Iron Sky
Procedurally Generated
In the game I'm running 3/4 of the fights have been the only fight of the day. What that means is, if I'm pretty sure it's going to be the PCs only fight, I pull out all the stops: Level+3 (or more encounter), coming up!
This does mean that there might only be 2-3 fights at a given level (since I give out xp for roleplaying and skill challenges too), but once I got over my initial resistance to the fact that they'd be leveling up every second or third session, it stopped being a problem.
Our games are a bit different from the norm I think though; I've been DMing for 15 years and I've never had a "dungeon crawl" that took more than one session to complete and, until we hit Paragon in the 4e campaign that my buddy ran, I'd never played through a dungeon crawl either. It was actually really exciting for us since it was the first one we'd ever done!
