Ingredients for Making Keto Italian Meatball Soup
- Ground beef - I recommend 85% lean. Ground pork or ground turkey may also be used.
- Almond Flour - Finely grated works best to help bind the meatballs.
- Parmesan - If you can, skip the shelf-stable parmesan cheese brands and opt for freshly grated.
- Italian seasoning - This blend of dried herbs will add flavor to both the meatballs and the soup broth.
- Salt and pepper - Adjust to your liking.
- Eggs - I use large eggs, but any kind works. These will help bind the meatballs.
- Gelatin - This helps the structure and texture of the meatballs.
- Avocado oil - You can use your favorite keto-friendly oil. Just be conscious of the smoke point. I don't recommend extra-virgin olive oil here.
- Onion, celery, and garlic - These vegetables add flavor to your soup base. A teaspoon of garlic is approximately one cloves garlic. Garlic powder may be substituted if you like.
- Crushed tomatoes - The kind you get from a can works great here. If you prefer, you can use canned diced tomatoes.
- Beef broth - I always recommend homemade whenever possible! This will give you a richer flavor, but you can also buy broth if you don't have time to make it. If you don't have beef broth, chicken broth may be substituted.
- Heavy cream - If you're low carb rather than keto, you could use half and half instead. If you are avoiding dairy, canned coconut milk could be used.
- Xanthan gum - Optional if you want a thicker soup.
- Palmini Noodles or Zucchini Noodles - It is entirely optional, but if you are craving meatballs and pasta, use either of these as a keto-friendly alternative.

Tips To Perfect Creamy Soup
- Heavy whipping cream is the easiest way to get rich, thick, creamy soup. Of course, when you use a lot, the calories can add up quickly.
- To thicken the soup without adding too much cream, I always recommend using xanthan gum. This binding agent works wonders for achieving that perfect, satisfying texture! When you add it to the saucepan, I recommend sprinkling it in while stirring continuously to avoid any clumping.

Dishes like this Italian Meatballs Soup, on the other hand, are great to eat on keto! All of the ingredients are low in carbs so that you can indulge without worry.
As the name suggests, it's a soup that contains meatballs simmered with other ingredients. Some recipes include additions like pasta or rice, but for this Keto Italian Meatball Soup, we use low-carb fresh veggies instead.
For meatballs, all you need is ground meat and something to bind it. From there, you can add all your favorite seasonings.

Tools Needed to Make Meatball Soup

Storage
Soup is one of my favorite dishes for leftovers. The flavors can get even deeper overnight, and it always reheats beautifully.
This Meatball Soup is a great dish to make for dinner one night, then use any extra as meal prep for later in the week.
Leftover soup should be stored in an airtight container in the refrigerator. It will stay fresh for up to four days.
Can I Freeze Meatball Soup
Absolutely! And you'll be so happy you did when you're looking for a quick meal on a chilly evening. If you have a large batch, I recommend freezing in individual servings so you only have to defrost as much as you need.

Could you tell me what you determined the serving size as? I see serves 12; but it doesn't specify if the serving is 1/2 cup, 1 cup...etc. My husband loves soup & can easily have a 12-16 serving depending on the soup & needs to track his carbs. Thanks

I would weight the recipe and divide it by the number of servings.
