1992 marked the beginning of Lascher's run on "Blossom", and his portrayal of the cool but kind Vinnie would win him many fans and admirers. On breaks from "Blossom" he found the time to complete featured roles in the fact-based TV movies "The Flood: Who Will Save Our Children" (NBC, 1993) and "Cries Unheard: The Donna Yaklich Story" (CBS, 1994). Lascher continued to be a consistent presence on the small screen, acting in the NBC TV-movies "Twisted Desires" and "Kidz in the Wood" in 1996, the same year the performer made his feature debut in Ridley Scott's seafaring adventure "White Squall". Though the film was largely pegged as a shirtless retread of "Dead Poet's Society", the scenes battling the titular wave of death were suitably thrilling, and Lascher did a fine job in his supporting role. A follow-up feature role as the son of American immigrant Holocaust survivors who learn their presumed-dead son is alive in the 1960s-set "A Call to Remember" (aired on Starz!/Encore in 1997 in lieu of theatrical release) proved the actor a capable dramatic player. Back on television, he essayed the role of Cher's idealistic "pseudo-stepbrother" Josh in the ABC TV series adaptation of the hit teen comedy "Clueless" from 1996-1997 and played the irresponsible uncle of the Olsen twins on their ABC sitcom "Two of a Kind" in a 1998 to 1999 recurring role. A two-episode stint on "Veronica's Closet" cast him as a young love interest for Olive (Kathy Najimy) while a regular role on "Sabrina, the Teenage Witch" (The WB) beginning in 1999 paired him with Melissa Joan Hart's college-bound conjurer.
