There are not many meals I can think of that capture the essence of a traditional family comfort food dish more than Spaghetti and Meatballs. Simple, delicious and filling…what more can you ask for?!

But what about when you want all the flavor but you want something a little less filling? In comes Spaghetti and Meatball Soup! All the flavors you love, but less of the overly filling noodle and more delicious tomatoey broth.

This is the perfect slow cooker recipe, make it up in the morning and let those meatballs simmer all day to juicy perfection. Use your own choice of sauce and noodles to customize the flavors.

Ingredients You’ll Need

  • ground turkey – I use turkey instead of beef so keep the grease factor to a minimum. If you decide to use ground beef for your meatballs, be sure it’s super lean
  • rolled oats – as a binder and filler for the meatballs. I used gluten-free for a gluten-free meal
  • parmesan cheese and Italian seasoning to flavor the meatballs plus egg to bind them
  • pasta sauce – use a high quality sauce with a flavor you love. I prefer a tomato basil with no sugar added.
  • chicken broth – to make the soup
  • more seasoning to season the broth
  • spaghetti noodles – any regular spaghetti noodles you like. If gluten-free I find the only option that hold up well to the slow cooker are the Banza Spaghetti Noodles.

How to make spaghetti and meatballs soup in the slow cooker…

First you’ll mix up the meatball ingredients and form them into equal round meatballs. You can go with larger meatballs and make about 10 of them or go with small bite sized ones instead.

Place the meatballs carefully in the bottom of the slow cooker

Add the sauce, broth and extra seasoning but DO NOT STIR! You don’t want to break apart the meatballs, so just leave it alone at this point until it’s done cooking.

Once the meatballs are done, you can stir carefully and they will hold their shape.

Once they are done cooking, turn the slow cooker on high, break up your noodles and add them. The brand and thickness of your noodles will determine cooking time, but most take around 30 minutes, give or take.

Make Ahead Tips

This is another recipe that is great as a make ahead meal. You can make the meatballs in advance and then freeze them.

Then when you are ready to make the soup it is a matter of just adding a few ingredients to the slow cooker and away you go! Perfect for busy mornings!

Be sure to thaw the meatballs before cooking.

  1. Hi, one more question! If I have precooked, frozen meatballs, when should I put them in? I don’t want to overcook them! TIA!

  2. Wow, thank you for the fast response! They are ping pong sized so I’ll make sure I have a dozen. Can’t wait to make this!

  3. Hi, how many meatballs does this recipe make/use? I have some already made and want to know how many to throw in. Thanks!

    1. Totally depends on what size the meatballs are. This recipe uses one pound of meat and so I’d say if you had more bite sized (ping pong/golf ball?) maybe around a dozen?

  4. This looks delicious! Also, thanks for including the crock pot size you used (I have 2 so knowing which one to pull out helps!)

    1. Thank you! I’ve been trying to get better about noting my slow cooker size and cook time. If you see one that doesn’t have just comment or e-mail me and I will most likely be able to remember!!
