Preheat your oven to 180°C (350°F).
In a baking pan, toss your diced potatoes with 1 tbsp of crushed garlic, a pinch of salt, pepper, and a drizzle of olive oil. Use your hands to coat the potatoes evenly—getting a little messy is half the fun!
In a separate bowl, add the chicken pieces, zest, and juice of the lemons, 2 tbsp of crushed garlic, and a sprinkle of salt and pepper. Massage everything together until the chicken is well coated in that citrusy, garlicky goodness.
Arrange the chicken pieces on top of the potatoes in the baking pan. Pour any leftover lemony juices from the bowl over the chicken.
Pop the pan into your preheated oven and bake for 40 minutes, or until the chicken skin is crispy and the potatoes are golden and tender.
