Crispy fern

I went away recently and asked a friend to water my houseplants, which she did... except for my small button fern which she thought was fake! It's now very crispy...any hope for it? I've given it a good soak but not sure how far to cut the leaves back, if at all.
Couldn't see a houseplant section, sorry if this is in the wrong place. Thank you!

 

Poor little thing!

Assuming that all the leaves are crispy…
I would be tempted to cut away all of the fronds back to just above the soil/corm (or whatever the fern heart is called). Then keep it moist - you may see some new growth coming from the centre in a month or so. You’ve nothing to lose, after all

 

Thank you Sian, I shall give it a haircut and hope for the best!

 

Looks like a Pellaea rotundifolia
These can take a dry period better than most other ferns.
So it may be salvageable.

Give it a good soak, keep slightly damp, and it will hopefully come back.
