Medium yellow onion, finely chopped – 1
Kosher salt – 1 teaspoon, plus more to taste
Black pepper (optional, not counted toward 5 main ingredients) – ½ teaspoon, or to taste

Ingredient Notes

What kind of cabbage? Green cabbage is traditional. It has sturdy leaves that hold up well during slow cooking. Savoy cabbage is more tender and would cook faster. Red cabbage will work but will turn the soup purple.

What kind of diced tomatoes? Regular diced tomatoes work well. Fire-roasted diced tomatoes add a subtle smoky depth. Tomatoes with basil, garlic, or onion add extra flavor. Do not drain — the juices are essential for the broth.

What kind of broth? Low-sodium chicken broth adds savory depth. Vegetable broth keeps the soup vegetarian. Both work beautifully. If you only have regular broth, reduce the salt.

What kind of onion? Yellow onion is best. It has the right balance of sweetness and savory flavor. White onions are sharper; sweet onions (like Vidalia) will make the soup noticeably sweeter.

Do I need to add any other seasonings? The soup is intentionally simple. A pinch of garlic powder, dried thyme, or a bay leaf would be lovely additions, but they’re not necessary.

Do I need to grease the slow cooker? No. The liquid will prevent sticking.

What size slow cooker? A 5- to 6-quart slow cooker works best.

Step-by-Step Instructions

Step 1: Prepare the Cabbage

Remove any tough or wilted outer leaves from the 1 medium head of green cabbage. Cut the cabbage into quarters, remove the core, then chop the cabbage into bite-sized pieces. Set aside.

Step 2: Chop the Onion

Peel and finely chop the 1 medium yellow onion. Keeping the pieces small helps them soften and almost melt into the broth, which is nice for kids who don’t love big onion chunks.

Step 3: Layer in the Slow Cooker

Place the chopped cabbage into the bottom of a 5- to 6-quart slow cooker, spreading it out evenly. Scatter the chopped onion over the cabbage.

Step 4: Pour on the Tomatoes

Open the 2 cans of diced tomatoes and pour them, with all their juices, evenly over the chopped cabbage and onion in the slow cooker. This is the moment that really makes the recipe — just that simple pour over the fresh cabbage.

Step 5: Add Broth and Seasoning

Pour 4 cups of low-sodium chicken or vegetable broth around and over the tomatoes and cabbage. Sprinkle in 1 teaspoon of kosher salt and ½ teaspoon of black pepper (if using). Do not worry if the liquid doesn’t completely cover the cabbage; it will cook down as it simmers.

Step 6: Stir Gently

Use a large spoon to gently stir the mixture, pulling some of the tomatoes down into the cabbage so everything is lightly mixed. You don’t need to be fussy here — just combine enough so the flavors can mingle.

Step 7: Cover and Cook

Cover the slow cooker with the lid. Cook on:

LOW for 6 to 8 hours, or
HIGH for 3 to 4 hours

The soup is ready when the cabbage is very tender and the flavors have blended. The cabbage should be soft but not mushy, and the broth will be a rich tomato color.

Step 8: Taste and Adjust Seasoning

Once the soup is done, give it a good stir and taste the broth. Add a pinch more salt or pepper if needed. If it tastes a little flat, another small pinch of salt usually wakes it right up.

Step 9: Serve

Ladle the hot soup into bowls. If you’d like, finish with a crack of fresh black pepper on top. Serve with bread, crackers, or your favorite simple side and enjoy a comforting, no-fuss meal.

Storage & Reheating

Refrigerator: Store leftovers in an airtight container for up to 5 days. The flavors deepen overnight — this soup is often even better the next day.

Reheating:

Microwave: 1–2 minutes per serving.
Stovetop: Warm over medium-low heat, adding a splash of water or broth if needed.
Slow cooker: Warm on LOW for 30–45 minutes.

Freezing: This soup freezes beautifully for up to 3 months. Freeze in a freezer-safe container. Thaw overnight in the refrigerator before reheating. The cabbage may soften slightly, but the flavor remains excellent.

Frequently Asked Questions (FAQs)

Can I use chicken broth instead of vegetable broth?

Yes. Chicken broth adds savory depth. Vegetable broth keeps the soup vegetarian. Both work beautifully.

Can I use fresh tomatoes instead of canned?

Yes. Use about 2 cups of fresh diced tomatoes. You may need to add ½ cup of water or extra broth, as fresh tomatoes release less liquid.

Why is my cabbage still hard after cooking?

A few possibilities:

You cut the cabbage into very large pieces (cut into bite-sized pieces)
Your slow cooker runs cool (some older models do)
You didn’t cook it long enough (check at the longer end of the time range)

Why is my soup too watery?

The cabbage releases water as it cooks. If your soup is too watery, you can:

Cook with the lid off for the last hour to allow evaporation
Mash some of the cooked cabbage against the side of the slow cooker — it will release starch and thicken the broth

What should I serve with this soup?

Crusty bread – Essential for sopping up the broth
Crackers – Saltines or oyster crackers
Grilled cheese sandwich – For dipping
A simple green salad – With a tangy vinaigrette

Can I add meat to this soup?

Absolutely. Browned ground beef, Italian sausage, smoked ham hock, or shredded rotisserie chicken all work beautifully.

Can I double this recipe?

Use a 7- to 8-quart slow cooker for a double batch. Double all ingredients. Cooking time may increase by 30–60 minutes.

The Amish Tradition

In Amish and Pennsylvania Dutch communities, simple cabbage soup has been a staple for generations. Cabbage was a reliable crop that could be stored for months in a root cellar. It was cheap, filling, and nutritious.

This soup reflects that tradition — using simple, humble ingredients to create something warm and satisfying. The addition of tomatoes (canned) is a more modern convenience, but the spirit remains the same: honest food made with care.
