How to Make Crockpot Polish Sausage, Sauerkraut, and Potatoes
Step 1: Prepare the Ingredients
Wash the potatoes thoroughly and cut them into evenly sized chunks, approximately 1 to 1½ inches wide. You can peel them if you prefer, but leaving the skins on saves time and adds texture.
Slice the Polish sausage into thick rounds. Cut the onion into thin slices so it softens easily as it cooks.
Prepare the sauerkraut according to your taste. If you prefer a milder flavor, drain it and give it a quick rinse. If you enjoy a stronger, tangier taste, keep some of its liquid. The juice adds acidity and helps flavor the potatoes.
Step 2: Add the Potatoes and Onion
Place the potatoes in the bottom of your slow cooker, followed by the sliced onion.
The potatoes benefit from being placed near the bottom because this area tends to receive more direct heat. Spread them out as evenly as possible so they cook consistently.
Sprinkle the garlic powder, black pepper, and paprika over the potatoes. If you're using mustard, stir it into the broth before adding the liquid.
Step 3: Add the Sauerkraut and Sausage
Spread the sauerkraut over the potatoes and onion. Arrange the sliced Polish sausage on top.
You can gently toss the ingredients together if you want the flavors distributed more evenly. Alternatively, keep the sausage near the top for a more attractive presentation when serving.
Add the chicken broth or water around the sides of the slow cooker. You don't need to cover all the ingredients with liquid. Sauerkraut releases moisture as it cooks, and too much liquid can make the potatoes watery.
If you enjoy a slightly richer finish, scatter a few small pieces of butter over the top.
Step 4: Let the Slow Cooker Do the Work
Cover the slow cooker with its lid and cook until the potatoes are fork-tender.
LOW: Approximately 6–8 hours.
HIGH: Approximately 3–4 hours.
Cooking times vary depending on the size of your potato pieces, your slow cooker, and how full the crock is. Check the potatoes near the end of the cooking time rather than relying on the clock alone.
Avoid lifting the lid repeatedly, as this allows heat to escape and can lengthen the cooking time.
Step 5: Stir Gently and Serve
Once the potatoes are tender, gently stir the mixture to distribute the sausage juices and sauerkraut throughout the dish.
Taste and adjust the seasoning if needed. Sauerkraut and sausage can both be salty, so it's best to taste before adding extra salt.
Serve the meal hot, with a little fresh parsley if you like. A spoonful of Dijon mustard on the side is also delicious for anyone who enjoys a sharper, more savory flavor.
Tips for the Best Results
Cut the potatoes evenly. Similar-sized pieces cook at roughly the same rate. Very large chunks may remain firm while smaller pieces become too soft.
Don't add too much liquid. This is meant to be a moist, hearty dish rather than a soup. Start with a modest amount of broth and let the sauerkraut provide additional moisture.
Choose the right sausage. Smoked kielbasa gives the recipe a deep, savory flavor. If you're using fresh, uncooked sausage instead of a fully cooked smoked variety, handle and cook it according to food-safety guidance, ensuring it reaches the appropriate safe internal temperature.
Adjust the sauerkraut to your taste. Draining or rinsing it creates a milder dish. Keeping some of the brine gives the finished meal a stronger tang.
Wait before adding extra salt. Sausage and sauerkraut can contain substantial amounts of sodium. Taste the finished dish first, then season as necessary.
Keep the lid closed. Every time you remove the lid, heat escapes. Check the potatoes near the end rather than stirring the mixture throughout the day.
Easy Variations to Try
Add Carrots
For extra color and a little natural sweetness, add two sliced carrots with the potatoes and onion. They soften during cooking and balance the tanginess of the sauerkraut.
Use Different Potatoes
Baby potatoes, red potatoes, and Yukon Gold potatoes all work well. If you use russet potatoes, cut them into slightly larger pieces to help them maintain their texture.
