Or so... Not having a running stopwatch, I was SWAGing the time based
on my recollection of a flight about a week ago.

Sorry...to me, the "or so" implies the time could have been even longer. I
misinterpreted what you wrote, I guess.

How long does it
typically take to recover airspeed after encountering wind shear (note
spelling).

Depends on the airplane, power setting, trimmed airspeed, and of course the
amount of airspeed lost. But that said, I'd "guesstimate" a recovery of 15
knots would take less than 30 seconds with no power change from a normal
cruise setting (with most of the airspeed recovering much sooner), and much
less (maybe 10 seconds max?) if the pilot recognizes the wind shear and
increases power to compensate.
