My Story With This Recipe
I first made these kielbasa bites for a family gathering when I needed something easy that could sit out and stay warm. I had kielbasa in the fridge and some apple butter in the pantry, so I mixed them together with barbecue sauce and hoped for the best.
The smell filled the kitchen after just an hour, and people started sneaking bites before dinner. By the end of the night, the crockpot was empty. Since then, this has become one of those dependable recipes I make whenever I need something simple that everyone enjoys.

Recipe
Step 1: Mix the Sauce
In a mixing bowl, combine 1 cup apple butter, 1 cup barbecue sauce, 1 tablespoon Dijon mustard, and 1 tablespoon brown sugar. Stir until smooth and fully blended.

Step 2: Add Kielbasa to Crockpot
Place 2 pounds sliced kielbasa rounds into the black oval crockpot. Pour the prepared apple barbecue sauce over the kielbasa.

Step 3: Stir Everything Together
Stir the sliced kielbasa and sauce until all pieces are evenly coated.

Step 4: Slow Cook
Cover and cook on LOW for 2 to 3 hours or HIGH for 1 to 1½ hours, until the kielbasa is heated through and the sauce is thick and glossy.
Step 5: Serve
Stir once more and transfer the kielbasa bites to a round serving bowl. Spoon extra sauce over the top before serving.

Why This Recipe Works
The apple butter contains natural fruit sugars that slowly caramelize during cooking. Barbecue sauce brings smoky and tangy flavors, while mustard adds a little sharpness to balance the sweetness. The kielbasa already has plenty of flavor, so it absorbs the sauce while staying juicy and tender.
Common Mistakes
- Cooking too long can make the sauce overly thick.
- Using very thin barbecue sauce can create a watery result.
- Forgetting to stir can leave some pieces less coated.
- Slicing the kielbasa too thin may cause pieces to break apart.
- Cooking on high too long can make the sauce stick to the sides.
