I tried fill flash yesterday shooting an outdoor portrait. All it did was completely wash out the subject.
I tried it first with my 430EX and then with the pop up flash. Both did the same thing.
Is there an actual "fill flash" setting on the Rebel XT that I have to be in? Do I have to compensate for the fill flash by underexposing the picture?
I've never tried fill flash before and my first attempts were absolutely horrible, what am I doing wrong?

Try setting the 430ex flash to high speed sync so that you can use a realtively high shutter speed or dial down the Flash Exposure Compensation on the flash unit and/or camera or even switch over to fully manual, take a test shot and adjust the shutter speed or aperture in camera.
Post your outtake and let us see what happened

Depending on the amount of ambient light (which can be a LOT outdoors) you may have to use ND filters to control the light more.
For instance my Sigma flash on my 300D has a max sync speed of 1/200. That often leaves me with very deep DoF in bright sunlight - not something I really want for portraits.

try turning down the amount of flash that is being output, either on the flash itself, or using the camera body to control it,
then use a f/8-f/11 try to go more on the f/11 side, or higher if can, remember you only need 1/60th shutter speed so that you can get tha sky in there and not blown out,
that should help, i know there ETTL on the 430 probably isnt that great, im not even sure if the 430ex even has ETTL
what lens where you using ?
since you have a 1.6 crop, back up a little and either turn up or turn down the amount of flash,

You could also take a step back from the subject. I was trying to take a picture last week of a man wearing a cowboy hat. It was sunny out, so the hat was casting a serious shadow over his face. I only have an on-board flash, and how I more-or-less resolved it was to physcially move a little further away and zoom a little closer. Do you get what I mean?
Can I post the picture? It doesn't look anything like my entry, although it almost was my entry... |

If you're shooting in quite bright light, the exposure time may need to be, say 1/1000 of a second. The maximum shutter speed that the camera can synchronise with a flash unit is probably 1/250 of a second. When the on-board flash is popped up or if an external flash is mounted, the camera can detect it and reacts accordingly, by limiting the shutter speed. This may mean that you ended up with an exposure time much longer than needed at the aperture that you were using. In other words, do as Tallbloke suggested and set the external flash to high speed (FP) mode. It should all work pretty automatically then.
