Travelling to Italy, with my EU national

I have a question, I am planning a trip to Italy in 4 weeks, but I am confused about my documents. I used to live in Italy (for 18 years, I have pakistani nationality) and my mother is an Italian citizen. I have a “Permesso a Soggiorno”.

My mom moved permantly to the UK 1 year ago, because of work and I joined her too. I got a residency card (family member of eu citizen). Can I travel with my Mom with my residency card ? Or with Permesso di soggiorno ?

We’re going only for a week.
