Preheat the oven to 400°
Make Garlic Lemon Sauce: Smash the garlic cloves and add them to a small bowl. Sprinkle ½ teaspoon salt over the garlic. Wait 2-3 minutes. Smash the garlic to a paste the best you can with a fork. You can also grate the garlic on zester or micro blade or use mortar & pestle. Once smashed & an intense garlicky paste, add lemon juice & olive oil. Quickly stir together and set aside (it will separate).
Season Chicken: In a small dish mix garlic powder & paprika. Set aside. In a large, oven safe skillet like a cast iron, heat up the avocado oil on medium high until just smoking. While waiting for cast iron to heat, season chicken with salt & black pepper on the skin side. Flip the chicken on your cutting board or plate (skin side down) and season meat with HALF of the garlic powder/paprika mixture along with a bit more salt & pepper. Set aside the other half.
Sear Chicken & Potatoes: When oil is hot, place the chicken pieces in skin side down and sear 5 minutes or until skin is very golden and crispy. Remove chicken and place seasoned side down on cutting board or plate. Add cut potatoes to hot oil/chicken fat carefully. Toss slightly and let the potatoes sit 5-7 minutes themselves until most of the side in the oil is golden, brown and beautiful. While potatoes are par-cooking, season the crispy skin side of the chicken with the other half of garlic powder & paprika mixture.
Bake Chicken & Potatoes: Place the chicken pieces (seasoned, skin side up) on top of the potatoes. Finally, grab your garlic lemon sauce. Give it a quick whisk with a fork or whisk and pour over the chicken and potatoes. You can get some on the skin! Bake the chicken and potatoes 20 minutes OR until chicken is cooked through and potatoes are tender.
Serve hot & sprinkle with fresh parsley or any other light, green herb you may have lying around. Drizzle with extra sauce at the bottom of the pan. Serve as-is, over a bed of arugula, with a salad, or your favorite green veggie.
