Blue with Lou received a score of 75 out of 100 at review aggregator Metacritic based on seven critics' reviews, indicating "generally favorable" reception.[3] Uncut remarked that "Lofgren's voice is crackly, but plays perfectly", and Classic Rock called it "a pleasant album and one that covers a lot of bases", while Mojo felt that "the Reed/Lofgren songs muscle their way to the top of the pile".[3] Glide Magazine stated that "the 'less is more' premise remains in effect just often enough on Blue with Lou to certify the record, name associations aside, as a memorable entry in the lengthy discography of Nils Lofgren".[2]

Stephen Thomas Erlewine of AllMusic wrote that "Lofgren achieves a lean, sinewy sound that gives the tight group plenty of room to roam" and while "Lofgren's originals may not carry the same swagger, [...] when they're surrounded by these Reed co-writes, they're given a slight lift: the whole affair simultaneously feels like an affectionate tribute to a departed friend and a resuscitation of Lofgren's gut-level rock & roll".[4] PopMatters' staff opined that "Lofgren rises to the occasion, playing with a sense of abandon and danger that recalls his best work with Grin and blistering, if overlooked, live albums, including 1977's indispensable Night After Night".[1] Hal Horowitz of American Songwriter noted that despite the passage of time since the material was written, "little has changed with [Lofgren's] youthful sounding voice, sizzling guitar playing, melodic songwriting or overall boyish enthusiasm. That makes this comeback of sorts particularly sweet, irrespective of Reed's beyond-the-grave involvement".[5]
