Why You’ll Love This Slow Cooker Sausage and Sauerkraut Recipe

What really gets me excited about this Slow Cooker Sausage and Sauerkraut Recipe is the way the flavors marry while it cooks low and slow.

Then, the burst of sweetness from the apple is an unexpected but wonderful touch I always look forward to. It’s like a cozy blend of hearty and fresh that fills every bite with so much character.

These ingredients are pretty straightforward, but each one plays an essential role in making this dish so tasty and satisfying. From the smoky kielbasa to the tangy sauerkraut and the zesty Dijon mustard, every item brings texture, color, or flavor that truly shines after slow cooking.

Smoked Kielbasa or Sausage: Offers a hearty, smoky flavor and protein-packed base for the dish.
Sauerkraut (with juice): Adds tanginess and moisture while blending perfectly with the sausage.
Small Onion, diced: Provides subtle sweetness and depth to the overall flavor profile.
Large Apple, diced: Brings a natural sweetness that balances the sour kraut.
Dijon Mustard: Adds a gentle tang and complexity to the sauce.
Caraway or Dill Seeds: Introduces an herbal, slightly nutty aroma traditional to this dish.
Salt & Pepper: Essential to season and enhance all the flavors.
Low-Sodium Chicken Broth or Water: Used if you’re making the Instant Pot version to maintain moisture without overpowering.
Oil: For browning the sausage in the Instant Pot version to deepen flavor.

Directions

Step 1: Combine the smoked kielbasa (cut into 1-inch pieces), sauerkraut with its juice, diced onion, diced apple, Dijon mustard, caraway or dill seeds, and salt and pepper in your slow cooker. Stir everything together gently to mix the flavors before cooking.

Step 2: Set the slow cooker to HIGH and cook for 2 to 3 hours or on LOW for 4 to 6 hours. Give it a quick stir halfway through if you can, but otherwise let the slow cooker do its magic as the aromas fill your kitchen.

Step 3: If you prefer the Instant Pot method, start by turning it to sauté mode. Add a tablespoon of oil, then brown the sausage pieces for 5 to 7 minutes until they have a nice caramelized color on all sides. You may need to do this in batches to avoid overcrowding.

Step 4: Remove the browned sausage from the Instant Pot and set it aside. Pour 1 cup of chicken broth or water into the bottom of the pot to prevent burning during pressure cooking.

Step 5: Layer the sauerkraut, diced apple, and Dijon mustard on the bottom of the Instant Pot in a single layer.

Step 6: Place the browned sausage chunks on top of the sauerkraut layer. This layering helps infuse all the flavors during cooking.

Step 7: Seal the Instant Pot lid and cook on high pressure for 15 minutes. Once done, allow the pressure to release naturally for the best texture and flavor.

Servings and Timing

This Slow Cooker Sausage and Sauerkraut Recipe serves about 6 people, making it perfect for families or small gatherings. The prep time is incredibly short—only around 10 minutes to chop and combine everything. Cooking takes approximately 3 hours in the slow cooker or just under 30 minutes with the Instant Pot method (including prep and sauteing). There’s no additional resting time needed, so you can serve it right away for best freshness and warmth.

When it comes to serving this dish, I love pairing it with simple, complementary sides that balance the tangy and smoky flavors. Creamy mashed potatoes or buttery spaetzle work wonderfully to soak up all those delicious juices. For a lighter side, I often serve a crisp green salad or roasted seasonal vegetables to add freshness and color to the plate.

To really elevate the presentation, I garnish with a sprinkle of fresh parsley or chives, which adds a pop of vibrant green and a fresh note to each serving. I also like to offer a dash of whole-grain mustard on the side for anyone who wants a bit more kick. This dish is best enjoyed warm—right from the crockpot or Instant Pot while the flavors are at their peak. It’s fantastic for cozy family dinners, casual parties, or even festive holiday spreads when you want something comforting without fuss.

As for drinks, I reach for an earthy German-style beer like a Dortmunder or a medium-bodied dry Riesling, both of which complement the smoky and tangy notes brilliantly. If you prefer non-alcoholic options, a sparkling apple cider or a crisp ginger ale provides a refreshing contrast and a little sweetness that plays well with the sauerkraut and sausage.

Variations

I love how versatile this Slow Cooker Sausage and Sauerkraut Recipe is. For example, you can swap the smoked kielbasa for bratwurst, Polish sausage, or even a spicy Andouille sausage to tailor the flavor to your preference. For a leaner option, turkey or chicken sausage works beautifully too, maintaining protein without overpowering the dish.

If you’re feeding guests with dietary restrictions, making this dish gluten-free is easy—just double-check your sausage ingredients and Dijon mustard to ensure they’re gluten-free. For a vegan twist, you can skip the sausage entirely and instead use smoked tempeh or seitan with vegan sauerkraut and vegetable broth, creating a delicious plant-based version that still feels hearty and satisfying.

For a flavor boost, I sometimes add a splash of apple cider vinegar or a small teaspoon of smoked paprika. If you want to switch up cooking methods, you could even braise this mixture on the stovetop in a heavy pot over low heat for 45 minutes to an hour, stirring occasionally to prevent sticking and develop a beautiful crust on the sausage.

Storage and Reheating

Storing Leftovers

Once cooled to room temperature, I transfer leftovers to airtight containers for storing in the refrigerator. Using glass containers with tight-fitting lids works best to keep the dish fresh and prevent odors from spreading. Leftovers will keep well for 3 to 4 days, giving you easy, flavorful meals throughout the week.

Freezing

This recipe freezes nicely if you want to save some for later. I portion the cooled dish into freezer-safe containers or heavy-duty zip-top bags, making sure to press out as much air as possible. Labeling with the date helps keep track. It will maintain great quality for up to 3 months in the freezer. When ready to enjoy, thaw it in the refrigerator overnight before reheating.

Reheating

To reheat, I prefer warming it gently on the stove over medium heat, stirring occasionally to prevent sticking and to help the flavors come back to life. You can add a splash of water or broth if it seems a bit dry. Microwaving works fine too, but I recommend covering it loosely and heating in short intervals, stirring in between for even warming. Avoid reheating at very high heat or too quickly, as it can dry out the sausage and toughen the sauerkraut.

FAQs

Can I use fresh cabbage instead of sauerkraut?

You can, but the flavor and texture will be quite different. Sauerkraut provides a unique tang and moisture that fresh cabbage doesn’t. If you use fresh cabbage, I recommend sautéing it first and adding vinegar or lemon juice to mimic the sourness.

Is it necessary to brown the sausage first?

Browning the sausage before slow cooking isn’t required but it adds wonderful depth and a caramelized flavor that takes this dish to the next level. For the slow cooker, you can skip it, but for the Instant Pot method, it really makes a difference.

Can I prepare this recipe ahead of time?

Yes! You can assemble everything in the slow cooker insert the night before, cover, and refrigerate. When ready, simply turn on the cooker and increase cook time slightly to ensure it cooks through properly.

What sides do you recommend serving with this dish?

I personally love serving it with mashed potatoes, roasted root vegetables, or spaetzle. A crisp green salad also pairs nicely to add freshness and balance.

Can I reduce the sodium in this recipe?

Definitely. Using low-sodium sauerkraut or rinsing regular sauerkraut slightly helps, and choosing low-sodium sausage or chicken broth reduces salt. You can always adjust salt to taste at the end of cooking.
