Slow Cooker Sweet and Sour Kielbasa with Pineapple
Prep Time: 5 minutes | Cook Time: 4-5 hours on LOW or 2-2.5 hours on HIGH | Total Time:Approximately 4-5 hours
Yield: 6 servings
Ingredients
-
2 pounds smoked kielbasa or Polish sausage, sliced into ½-inch rounds
-
1 can (20 ounces) pineapple chunks in juice, undrained
-
1 cup sweet and sour sauce (bottled, store-bought)
-
½ cup ketchup
Instructions
1. Add the Kielbasa:
Place the sliced kielbasa in an even layer in the bottom of a 4- to 6-quart slow cooker.
2. Add the Pineapple:
Open the can of pineapple chunks and pour the pineapple and all of its juice evenly over the sliced kielbasa.
3. Make the Sauce:
In a small bowl or measuring cup, whisk together the sweet and sour sauce and ketchup until smooth and fully combined.
4. Pour Over the Ingredients:
Pour the sweet and sour sauce mixture over the kielbasa and pineapple, using a spatula to scrape out every bit. Gently stir just enough to coat the sausage and pineapple without splashing.
5. Cook:
Cover and cook on LOW for 4 to 5 hours, or on HIGH for 2 to 2½ hours, until the sausage is heated through and the sauce is bubbly and slightly thickened.
6. Serve:
Taste and adjust if needed, adding a spoonful more ketchup for extra tang or a splash of pineapple juice or water if the sauce is thicker than desired. Switch the slow cooker to WARM for serving, and stir gently before ladling the sausage and pineapple, along with plenty of sauce, over rice, noodles, or into serving bowls.
Recipe Notes & Pro Tips
Smoked Kielbasa: Smoked kielbasa or Polish sausage is ideal for this recipe. It is already fully cooked, so the slow cooker simply warms it through and infuses it with flavor. Look for good-quality sausage with a natural smoke flavor. Turkey or chicken kielbasa can be substituted for a lighter option.
Pineapple in Juice vs. Syrup: Use pineapple chunks packed in their own juice (not heavy syrup). The natural juice adds sweetness and acidity without being cloying. The juice also helps thin the sauce to the perfect consistency.
Sweet and Sour Sauce: Bottled sweet and sour sauce is a convenient shortcut. Look for a good-quality brand. For a homemade version, combine ½ cup of sugar, ¼ cup of vinegar, ¼ cup of ketchup, and 1 tablespoon of soy sauce.
Ketchup Adds Tang and Body: The ketchup adds a rich tomato flavor, extra tang, and helps thicken the sauce. Do not skip it.
Thicker Sauce: If you prefer a thicker, stickier glaze, remove the lid during the last 30 minutes of cooking to allow the sauce to reduce slightly.
Add Vegetables (Optional): For extra color and flavor, add 1 cup of bell pepper strips (red, green, or yellow) or 1 cup of chopped onion to the slow cooker along with the kielbasa. The vegetables will soften and absorb the sauce.
Variations
Spicy Sweet and Sour Kielbasa: Add ½ teaspoon of red pepper flakes, 1 teaspoon of sriracha, or 2 tablespoons of sambal oelek to the sauce mixture. The heat balances the sweetness beautifully.
Hawaiian Kielbasa: Add 1 cup of chopped bell peppers (red and green) and ½ cup of chopped onion to the slow cooker. Serve over coconut rice for a tropical meal.
Teriyaki Kielbasa: Substitute the sweet and sour sauce with 1 cup of teriyaki sauce. Omit the ketchup. The teriyaki adds savory umami depth.
BBQ Kielbasa with Pineapple: Substitute the sweet and sour sauce with 1 cup of barbecue sauce. The BBQ adds smokiness and depth.
Honey Soy Kielbasa: Substitute the sweet and sour sauce with ½ cup of honey and ½ cup of soy sauce. Omit the ketchup. Add 1 teaspoon of garlic powder and 1 teaspoon of ground ginger.
Kielbasa Bites Appetizer: Cut the kielbasa into smaller ¼-inch slices and serve the finished dish with toothpicks as an appetizer. The slow cooker can stay on WARM for hours, making it perfect for parties.

To reheat, place individual portions in the microwave in 60-second bursts, or warm the entire dish in a covered skillet over medium-low heat, adding a splash of water or pineapple juice if the sauce has thickened too much.
This dish freezes well for up to 3 months. Cool completely, then transfer to freezer-safe containers. Thaw overnight in the refrigerator before reheating.
Why This Recipe Works
The combination of smoked kielbasa, pineapple, sweet and sour sauce, and ketchup creates a dish that is sweet, tangy, savory, and deeply satisfying. The kielbasa provides smoky, savory richness. The pineapple adds natural sweetness, acidity, and a tropical brightness. The sweet and sour sauce brings the signature tangy-sweet flavor. The ketchup adds a rich tomato note and helps thicken the sauce.
The slow cooker is the perfect vessel for this dish because it allows the kielbasa to heat through gently while the pineapple and sauce meld into a glossy, flavorful glaze. The pineapple juice and the sauce combine to create a cooking liquid that keeps the sausage moist and infuses it with flavor.
This recipe is proof that you do not need a long list of ingredients or complicated techniques to make a delicious, crowd-pleasing dish. With four simple ingredients and a slow cooker, you can create sweet and sour kielbasa with pineapple that is perfect for parties, potlucks, or a quick weeknight dinner. Serve it over rice, and watch it disappear.
