Essential Ingredients for Your Perfect Kielbasa and Sauerkraut

Crafting this delicious Crockpot Kielbasa and Sauerkraut requires only a few straightforward ingredients, each playing a crucial role in building the dish’s signature flavor profile. Here’s a closer look at what you’ll need to create this epic meal. Remember, specific measurements and detailed step-by-step instructions are included in the printable recipe card at the end of this post.

• Bacon: This isn’t just an optional extra; bacon adds an incredible depth of smoky, savory flavor that elevates the entire dish. While you could omit it, we highly recommend including it for that extra layer of deliciousness.
• Medium Onion: Sliced onions sautéed until translucent provide a subtle sweetness and aromatic foundation that beautifully complements the other ingredients.
• Sauerkraut: The star of the show! You can use either bagged or jarred sauerkraut, depending on your preference and what’s available. Both work wonderfully, just be sure to drain it well if you prefer a less tart outcome.
• Light Brown Sugar: A touch of brown sugar is key to balancing the natural tartness of the sauerkraut, adding a gentle sweetness that rounds out the flavors without making the dish overtly sweet.
• Kielbasa: We opt for fully cooked smoked kielbasa, cut into bite-sized pieces. This versatile sausage allows for easy preparation and quick flavor infusion. Feel free to experiment with different varieties like turkey sausage, traditional Polish sausage, pork sausage, or even a spicy jalapeño-flavored sausage for an extra kick!

Recommended Equipment for Effortless Cooking

While the ingredient list is short and sweet, having the right equipment makes this recipe even easier.

• Slow Cooker: A reliable slow cooker is indispensable for this recipe. We particularly recommend models with a digital timer that automatically switches to a “warm” setting once the cooking cycle is complete. This feature provides peace of mind, ensuring your dinner is perfectly cooked and ready when you are, without the risk of overcooking.
• Large Skillet or Saucepan: Essential for browning the bacon, sautéing onions, and searing the kielbasa before it goes into the slow cooker. This crucial step develops rich flavors through the Maillard reaction, adding complexity to the final dish.
• Sharp Knife and Cutting Board: For safely and efficiently slicing the onion and kielbasa.
• Paper Towels: For draining excess fat from the bacon and sautéed onions.

How to Master Kielbasa and Sauerkraut: Multiple Cooking Methods

This versatile dish can be prepared using several methods, each offering a slightly different texture and cooking experience. Here’s how to make your Kielbasa and Sauerkraut, no matter your preferred kitchen appliance.

Slow Cooker Method (Recommended for Best Flavor and Ease)

The slow cooker truly shines with this recipe, allowing flavors to meld beautifully over several hours.

1. Prepare Bacon and Onions: In a large saucepan or skillet, cook the bacon until it’s wonderfully crisp. Remove the cooked bacon and set it aside on a plate lined with paper towels to drain. Crumble it once cool.
2. Sauté Onions: Using the reserved bacon drippings in the same pan (this adds incredible flavor!), sauté the sliced medium onion until it becomes transparent and tender. Remove the onions and place them on paper towels to drain any excess fat.
3. Brown Kielbasa: While optional, briefly browning the kielbasa slices in the pan after the onions can add a deeper, caramelized flavor. Cut the kielbasa into ¾-inch thick slices and sear them for a few minutes until lightly browned on all sides.
4. Combine in Slow Cooker: Transfer the drained sauerkraut, sautéed onions, crumbled bacon, and browned kielbasa to your slow cooker. Add the light brown sugar, stirring gently to combine all ingredients.
5. Cook: Cover the slow cooker with its lid and cook on the “low” setting for 4 to 6 hours. The longer cooking time allows the flavors to fully develop and the ingredients to become tender.
6. Serve: Stir the mixture gently before serving. The rich aroma will tell you it’s ready!

Stovetop Method (Quick and Flavorful)

For a faster meal without sacrificing much flavor, the stovetop method is a fantastic alternative.

