We demonstrate the number-resolved detection of individual strontium atoms in an optical tweezer. Using a long-working distance low numerical aperture (NA = 0.26) tweezer, we avoid parity projection due to light-assisted collisions, and are able to resolve up to N = 3 atoms within an imaging time of less than 300 $\mathrm{\mu}$s. We also discuss the methods for the measurement of the atomic temperature and trap parameters.
