I know this question is out of season but I've got this nice cold weather sleeping bag which is huge when rolled up and in its bag. How can I backpack with the thing? The only way I can think of is tying it onto the outside with rope but this doesn't seem like it would be secure enough

Strap is to your pack with a bungee or two. It'll be fine. I've done this dozens of times with bulky cold weather gear. Weighs you down a bit more in the back but it works.

Back in the day (early 90s), any remotely serious hiking pack had an assortment of attachment points so you could strap a sleeping bag to the bottom with 2 webbing straps. Or alternately under the lid of a top loader, but a winter bag might be too big for that.
Get a compression sack, OP. Cinch that bitch as tight as it goes, and strap it on

This ruin the bag. If you want to buy a new one every year it will save you precious space in the backpack. If you want it to last, forget about it.
If it is a synthetic put it in a light weight dry sack, and attach it to the outside of the bag using wide cut webbing. If it is down, especially goose down, get a compression bag (preferably water resistant, if not throw it in that dry bag).

Get a Canadian 64 Pattern Ruck
Canadian Army winter weight sleeping bags are fucking enormous when fully assembled (inner, outer, liner, and bivi sack), and the 64 Pattern handles that easily. There are civilian knock-offs, but the frame is the key part of the ruck. Maybe you can jury rig an ALICE frame or something, but the key is an external frame that you can strap a bulky valise to.
There's also the 82 Pattern that has the valise on the bottom, but they aren't anywhere near as comfortable as the 64 Pattern, as they have a wire frame instead of an aluminum tube frame, and they distribute weight poorly.
Buy a better bag.
