One of five goal scorers on the night, Gnabry's performance highlighted both his finishing prowess and his ability to thrive in a fluid, multi-pronged attack.
Gnabry, reflecting on the match, said the team had brought "fun" back to the pitch, a sentiment that underlined the joy and confidence Germany displayed after a run of four consecutive wins.
Previously criticised for a blunt attack, the German squad looked revitalised, with Gnabry's incisive movement and sharp finishing serving as a template for the new approach.
While Nick Woltemade played a key role in spearheading the offence, Gnabry's contributions stood out, combining technical skill with intelligent positioning to exploit Slovakia's defensive frailties.
The goals were spread among multiple players, but Gnabry's influence extended beyond scoring, providing crucial link-up play that allowed others to find the net.
"It was a very good game," said Gnabry, as captured by @iMiaSanMia.
"We had a lot of fun on the pitch. We knew that we had to show a better performance than the one we did on Friday.
"There are still things to improve, but if we play like we did today, we can achieve big things. Today was a great feeling."
A late goal from Germany demonstrated both excitement and improvement in performance, with the manner of victory being as significant as the scoreline itself.
Coach Julian Nagelsmann could now have Gnabry at the centre of a squad poised for a strong showing at the next FIFA World Cup.
