I don’t know if this is authentic enough (the recipe writer definitely is not Greek) but this chicken has lots of lemon and oregano and it’s really delicious. I haven’t tried it with anything besides thighs, but it seems like you could easily swap in whole chicken parts, throw in some potatoes, and scale up the recipe. I make it regularly and everyone loves it.
