Steps
1. Score the skin of the duck breast in a crisscross pattern and season with salt and pepper.
2. Heat the vegetable oil in a skillet over medium-high heat.
3. Place the duck breast skin-side down in the skillet and cook for about 6-8 minutes, until the skin is crispy and golden brown.
4. Flip the duck breast and cook for another 3-4 minutes for medium-rare or longer for desired doneness.
5. Remove the duck breast from the skillet and let it rest for a few minutes.
6. In a small saucepan, combine orange marmalade, soy sauce, honey, orange juice, and orange zest. Heat over medium heat until the mixture is heated through.
7. If desired, mix cornstarch with a little water to create a slurry and add it to the sauce to thicken.
8. Slice the duck breast and serve it with the orange glaze drizzled on top. Garnish with fresh parsley.
