My bandsaw blade is a 3 tpi Olson which leaves small serrations but when i do this "for real" I will face joint before each cut so as to glue smooth to smooth surfaces.
There are two tricks that have helped me reduce this problem.
One is a zero clearance bandsaw insert. Search term > zero clearance bandsaw insert < and you will find a lot of sources.
Second is some bandsaw blades have too much set, imo. With two metal plates in my vise the blade is carefully fed between the plates and is clamped on a few inches at a time to decrease the set.
These both help even with a coarser blade.
