Ingredients assembled to make Keto Hamburger Soup, and all the ingredients in a pot

Ingredients and Variations

MEAT – Ground beef is super tasty in soup! No hamburger? Use leftover meat like chicken or turkey, which are both equally low carb. Toss in some bacon bits for some extra flavor!

VEGGIES  – This recipe has a colorful assortment of vegetables but cauliflower and cauliflower rice really make it hearty and filling. However, broccoli, spinach, zucchini, bell peppers, even mushrooms make a great addition to hamburger soup.

BROTH – A combination of beef broth and diced tomatoes with onion and garlic makes for a rich and savory soup base.

SEASONING – Italian seasoning gives this soup its signature Italian style flavor. Garnish with shredded Parmesan or Romano cheese!

How To Make Hamburger Soup

1-2 and done is all it takes to make this healthy soup! Serve hot with a dollop of sour cream, salsa, or the cheese of your choice and it still stays keto!

  1. Brown ground beef with onion and garlic until no pink remains. Bloom the spices by adding them to this mixture. Drain off any fat.
  2. Add remaining ingredients to the pot and bring soup to a boil. Simmer until the vegetables are tender, about 15 minutes.

Recipe Tips & Tricks

  • If you’re short on time, toss in a bag of frozen “vegetable medley” into the soup pot. They are already cut and ready to use and most medleys have low carb versions, including green beans, cauliflower, carrots, and peas.
  • If cauliflower rice can’t be found, simply cut a whole cauliflower into quarters and run each piece through a food processor over a box grater until small rice-sized pieces are created. Easy peasy!

    I made this today and enjoyed it so much, I thought I made it for myself but my hubby tried it and loved it. He is not a big soup eater. If you enjoy soup you will really like it!

    1. You can find cauliflower rice in the freezer section. If you use regular rice, the recipe isn’t Keto. If you aren’t eating Keto, then go for it!

  2. It is cooking as I’m typing! I know we are going to love it so I made a dbl batch. Can’t wait to eat

      Amazing . So easy and hearty. My entire family loved it. I added a healthy pinch of chili flakes and 2 Bay leaves. Will definitely make it again.

    1. Darn, sorry to hear that Garland. You can always try swapping all the ingredients for a low sodium version! Hopefully, that helps.

    1. Hi Pat, we haven’t tried this recipe in an instant pot so I am not sure of the instructions but I would love to hear how it turns out for you!

    I really love this soup – it’s so hard to find low carb soups that taste good. I did add a cup of shredded cheddar cheese to the pot right before taking it off the stove just until melted. YUM!

    Made this yesterday. Also made keto johnnie cakes, as my family loves cornbread with soup. Small salad, plus keto blueberry dump cake. Excellent meal on a cold damp rainy winter night. Highly recommend. Will be a staple at our home. Thanks for creating and sharing.

    Making this right now! Added a few more cups of broth and a second can of tomatoes to stretch it to a couple more meals. Thank you for the recipe!

    great recipe don’t be afraid to get creative … We used to make left over soup every Sunday All the left overs from the week went into a pot and if always worked out!!

    This was a great starter recipe! I added sautéed mushrooms, Zucchini, kale at the end and worcestershire sauce for a little umami. Would’ve never thought to use this much cauliflower or cauliflower rice…brilliant and delicious! Thanks for sharing.

    1. I haven’t tried it so I can’t say for sure Teresa, but I am sure it would work just fine. I would suggest browning the beef and adding it to the slow cooker along with the remaining ingredients. Then cook on low for 4-6 hours or until the vegetables are tender! If you try it I would love to hear how it turns out!

    1. I haven’t tried it so I can’t say for sure Sue, but I would make sure the radishes cook for 15-20 minutes. If you try it I would love to hear how it turns out!

    This soup was excellent! Cauliflower is a bit hard on my stomach so I just added the 3 cups of florets. I did not miss the potatoes I normally would have added. My hubs also loved the soup as well! Definitely a keeper recipe! Thank you!

    My family and I loved this! We made it again the next night. Couldn’t believe my kids ate all the veggies. I did add some pasta for them the second night. Thank you!
