Steps
1. Preheat oven to 400°F (200°C).
2. Score the skin of the duck breast in a crisscross pattern, being careful not to cut through the meat. Season with salt and pepper.
3. Heat a cast iron skillet over medium-high heat. Place the duck breast skin side down and cook for about 5 minutes, until the skin is crispy and golden brown.
4. Flip the duck breast and transfer the skillet to the preheated oven. Cook for another 8-10 minutes for medium-rare or until desired doneness.
5. While the duck is cooking, prepare the orange glaze. In a small saucepan, combine orange marmalade, soy sauce, rice vinegar, honey, grated ginger, and minced garlic. Heat over low heat until the marmalade is melted and the glaze is well combined.
6. Remove the duck breast from the oven and let it rest for a few minutes. Brush the top with the orange glaze.
7. Slice the duck breast and serve with the remaining orange glaze on the side.
