Narrative:

Encountered wake turbulence on visual approach to 23 in clt. We were cleared down to 4000 ft. To intercept the glide slope at atell. We were about 1 dot below GS at assigned altitude of 4000 ft. When the airplane hit wake and rolled right past a 45 degree angle (estimated). My first officer was flying; but I immediately clicked off the autopilot and rolled the aircraft level. It took a couple seconds as the aircraft reacted very slowly even with near full deflection back to the left. We advised ATC and continued the approach just above GS.[caused by] wake from an A321 3 miles ahead of us.[recommend] better descent clearances to avoid descending wake from interfering with aircraft intercepting GS at lower altitude.
