This easy homemade sauerkraut recipe is one of the simplest and most rewarding ferments you can make. With just cabbage, salt and time, you can create tangy, probiotic-rich homemade sauerkraut that supports gut health and adds brightness to almost any dish. This guide walks you through the traditional fermentation method, explains the science behind it, and includes a troubleshooting section so you can confidently handle common issues like yeast, mold, and brine problems.
What is sauerkraut? Sauerkraut literally means “sour cabbage” in German. It is made by fermenting finely shredded cabbage with salt, allowing natural lactic acid bacteria to convert the sugars into lactic acid. This fermentation process naturally preserves the cabbage and creates its distinctive sour flavor.
Sauerkraut is one of those rare foods that is both incredibly simple and surprisingly powerful. At its core, it’s just cabbage and salt, but through natural fermentation it transforms into a probiotic-rich staple that supports digestion, improves gut health, and adds brightness to almost any meal.
Cultures around the world have depended on fermented cabbage for centuries, not only for its flavor, but also for its ability to preserve nutrients and keep vegetables fresh long after harvest.
Why make sauerkraut at home? Making sauerkraut at home is more than a cooking project, it gives you complete control over quality, flavor and nutrition.
Most store-bought versions are convenient, but many are pasteurized or preserved with vinegar, meaning they don’t contain the live probiotics that make traditional sauerkraut so beneficial. When you ferment it yourself, you get the full spectrum of live bacteria, a clearer ingredient list, and the freedom to customize flavors by adding ingredients like garlic, jalapeños, caraway, ginger, or whatever inspires you.
It’s also incredibly cost-effective. A single head of cabbage can yield a jar of sauerkraut that lasts for months, and the process requires no special equipment. All you need is a jar, some sea salt and a little patience.
Homemade sauerkraut is not only fresher and more vibrant than most store-bought versions, but also deeply satisfying to create. Once you learn how easy it is to make, you’ll want to keep it as a staple in your home.
Sauerkraut recipe: ingredients and equipment
You only need a few simple ingredients and basic tools to make this traditional sauerkraut recipe at home:
Ingredients 1 medium green cabbage (about 2 to 3 pounds) 1.5 to 2 tablespoons of fine sea salt (2 to 3% of the weight of the cabbage) Optional: caraway seeds, garlic, juniper berries or other flavorings Equipment Large mixing bowl Cutting board and sharp knife 1 liter mason jar or fermentation jar Fermentation weight (a smaller jar, glass weight, or bag filled with water) Clean cloth or airlock cover How to Make Sauerkraut: Step-by-Step Instructions Step 1: prepare the cabbage Remove any damaged outer leaves. Quarter the cabbage, remove the core and cut into thin strips. The thinner the slices, the faster and more uniform the fermentation. A food processor with a shredding attachment makes this step quick and easy.
Step 2: Salt and massage Place the shredded cabbage in a large bowl and sprinkle with salt. Massage for 5 to 10 minutes until:
The cabbage softens It releases enough liquid to form a brine Volume decreases significantly This brine is essential: it protects the cabbage from oxygen and harmful microbes.
Step 3: Pack the Jar Transfer the cabbage to your jar or do a handful at a time, pressing firmly to remove air pockets. Pour any remaining brine from the bowl over the top. Add filtered water if necessary to completely cover the cabbage.
Step 4: Submerge the Cabbage Place a fermentation weight on top to keep the cabbage completely submerged. This prevents mold and ensures a safe anaerobic environment.
Step 5: Cover and Ferment Cover the pot either with a cloth secured with an elastic band or with a fermentation lid with an airlock. Place your pot in a cool, dark place (65 to 72°F is ideal).
Step 6: Fermentation for 1 to 4 weeks Check daily for the first few days:
Press the weight if the cabbage exceeds the brine Skim off any harmless surface bubbles Taste after 7 days. When it reaches your favorite tangy taste, place it in the refrigerator to slow fermentation.
