Crock Pot Cola Chicken

1 whole chicken (1 1/2-2 lbs) or bone in, skin on chicken breasts
1 cup ketchup
1 large onion, thinly sliced
1 cup your favorite cola

Generously season chicken with salt and pepper and put in the crockpot. Toss the onion on top and pour the cola/ketchup mixture over it all. Cook on low 6-8 hours. Check every few hours to make sure chicken does not get too dry. If it is drying out, add a splash of chicken broth.

Shred chicken and serve on buns.

Some notes: Of course you would want to use Coke for this, because Pepsi is gross. You can use Diet Coke (or I suppose Pepsi. Blech.) if you don't want the sugar/calories/points from the regular. If you decide to use regular Coke, try to get the Mexican Coke, because it contains real sugar and not High Fructose Corn Syrup. You can find it at Mexican grocery stores/convenience stores, or locally at Piggly Wiggly.
This ends up tasting like a BBQish chicken. If you want, you can add a dash or two of liquid smoke to the shredded chicken.
You can remove the skin from the chicken if you don't want the fat from the skin. There is a better chance of your chicken drying out without the yummy fat from the skin, so keep an eye on it.
