You can use Vector3.Lerp to interpolate between two values.

This following code will rotate the Z of your game object 180 degrees as per the behaviour you described:

  float pct = 0
  float speed = 0.4f    
     
     void Update()
     {
             if (Input.GetKey(KeyCode.Mouse0))
             {
                 if (pct < 1) {
                     pct += Time.deltaTime * speed;
                     transform.rotation = Quaternion.Euler (Vector3.Lerp(new Vector3(0,0,0), new Vector3(0,0,180f), pct ));
                     print(pct);
                 }
             } else {
                 if (pct > 0) {
                     pct -= Time.deltaTime * speed;
                     transform.rotation = Quaternion.Euler (Vector3.Lerp(new Vector3(0,0,0), new Vector3(0,0,180f), pct ));
                     print(pct);        
                     }
                 }
     }

Goodluck
