4e can cover this if you are willing to be a little loose with the encounter design rules.
If you want a really quick battle use 4 minions or a single standard monster. It should last ~2 rounds and be less than 15 minutes.
If you want something more like a mini-boss battle in a video game, use 2 standards, a standard and 4 minions or a single elite. This should last three maybe four rounds at most and be over in less than 30 minutes.
