In strong-field laser-matter interactions, energetic electrons can be created by photoemission and a subsequent rescattering and can attain energy as much as 10 times the ponderomotive potential (

U_{p}

) of the laser field. Here, we show that with the unique combination of infrared laser sources (exploiting the quadratic scaling of

U_{p}

) and plasmonic nanoemitters (which enhance rescattering probability by orders of magnitude)

\sim 10 U_{p}

rescattered electrons can be observed in the multiphoton-induced regime. Our experiments correspond well to a model based on the time dependent Schrödinger equation and allowed us to reveal an unexpected aspect of ultrafast electron dynamics in the multiphoton emission regime.
