You can do this by typing an attributename you need in the field "Dissolve Count Attribute". See the documentation:

Dissolve Count Attribute

The attribute identified by this parameter will store the number of input polygons dissolved into an output polygon.

For example, if 3 input polygons dissolved into 1 polygon, then that 1 polygon would have this attribute set to 3.
