We Are All We Need received generally positive reception from music critics. Matt Joseph from We Got This Covered gave the album a 4/5 rating, stating that the album's "catchy hooks, angelic vocals and club ready anthems" added to the group's already impressing discography. Krystal Spence from Your EDM compared We Are All We Need to Above & Beyond's previous album, Group Therapy, stating that the former was "much more uplifting" than its predecessor. Krystal also praised the group for continuing their tradition of producing tracks which are "easy to learn", allowing listeners to effortlessly sing along with the tracks. inthemix's Angus Paterson noted the focus of club-based tracks on the record, and stated that the album "ain’t something that will please those enthused with the deeper, more progressive sounds heard on their Tri-State debut". He went on by writing that although there was less of a consistent theme which drew Group Therapy together, the record managed to be the "most polished album yet; functioning both as A-grade pop music, and mass-appeal club music with soul." In a mixed review, Jon O'Brien from Music Is My Oxygen described the album as packing with "skyscraping choruses, uplifting synth hooks and Balearic beats", but criticized the track "Blue Sky Action" for being a generic attempt at copying the success of Swedish House Mafia's dance-pop sound and stated that "We Are All We Need delivers little you haven’t heard before". Lanre Bakare from The Guardian and Jessica Wall from The Up Coming both gave the album a 2/5 rating, with Bakare calling We Are All We Need an "overwrought, nigh-on comical take on dance music". Wall dubbed the record as "just a collection a collection of songs", writing that there is no sense of journey and aesthetic amongst its tracks as the record progresses.
