Step-by-Step Instructions

Step 1 — Prepare the Sausages

Slice the smoked sausages into ½-inch rounds. For a deeper flavor, you can quickly brown them in a skillet over medium-high heat for 2-3 minutes before adding them to the slow cooker. This step is optional but adds a nice caramelized note to your Slow Cooker German Potato Soup with Sausages.

Step 2 — Chop the Vegetables

Dice one large onion, two carrots, and three celery stalks. Peel and cube 2 pounds of Yukon Gold or russet potatoes into 1-inch pieces. Consistent sizing ensures all the vegetables cook evenly in the soup.

Step 3 — Combine Ingredients in the Slow Cooker

Add the sliced sausages, chopped vegetables, and cubed potatoes to your slow cooker insert. Pour in 6 cups of low-sodium chicken or vegetable broth. Stir in 1 teaspoon of caraway seeds, a bay leaf, and season with salt and black pepper to taste.

Step 4 — Set the Cook Time

Cover and cook on the LOW setting for 7-8 hours or on the HIGH setting for 4-5 hours. The soup is done when the potatoes are fork-tender and easily break apart. Avoid overcooking, as the potatoes can become mushy.

Step 5 — Create the Roux (Optional Thickener)

For a thicker, creamier soup, about 30 minutes before serving, melt 3 tablespoons of butter in a saucepan. Whisk in 3 tablespoons of all-purpose flour and cook for 1-2 minutes to form a roux. Slowly ladle in 1-2 cups of the hot soup broth, whisking constantly to avoid lumps.

Step 6 — Incorporate the Roux and Final Seasoning

Pour the smooth roux mixture back into the slow cooker and stir well to combine. Let the soup cook for another 20-30 minutes on HIGH to allow it to thicken. Taste and adjust seasoning with more salt and pepper if needed.

Step 7 — Serve and Garnish

Ladle the hot Slow Cooker German Potato Soup with Sausages into bowls. For authentic German flair, garnish with freshly chopped parsley or chives. A dollop of sour cream or a sprinkle of crispy bacon bits also makes a delicious topping.

Common Mistakes to Avoid

• Mistake: Overfilling the slow cooker. Fix: Keep it ⅔ full max to ensure even cooking and prevent overflow.
• Mistake: Adding dairy too early. Fix: Stir in cream or milk in the last 30 minutes to avoid curdling.
• Mistake: Using the wrong potato type. Fix: Opt for waxy potatoes like Yukon Golds; they hold their shape better.
• Mistake: Not browning the sausages first. Fix: Searing unlocks deeper flavor that slow cooking alone can’t achieve.
• Mistake: Skipping the broth taste test. Fix: Season gradually; slow cooking concentrates saltiness over time.
• Mistake: Cutting vegetables unevenly. Fix: Uniform dices ensure everything cooks at the same rate.
• Mistake: Lifting the lid frequently. Fix: Resist peeking; each opening adds 15-20 minutes to cook time.
• Mistake: Forgetting to deglaze the pan. Fix: Scrape browned bits from searing into the slow cooker for extra flavor.

Storing Tips

• Fridge: Cool your Slow Cooker German Potato Soup with Sausages completely before transferring to an airtight container. It will keep for 3-4 days.
• Freezer: Freeze in a freezer-safe container or heavy-duty bag for up to 3 months. Leave some space for expansion.
• Reheat: Thaw frozen soup overnight in the refrigerator. Reheat on the stovetop or in the microwave, stirring occasionally, until it reaches an internal temperature of 165°F (74°C) for food safety.

For best texture, the potatoes may soften slightly after freezing and reheating, but the hearty flavors of this German potato soup will remain delicious.
