CR 11 dragon? Which size? I guess smaller than Huge. Easy.
Monk1/Druid9. Wildshape into giant octopus, cast Barkskin, Greater Magic Fang and Animal Growth on yourself, get some grappling feats and cast the respective Resist Energy spells. Start with some summoned monsters (in emergency cases, a scroll of summon natures ally 6 should be enough for another giant octopus).
Most CR 11 dragons don't have spells to counter all that stuff and will have problems to hit your AC which should be easily above 30.