How to know when sauerkraut is ready Perfectly fermented sauerkraut with the ideal texture Your sauerkraut is cooked when:
It smells pleasantly salty and sour It has a tangy and crispy taste The brine is cloudy (a normal sign of active fermentation) Longer fermentation creates a deeper flavor. A shorter fermentation results in a milder kraut. The choice is yours!
Sauerkraut Salt Ratio: How Much Salt to Use The correct salt ratio is crucial for successful fermentation. Use 2 to 3% salt per weight of your cabbage.
No scales required: simple salt measurement Use 1½ to 2 teaspoons of fine sea salt per pound of shredded cabbage:
1½ teaspoons per pound ≈ 2% salt: milder flavor, faster fermentation 2 teaspoons per pound ≈ 2.5% salt: firmer, crisper, more resistant to mold Important: Always use non-iodized sea salt or kosher salt. Iodized table salt can inhibit fermentation.
Sauerkraut Troubleshooting: Common Problems and Solutions Fermentation is simple, but small problems can arise. Here’s how to handle them with confidence.
1. White/gray film on top (Kahm yeast) What is this : Harmless yeast due to exposure to oxygen.
What to do: Scrape, clean the edge of the pot and keep the cabbage submerged. Safe if smell/taste is normal.
2. Mold (black, pink, red, fuzzy or widespread growth) What is this : Harmful mold that can produce mycotoxins.
What to do: Discard the lot. Don’t recover.
Prevention: Keep cabbage submerged, 2-3% salt, sanitize jars/utensils.
3. Not enough brine Causes: Cabbage too dry, not massaged, not very salty.
Fix: Add 2% salt water (½ teaspoon per cup) until the cabbage is submerged.
4. Sauerkraut is too salty Causes: Excess salt.
Fix: Rinse lightly, replace ½ cup brine with water, use less than 2-3% salt next time.

5. Sauerkraut is mushy Causes: Low salt, hot fermentation, poorly packaged cabbage.
Fix: Use firm cabbage, in a cooler place, respect 2 to 3% salt.
6. Sauerkraut smells rotten or “off” Signs of deterioration: Rotten/sulfur smell, slimy, brown/discolored cabbage.
Fix: Discard the batch, start from scratch with clean equipment and appropriate salt.
6 Tips for Perfect Sauerkraut Every Time Follow these tips to ensure sauerkraut success:
Use fresh, dense cabbage, it will hold more water and produce more brine Keep everything clean but not sterile (fermentation needs natural bacteria) Maintain a cool, stable temperature (65 to 72°F) Always keep the cabbage completely submerged under the brine Taste regularly. Fermentation is smooth and forgiving Start with small batches until you are comfortable with the process How to store homemade sauerkraut Once your sauerkraut reaches the desired level of spiciness, transfer it to the refrigerator. The cold temperature slows fermentation considerably, allowing your sauerkraut to retain its flavor and texture for several months.
Always use clean utensils when serving to avoid contamination. Properly stored sauerkraut can last 4 to 6 months in the refrigerator, although it is often eaten much sooner!

Tips and troubleshooting
A cloudy brine is normal and indicates active fermentation. Kahm yeast (white/gray film) is harmless. Scrape it off, clean the rim of the pot and make sure the cabbage stays submerged.
Mold (black, pink, red or fuzzy) is dangerous. Throw the whole lot away. Not enough brine? : Add a small amount of 2% salt water brine (½ teaspoon of salt per cup of water). Too salty? : Rinse lightly before eating or use less salt next time.
Pasty texture: caused by low salt levels or hot temperatures. Keep the ferment cool and use 2 to 3% salt. The Simple Salt to Cabbage Ratio: No Rules Required for the Scale
Use 1½ to 2 teaspoons of fine sea salt per pound of shredded cabbage.
This corresponds to the safe fermentation range:
• 1½ teaspoons per pound ≈ 2% salt
• 2 teaspoons per pound ≈ 2.5% salt
Both are correct (choose based on taste and texture):
• 2% (1½ teaspoon/pound): gentler and faster fermentation
• 2.5% (2 tsp/lb): firmer, crunchier, more resistant to mold
