  • avocado or olive oil
  • onion
  • celery
  • garlic
  • ground beef
  • sea salt
  • ground black pepper
  • dried basil
  • oregano
  • dried parsley
  • dried thyme
  • cauliflower
  • red pepper
  • green pepper
  • monk fruit / erythritol sweetener
  • organic tomato paste
  • organic diced tomatoes
  • beef broth or bone stock
  • green beans

Monk Fruit / Erythritol Sweetener – We use sweetener in this soup to cut down on the acidity from the tomatoes. You can use any sweetener you prefer, although I like SoNourished or Lakanto‘s monk fruit / erythritol sweeteners the best.

How to make hamburger soup

Wash your veggies, then heat a soup pot on medium heat with a touch of oil.

Cutting board with celery, red and green pepper, green beans, garlic and onion.

Chop up the onion, red pepper, green pepper and celery, and add each to the pot once the oil is hot. Cook until the onion is translucent, stirring the veggies frequently.

Chopped celery, peppers and onion.

Mince the garlic with a knife or garlic press and add it to the pot with the ground beef, salt, pepper, basil, thyme, oregano and parsley. Stir well and then cook until the ground beef is no longer pink.

Soup pot filled with ground beef, cooked veggies, garlic, salt, pepper and other herbs.

In the meantime, chop cauliflower into small pieces, trim the ends off of the green beans and chop them into 1″ pieces. Once the beef is no longer pink, stir in the cauliflower, sweetener, tomato paste, diced tomatoes and green beans. Pour in the beef broth or bone stock until the ingredients are completely submerged in stock, about 8 cups.

Cooked veggies and ground beef with chopped cauliflower, green beans and tomatoes on top.

Bring to a boil, reduce to a simmer and cook for 30 minutes, until the cauliflower is soft. Serve hot and enjoy!

Expert Tips

  1. Chop / dice the veggies up small enough so that you can have more than one veggie at a time on your spoon!
  2. Want to add even more nutrition to this already nutritious bowl of goodness? Use bone stock! Never made it before? Check out this How to Make Bone Stock recipe.
  3. This Keto Hamburger Soup freezes great! Cool the soup to at least room temperature, then pack it into single sized portions using freezer safe ziploc bags or containers. Store in the freezer! It will last 4-6 months in the freezer.

Make this Low Carb Hamburger Soup in a slow cooker

Want to do make this soup in a slow cooker? Here’s how:

Heat a skillet on medium heat with the oil and dice up the onion, red pepper, green pepper and celery. Add the diced veggies to the skillet once hot and cook until the onion is translucent.

Mince or press the garlic and mix into the skillet with the ground beef, salt, pepper, basil, thyme, oregano and parsley. Cook until the beef is no longer pink, then transfer the contents to your slow cooker.

Chop the cauliflower into small pieces, trim the ends from the green beans and chop into 1″ pieces, then add to the slow cooker along with the sweetener, tomato paste and diced tomatoes. Stir well, then pour in enough beef broth to cover the ingredients.

    I made this tonight. I tweaked it a bit. Made a double batch, added canned peas instead of frozen ( don’t like the taste or texture of frozen peas ) and added red bell pepper. It is amazing!

    1. Aleta says:

      I’m so glad you liked it! 😀

  2. Monica Collins says:

    Do you not drain the grease off of the hamburger meat before adding the rest of the ingredients? (Low Carb Hamburger Soup recipe)

    1. Aleta says:

      Hey Monica! It totally depends on how much grease is produced from the beef.. if there is lots of grease, go ahead and dump the grease before adding the rest of the ingredients 🙂

    I have been making homemade soup weekly. With all the snow that is in the forecast, this is just the kind of dinner we need. Always a welcome way to warm up from the cold.

    1. Aleta says:

      It doesn’t usually snow much where I live, but it has been snowing all week and looks to continue for a while… I’m also making soup once a week to fight the chill!

    It is so hard to loose that baby weight so I really sympathise. I’m still trying 4 years after my last baby was born! This low carb hamburger soup sounds like a great meal choice though.

    1. Aleta says:

      It’s very hard, those pounds are so stubborn, at least we’ve got sweet baby love to show for it 🙂

    Don’t worry about carrying around the baby weight — I’ve been doing it for 43 years. But I haven’t given up. That should count for something shouldn’t it? We love soups and have a pot made at least once a week. The hamburger soup looks great — it would be very satisfying during these long cold days. I’m pinning.

    1. Aleta says:

      Hahaha I don’t believe it’ll ever fully go away, but the trying feels good! Thanks Marisa 🙂

    I’m with the other ladies here, still trying to lose that baby weight after almost 13 years >.< So be easy on yourself, there is plenty of time x I love the idea of this soup, it sounds so tasty, in fact, I can almost taste it right now!

    1. Aleta says:

      Thanks Michelle! 🙂

    This looks so yummy! Definitely comfort food — but way more unique than the typical chicken noodle soup! I know what I’ll be cooking up next time I’m feeling sick! 🙂

    1. Aleta says:

      Thanks Amy! I hope you love it and find it comforting

  10. Charity says:

    This looks so hearty and comforting! Perfect for the dead of winter when you want a piping hot dinner.

