How much inductance?

If a few hundred microhenries, you can deal with back-emf by a snubber
network of reasonable size.

If more than a millihenry or two, you would need a varistor or zener to
prevent breakdown triggering of the triac.

In principle, a solid state relay or triac can be used for such an
application. In practice you need to know a little about snubbing design.

A relay would solve your problem with less knowledge required, although you
would still want a snubber network across the relay points and a diode
across the relay activation coil.
