Step 1: Make the marinade

In a large bowl, stir together the Worcestershire sauce, olive oil, minced garlic, hot sauce, and black pepper until combined.

Step 2: Coat the duck

Add the duck breast halves to the bowl. Turn each piece until coated on all sides with the marinade.

Step 3: Marinate in the refrigerator

Cover the bowl and refrigerate for at least 30 minutes or up to overnight. Keep the duck refrigerated throughout the marinating time.

Step 4: Preheat the grill

Preheat a clean grill to medium-high heat. Lightly oil the grates if needed to reduce sticking.

Step 5: Remove the duck from the marinade

Lift the duck breasts out of the bowl, allowing excess marinade to drip off. Discard the used marinade.

Step 6: Grill the duck

Place the breasts on the preheated grill. Cook for approximately 5–7 minutes per side, turning once, until grill marks develop and the meat is cooked through.

The exact time depends on the thickness of the breasts and the temperature of the grill.

Step 7: Check the internal temperature

Insert an instant-read thermometer into the thickest part of each breast. The Grilled Wild Duck Breast is ready when it reaches at least 165°F (74°C).

If the exterior is browning too quickly before the center reaches temperature, move the duck to a cooler part of the grill and continue cooking.

Step 8: Rest and serve

Transfer the duck to a clean plate and let it rest for about 5 minutes before slicing. Serve warm.