1. Prepare Bacon and Onions: Follow steps 1 and 2 from the slow cooker method for cooking bacon and sautéing onions.
2. Brown Kielbasa: In the same large skillet, cut kielbasa into desired lengths (¾-inch thick slices work well). Brown them evenly in a little olive oil or vegetable oil until nicely caramelized. Remove and set aside.
3. Heat Sauerkraut: Add the drained sauerkraut to the skillet. Heat it over medium heat until it’s warmed through, stirring occasionally.
4. Combine and Simmer: Return the browned kielbasa, sautéed onions, crumbled bacon, and brown sugar (if using) to the sauerkraut mixture in the skillet. Stir well, then cover and cook over low heat for 5-10 minutes, allowing the flavors to meld.

Sheet Pan Method (Easy Cleanup, Different Texture)

If you prefer roasted flavors and minimal dishes, the sheet pan method is a great choice.

1. Preheat Oven: Preheat your oven to 375°F (190°C). Lightly spray a large baking sheet with non-stick spray or line with parchment paper.
2. Roast Kielbasa: Arrange kielbasa pieces (cut into ¾-inch thick slices) in a single layer on the prepared baking sheet. Cook for 5-6 minutes, or until they are nicely browned and slightly crispy.
3. Add Sauerkraut: Remove the pan from the oven. Add the drained sauerkraut (and sautéed onions/bacon if you’ve prepared them) to the pan, spreading it around the kielbasa. Return to the oven and cook for another 8-10 minutes, until the sauerkraut is heated through and slightly caramelized.

Instant Pot Method (Fastest Option)

For those truly short on time, the Instant Pot can get this meal on the table in minutes, though it might result in a slightly softer texture for the kielbasa and sauerkraut.

1. Sauté Ingredients: Use the “Sauté” function on your Instant Pot. Cook bacon until crisp, remove and set aside. Sauté onions until transparent, remove. Brown kielbasa if desired.
2. Combine and Cook: Add drained sauerkraut, onions, bacon, brown sugar, and kielbasa to the Instant Pot. Add about ½ cup of liquid (water, chicken broth, or apple juice) to ensure proper pressurization.
3. Pressure Cook: Secure the lid and set the Instant Pot to “Manual” or “Pressure Cook” on high pressure for 9 minutes.
4. Release Pressure: Once cooking is complete, perform a quick release of pressure. Carefully open the lid, stir, and serve.

Preparation and Storage Tips

Planning ahead and knowing how to store leftovers can make mealtime even easier.

• Make Ahead: This Slow Cooker Kielbasa & Sauerkraut recipe cooks in 4 to 6 hours, making it an ideal candidate for preparing several hours before you plan to serve it. It only gets better as the flavors meld!
• Storage/Store Leftovers: Any leftover Kielbasa and Sauerkraut can be stored in an airtight container in the refrigerator for three to four days. It reheats beautifully.
• Freezing/How to Freeze: To freeze, allow the dish to cool completely. Divide the leftovers into individual or family-sized portions and place them in airtight, freezer-safe containers or heavy-duty freezer bags. Label each container with the date and recipe name. It will keep well in the freezer for up to three months. Be aware that freezing sauerkraut can slightly affect the texture and may reduce some of its living probiotic benefits, but the flavor will remain delicious.
• How to Reheat: Reheat defrosted or refrigerated leftovers on the stovetop over medium-low heat until warmed through, or in the microwave in short intervals, stirring occasionally, until hot.

Recipe Variations to Suit Your Taste

One of the best aspects of this Crockpot Kielbasa and Sauerkraut recipe is its adaptability. Feel free to customize it to your liking!

