 Robert Canning of IGN felt that "Grilled Cheesus" was too varied tonally, failing to effectively bring together the "true anguish" of Kurt's storyline and "lunacy" of Finn's.He rated it 7.5/10, signifying a good episode, though his overall opinion was mixed.Canning commented that the Hummels' relationship is "the most affecting" of the show, and praised O'Malley's "outstandingly nuanced" performance as Burt, yet felt that the religious element gave the episode an after school special vibe and almost became "over-the-top preachy and self-important".
