Sausage and Sauerkraut Ingredients
- Sauerkraut, rinsed and drained — Rinsing removes excess brine and reduces the sharpness, giving you a mellower, more balanced base for the dish.
- Caraway seeds (optional) — A classic pairing with sauerkraut, these seeds lend a subtle earthy, slightly anise-like flavor that enhances the overall complexity.
- Brown sugar — Just a touch softens the tartness of the sauerkraut and ties the sweet-savory flavors together beautifully.
- Apple, diced — Adds natural sweetness and a slight brightness that cuts through the richness of the meat.
- Cooking spray — Used to grease the baking dish so nothing sticks and cleanup stays easy.
- Bacon — Renders down into the mixture, adding smoky depth and a savory backbone to the entire dish.
- Onion, chopped — Cooked until golden, onion brings a subtle sweetness and aromatic richness that rounds out the flavors.
- Kielbasa sausage — The star of the show. Smoky, garlicky, and hearty, kielbasa holds up beautifully during the long bake and soaks in all the surrounding flavors.
Step-By-Step Direction
Step 1: Gather all of your ingredients and have them ready to go.
Step 5: In a large saucepan over medium-low heat, combine the sauerkraut, caraway seeds, brown sugar, and chopped apple. Bring the mixture to a gentle simmer, then reduce the heat to low and cook for about 2 hours, stirring occasionally.
Step 3: Preheat your oven to 325°F (165°C) and lightly grease a 9×13-inch baking dish. Meanwhile, cook the bacon and onion in a skillet over medium heat until the bacon is almost crispy and the onion is lightly browned, about 10 minutes. Stir the bacon and onion mixture into the cooked sauerkraut.
Step 4: Using the same skillet and the remaining bacon grease, brown the kielbasa for 10–15 minutes, or until lightly browned on all sides. Add the sausage to the sauerkraut mixture and stir everything together.
Step 5: Transfer the mixture to the prepared baking dish and spread it out evenly. Bake for about 1 hour, or until the casserole is hot, bubbly, and heated through.
Tips for the Best Results
Don’t skip rinsing the sauerkraut — it prevents the dish from becoming overly salty or too sharp in flavor.
Use a tart apple variety like Granny Smith for contrast, or a sweeter one like Fuji if you prefer a milder flavor.
Sear the kielbasa well — that browned crust adds a layer of flavor you simply can’t skip.
Cook the bacon and onion low and slow — rushing this step means missing out on the caramelization that builds the dish’s savory base.
Don’t raise the oven temperature — the lower heat is intentional and keeps the sauerkraut from drying out while allowing the flavors to deepen.
Storage
Refrigerator: Let leftovers cool completely before transferring to an airtight container. The dish keeps well in the fridge for up to 4 days. Reheat in the microwave or in a covered skillet over low heat with a small splash of water or broth to loosen it up.
Freezer: This recipe freezes beautifully. Portion it into freezer-safe containers and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating. The flavors actually deepen after freezing, making it an excellent make-ahead meal.
Sausage and Sauerkraut
Ingredients
- 2 pounds sauerkraut rinsed and drained
- 1 tablespoon caraway seeds Optional
- ¼ cup brown sugar
- 1 apple diced
- cooking spray
- ½ pound bacon cut into 1-inch pieces
- 1 large onion chopped
- 1 ½ pounds kielbasa sausage cut into 1-inch thick slices
Instructions
- Gather all your ingredients and prep everything before you begin — dice the apple, chop the onion, and slice the kielbasa if desired.
- Add the sauerkraut, caraway seeds, brown sugar, and diced apple to a large saucepan over medium-low heat. Bring to a gentle simmer, then reduce heat to low. Cook for 2 hours, stirring occasionally, until softened and flavors have melded.
- Preheat your oven to 325°F (165°C). Grease a 9×13-inch baking dish with cooking spray. In a skillet over medium heat, cook the bacon and chopped onion together for about 10 minutes until the bacon is nearly crispy and the onion is golden. Stir the bacon and onion mixture into the sauerkraut.
- In the same skillet using the remaining bacon grease, cook the kielbasa sausage over medium heat for 10 to 15 minutes, turning occasionally, until browned on the outside. Stir the browned kielbasa into the sauerkraut mixture.
- Spoon the entire sauerkraut and sausage mixture into the prepared baking dish. Bake uncovered in the preheated oven for about 1 hour, until the dish is hot, bubbling, and slightly caramelized around the edges. Serve warm.
Notes
- Rinsing the sauerkraut before cooking is key — it cuts the sharpness and prevents the dish from being too salty.
- For extra depth of flavor, splash in a few tablespoons of lager or dark beer while the sauerkraut simmers.
- Leftovers store in an airtight container in the refrigerator for up to 4 days, or freeze for up to 3 months.
- This dish tastes even better the next day once all the flavors have had time to develop overnight.
- Serve alongside mashed potatoes, buttered egg noodles, or crusty rye bread for a complete meal.
