Add the meatballs to the crockpot. You don’t even need to thaw them. Just open the bag and pour them right in.
Mix the sauce. In a small bowl (or directly in the crockpot) stir together the BBQ sauce, cranberry sauce, apple cider vinegar, and Worcestershire sauce until everything is well combined.
Pour the sauce over the meatballs. Use a spatula or spoon to gently stir and coat the meatballs with that delicious cranberry BBQ mixture.
Cover and cook on high for 3 hours. You’ll know they’re ready when the sauce is bubbly and the meatballs are hot all the way through.
Stir once more before serving. If you want to make it look fancy, sprinkle some chopped fresh parsley over the top for color.
Notes
If you're prepping ahead for a party or dinner, you can mix the sauce ingredients in a jar or airtight container and keep it in the fridge for up to 3 days.
You can also assemble everything in the Crockpot insert and keep it in the fridge (covered) overnight, just pop it into the base in the morning and let it cook.
The “keep warm” setting is your best friend here. Once cooked, these meatballs will stay warm and ready to serve for hours, just give them a little stir now and then so the sauce stays evenly distributed.
A few variations...
Spicy twist: Add a few dashes of hot sauce or a pinch of red pepper flakes to the sauce for a bit of heat.
Homemade meatballs: You can use homemade meatballs if you’ve got some on hand, just make sure they’re fully cooked before adding to the Crockpot.
No cranberry? If you’re out of jellied cranberry sauce, you can sub in a cranberry jelly or even whole cranberry sauce. It’ll change the texture a little, but still taste great.
Add some tang: A spoonful of Dijon mustard adds another layer of flavor if you want to experiment.
