Instructions
1) Prepare the sous-vide
- Preheat your sous-vide bath to 58°C (136°F).
- Pat the duck breasts dry. Score the skin in a light crosshatch pattern without cutting into the meat.Season both sides with salt and pepper.
– lightly coat each breast with 1/2 teaspoon avocado oil and place skin-side up in two vacuum bags. Seal using your preferred method.
2) Sous-vide cooking
– Submerge the sealed bags in the water bath and cook for 90 minutes to 2 hours. The meat will come out tender and evenly cooked.
3) Make the glaze
– While the duck cooks,combine coconut aminos,grated ginger,minced garlic,lime zest,lime juice,fish sauce (if using),and chili flakes (if using) in a small saucepan.
– Bring to a gentle simmer and cook 2–3 minutes, stirring occasionally, until the glaze thickens slightly. Remove from heat and keep warm.
4) Sear the duck
– Remove the duck from the bags and pat vrey dry (this helps crisp the skin).
– Heat a skillet over medium-high with 1/2 tablespoon avocado oil. Place the duck breasts skin-side down and sear 2–3 minutes until the skin is deep golden and crisp. flip and sear 1 minute on the meat side. Remove from heat and let rest 5–7 minutes; slice just before plating.
5) Sauté the greens and mushrooms
- In the same skillet, melt 1 teaspoon butter over medium-high heat.
– Add the oyster mushrooms and zucchini ribbons. sauté 3–4 minutes until just tender and nicely charred in spots. Season with a pinch of salt.
6) Plate
– Slice the rested duck and arrange on plates with a portion of the zucchini ribbons and mushrooms.
– Drizzle the coconut-ginger-lime glaze over the duck.
– Garnish with lime zest and cilantro or microgreens if desired.
Tips & Variations (core recipe substitutions)
– Protein swap: Try skin-on pheasant breast or skin-on chicken thigh halves for a different aroma profile while keeping the keto macros intact.
– Floral/heat tweak: Add a small pinch of white pepper or a few crushed pink peppercorns to the glaze for a subtle aroma shift.
– Veg swap: Swap the zucchini ribbons for peeled asparagus spears or baby spinach to vary texture; adjust carbs accordingly.
– Dairy-free option: Omit butter for the sauté; use a drizzle of extra-virgin olive oil rather.
– Make it spicier: Increase chili flakes or add a few thinly sliced fresh chilies to the glaze for more heat without adding sugar.
