Less than 24 hours after winning the 1500m, the 17-year-old Ingebrigtsen sensationally banked his second gold with an even more remarkable run in the 5000m, leading a family one-two in a European junior record of 13 minutes 17.06 seconds.
Older brother Henrik took silver and France's 10,000m champion Morhad Amdouni bagged bronze.
No athlete had ever achieved the European 1500m-5000m double but now, in the space of two days, Ingebrigtsen the younger has achieved it while still a junior.
Just as he did in the shorter race on Friday, Ingebrigtsen stole the show, moving through the field gradually as the laps ticked by before taking the lead with 800m to go.
He led at the bell from Henrik with Amdouni closing in third and remained in control through the penultimate 300m before moving smoothly away down the home straight.
Henrik hung on to second in 3:18.75 while Amdouni picked up his second medal of the championships.
Asher-Smith clinched a second medal too as she backed up her victory in Tuesday’s 100m with another awesome display of sprinting to beat Netherlands' two-time world champion Dafne Schippers for the second time in five days.
The Briton crossed the line in 21.89 seconds, beating her own national record with the quickest time in the world this year.
Schippers was second in 22.14 and her Dutch team-mate Jamile Samuel third in 22.37.
While Jakob Ingebrigtsen was making history on the track, Sandra Perkovic was doing the same on the infield as she lived up to her promise to win a fifth successive European championships gold in a single event.
The Croatian world and Olympic champion retained her discus title with a fifth-round throw of 67.72 metres that pushed Germany’s long-time leader Nadine Muller into second. It was late flourish from Perkovic, inspired by the sudden and unexpected presence of her mother in the crowd.
There was some field event success for the hosts, though, as Mateusz Przybylko won the men’s high jump with a clearance of 2.35m and Malaika Mihambo triumphed in a tight women’s long jump final. She leapt with 6.75m to win with just seven centimetres separating the top four.
As defending champions, Belgium were always the justified favourites for the men’s 4x400m relay but they needed a special performance from Kevin Borlee to bring the baton home ahead of Great Britain and Spain.
The women’s 4x400m relay went to Poland as Justyna Swiety-Ersetic won her second title of the night following a narrow victory in the individual 400m final just an hour and a half earlier.
Her compatriot Adam Kszczot won Poland's third gold of the night, becoming the first man to win three European 800m titles. He clocked 1 minute 44.59 seconds to triumph ahead of Andreas Kramer of Sweden.
