Looking for a guilt-free, flavorful, and low-carb meal that’s simple to prepare? This low-carb cabbage soup combines nutritious cabbage, cauliflower, and other wholesome vegetables to deliver a satisfying, Keto-friendly dish. Below is an easy Instant Pot version, with tips for stovetop and slow cooker methods.

The Best Low Carb Items To Buy In Bulk
Buying low-carb staples in bulk makes meal prep faster and more affordable. I regularly stock cauliflower (fresh and frozen cauliflower rice), celery, and cabbage. These versatile vegetables appear in many of my favorite recipes, such as egg roll in a bowl, a keto cabbage and beef casserole, and this Instant Pot cabbage soup. They keep well and can be used in salads, casseroles, soups, and quick skillet meals.

Perfect Soup For Meal Prep
This soup is low in carbs and calories, reheats beautifully, and holds up well in the fridge, making it an ideal meal-prep choice. Enjoy it for lunch or pair it with a simple low-carb side such as cloud bread for dinner. Cooking it in the Instant Pot keeps cleanup minimal, and it’s easy to double the batch for leftovers.

The recipe is provided in the printable card below. Before you start, here are a few helpful tips to get the best results.
How To Make The Soup Spicier
This cabbage soup is mild, which kids and sensitive palates usually prefer. If you want more heat, stir in 1/2 teaspoon cayenne pepper or a pinch of red pepper flakes when you add the seasonings. A spicier version can also be soothing if you’re feeling under the weather.

How To Make Cabbage Soup On Stove And Slow Cooker
If you don’t have an Instant Pot, this soup is just as easy in a slow cooker or on the stove. Prep is the same: chop the vegetables and combine the ingredients in one pot.
Slow cooker: Add all ingredients to the slow cooker and cook on low for about 8 hours or on high for about 4 hours.
Stovetop: Combine everything in a large soup pot and simmer on low for about an hour, stirring occasionally, until the vegetables are tender.
Serve with crunchy keto crackers or a low-carb side for a complete meal.

Low-Carb Instant Pot Soup Tips

Saute Meat In the Instant Pot
Start by setting the Instant Pot to the sauté function and browning the ground meat. This step takes just a few minutes and builds flavor. Add the garlic near the end of the sauté so it releases its aroma but doesn’t burn.

Cook until the meat is browned and fragrant, then add the remaining ingredients.

Add Soup Ingredients
After the meat is browned, turn off the sauté setting and add chopped cabbage, canned tomatoes with their juices, water, paprika, and any additional seasonings. Using the empty tomato can to measure and add water is an easy trick for the right liquid ratio.

Set Instant Pot At Soup Setting
Choose the soup setting and set it for 20 minutes. When cooking finishes, allow a natural pressure release. After opening the lid, stir in the cauliflower rice and replace the lid for 5 minutes to let the cauliflower warm through and absorb some broth. This keeps the texture pleasant without turning it mushy.
