    It’s February, it’s cold and dreary, and you need plenty of hearty keto soup. You also want it to be easy, flavorful, and satisfying.

    Well then, head to the kitchen and make a big batch of this Italian Sausage & Vegetable Soup. The smell of it alone will make your mouth water.

    It’s the kind of recipe you will find yourself making over and over again. I’ve already made it 3 times in the past month!

    Easy keto sausage soup

    This is one of those easy keto dinner recipes that I created on the fly and it just worked. I had various vegetables languishing in the fridge, and some good Italian sausage in the freezer.

    So I sautéed the pork, tossed in the veggies, and added some broth. I stirred in a little tomato paste for color, and some Parmesan rind for added flavor. Then I let it simmer and do its thing.

    The result was so rich and delicious. And with all those vegetables in there, it was a full meal in a bowl. I knew I had to make it again. And again.

    Ingredients

    This easy soup recipe takes basic ingredients available at any grocery store. You will need:

    • Olive oil: Any neutral oil will work, including avocado oil.
    • Spicy Italian sausage: Look for good sausage that doesn’t have a lot of extra carbs or sugars. You can use mild sausage if you prefer. If it comes as links, cut the casings off prior to cooking.
    • Celery
    • Onion: Just ¼ cup adds flavor without adding too many carbs
    • Chopped vegetables: The great part about this soup is that you can use whatever low carb veggies you need to use up. It’s a great recipe to help you clean out your fridge.
    • Bone broth: I used beef broth but you could use also use chicken.
    • Tomato paste: Adding 1 tablespoon of tomato paste gives the soup a rich color.
    • Parmesan rind: This ingredient is optional but it adds wonderful richness.
    • Salt and pepper to taste

    How to make Sausage & Vegetable Soup

    1. Sauté the sausage: Heat the oil in a large soup pot over medium heat, then brown the sausage all over. Break up any clumps with a wooden spoon.
    2. Add the celery, onion, and garlic: There’s no need to transfer the meat out of the pot, the veggies can just be mixed right in. It saves a step and a dish!
    3. Stir in the other vegetables: Once the aromatics are becoming tender, you can add the remaining vegetables. Stir them to coat with the oils in the pot.
    4. Add the broth and tomato paste: Stir well to mix the tomato paste in.
    5. Add the Parmesan rind: Don’t worry if you don’t have any, the soup will still be delicious. It’s just a little trick I picked up for Italian style cooking that adds another element of flavor.
    6. Simmer: Bring the whole pot to a low boil, the reduce the heat and simmer until everything is tender.
    7. Discard the Parmesan rind: Like bay leaves, you want to remove and discard the rind before serving.
    8. Season to taste: Because sausage, Parmesan and broth all contain salt, you want to adjust the seasonings at the very end of cooking.

    What to serve with Italian sausage soup?

    With plenty of meat and vegetables, this soup is really a full meal on its own. However you can round out your meal with some keto bread or crackers.

      Made this tonight and the flavors were outstanding. I was apprehensive because Italian sausage has a strong flavor but the beef bone broth carried the lead and all of the veggies chimed in too. Thank you for a new and delicious soup recipe.

      Sitting here right now, slurping up this incredibly DELICIOUS soup…and telling ALL my friends about it! My taste-buds totally understand why Carolyn made this 3 times in one month…definitely going to be a staple recipe for the upcoming winter months! Didn’t have the Parmesan rind, so added some Locatelli (Pecorino Romano cheese) after serving…just divine! A 10, by my palate!!! Thank you, Carolyn!!! ????????????

      This recipe lists “1 small red pepper”: is that a red bell pepper by chance or a spicy pepper?

      Please clarify!

      TIA . . .

        It’s a standard bell pepper. If it was a hot pepper, I would be very specific and name the variety. So always assume regular unless otherwise specified.

      Thanks for another “veggie” soup. I believe I will can some of the basic meat & broth and add in whatever veggies are around when I open up a jar to consume it.

      getting soup season????.. I made this a lot last yr. I recently discovered tomato powder. works great in dishes like this, no wasted tomato paste cans. I can’t wait to try tomato powder in this recipe. 1 or 2 tablespoons is all I use, it gives great flavor.

        Put leftover tomato paste in a Ziploc bag and freeze it. Next time a recipe calls for tomato paste break off a piece about the right size.

      So so good! I had just over a pound of sausage, so I added a bit more of the veggies…turned out great. (and only had sweet Italian sausage so tossed in a pinch of red pepper flakes). Highly recommend…can drink the broth with a straw!

      My husband and I prepared this soup for dinner last night. It was absolutely delicious. Thanks for another great but simple recipe. I also made your focaccia bread to go with it. So good!
