There are a lot of tried-and-true programs that include multiple squats a week. Stronglifts is one, but there are programs from Glenn Pendlay, Bill Starr, Mark Rippetoe, etc. and they're all good for beginner to intermediate lifters - and they all feature two or three days a week of the same-old squats. A beginning lifter should make gains in the squat even while doing it three times a week, sometimes for many months. After you hit the wall, programs will drop the number of squat days, replace a day of back squats with the front squat, or replace all-heavy days with a light-heavy-medium rotation. It's true - you'll eventually plateau. But a 3x week squat program works for a lot of people, especially when starting out.
