At present you have 17 years to your anticipated retirement. So you have time and that is very important, you are looking at this now and not in ten years time.
It is very difficult to answer "how much" as that is very dependent on your own life needs and lifestyle. It would be a sensible exercise to observe your own life and work out exactly how much you will probably need to live on post-retirement. Do it in today's terms, don't try to project what €100 will buy in the future, work out what proportion of your €60,000 income you need to live on comfortably now, don't think about being parsimonious, think about being comfortable, you want to aim for a liveable income that means you can see yourself living that lifestyle over say 30 years. So if you determine that actually you can comfortably live on €20,000 (after tax), then you have an idea of the sort of income you would need from a pension, on top of the contributory pension that you would be entitled to.
Looking at your comfortable life will answer another question, how much additional money would you be able to contribute in the interim. You may also be able to identify a liveable but less comfortable life, cut backs in your current lifestyle that you wouldn't want to maintain for 30 years but you might be willing to accept for a few years in order to build your pension pot.
That will give you a rough idea of your personal target fund (i.e. what fund would reasonably support the and what income you have now to work with it. The next things to look at would be to look at your contributory record. Request a statement of contributions from the Department of Social Protection. There is an online service if you have a myGovID account
https://services.mywelfare.ie/en/topics/statements-and-refunds/contribution-statement/ or you can write to them in Sligo to request it.
Once you have all that done you can decide your path. Review it every year, it's not set in stone.
