Kapustnyak Sauerkraut Soup with Potatoes and Bacon

Kapustnyak is a sauerkraut soup with many household variations. This version uses bacon, potatoes and a simple vegetable base, with no grain added. Cooking potatoes before the sour cabbage matters because acidity can slow their softening. Drain and taste the sauerkraut before deciding whether to rinse it; removing all its character would make the soup bland. Dill goes in at the end to bring a fresh note to the smoky, tangy broth.

Ingredients and directions

Doneness checks

Potatoes are tender before sauerkraut enters; cabbage strands soften in hot broth.

Helpful tips

• Cook potatoes before adding acidic sauerkraut.
• Taste cabbage before rinsing it.
• Use low-sodium stock to control saltiness.
• Add dill after the long simmer.

Troubleshooting

• Acidic sauerkraut may have entered too early. Simmer potatoes in plain broth until tender first.
• Cook potatoes before adding acidic sauerkraut.

Serving ideas

• Serve with rye bread.
• Offer sour cream separately if desired.
• Use a deep bowl for the brothy soup.
• Add a crisp cucumber side plate.

Substitutions

Cooked smoked turkey can replace bacon, with 1 tablespoon oil for the vegetable base. Vegetable stock changes the broth but does not make a bacon-containing soup vegetarian.

Variation

Add 1/4 teaspoon caraway seeds with the vegetables for a different aromatic note.

Make ahead

Cook the full soup a day ahead and chill promptly. Add fresh dill after reheating rather than boiling it repeatedly.

Storage and reheating

Cool promptly in shallow containers and refrigerate for up to 3–4 days. Reheat to 74°C (165°F), bringing the broth to a boil. Freeze for up to 2 months; potatoes may soften.

Food safety

Use clean utensils and wash produce. Keep perishable ingredients refrigerated at 4°C (40°F) or below. Refrigerate perishable leftovers promptly, within 2 hours, or within 1 hour above 32°C (90°F).
