I used to mash them with potatoes. Not all that inspiring but never the less.
They have a nice , sweet earthy taste. DS still loves beets and he started eating them pickled at about 2 yrs. We can our own. I wanted to mention and maybe you are aware but for any others, that when preparing beets they are messy and stain a lot on counters etc... If you can get them at the market already boiled, this helps out a lot in the preparation as it feels as if you have to boil the bu**ers forever! Also don't panic when you see red/orange pee in the nappy/diaper or red/purple poos. I still sometimes forget and have a mini panic attack with myself or DS that we are bleeding internally!
LOL!
Also wanted to mention to visit this fab website if you already haven't, they have loads of recipes and info but also recommend that many pediatricians suggest introducing beets between 8-10 months of age dues to nitrates.
