Pan-Seared Duck Breast with Herb Butter

Why This Works for Intermittent Fasting

Duck breast is one of the most satisfying proteins for an eating window — it's naturally high in fat (especially in the skin), rich in protein, and deeply flavourful without needing heavy sauces. The high fat-to-protein ratio keeps you satiated for hours after eating, making it ideal for OMAD or a shorter eating window. Duck is also rich in iron and B vitamins, nutrients that matter for anyone doing longer fasts.

Ingredients

For the duck:

• 2 duck breasts (skin-on, approximately 180–200g each)
• Sea salt and freshly ground black pepper
• 1 teaspoon fresh thyme leaves (or ½ tsp dried)

For the herb butter:

• 50g (3 tablespoons) unsalted butter, softened
• 1 clove garlic, minced
• 1 tablespoon fresh parsley, finely chopped
• 1 teaspoon fresh thyme, finely chopped
• ½ teaspoon fresh rosemary, finely chopped
• Pinch of sea salt
• Squeeze of lemon juice

To serve (optional):

• Handful of watercress or rocket
• Drizzle of olive oil

Instructions

1. Score the skin. Using a sharp knife, score the duck skin in a crosshatch pattern — cuts about 1cm apart, going through the fat but not into the meat. This allows the fat to render properly and the skin to become crispy.

2. Season generously. Pat the duck breasts dry with paper towel. Season both sides generously with sea salt and black pepper, and rub the thyme leaves into the scored skin.

3. Start in a cold pan. Place the duck breasts skin-side down in a cold, dry skillet (no oil needed — duck fat is sufficient). Turn heat to medium. Let the fat render slowly for 12–15 minutes, pouring off excess fat as it accumulates. The skin should become deep golden and crispy.

4. Make the herb butter. While the duck cooks, mix together the softened butter, garlic, parsley, thyme, rosemary, salt, and lemon juice until well combined. Set aside at room temperature.

5. Flip and finish. Flip the duck breasts and cook flesh-side down for 3–4 minutes for medium (slightly pink in the centre) or 5–6 minutes for more well-done. Internal temperature guide: 57°C/135°F for medium-rare, 63°C/145°F for medium.

6. Rest before cutting. Remove from pan and rest on a warm plate for 5 minutes. This is essential — cutting immediately causes the juices to run out.

7. Serve. Slice each breast diagonally into 4–5 pieces. Top immediately with a generous portion of herb butter (it will melt over the hot slices). Serve alongside watercress or rocket with a drizzle of olive oil if desired.

Nutrition Per Serving

Note: Values are approximate and will vary based on exact duck breast size and how much fat is rendered off during cooking.

Fasting Compatibility

This recipe works well for any eating window, from 16:8 to OMAD. The high fat content from the duck skin and herb butter provides sustained satiety — most people find they don't feel hungry again for 5–6 hours after this meal. It's fully carnivore-compatible (omit the garnish greens) and keto-friendly with essentially zero net carbohydrates.
