Place the chicken breast side down, on a large pan or work surface.
Starting at the thigh end, cut along one side of the backbone with your kitchen shears.
Turn the chicken around and cut along the other side. Save the backbone for stock if you like.
Flip the chicken over and open it like it's a book. Press pretty firmly on the breastbone to flatten it. Chicken is ready.
Make the marinade
Add the water, olive oil, bouillon cube, the dry oregano, fresh herbs, mustard, lemon juice and lemon zest and honey in your food processor. Pulse until everything is well mixed and garlic is fully minced.
Pour marinade all over chicken. Make sure it gets everywhere, in any nook and crany.
Prepare the potatoes
Heat 4 tbsp olive in a large pan (I used a large cast iron pan)
Add the potatoes, season with salt pepper, a generous pinch of dry oregano. Add a couple of thyme sprigs in the pan.
Cook potatoes until they are golden. Remove from heat and set aside.
Prepare for oven
Add the potatoes in the baking pan of your choice. I used the same large cast iron so I left potatoes as they were.
Place spatchcocked chicken on top of the potatoes. Pour left over marinade all over.
Cover with alumimum foil and cook in the oven for 45 min.
Uncover and cook for another 20 min or so. Keep basting the chicken with the marinade juices from the pan. Cook until chicken is cooked through and juices run clear.
Notes
You can cook the chicken right away or let it marinate for a day in the fridge. The longer you leave the marinade on the juicier the chicken will be. Don't marinate longer than two days.
