Pound the thick ends of chicken breasts gently to an even 3/4-inch thickness. Stir yogurt, oil, lemon juice, paprika, coriander, garlic, salt and pepper together.
Place chicken and marinade in a labeled gallon freezer bag, massage to coat, remove excess air and seal.
Freeze before cooking: lay flat on a tray and freeze promptly for up to 2 months. Thaw the sealed bag on a rimmed tray in the refrigerator for 24 hours.
Heat the oven to 425°F and line a rimmed metal pan with foil. Lift chicken from the bag, scrape off thick excess marinade and arrange with space between pieces; discard the bag and leftover raw marinade.
Bake for 20 to 25 minutes until the thickest part of every breast reaches 165°F. Rest for 5 minutes and serve one breast per portion.
Refrigerate cooked leftovers within 2 hours. Reheat covered with a little broth at 325°F for 15 to 20 minutes until the center reaches 165°F.
