate.
