What is Kielbasa and Sauerkraut?
Kielbasa is a traditional Polish smoked sausage, typically made from pork, beef, or a combination, seasoned and cured for a distinctive flavor and texture. Sauerkraut is finely cut cabbage that’s been fermented by lactic acid bacteria, resulting in a tart, crunchy, and aromatic side.
When cooked together, the smokiness of the sausage melds with the acidic brightness of the sauerkraut, creating a dish that’s as beloved at family gatherings as it is for weeknight dinners.
Ingredients You’ll Need
- Kielbasa: Smoked, fully cooked Polish sausage. Chop into rounds or thick chunks.
- Sauerkraut: Jarred, canned, or refrigerated. Rinse for milder flavor or use as-is for more tang.
- Onion: Yellow or sweet onion for an aromatic base.
- Butter or Oil: For sautéing and adding richness. Olive oil works well, but butter gives more flavor.
- Optional: Brown sugar, caraway seeds, spicy brown or Dijon mustard, apples, potatoes, apple juice or chicken broth, garlic, and black pepper.

Step-by-Step: How to Make Kielbasa and Sauerkraut
1. Prepare the Sauerkraut
- Drain the sauerkraut well, using a mesh strainer.
- For milder flavor, rinse sauerkraut with cool water and squeeze out excess liquid. For bold, briny notes, skip rinsing.
2. Slice the Kielbasa
- Cut kielbasa into 1-inch chunks or thick coins, depending on your preference.
- If sausage is uncooked, cook fully before proceeding. Most grocery kielbasa is smoked and precooked.
3. Sauté the Aromatics
- Heat butter or oil in a large skillet over medium-high heat.
- Add chopped onions and sauté until soft and golden, about 5 minutes.
4. Brown the Kielbasa
- Add kielbasa slices to the skillet and cook until browned on all sides, about 5–7 minutes.
- Transfer sausage to a plate. Leave rendered fat and onions in the pan for flavor.
5. Add Sauerkraut and Seasonings
- Add drained sauerkraut to the skillet with onions and rendered fat.
- Season with black pepper, caraway seeds, brown sugar, mustard, or other desired flavorings.
- If using, add diced potatoes or apples at this stage.
6. Combine & Simmer
- Return browned kielbasa to the skillet, nestling it into the sauerkraut.
- Pour in a splash of liquid (such as chicken broth or apple juice) for moisture and to develop more flavor.
- Cover and simmer on low heat for 10–15 minutes, until everything is heated through and flavors meld.
Alternate Cooking Methods
- Oven: Layer ingredients in a baking dish, cover tightly with foil, and bake at 350°F for 40–45 minutes.
- Slow Cooker: Layer diced onion, sauerkraut, and kielbasa in a slow cooker; drizzle with your liquid and seasonings. Cook on LOW for 4–6 hours or on HIGH for 2–4 hours for ultra-tender results.
- Sheet Pan: For an easy one-pan meal, toss everything together on a sheet pan and roast at 400°F for 30–35 minutes.
- Air Fryer: Cook sausage and sauerkraut in an air fryer-safe dish at 375°F for 15–18 minutes, stirring halfway.
Flavorful Variations and Additions
- With Potatoes: Dice Yukon gold or red potatoes and cook them with their skins on for extra heartiness.
- With Apples: Add tart apples (like Granny Smith) for a subtle sweetness that balances the sauerkraut’s tang.
- With Mustard: Stir in a couple tablespoons of spicy brown mustard or Dijon for depth and zing.
- With Brown Sugar: Sprinkle brown sugar for a touch of caramel-like sweetness.
- With Beer: Swap some or all of the broth/juice for a malty German beer for authentic flavor.
- Spicy Kick: Add red pepper flakes or diced hot peppers for heat.
Expert Tips for Best Results
- Don’t Skip Searing: Browning the sausage unlocks the best savory flavor and caramelizes the outer layer.
- Adjust Tanginess: Rinse and drain sauerkraut for a milder dish or leave as-is for full flavor. Taste and rinse in stages if unsure.
- Add Moisture as Needed: If the pan mixture dries out, splash in a bit more broth or water to keep everything juicy.
- Layer Flavors: Each added ingredient, from onions to apples to caraway seed, builds a more complex flavor profile.
- Leftovers: Flavor improves as leftovers sit in the fridge. Reheat gently on the stove or in a low oven.
Serving Suggestions
- With Rye Bread: Serve alongside hearty rye bread or crusty rolls for a classic touch.
- With Roasted Potatoes: Complement with another side of crispy roasted potatoes or German-style potato salad.
- With Mustard: Offer grainy or spicy mustards at the table for dipping sausage bites.
- For a Full Meal: Add a green salad or simple steamed vegetables to round out the dinner.

Frequently Asked Questions (FAQs)
Can I use uncooked/unsmoked sausage?
Yes. If using raw sausage instead of smoked kielbasa, ensure you fully cook the sausage before combining it with sauerkraut to avoid foodborne illness.
Is it necessary to rinse the sauerkraut?
This depends entirely on your taste preference. Rinsing sauerkraut reduces its sharp, acidic edge and some sodium, yielding a milder dish. For a punchier, more fermented flavor, skip rinsing.
Can I substitute other sausages for kielbasa?
Yes, smoked sausage, bratwurst, or even plant-based sausage alternatives can be used in place of traditional kielbasa.
How do I make it less sour or less salty?
Rinsing sauerkraut and draining it well before cooking reduces both tang and saltiness. Adding a little brown sugar or apple juice helps mellow the acidity further.
What’s the difference between jarred, canned, and fresh sauerkraut?
Fresh or refrigerated sauerkraut (often in the deli section) tends to be crunchier and have more complex flavors, while canned or jarred is usually softer and more mellow. Any version works for this dish.
How do I prevent the dish from drying out?
Add small amounts of broth, water, or apple juice periodically while simmering, especially if you notice the mixture looking dry. Covering the dish during cooking also helps retain moisture.
Are there gluten-free options?
Most kielbasa and sauerkraut are naturally gluten-free, but always check labels if you have dietary restrictions, especially for sausages containing fillers or sauces that may have gluten.
Pro Tips for Customizing Your Dish
- To Sweeten: Add extra brown sugar or diced apples at the beginning of cooking.
- To Make It Spicy: Stir in a pinch of crushed red pepper flakes, or add sliced hot peppers.
- To Boost Nutrition: Include diced carrots, sweet bell peppers, or even kale for extra color and vitamins.
- To Intensify Smokiness: Add a splash of smoked paprika or use double-smoked kielbasa when available.
