I like to take a nice center cut pork loin and cook it in a slow cooker (crock pot) for 8 hours in homemade bbq sauce.
When it's done, take it out, use two forks to shred it, then put the shredded pieces back into the sauce to coat.
Mmmm...homemade pulled pork.
Freezes really well in individual portions, too.
Another option is to use it to marinade a nice rack of ribs or three, bake it on a very low temperature for a few hours (or as long as a day), and then grill or broil them to finish.
I'd say the rib meat probably freezes well too - but ribs never last that long in our house!

BBQ sauce pizza w/ chicken, red onion, cheddar/american, etc...
As sauce for enchiladas, tacos, quesadilas, etc.... BBQ wings.
A
spicy, cheesy casserole w/ corn, green beans, pasta, etc... Add some to spaghetti sauce for a kick.
Obviously, sauce for just about any meat.

The weather is a bit warm for it, but I use bbq sauce in my chili when I make it.

We do ribs in an oven (no grill, but this works great on a grill if you have it) for about 2 hours wrapped in foil, remove foil, and add barbecue sauce at the end to cook on.
We do a spice rub to begin with.
Truly tasty!

We make our own pizzas and one thing we like to do is mix BBQ sauce with the tomato puree to go on the base - gives it a bit of a twist from normal pizza.
Also, often I'll squirt a bit into shepherds or cottage pie with the meat to make it a bit different from normal.

I haven't tried it with barbecue sauce, but I've had good luck freezing other sauces.
Could you freeze it in batches large enough for one generous order of barbecued meat?

We found a nice recipe lately for barbecue sauce and made 3 variations to test out. The problem is: now we have ~3 pints of homemade barbecue sauce that we need to use before it goes bad. (It won't last nearly as long as store-bought stuff with all of their preservatives).  What are some tasty ways to use up our new sauce?

You can cook meat in it, add it to pizza and pasta sauces, chili, casseroles and other dishes. It can also be used as a sauce for meats, enchiladas, tacos, quesadilas etc. Finally, you can freeze it in individual portions. You can use it to baste roasting meat, and mixed into other recipes like spaghetti or pizza. It also freezes well.
It would be a good sauce for roasting any meat. You can use it on pizzas, tacos, in a casserole or in spaghetti sauce. It will freeze well in portions.
