Ingredients
- •4 duck breasts (8–10 oz each)
- •2 tsp kosher salt
- •1 tsp black pepper
- •4 sprigs fresh thyme
- •2 sprigs fresh rosemary
- •½ cup pure maple syrup
- •¼ cup bourbon whiskey
- •2 tbsp apple cider vinegar
- •1 tbsp Dijon mustard
- •1 tsp grated fresh ginger
- •½ tsp cinnamon
- •Pinch of cayenne pepper
- •2 tbsp unsalted butter
- •1 tbsp cornstarch mixed with 2 tbsp water
- •Fresh thyme for garnish
- •Flaky sea salt for finishing
Instructions
Score duck breast skin in a crosshatch pattern, cutting through fat but not into meat
Season both sides generously with kosher salt and black pepper
Place each duck breast in a vacuum-seal bag or zip-top bag with 1 sprig thyme and rosemary
Remove air using vacuum sealer or water displacement method and seal
Preheat sous vide water bath to 137°F (58°C)
Submerge sealed bags in water bath, ensuring breasts are fully submerged
Cook for 2 h 15 min for tender, rosy duck with rendered fat
While duck cooks, make maple bourbon glaze
In a saucepan, combine maple syrup, bourbon, apple cider vinegar, Dijon mustard, grated ginger, cinnamon, and cayenne
Bring to a simmer over medium heat, stirring to combine
Reduce heat to medium-low and simmer until reduced by half and slightly thickened, about 12–15 min
The glaze should coat the back of a spoon
Remove from heat and whisk in butter until smooth and glossy
If glaze is too thin, stir in cornstarch slurry and simmer 1–2 min more
Keep warm on low heat
When cook time is complete, remove duck breasts from bags and pat skin completely dry
This is critical for crispy skin
Heat a large cast iron skillet over medium heat
Place duck breasts skin-side down in dry skillet
Cook skin-side down for 5–6 min, spooning off rendered fat as it accumulates
Save the rendered duck fat for roasting potatoes
Increase heat to medium-high and continue cooking skin-side down until deeply golden and crispy, another 3–4 min
Flip and sear meat side for 30–45 sec just to color
Brush duck breasts with maple bourbon glaze during last minute of cooking
Remove to a wire rack and rest skin-side up for 5 min
Slice duck breasts on the bias into 1/4-inch thick slices
Fan slices on warmed plates
Drizzle with additional maple bourbon glaze
Garnish with fresh thyme sprigs and flaky sea salt
Serve immediately with roasted root vegetables or sweet potato mash
Notes
- •Pure maple syrup is essential - avoid pancake syrup substitutes for authentic flavor
- •Score only the fat, not the meat, to prevent juices from escaping
- •Render the fat slowly to avoid burning the skin before fat is rendered
- •The glaze can be made a day ahead and reheated gently
- •Pairs beautifully with fall vegetables like sweet potatoes, Brussels sprouts, or butternut squash
