The series has received positive reviews from critics, particularly for its realistic depiction of gay life in Japan, and is noted as being one of the first pieces of mainstream Japanese media to substantially portray a cohabiting gay male couple.^[19] Writing for Manga Bookshelf, Katherine Dacey praised the series for showcasing "the realities of gay life in Japan depicted in such a matter-of-fact way," while not being "preachy or dreary."^[20] Writing for ComicsVerse, Melissa Padilla cited What Did You Eat Yesterday? as a series that subverts typical LGBTQ manga and anime tropes, noting that it includes a "realistic depiction of a gay couple who are adults rather than high school or college students" and that it "tackles gay issues while still maintaining a leisurely, slice-of-life pace."^[21]

Portrayal of gay domestic life

Writing for Culture, Society and Masculinities, Katsuhiko Suganuma notes that the relationship between Shiro and Kenji is depicted as largely non-sexual, contrasting stereotypical media portrayals of gay men as hypersexual or sexually deviant.^[19] Far from reinforcing equally permissive stereotypes of gay men as emasculated, Suganuma argues that by not depicting Shiro and Kenji's sex life, the series "intentionally ignores the expectations of the curiosity-ridden heteronormative public" to focus on the domestic lives of gay men.^[19] Consequently, he cautions against interpreting What Did You Eat Yesterday? as being merely assimilationist or homonormative, arguing that it "provides readers with occasional instances of modification of gender and sexuality norms in contemporary Japanese society."^[19]

Portrayal of masculinity

Xuan Bach Tran has noted that while cooking media featuring men in Japan typically foregrounds competition and pursuits of excellence, as in series such as Iron Chef and Oishinbo, What Did You Eat Yesterday? depicts cooking as merely a hobby and a necessity for life.^[31] While Shiro embodies many of the traits of the "herbivore man"—he is unambitious in his career, and largely socially withdrawn—he falls out of this category through his love of cooking, and derives his masculinity from "self-care and expressions of selfhood".^[31] Suganuma concurs in Culture, Society and Masculinities that as Shiro's utilitarian cooking style is neither archetypically masculine nor archetypically feminine, it "[distances] itself from a polarized gender binary."^[19]
