How to Make Slow Cooker Kielbasa Bites with Brown Sugar and Mustard Sauce Recipe
Step 1: Prepare the kielbasa
Start by slicing your kielbasa sausage into bite-sized pieces. This makes them perfect for snacking and ensures the sauce can coat each piece evenly. Place the sliced kielbasa into your slow cooker, ready for the magic that’s about to happen.
Step 2: Whisk together the sauce
In a medium bowl, combine the brown sugar, Dijon mustard, ketchup, apple cider vinegar, Worcestershire sauce, garlic powder, smoked paprika, salt, and pepper. Whisk everything together until the ingredients are fully blended, creating a rich sauce that’s bursting with flavor.
Step 3: Combine sausage and sauce
Pour the sauce over the sliced kielbasa in the slow cooker, then give it a good stir. Make sure every piece of sausage is nicely coated with the sauce, ensuring each bite is packed with that irresistible sweet and tangy goodness.
Step 4: Slow cook the kielbasa bites
Cover the slow cooker and cook on low for 3 to 4 hours or on high for 1.5 to 2 hours. The slow cooking not only tenderizes the sausage but also thickens the sauce to a luscious consistency. Stir occasionally if you can, just to make sure everything cooks evenly and the flavors meld beautifully.
Step 5: Serve and enjoy
Once the sauce is glossy and thick and the kielbasa bites are tender, it’s time to serve. Transfer the bites to a serving dish with some toothpicks and watch them disappear during your next party or casual get-together!

Garnishes
A little garnish goes a long way in making these kielbasa bites pop visually and flavor-wise. Try sprinkling chopped fresh parsley or chives over the top for a bright pop of green and fresh herbaceous notes. A light dusting of cracked black pepper or a drizzle of extra Dijon mustard on the side also works wonders.
Side Dishes
These bites shine on their own or alongside simple sides. Think crunchy pretzel sticks, soft dinner rolls, or even a crisp garden salad to balance the richness. On game day, they’re fantastic with classic potato chips or even a creamy coleslaw that adds crunch and coolness.

For party trays, place them in small bowls surrounded by colorful veggies for a stunning appetizer display.
Make Ahead and Storage
Storing Leftovers
Leftover kielbasa bites keep beautifully in an airtight container in the refrigerator for up to 3 days. The sauce continues to soak into the sausage, making them even more flavorful the next day.
Freezing
To freeze, place the cooled kielbasa bites and sauce in a freezer-safe bag or container. They’ll keep for up to 2 months. Thaw overnight in the fridge before reheating for best results.
Reheating
Reheat leftovers gently in a saucepan over low heat, stirring occasionally, or use the microwave in short bursts to avoid drying out the sausage. Adding a splash of water or extra mustard can refresh the sauce if it’s thickened too much in storage.
FAQs
Can I use a different type of sausage for this recipe?
Absolutely! While kielbasa is traditional and has a wonderful smoky flavor, you can substitute with smoked sausage or even spicy Italian sausage for a twist. Just make sure to cut it into similar bite-sized pieces for even cooking.
Is it necessary to use a slow cooker?
The slow cooker is key for tenderizing the sausage and melding the sauce flavors slowly. However, you can make this on the stovetop in a saucepan over low heat for about 30 minutes, stirring occasionally, though the texture will be a bit different.
Can I make this recipe gluten-free?
Yes! Just double-check that your Worcestershire sauce and other condiments are gluten-free, as some brands may contain gluten. The rest of the ingredients are naturally gluten-free.
How sweet is the sauce?
The sauce has a nicely balanced sweetness that’s not overpowering thanks to the tangy mustard and vinegar. If you prefer it less sweet, feel free to reduce the brown sugar slightly.
