Italian Meatball Soup

The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions and to ensure that you have all the ingredients and equipment required as well as understand the steps and timings involved.

As summer turns to autumn, I always seem to cook more soup. There is nothing like a comforting bowl of soup for lunch or dinner when the weather starts to turn a little bit more chilly.

However, with the crazy heatwave we’ve been having, it’s quite good that this Italian meatball soup is good to eat all the year round!

Plus it’s Slimming World friendly so it won’t knock you off plan.

This soup is full of flavor and is really filling too thanks to cannellini beans (which actually get puréed and become the soup along with stock), pasta, and of course the meatballs.

It’s the kind of soup the whole family will love – even if they aren’t on SW. That’s one of the great things that I love about this particular plan. I can cook meals and know that my family will enjoy them and I get to stay on track.

The soup takes just under an hour to prepare and cook, so allow yourself the time to do that if making on a week night. That said, I’ve got some meal prep ideas down in the tips section!

This recipe for Italian Meatball Soup serves 4 and is ½ Syn per serving when Food Optimising.

Recipe Tips

  • First and foremost this is a Slimming World recipe, so make sure you use beef mince (ground beef) that is 5% fat or lower to make your meatballs.
  • The meatballs are cooked before adding to the soup towards the end of cooking to heat them through.
  • This means you can make the meatballs in advance when you have more time!
  • Make and cook the meatballs, allow to cool for 30 minutes before covering and transferring to the fridge. Remove them about 30 minutes before you make the soup so that they can come to room temperature.
  • The cooked meatballs can be stored in the fridge for up to 3 days, or up to 3 months in the freezer.
  • When freezing the meatballs, cool completely (no more than 2 hours) before laying on a baking sheet and placing it in the freezer. When the meatballs have frozen, transfer them to a freezer-safe Ziploc bag.
  • Defrost the meatballs in the fridge overnight before using them in a recipe.
  • Why not make a big batch of meatballs when you have more time and store them in the freezer.
  • Stock pots, liquid stock, bouillon powder, and stock cubes are all FREE on Slimming World (check your Food Optimising book or online for most up to date info) so use whichever kind of stock is suitable. I make mine with chicken OXO cubes.
  • The cannellini beans are whizzed together (in a blender, food processor, or using an immersion blender) with some of the stock and acts as a thickening agent for the soup.
  • If you find the soup is a bit too thick because the pasta has absorbed too much liquid, add extra stock to thin it out to desired consistency.