    1. Aleta says:

      Thanks Charity 🙂

  11. Daniela says:

    Whoa what a combo! Had never heard of hamburger soup… nice idea! Thanks so much for sharing :).

    1. Aleta says:

      Thanks Daniela! You’ve gotta try hamburger soup, it’s delish!

  12. Loreto Nardelli says:

    A plate of this soup would be good about now. We are still in the deep freeze in the northweSt. Cold cold temp and lots of snow. I just want to curl up to a heaping bowl of you hamburger soup. Way better than fast food! Yum!

    1. Aleta says:

      Totally! Thanks Loreto 🙂

  13. Julie says:

    Winter comfort foods are often so heavy and carb loaded; what a great way to still enjoy a warm, hearty dinner during all this cold weather, without all the carbs!

    1. Aleta says:

      Thanks Julie 🙂

    Soup looks so hearty and comforting. I’d help myself with BIG bowl of this soup and some crusty bread on the side. haha! Perfect way to spend cold days.

  15. Donna says:

    i have a question before making the soup… do you really add 1/2 cup tomato paste. That sounded like a lot but I’ll do it if you say to. 🙂 Thanks for answering.

    1. Aleta says:

      Hey Donna! Yes, I really do use 1/2 cup tomato paste. You can absolutely use less if you like, but I like mine to be very tomato-y 😛

      1. Michelle says:

        Hi, this soup looks awesome! I can’t wait to try it! Just wondering, what are your thoughts on substituting tomato paste with rotel? Thanks!

        1. Aleta says:

          Hey Michelle, you can absolutely give that a try!

  16. LGJ says:

    Question…why do you add a sweetener??? I have made soup forever (even hamburger soup) and never had need to sweeten it. Does cauliflower make it bitter????

    1. Aleta says:

      Generally the only soups I add sweetener to are those with a tomato base. Tomatoes can be very acidic, so the sweetener is used to cut it down. If you like tomato based soups without any added sweetener, then you can go ahead and skip it 🙂

  17. Amy says:

    I make this a lot! I add cubed radishes which taste similar to potatoes after they soak up all the beef broth. Yummm

    1. Aleta says:

      So glad you like it Amy! I love your idea of the radishes – will have to try that next batch!

    Made the base recipe and substituted Quorn crumbles for ground beef. Only other tweaks were to leave out the green beans, add 1 tsp of marjoram, 1 tbs of soy sauce, and ignored the quantity of cauliflower and put in an entire medium head. Oh- also sautés the onion and peppers in the instant pot and set to soup. This is our new family favorite soup. The spice, flavors and savory were spot on. Even better the next day.

    1. Aleta says:

      Sounds great, Rob! So glad you liked it 🙂

    2. Julie Mills says:

      I looks delicious I’ll have to make it this upcoming winter. I’m not a soup person in the summer.

  19. Janet says:

    Thank you for this awesome recipe. My niece and her husband are not feeling well and I asked them what I could do. They said that they would love a keto friendly meal. I found this recipe. It is nourishing and comforting. It is perfect!

    1. Aleta says:

      What a lovely aunt! I hope they feel better and enjoy the soup 🙂

    I did make a couple of modifications. I have made the soup twice and both times I used 1/4 head of cabbage in lieu of the celery. I also did not add any salt because my wife has a salt restriction. I used a product called Organic No Salt from Costco. The soup is delicious. Excellent recipe!!!

    It got thumbs up from my wife and two adult daughters and my 9 year old grandson. My 11 year old son and 5 year old grandson would not even give it a chance. Bravo!!!

    1. Aleta says:

      Hey Jeff, I love your idea of swapping out the cabbage in place of celery. Glad you all loved it so much!

    Delicious, added green beans.

    1. Aleta says:

      Awesome, glad you enjoyed it Stacey 🙂

  23. Kattie Nelson says:

    Loved this recipe. I added more salt.. onion powder, garlic powder, cayenne and paprika(our household like a bit of a kick)…then topped with parm cheese. So so so good! Thank you for sharing!

    1. Aleta says:

      So glad you loved it Kattie!

  24. Susan says:

    Made this for a low carb dinner and it was delicious. Very well balanced hearty soup. I didn’t have a head of cauliflower so I substituted with a bag of picsweet herb flavored cauliflower rice. I will definitely make this again.

    1. Aleta says:

      I’m so glad you liked it Susan! And love your substitution idea 🙂

    I absolutely loved this soap and my husband and I both agreed that it’s better the next day!!

    1. Aleta says:

      Thanks great Pam! So glad you both love it so much 🙂

  26. Vicki says:

    Can I substitute Broccoli instead of cauliflower? We don’t like cauliflower?
    The rest sounds good! Want to try this soup!

    1. Aleta says:

      Oh sure! Just add the broccoli for the last couple of minutes so that it doesn’t overcook 🙂 Enjoy!
