An easy overnight marinade for the roast chicken of your dreams.
Combine the first 5 ingredients in a food processor and blend until smooth. Add the oregano, honey, salt, pepper, and lemon zest and whir again. Finally, add the capers and juice and pulse just 2-3 times to combine. You want some of the capers to remain whole.
Remove the chicken from the fridge and let rest at room temperature for 30-45 minutes. Pre-heat oven to 375°. When ready to bake, uncover the dish and turn the chicken breasts over so that they are breast-side up. Top each chicken breast with a slice of lemon and bake for 45-50 minutes (less time if using boneless chicken breasts) or until the juices run clear.
Transfer the chicken to a platter and generously spoon pan sauce over each breast. If desired, you can serve any remaining sauce on the side.
