Back in the archives of the blog there’s a popular recipe called Stuffed Pepper Soup. If you’re not watching your carbs, that’s a delicious soup recipe made from all the ingredients you might use in stuffed peppers like green bell pepper, onion, sausage, ground beef, tomatoes, and herbs. There are a few added ingredients to add flavor, and there is also rice. The soup doesn’t have a huge amount of rice in each serving and I use low-glycemic Uncle Ben’s Converted Rice (affiliate link), but it’s still too much rice for it to be considered a low-carb recipe.

I did say in the notes after the Stuffed Pepper Soup Recipe that I thought it would work well with cauliflower rice, so I’m not so sure why it took me so long to try it. But I can happily report that this Low-Carb Stuffed Pepper Soup (with cauliflower rice) is absolutely the bomb! I’ve already eaten some of my leftovers and I have more in the freezer waiting for a cold night.

We used frozen cauliflower rice which also made it easy, and the frozen cauliflower pieces were nice and small and cooked quickly, but you could definitely use chopped cauliflower and just cook it a bit longer. In the low-carb version we used a bit more sausage and left out the mushrooms, but you could add some chopped mushrooms if you’d like. And if you like all those stuffed pepper flavors I described above, I hope you’ll try this soup!

How to Make Low-Carb Stuffed Pepper Soup:

(Scroll down for complete recipe with nutritional information.)

  1. Heat 2 teaspoons olive oil in a non-stick pan, saute the onion until it’s just starting to brown, then add the Italian Herb Seasoning (affiliate link) and cook a few minutes more. Add the onion to the soup pot.
  2. Add the chopped green peppers and cook until they are starting to slightly char. Add the peppers to the soup pot.

  4. Then add the crushed tomatoes, water, beef broth, Worcestershire sauce, and low-sugar ketchup, bring the soup to a low simmer and let it cook 30-40 minutes.
  5. Then add 2 cups of frozen cauliflower rice (or cauliflower you’ve chopped in the food processor) and cook 20-30 minutes longer. Use the longer cooking time for fresh cauliflower.

Enjoy stuffed pepper flavors without the carbs with this delicious Low-Carb Stuffed Pepper Soup.


  • 4 tsp. olive oil
  • 1 onion, chopped small
  • 1 T Italian Herb Blend
  • 2 large green bell peppers, seeds and stems removed and chopped into half-inch pieces
  • 19.5 oz. uncooked turkey Italian sausage, squeezed out of the casing ()
  • 1 lb. ground beef
  • 2 15 oz. cans crushed tomatoes + 2 cans water (rinse out the can with the water)
  • 4 14 oz. cans beef broth (or use 7 cups homemade beef stock)
  • 1 T Worcestershire Sauce (or more)
  • 1/2 cup ketchup (I used Heinz Reduced-Sugar Ketchup)
  • 2 cups frozen cauliflower rice (Available at Trader Joes, Target, Kroger, and many other stores.)
  • salt and fresh-ground pepper to taste
  • freshly-grated Parmesan for serving (optional)


  1. Heat 2 tsp. of olive oil in a large non-stick frying pan. (I used my favorite Green Pan (affiliate link) the largest  size frying pan.)
  2. Add the chopped onion and cook until the onion is just starting to brown; then add the Italian Herb Seasoning (affiliate link) and cook a few minutes more. Put the seasoned onions into a large soup pot.
  1. Add the chopped green peppers to the same frying pan and cook until they start to slightly char. Add peppers to the soup pot.
  2. Add the other 2 tsp. of oil to the frying pan, add the sausage that you squeezed out of the links and the ground beef, and cook over medium-high heat until the sausage and beef is slightly browned. You might have to cook the beef and sausage separately if you don’t have a big enough frying pan. Use your turner to break the ground beef and sausage apart as it cooks. (Or I sometimes use an old-fashioned potato masher (affiliate link) to break the meat apart.)
  3. Add the beef and sausage to the soup pot.
  4. Add the crushed tomatoes, water, beef broth, Worcestershire sauce, and low-sugar ketchup, bring the soup to a low simmer and let it cook 30-40 minutes.
  5. Then add the 2 cups of frozen (or fresh chopped) cauliflower rice and let the soup cook 20-30 minutes more, or slightly longer for fresh cauliflower. Season to taste with salt and fresh-ground black pepper.
  6. Serve hot, with fresh Parmesan to add at the table if desired.


I used 5 links of hot Italian sausage, but if making for kids I might choose milder sweet Italian sausage.

This soup will keep quite a few days in the fridge and also freezes well. For best results, reheat in a small pan on the stove.