Make It More Savory
Add a teaspoon of caraway seeds for a traditional flavor often associated with sauerkraut dishes. A little extra black pepper or a teaspoon of Dijon mustard can also deepen the overall taste.
Add Apples
For a slightly sweeter, traditional-style variation, add one firm apple cut into wedges. Apples pair nicely with cabbage, sausage, and potatoes, creating a gentle sweetness that contrasts with the sauerkraut.
Give It a Smoky Twist
If you love smoky flavors, use a smoked kielbasa and add a small pinch of smoked paprika. Be careful not to overdo it, since the sausage already contributes plenty of smoky flavor.
Make It Spicy
Add a pinch of crushed red pepper flakes or a little sliced jalapeño. The heat works especially well with the sour sauerkraut and rich sausage.
What to Serve With Polish Sausage, Sauerkraut, and Potatoes
This crockpot meal is filling enough to serve on its own, but a simple side dish can make dinner feel more complete.
Crusty bread: Perfect for soaking up the savory juices.
Green salad: Fresh greens with a light vinaigrette offer a refreshing contrast.
Steamed green beans: A simple vegetable side adds color without overpowering the main dish.
Roasted carrots: Their natural sweetness pairs well with the sauerkraut.
Mustard: Dijon or whole-grain mustard adds a sharp, tangy finish.
Rye bread: A particularly fitting choice for a Polish-inspired meal.
For a cozy family dinner, serve generous portions in shallow bowls with warm bread on the side.
How to Store Leftovers
Allow leftovers to cool slightly, then transfer them to shallow, airtight containers. Refrigerate within two hours of cooking.
Stored properly in the refrigerator, leftovers are generally best eaten within 3–4 days. Reheat only the portion you plan to eat, using a microwave or stovetop until the food reaches 165°F (74°C).
If the mixture seems dry after refrigeration, add a tablespoon or two of water or broth before reheating.
You can also freeze leftovers in airtight, freezer-safe containers for approximately 2–3 months for best quality. Keep in mind that the potatoes may become softer or slightly grainy after thawing. Thaw in the refrigerator before reheating thoroughly.
Frequently Asked Questions
Do I need to brown the Polish sausage first?
No. If you're using fully cooked smoked Polish sausage or kielbasa, you can add it directly to the slow cooker. Browning it in a skillet first is optional, but it can create a deeper, roasted flavor.
Should I rinse the sauerkraut before adding it?
That depends on your preference. Rinsing makes the dish milder and less sour. If you love the traditional tangy taste of sauerkraut, simply drain some of the liquid or add it directly according to how strong you want the flavor to be.
Can I prepare this recipe the night before?
Yes. You can slice the sausage, chop the onion, and measure the seasonings in advance. For best quality and food safety, refrigerate the prepared ingredients in covered containers rather than leaving raw cut potatoes and other ingredients at room temperature overnight. Assemble the dish when you're ready to cook.
Can I cook this recipe without chicken broth?
Absolutely. Water works perfectly well because the sausage and sauerkraut contribute plenty of flavor. You can also use vegetable broth or a low-sodium stock.
Why are my potatoes still hard?
The pieces may be too large, the slow cooker may not have reached a sufficient cooking temperature, or the lid may have been lifted frequently. Continue cooking until the potatoes are fork-tender. Cutting them into evenly sized pieces next time can help.
Can I use fresh sausage instead of smoked kielbasa?
Yes, but the cooking and food-safety requirements may differ. Fresh sausage is not the same as fully cooked kielbasa, so make sure it reaches the safe internal temperature appropriate for its meat type. For pork or beef sausage, the standard minimum is 160°F (71°C); poultry sausage should reach 165°F (74°C). Avoid relying on cooking time alone to determine whether fresh sausage is done.
Is this recipe very salty?
It can be, depending on the sausage, sauerkraut, and broth you use. Choose low-sodium broth, drain or rinse the sauerkraut if desired, and avoid adding salt until you've tasted the finished dish.
