Add all of the marinade ingredients to a blender or food processor. I love using my Nutribullet Pro to quickly pulse small batch marinades.
Alternatively, you can finely mince the herbs and garlic, and add them to the remaining marinade ingredients.
Spatchcock Chicken
Place the whole chicken breast-side down on a cutting board.
Using kitchen shears, cut along the right side of the of the spine/backbone from the tail to the neck. Repeat on the left side of the bone. Discard or reserve for stock.
Flip chicken over (cut side down and breast side up). Press down firmly to flatten- you will likely hear it crack.
Season with salt and pepper and place in a gallon zip-lock bag or large bowl.
Pour marinade over chicken to completely cover. Marinate in the fridge for at least 4 hours, up to 24.
Preheat the oven to 450°F
Slice onion, lime and orange into large wedges and spread around a large baking sheet or roasting pan.
Place chicken, breast side up, on top of the onions and citrus so it is not directly touching the pan. Pour over remaining marinade.
Place chicken in the oven (I use the second highest rack), for 15 minutes.
Reduce the temperature to 400° and continue cooking for 40-45 minutes or until the internal temperature reaches 165°
Remove from oven and let chicken rest for at least 10 minutes. Slice and serve with steamed rice, black beans, and tostones.
