Born in Copenhagen, Ilsø started his footballing career at local amateur club BK Pioneren. He subsequently was joined by his brother Marco Ilsø, playing for several youth teams in Copenhagen. In 2004, he was signed as a youth player by Dutch side SC Heerenveen, after being labelled as one of Denmark's finest talents. On 16 April 2006, he made his senior team debut for SC Heerenveen, also his only senior appearance with the club, in an Eredivisie match against AZ Alkmaar as a 75th-minute substitute for teammate Arnold Bruggink.

SC Heerenveen
Following his first-team debut with SC Heerenveen, Ilsø never managed to make another senior team appearance for the rest of his time at the club. He had a brief loan spell with FC Zwolle on-loan from SC Heerenveen, but did not make a single appearance for the Dutch club.

FC Midtjylland
In summer 2009, Ilsø was signed by FC Midtjylland, who ended in the fourth spot of the Superliga the prior season. Ilsø quickly became an important player for FC Midtjylland. For instance, in the 2010–11 season opener against Silkeborg IF, Ilsø scored the decisive goal to earn a win for the club.

Fortuna Düsseldorf
Following his performance with FC Midtjylland, Ilsø joined 2. Bundesliga club Fortuna Düsseldorf on-loan in the 2010 winter transfer window. Fortuna Düsseldorf subsequently signed him permanently in the following year's summer transfer window, for a reported fee of €300,000.

Bundesliga after a single season in the top flight as the aggregate score of the play-off ended in a 3–4 loss.

VfL Bochum

Home United
In January 2015, Ilsø signed a contract with Home United to play for the remainder of the season. Before he signed the contract, he attracted the interest of several clubs from his home country, as well as from Thailand, but Ilsø wanted to embark on an adventure far away from home.

Ilsø notched his 4th of the season in his 4th consecutive league match for Home United, scoring the first goal of a 2–2 draw against Brunei DPMM.

On 23 December 2015, it was confirmed by Home United that Ilsø will be staying with the club to participate in the 2016 S.League season.

Home United coach, Philippe Aw, was chosen to manage the Singapore Selection side for the 2016 Sultan of Selangor Cup. Ilsø was selected in the 18-man squad for the cup tie that took place at the Shah Alam Stadium on 7 May 2016. Ilsø featured for the entirety of the match which eventually ended 1–1 (3–4 on penalties) in a win for the Singapore Selection team.

In a S.League fixture against reigning champions Brunei DPMM, Ilsø scored 2 of Home United's 5 goals in an eventual 5–0 win, bringing his personal tally to a total of 6 goals in his last 5 competitive games. The win also represented Home United's fourth successive win in the S.League, last achieved by the club in the 2013 S.League season. Ilsø went on to extend his goal scoring streak to a record 8 goals in his last 7 league games after netting once each in S.League fixtures against Young Lions on 11 June 2016 and Albirex Niigata (S) on 18 June 2016.
