EQUIPMENT NEEDED
- Cast iron skillet or heavy-bottomed pan

- Meat thermometer
- Paper towels
- Cutting board
INGREDIENTS
- 2 duck breast halves (6-8 oz each), skin-on, room temperature
- 2 tablespoons unsalted butter
- 4 cloves garlic, minced
- 1 teaspoon sea salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon dried thyme (or 1 fresh sprig)
- 1/4 teaspoon smoked paprika (optional)
METHOD
- Pat duck breasts completely dry with paper towels.
- Score skin in a crosshatch pattern (diagonal lines 1/2 inch apart) – DO NOT cut into meat.
- Season generously with salt and pepper on both sides.
- Place breasts skin-side down in a COLD cast iron skillet.
- Turn heat to medium-low and cook for 10-12 minutes until skin is golden brown and crispy.
- Pour off excess fat every few minutes (save it!).
- Flip breasts and cook meat-side down for 2 minutes.
- Transfer skillet to preheated 375°F (190°C) oven for 5-7 minutes for medium-rare.
- Remove when internal temperature reaches 135°F (57°C).
- Rest on cutting board for 5 minutes.
- Meanwhile, make garlic butter sauce: melt butter in the same pan, add garlic, cook until fragrant (30 seconds).
- Slice duck against the grain and drizzle with garlic butter.
CRUCIAL TIPS
- Start with a COLD pan – this is essential for fat rendering.
- Score skin only, not meat.
- Pour off fat regularly while cooking.
- Don’t skip the resting period.
- Save rendered duck fat for future cooking.
STORAGE & REHEATING
- Store in airtight container up to 3 days.
- Reheat in 350°F oven for 10-15 minutes.
- Best served medium-rare.
COMMON MISTAKES TO AVOID
- Starting with a hot pan.
- Cutting into meat when scoring.
- Overcooking (duck will become tough).
- Not rendering enough fat.
- Moving duck during initial cooking.
VARIATIONS
- Add fresh herbs like rosemary or sage to butter.
- Finish with sugar-free berry sauce.
- Use rendered fat for roasting vegetables.
- Add crushed peppercorns for au poivre style.
Remember: The key to perfect duck breast is patience during the rendering process. Don’t rush it – good things come to those who wait!
