A friend at work gave me some kohlrabi that were too big and tough for raw snacking, so here’s what I did with them. The onions needed to be cooked longer and I think it would be much better with some salt, which I left out for health reasons, but the basic idea worked.
3 medium kohlrabi
Peel + chop kohlrabi. Put in crock pot (Or pan- it might be quicker that way), add bay leaf, cover with broth, and cook until tender. Remove the bay leaf. Puree with a stick blender.
