the ingredients

Keto cabbage soup is loaded with low-carb vegetables, aromatics like garlic and onions, and slices of smoked sausage.

But you want to know what makes this cabbage soup recipe extra special and delicious? Roasted vegetables.

Here are the simple ingredients you will need for this hearty keto cabbage soup:

• Olive oil or avocado oil. For cooking the veggies. Either type works!
• Vegetables. I use a mix of chopped celery, carrots, onion, and green cabbage. They will roast in the oven first, which gives them a lovely, caramelized flavor and makes an extra delicious cabbage soup.
• Garlic. For the perfect savory notes that take this soup to the next level. 
• Chicken or vegetable broth. You can also use chicken stock or homemade chicken bone broth!
• Spices and seasonings. Red pepper flakes, Italian seasoning, salt and black pepper are all you need.
• Sausage. Choose a high-quality, heavily spiced sausage variety like Kielbasa, Italian sausage, or Andouille. Keep in mind that the sausage can effect the spice level of the soup. The spicier the sausage, the spicier the soup will be!

tips for the best results

• Don't skip roasting the vegetables: Roasting the vegetables before adding them to the soup gives this keto cabbage soup extra flavor that makes it super yummy. Yes, it's an extra step but is so worth it! The roasting time caramelizes the vegetables which gives them even more flavor and a sweeter note once they're in the broth.

• Browning the sausage: I cook the slices over a high heat, just to brown them slightly. They will heat all the way through when the soup simmers.

• Season to taste: Taste the soup at the very end and add salt, pepper, and more red pepper flakes or Italian seasoning as needed.

• Substitutions: Feel free to use vegetable or chicken broth, bone broth or stock. For a vegetarian option, you can omit the sausage, double up on the roasted veggies, and use vegetable broth instead of chicken broth. 

• Choosing sausage: This cabbage and smoked sausage soup is really good with any variety of high-quality sausage links (not ground sausage) that have good flavor on their own. This can be a Whole30 and paleo cabbage soup recipe too- just be mindful of the ingredients in the sausage you choose. I usually go for brands that are marketed as paleo, Whole30 or keto-friendly.

• Storage: Transfer leftovers to an airtight container and store in the refrigerator for up to five days. Reheat in the microwave or on the stove top. 

cabbage sausage soup variations

This cabbage soup recipe is an easy one to adapt and make your own! Here are a few ideas for tasty variations:

• Leeks or shallots. Either of these can be added to the soup or swapped in for onion. Clean and slice the leeks and roast with the rest of the vegetables. If using shallots, mince them and add them to the pot at the same time as the garlic.

• Sweet potato. If you're not opposed to sweet potato, one sweet potato (cut into cubes) would be delicious in this and won't add too much to the carb count. Roast it with the rest of the veggies before adding it to the soup.

• Extra spicy. For even more spice, add sriracha to the soup (to taste) or spicy seasonings like a dash of cayenne pepper or chipotle powder.

• Cheese. A sprinkle of Parmesan cheese, grated mozzarella, or gruyere makes a yummy topping when serving the soup.
