This Slow Cooker BBQ Sauce is from a family recipe that's been adapted for the crock-pot. A delicious Southern sweet and tangy sauce that's so easy to make, you'll never use store bought bottled sauce ever again!
A sweet and tangy BBQ sauce perfect for grilling or smoking
If you follow me on Instagram or Facebook, you know I've been all about grillin', smokin', and chillin' as much as possible.
I love barbecuing on my Pit Barrel Cooker, which is a refined version of a UDS smoker (Ugly Drum Smoker - the kind made out of a 55 gallon drum).
This thing is great since you hang the meat over the coals and the fat drips on the fire creating the moisture and flavors of whatever you're cooking.
Also, due to the design it allows me smoke a shite ton of meat at the same time.
All that smoked meat needs a lot of tasty sauce on top and it has to be homemade!
Because no one should ever spend a half a day smoking meat, just to ruin it by coating it with a sauce in a bottle.
How to make bbq sauce from scratch
I have such fond memories of this family recipe. Every time my Mom made this sauce, I would find myself following the delicious smell into the kitchen and peering into the tall stainless steel pot.
I would take the wooden spoon next to the stove and gently stir the thin sauce around the pot, being careful not to disrupt the floating lemon slices.
The rich red color of this southern vinegar based sauce with the tangy smell, is a childhood memory I cherish to this day.
I remember having the self-proclaimed title of "official taste tester" of the sauce and my duty was making sure the sauce was at it's best.
In fact, I took my job very seriously and I would continue to taste many times throughout the day.
It's a good thing my Mom always made such a large pot of this sauce because I probably ate 2 cups of it while exercising my official title.
I still have a deep love for this spicy sauce and always make it whenever I need a barbecue sauce at home.

To make the slow cooking process a little easier, I adapted the recipe to cook in a crock-pot or slow cooker. Just set it and forget about it!
And the leftover sauce will stay fresh in the refrigerator for months or, if you're really handy, can the sauce in glass jars and they'll keep in the pantry indefinitely.
I like always having a jar of this barbecue sauce in the refrigerator, because my whole family LOVES using it on all sorts of foods.

Cheryl
About how many pints for canning does this recipe make?
Karrie
Hi Cheryl, a pint mason jar should hold 2 cups, so the recipe should make around 5 pints (or 10 cups).
Elly

Tried this sauce over the weekend and it was a hit at our cookout! Crockpot made it so easy and will be making again. Thanks for the recipe.
Christy
Could you alter this to be made in the instant pot to cut the cooking time?
Karrie
Hi Christy, I've never tried cooking it in an instant pot, so not sure if it would work or not.
