Lotsa de Casha debuted at number three on The New York Times Best Seller list. Elaine Stuart from Parenting found humor in the names Madonna gave in the book, like naming Lotsa's castle as "Flasha de Casa" and the mountain on which it is situated as the "Muchadougha Mountains", details she believed would make the readers laugh. Roy Blatchford from Books for Keeps liked the story and rated it four-out-of-five stars. He said that the story avoided any cliche plots, "creates a number of original cameos and bounces along with humour and lively dialogue, clearly influenced by [Madonna]'s Italian New York background." Blatchford complimented Paes' images describing them as "striking" and the design as "eye-catching" thus making Lotsa de Casha "a first-class picture book to grace any library". A review in Publishers Weekly called the story as "artless fable" but believed that Paes' illustrations improved it with the "tongue-in-cheek homage to classic Baroque painting". The reviewer found that in contrast to the grand images, the story appeared simple and the accented edge on Lotsa's words were "uncharacteristic of a rich gentleman". Delgiannakis complimented the "beautifully illustrated" images in the book but found it to be littered with "preachy factoids" like "Just because something is expensive, doesn’t mean it's worth it". Boyd Tonkin from The Independent panned the release, calling it "howlingly egotistical" and a vehicle of "personal gratification" for Madonna, "rather than a virtue in itself". Ilene Cooper of Booklist said that like many other celebrities-turned-authors, Madonna mistakenly thought that she could write books for children.
