No. Best turn your oven up to max, and cook chicken in a shallow tray.Can i cook tandoori chicken in a tagine and will it taste authentic?
Cook it in an oven on high heat. Place chicken on a rack in a shallow pan so the heat can circulate all around the chicken.
Not really Tandoori is cooled in a deep clay oven, and quite high heat (dry) but you can do it (sort of) in an oven (hot) and a clay pot. Dry.

I would think that a tagine would dry out the meat too much
No. The tast will be very different.
No A tagine will steam it. Tandoori chicken is cooked in an oven.

Itcan be also cooked in a gas or electric oven, but it will lose

most of its flavour. Also, the chicken has to be marinaded for

at least 6 hours, ideally 12 hours overnight.
