Slow Cooker BBQ Sauce

This slow cooker BBQ sauce is sweet, tangy, and incredibly delicious. It’s the perfect condiment to get cooking in your slow cooker.

Slow Cooker BBQ Sauce

As I mention a lot, the slow cooker is ideal for making sauces and condiments as the long cooking time allows for flavors to intensify, creating that condiment everyone likes.

Making BBQ sauce from scratch is perfect, as you can control the ingredients and flavors. You can make it exactly how you like it, and you know all the ingredients that have gone into it.

A BBQ sauce is so versatile and will come in handy with so many different recipes. For example, it’s excellent as a sauce on a pizza. It is also fantastic as a marinade on some chicken or beef. I love to mix it through some pulled pork.

Tweaking the BBQ Sauce Recipe

There are so many different tweaks that you can do for this BBQ sauce.

Adding liquid smoke to the mixture will create a new level of flavor. It’s ideal if you love your sauce to have a bit of a smoky hint to it. Be careful not to add too much as it will ruin the taste of the sauce.

To turn this into a honey BBQ sauce, simply replace half of the brown sugar with honey. For a stronger honey flavor, you can replace all of the brown sugar.

Reducing the quantity of sugar is a great way to add a bit of zest back to the BBQ sauce. I recommend reducing the brown sugar and treacle by roughly half to get the sauce to be less sweet.

I have listed a few more examples in the cooking tips further down the page that you should check out.

How Long will the BBQ Sauce Last

This slow cooker BBQ sauce will keep for a couple of weeks stored covered in the refrigerator. To have it keep for longer, you will need to look at sealing the jar correctly.

If you’re going to store the BBQ sauce in a sealed jar, then you might want to double or triple the recipe, so you get more out of the one batch. I found this recipe made enough for a couple of weeks in our large household.

Recipe Tips

  • If you love a smoky flavor in your BBQ Sauce, then try adding a couple of drops of liquid smoke. This liquid will add a ton of flavor to the sauce.
  • You can also try swapping the brown sugar for honey instead, or you can do 50/50. This alteration will give you a honey BBQ sauce that is delicious.
  • To get a perfectly smooth BBQ sauce, you will need to push it through a sieve. Doing this will remove any lumps and leave you with a silky-smooth sauce.
  • The type of apple that you use should be a cooking apple such as granny smith. With that said, most variations of apple will still work fine.
  • Treacle can be replaced with regular molasses. However, do not use blackstrap molasses as it can be quite bitter.
  • You can reduce the sugar slightly if you prefer your BBQ sauce to be tangy rather than sweet.

Note: I use a 5.5L (6 Quart) slow cooker for all the recipes that I have on this website unless specified. If you have a smaller or larger slow cooker, then you might need to adjust the ingredients.

    Hi there, do I add the pork at the beginning of the recipe too in order to do a slow cooker bbq pulled pork? Thanks!

      Hi Carrie, adding the pork at the start will work great for pulled pork. You may need to skim excess oil off the top of the sauce before you go to serve.
