Here we bypass phase-matching constraints by patterning subwavelength 3R-MoS2 flakes to realize non-local optical resonances. By leveraging the large field confinement and high quality factors offered by our metasurface design, we are able to achieve two orders of magnitude (140×) second-harmonic generation enhancement compared with unpatterned 3R-MoS2 flakes with the same thickness, enabling single-pass second-harmonic
