Jarred sauerkraut benefits from a quick rinse and a slow simmer with apples or caraway to balance its tangy bite. If you have ever wondered how to cook sauerkraut from a jar, you are in the right place. This guide will show you simple ways to turn that jar into a warm, comforting side dish or main ingredient.
Many people think sauerkraut is only for hot dogs or Reuben sandwiches. But cooking it from a jar opens up a world of flavor. You can make it milder, sweeter, or more savory with just a few additions. Let’s start with the basics.
Why Cook Sauerkraut From A Jar?
Jarred sauerkraut is already fermented and ready to eat. So why cook it? Cooking softens the texture and mellows the sharp acidity. It also lets you add flavors like apples, onions, or spices. The result is a dish that pairs well with pork, sausages, or even mashed potatoes.
You do not need to be a chef to do this. The process is straight forward and forgiving. Even if you make a mistake, it still tastes good.
How To Cook Sauerkraut From A Jar
This is the core section of our guide. Follow these steps to get perfect results every time. Remember, the key is to balance the sourness with sweetness or fat.
Step 1: Choose Your Jarred Sauerkraut
Not all jarred sauerkraut is the same. Look for brands that are refrigerated, not shelf-stable. Refrigerated kraut has live probiotics and better texture. Shelf-stable jars are pasteurized, which kills the good bacteria.
- Check the ingredients list. It should have cabbage, salt, and water only.
- Avoid brands with added vinegar or sugar. These are not traditional.
- Look for a “best by” date that is far in the future.
Step 2: Rinse Or Not To Rinse
This is a common debate. Rinsing removes some salt and acidity. It makes the kraut milder. If you like a strong tang, skip the rinse. For a more balanced flavor, rinse briefly in a colander.
Here is a simple rule: If the kraut tastes too salty or sour to you raw, rinse it. If you like it as is, do not rinse. You can also rinse half and mix it back together.
Step 3: Gather Your Ingredients
You need just a few things to cook sauerkraut from a jar. Here is a basic list:
- 1 jar (about 16 oz) sauerkraut, drained and rinsed if desired
- 1 small onion, sliced thin
- 1 apple, peeled and diced (optional but recommended)
- 1 tablespoon butter or oil
- 1 teaspoon caraway seeds (optional)
- 1/2 cup water, apple juice, or white wine
- Salt and pepper to taste
You can add other things like bacon, juniper berries, or a bay leaf. The apple and caraway are classic for a reason.
Step 4: Cook The Aromatics
Heat a medium saucepan over medium heat. Add the butter or oil. Once it melts, add the sliced onion. Cook for 3 to 4 minutes until soft and translucent. If you use bacon, cook it first until crispy, then remove it and cook the onion in the fat.
Add the diced apple now if using. Cook for another 2 minutes. The apple will soften and add sweetness.
Step 5: Add The Sauerkraut And Liquid
Add the drained sauerkraut to the pan. Stir it with the onions and apple. Pour in the water, apple juice, or wine. The liquid should come about halfway up the kraut. Do not drown it.
Add the caraway seeds, if using. Stir everything together. Bring the liquid to a gentle simmer, not a rolling boil.
Step 6: Simmer Low And Slow
This is the most important step. Cover the pan with a lid. Reduce the heat to low. Let it simmer for 20 to 30 minutes. Stir occasionally to prevent sticking.
The longer you simmer, the softer and milder the kraut becomes. Some people cook it for an hour or more. Taste it after 20 minutes and decide. You want it tender but not mushy.
Step 7: Adjust Seasoning
After simmering, taste the kraut. Add salt and pepper if needed. Remember that the kraut already has salt from the jar. Go easy. If it is too sour, add a pinch of sugar or a bit more apple juice.
If it is too dry, add a splash of water. If it is too wet, simmer uncovered for a few minutes to reduce the liquid.
Step 8: Serve And Store
Serve the cooked sauerkraut warm. It goes great with pork chops, sausages, or roasted chicken. You can also use it as a topping for hot dogs or in a Reuben sandwich.
Leftovers keep in the fridge for up to 5 days. The flavor actually gets better after a day. Reheat gently on the stove or in the microwave.
Variations To Try
Once you know how to cook sauerkraut from a jar, you can experiment. Here are some popular variations.
With Bacon And Beer
Cook 4 slices of bacon until crispy. Remove and crumble. Cook the onion in the bacon fat. Add the sauerkraut and 1/2 cup of beer (lager or pilsner works well). Simmer as usual. Stir in the bacon before serving.
Sweet And Sour Style
Add 2 tablespoons of brown sugar or honey along with the liquid. Use apple juice instead of water. This makes a sweeter kraut that kids often like. It pairs well with ham.
Spicy Version
Add 1/2 teaspoon of red pepper flakes or a chopped jalapeño with the onions. You can also add a dash of hot sauce at the end. This works great with grilled sausages.
German Style With Juniper
Add 3 to 4 juniper berries (crushed) and a bay leaf with the liquid. Use white wine instead of water. This gives a traditional German flavor. Remove the bay leaf before serving.
Common Mistakes To Avoid
Even simple recipes have pitfalls. Here are things to watch out for when you cook sauerkraut from a jar.
- Boiling instead of simmering: High heat makes the kraut tough and bitter. Keep it low.
- Skipping the rinse when needed: If the kraut is too salty, your dish will be inedible. Taste first.
- Adding too much liquid: You want the kraut moist, not swimming. Start with less and add more if needed.
- Not stirring: The bottom can burn if you leave it unattended. Stir every 5 to 10 minutes.
- Overcooking: While long simmering is fine, do not cook it for hours unless you want very soft kraut. Taste as you go.
Frequently Asked Questions
Can I Cook Sauerkraut From A Jar Without Rinsing It?
Yes, you can. Rinsing is optional. It depends on how salty or sour you want the final dish. If you like a strong flavor, skip the rinse. If you want it milder, rinse briefly.
How Long Should I Simmer Jarred Sauerkraut?
Simmer for 20 to 30 minutes for a balanced texture. You can go up to 1 hour for very soft kraut. Taste after 20 minutes to see if it is done to your liking.
What Is The Best Liquid To Use When Cooking Sauerkraut?
Water is fine, but apple juice or white wine adds sweetness and depth. Beer also works well. Avoid using broth that is too salty, as the kraut already has salt.
Can I Freeze Cooked Sauerkraut?
Yes, you can freeze it. Let it cool completely, then store in a freezer-safe container. It keeps for up to 3 months. Thaw in the fridge overnight and reheat gently.
Is Cooked Sauerkraut Still Healthy?
Yes, but cooking kills the probiotics (good bacteria) from fermentation. You still get fiber, vitamins C and K, and antioxidants. For probiotics, eat some raw sauerkraut before cooking the rest.
Tips For Best Results
Here are a few extra pointers to make your sauerkraut even better.
- Use a non-reactive pan like stainless steel or enameled cast iron. Avoid aluminum or copper, which can react with the acid.
- Add a small potato to the pot while simmering. The potato absorbs excess salt and sourness. Discard it before serving.
- Let the cooked kraut rest for 10 minutes before serving. This allows the flavors to meld.
- Double the recipe and freeze half. Cooked sauerkraut freezes well and makes a quick side dish later.
- Pair with fatty meats like pork shoulder or duck. The fat balances the acidity.
