How to Make Sauerkraut Soup (Kapustnyak) Recipe
Step 1: Cook the bacon until golden
Begin by heating the olive oil in a large soup pot or Dutch oven. Toss in the chopped bacon and sauté it until it’s beautifully browned and crisp. Once done, scoop it out carefully with a slotted spoon and set it aside. This crispy bacon is going to add both texture and that crave-worthy smoky flavor throughout the soup.
Step 2: Sauté the celery and onion
In the same pot, using the bacon fat and olive oil, add the finely diced celery and onion. Let them cook gently over medium heat until they turn softened and golden, about five minutes. This step unlocks the natural sweetness and builds a fragrant foundation for the soup’s layers of flavor.
Step 3: Add the veggies, quinoa, and broth
Next, stir in the thinly sliced carrots, potatoes, and the optional rinsed quinoa. Pour in the eight cups of low sodium chicken broth and two cups of water. Bring everything up to a boil, then lower the heat to a gentle simmer. Let it cook for 15 minutes so the potatoes and carrots begin to soften while the quinoa plumps up, adding a lovely texture contrast.
Step 4: Incorporate sauerkraut, beans, and bacon
Now, add the well-rinsed and drained sauerkraut along with half of the reserved cooked bacon. Pour in the canned white beans with their juice for extra creaminess and protein, and toss in a bay leaf to infuse delicate herbal aromas. Continue simmering until the potatoes are perfectly tender, about 10 more minutes. Season carefully with salt, pepper, and Mrs. Dash seasoning to taste, making sure every spoonful sings with balanced flavor.

Side Dishes
This soup pairs irresistibly well with fresh crusty bread or a hearty rye loaf to soak up every last drop of broth. A side salad with fresh cucumbers or radishes brings a crispness that contrasts nicely. For a more filling meal, serve alongside boiled or baked potatoes or a light cheese platter.

Make Ahead and Storage
Storing Leftovers
Once cooled, transfer your leftover sauerkraut soup into airtight containers and store it in the refrigerator. It will keep beautifully for 3 to 4 days, allowing you to enjoy the warm, hearty flavors long after cooking day.
Freezing
This soup freezes exceptionally well, making it a fantastic meal prep option. Freeze in freezer-safe containers or bags, leaving room for expansion. When frozen, it will keep its flavor and texture for up to 3 months, ready whenever you crave a comforting bowl of Kapustnyak.
Reheating
Reheat the soup gently over medium heat on the stove, stirring occasionally until warmed through. Avoid boiling vigorously to preserve the delicate flavors and texture of the ingredients. If the soup thickens too much after refrigeration or freezing, simply add a splash of water or broth while reheating to restore the perfect consistency.
FAQs
What can I use instead of bacon for a vegetarian version?
You can substitute smoked paprika and a splash of liquid smoke to recreate some of that smoky flavor. Adding sautéed mushrooms or smoked tofu cubes also brings lovely depth without meat.
Do I have to rinse the sauerkraut before adding it?
Yes, triple rinsing and draining your sauerkraut helps balance the acidity and prevents the soup from becoming overly sour. It ensures the tanginess is just right and complements the other ingredients beautifully.
Can I cook this soup in a slow cooker?
Absolutely! Brown the bacon and vegetables first, then add all ingredients to the slow cooker except for the sauerkraut and beans. Add those halfway through the cooking process. Cook on low for 6-8 hours or high for 3-4 hours for tender vegetables and deep flavors.
Is quinoa necessary in this recipe?
Quinoa is optional but recommended if you’re looking to boost protein and texture. If you don’t have it on hand, you can simply omit it, and the soup will still be hearty and delicious.
How spicy is Sauerkraut Soup (Kapustnyak) Recipe?
This recipe is naturally mild and tangy with smoky undertones but not spicy. You can bump up the heat by adding a pinch of cayenne pepper or some crushed red chili flakes if you like a spicy kick.
