3. Cover and marinate in the refrigerator for at least 1 hour, or overnight for best results.
4. Preheat your oven to 375°F (190°C).
5. Heat olive oil in an oven-safe skillet over medium-high heat.
6. Sear the duck breast skin-side down for about 5-7 minutes until the skin is crispy.
7. Flip the duck and transfer the skillet to the preheated oven.
8. Roast for 15-20 minutes, or until the internal temperature reaches 165°F (74°C).
9. Let the duck rest for 5 minutes before slicing and serving.
