Ingredients

(per duck leg)

• 1 duck leg (thigh + drumstick)
• 1 tsp kosher salt
• Freshly ground black pepper
• Pinch thyme or rosemary
• Optional: 1 garlic clove, lightly smashed
• Optional: small sliver of lemon peel
• Optional: 1 tsp duck fat (for bag)

Equipment

• Sous vide circulator
• Vacuum sealer or freezer-grade zip-top bags
• Ice bath
• Paper towels
• Air fryer (preferred for reheat) or skillet

Method

1. Season

Season the duck leg evenly with salt and black pepper. Add a pinch of thyme or rosemary. Include garlic or lemon peel only if desired; restraint is key.

2. Bag

Place 1–2 legs per bag. Add a small spoonful of duck fat if using. Remove as much air as possible and ensure legs are not folded or pressed awkwardly.

3. Sous-Vide Cook

Cook at 75 °C (167 °F) for 24 hours, undisturbed.

4. Chill

Transfer sealed bags directly to an ice bath for 15 minutes, until fully cold.

5. Dry and Flash Freeze

Remove legs from bags and pat very dry. Place uncovered on a tray and freeze until the surface is solid (1–2 hours).

6. Package for Storage

Once surface-frozen, transfer legs to: - Zip-top bags - Vacuum bags - Or rigid containers

Freeze for up to 6 months with no quality loss.

Reheating & Crisping

Air Fryer (Best — Default Event Method)

From frozen: - 400°F for 15–20 minutes - Skin side up - No oil required

From sous vide (reheated at ~140°F / 60°C): - Pat very dry before cooking - Optional: light brush of duck fat for extra blistering - 400°F for 6–10 minutes, skin side up

Results: - Shatteringly crisp skin - Melting, tender interior - Zero flipping - Minimal attention

This is the method to use 99% of the time.

Pan-Seared (Second Best)

From thawed or SV-warmed legs: - Medium–high heat - Skin side down until glassy and crisp - Flip for ~30 seconds

Excellent flavor, but less convenient and less even than air fryer.

Sous-Vide Reheat (Non-Crispy)

For slicing into salads or composed plates: - 140–150 °F for ~45 minutes - Do not crisp - Serve warm, tender, and richly seasoned

Doneness Cues

• Meat pulls easily from the bone
• Interior is silky and gelatin-rich
• Skin crisps fully without drying the meat
• No chalkiness or stringiness

Notes

• The sous vide approach doesn't seem to make it as soft as I'm hoping for — try the non-sous vice approach.
• 75 °C / 24 h is the sweet spot: higher temps lose structure; lower temps lack full confit texture.
• Flash freezing before long-term storage prevents legs from sticking together.
• Do not oversalt—confit concentrates seasoning over time.
• Air fryer skin texture rivals restaurant salamanders.