• Sausage Substitutions: While kielbasa is traditional, almost any smoked sausage will work wonderfully. Experiment with turkey kielbasa for a lighter option, traditional Polish sausage, or even a spicy Italian sausage if you crave a bolder flavor. Ensure the sausage is fully cooked for ease.
• Liquid Alternatives: For a different flavor profile, consider draining some of the sauerkraut liquid and replacing it with apple juice, apple cider, chicken broth, or even a light beer. These liquids can add sweetness, complexity, or a malty note, respectively.
• Delicious Additions:
  • Vegetables: Bulk up your meal by adding chopped bell peppers (red, yellow, or green), minced garlic, diced potatoes, or green beans to the slow cooker.
  • Sweetness Boost: If you enjoy a sweeter kraut, add more brown sugar, a touch of maple syrup, or chopped sweet apples (like Honeycrisp or Fuji) to the mix.
  • Herbs and Spices: Enhance the aromatic profile with caraway seeds (a classic pairing with sauerkraut), a pinch of dried dill, or a dash of ground black pepper. A bay leaf can also add subtle depth.
• Vegetarian + Vegan Option: Easily adapt this recipe by swapping traditional kielbasa and bacon for plant-based sausage and vegan bacon alternatives. Ensure all other ingredients are suitable for your dietary needs.
• Gluten-Free: This sausage and sauerkraut dish is inherently gluten-free, as both sauerkraut (fermented cabbage) and most kielbasa brands are naturally free of gluten. However, always double-check the labels on your bacon and sausage, as some processed meats may contain hidden gluten-containing additives.
• Adjusting Serving Size: The base recipe yields six servings. It’s simple to scale up or down to fit your needs. For larger batches, ensure your slow cooker has sufficient capacity; you may need to cook in batches if preparing a very large quantity.
• Make it Spicy: For those who enjoy a little heat, add a pinch or two of red pepper flakes to the slow cooker with the other ingredients. A dash of hot sauce before serving can also do the trick.

Frequently Asked Questions About Kielbasa and Sauerkraut

Here are answers to some common questions about this delightful dish and its components:

• Is sauerkraut Gluten-Free?
  Absolutely! Sauerkraut is naturally gluten-free, primarily consisting of fermented cabbage and salt. It’s a fantastic option for those following a gluten-free diet.
• Is Sauerkraut Keto-Friendly?
  Yes, sauerkraut is naturally low in carbohydrates, making it a great addition to a ketogenic diet.
• Does Sauerkraut Go Bad?
  While sauerkraut has a long shelf life due to fermentation, it can eventually go bad. Once opened, it should stay fresh in the refrigerator for at least a few months if stored properly in an airtight container.
• How Can You Tell if Sauerkraut Has Gone Bad?
  The first indicator is usually the smell. If your sauerkraut emits an unusually strong, off, or moldy odor, it’s best to discard it. Also, check for changes in color (beyond its typical pale yellow/green), a slimy or overly soft texture, or visible mold. When in doubt, throw it out.
• How Do You Sweeten Sauerkraut?
  If you find sauerkraut too tart, there are several ways to mellow its flavor:
  • Add a spoonful of white sugar or brown sugar during cooking.
  • Rinse and drain the sauerkraut thoroughly before adding it to the recipe.
  • Cook it with naturally sweet ingredients like sliced apples or caramelized onions.

Expert Tips for the Best Crockpot Kielbasa & Sauerkraut

Follow these simple tips to ensure your kielbasa and sauerkraut turns out perfectly every time:

• Sauté for Depth: Don’t skip browning the bacon and sautéing the onions (and even the kielbasa!). This step, often overlooked in slow cooker recipes, builds a foundational layer of flavor that makes a significant difference.
• Balance the Tang: The brown sugar is crucial for balancing the acidity of the sauerkraut. Adjust the amount to your personal preference – more for a sweeter dish, less for a tangier one.
• Drain Wisely: How much you drain the sauerkraut can affect the final dish’s tanginess and moisture content. If you prefer a less tart taste, rinse and drain it well. For a stronger flavor, simply drain the liquid without rinsing.
• Don’t Overcrowd: While slow cookers are forgiving, try not to fill yours more than two-thirds full. This ensures even cooking and optimal temperature regulation.
• Low and Slow is Key: For the most tender kielbasa and well-developed flavors, cooking on low for a longer duration is always recommended over high heat.
• Taste and Adjust: Always taste your dish before serving and adjust seasonings if needed. A pinch of salt, a dash of pepper, or a little more brown sugar can make a big difference.
