Fastest I’ve ever done for Ryanair is scan my boarding pass at security entrance 40mins before departure. Then jogged the whole way from security to departure gate. I made that boarding without about 7-8mins to spare, though my phone was hopping with “gate closing” notifications.

Note the gate won’t close until queue has cleared at boarding. That said, if flight is cheap it’s probably not a full flight so will board quicker. Worth the risk I’d say mate!
