Ingredients (And Why Each One Matters)
3 pounds kielbasa sausage, sliced into ½-inch coins
The heart of the dish. Kielbasa is a fully cooked Polish-style smoked sausage known for its rich, savory flavor and firm texture. It holds up beautifully in the slow cooker without drying out and provides that signature smoky bite that balances the sweetness of the glaze.
2 cups packed light brown sugar
This is what creates the iconic sticky caramelized glaze. The molasses in brown sugar adds depth and warmth, transforming into a thick, glossy coating as it cooks and finishes under the broiler.
1 cup ketchup
Ketchup brings tangy sweetness and tomato richness. It acts as the base of the sauce, helping dissolve the sugar and create a smooth glaze that clings to every slice.
¼ cup yellow mustard
Mustard adds sharpness and acidity. It cuts through the sweetness and enhances the savory notes of the sausage, keeping the dish from becoming overly sugary.
Step-by-Step Instructions
1. Prepare for Easy Cleanup
Line a large rimmed baking sheet with aluminum foil. This will be used later for broiling and caramelizing the kielbasa. Set aside.
2. Slice the Kielbasa
Cut the sausage into ½-inch thick coins, keeping the slices uniform. Even cuts ensure consistent heating and caramelization.
3. Mix the Sticky Brown Sugar Glaze
In a medium bowl, whisk together:
Brown sugar
Ketchup
Yellow mustard
Whisk until the mixture is smooth and glossy with no visible dry sugar. The sauce should be thick but pourable.
4. Slow Cook to Perfection
Place the sliced kielbasa in a 5- to 6-quart slow cooker. Pour the glaze evenly over the top and gently stir to coat every piece.
Cook:
LOW for 4–5 hours, or
HIGH for 2–2½ hours
Stir once or twice during cooking to ensure even coating. The sauce will bubble and thicken as it cooks.
5. Broil for Caramelized Edges
Preheat your broiler to high and position a rack in the upper third of your oven.
Using a slotted spoon, transfer the glazed kielbasa onto the foil-lined baking sheet in a mostly single layer. Spoon a little extra sauce over the top.
Broil for 3–6 minutes, watching carefully. The glaze should bubble, darken slightly, and form those irresistible sticky edges. Rotate the pan if needed for even browning.
⚠️ Do not walk away—brown sugar can burn quickly.
6. Rest & Serve
Let the kielbasa rest for 5 minutes. The glaze will thicken further, creating that signature glossy finish.
Serve warm with toothpicks for easy grabbing.
