Ingredients Needed

Here is the list of ingredients that you will need to make this recipe, with my tips and suggestions. 

  • Frozen Meatballs – You can use either homestyle meatballs, Italian style meatballs, or Turkey meatballs. I prefer to use the frozen meatballs from Costco. If you are using meatballs from a large bag (like the Costco one) then count out 60 meatballs. 
  • Spaghetti Sauce – This is where you can switch up this recipe. You can use any spaghetti sauce you want! I prefer to use a basic one like tomato & basil but there are lots of options at the store. 
  • Italian Stewed Tomatoes – Stewed tomatoes have so much flavor to them which is what gives the sauce lots of Italian flavor. They are chunky which is why you want to throw them in the blender before adding them. 
  • Tomato Paste – This helps thicken the sauce.
  • Italian Seasoning
  • Dried Basil
  • Garlic Powder
  • Salt + Pepper
  • Sugar – Don’t skip this! You need setting to balance all the acid from the tomato based products. 
  • Spaghetti Noodles + Parmesan Cheese – This is for serving. My family loves thin spaghetti noodles with these meatballs.

Tips For Success

Here are my tips for this recipe that will hopefully make it a family favorite in your own home. 

  • Meatballs : Use meatballs that you love! I think the Kirkland Signature brand of frozen meatballs (from Costco) are the absolute best. The bag comes with enough to make this meal at least twice and they’re cheaper than the ones in the store. If you are using meatballs from a larger pack then you will need to count out 60 meatball. Otherwise, a 32 oz bag of frozen meatballs from the store will work just fine too. 
  • Pasta Sauce : Use any flavor you want! Just make sure it’s a 24 ounce jar which is called for in the recipe. 
  • Blend Stewed Tomatoes : The stewed tomatoes have so much more flavor to them but they are in large chunks. My kids would never eat it which is why I blend it up in t blender beforehand. If you want the chunks then feel free to skip the blending part and just add the cans right in. 
  • Warm Setting : This does really well on the warm setting on your slow cooker. So no need to worry if you’re not home right away, just set it to the warm setting when it’s done, and it will stay good for several hours like that. 

Variation & Substitution Ideas

Here are some ways that you can switch this recipe up if wanted. 

  • Pasta Sauce : Use any variety or flavor you want. You could probably even try this recipe with a jar of Alfredo sauce for a different flavor. The mini meatball pasta sauce is a great option for even more meatballs. I usually stick with a basic tomato & basil flavor. 
  • Tomato Paste : For some added flavor use Italian tomato paste (tomato paste with Italian herbs). I have done this lots of times and it’s really good. 
  • Meatballs : Use any style of meatballs you like. Turkey, beef, Italian style, homestyle, and even plant-based meatballs. 
  • Pasta : Use any shape of pasta for serving!

Slow Cooker Spaghetti and Meatballs is so easy to make thanks to frozen meatballs, canned tomatoes, pasta sauce, and seasonings. This cooks in the slow cooker all day and it does really well on the warm setting too. Serve over noodles with parmesan cheese.


  • 1 bag (32 oz) frozen meatballs (about 60 meatballs)
  • 1 jar (24 oz) spaghetti sauce
  • 3 cans (14.5 oz each) Italian Recipe Stewed Tomatoes
  • 1/4 cup tomato paste
  • 1 teaspoon dried basil
  • 1 teaspoon garlic powder
  • 1 teaspoon Italian seasoning
  • 1 teaspoon granulated sugar
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • cooked pasta & parmesan cheese for serving


  • Spray the insert of the slow cooker with cooking spray.
  • Put the frozen meatballs into the slow cooker. Dump the can of spaghetti sauce over the meatballs.
  • In a blender, combine the undrained cans of stewed tomatoes, tomato paste, dried basil, garlic powder, Italian seasoning, salt, and pepper. Blend until combined well. Pour into the slow cooker. Stir everything together until the meatballs are coated in sauce.
  • Cook on LOW heat for 6-7 hours. It does really well on the WARM setting once the cook time is done, if needed.
  • Serve over hot cooked pasta and garnish with parmesan cheese.


Tomato Paste : The small 6 oz can of tomato paste is plenty for the 1/4 cup. There will be a tad bit extra in the can. 
Nutrition Information : Calorie count is for 6 meatballs + serving of the sauce. It does not include pasta. To reduce calories use spiraled zucchini pasta or serve over garlic cauliflower rice ( I find this in the frozen vegetable section and it cooks real quick in the microwave).

    Sounds great, but in my situation of getting up at 4 am and usually cooking on slow for 10 hours, how many hours does this recipe take to get done.

    Thanks in advance for your response

    1. Together As Family says:

      If your slow cooker automatically goes to the ‘warm’ function after the cook time (most do) then this would be fine staying on the warm setting until you get home. It only needs 6-7 hours to cook but will do just fine on the warm setting. That’s what I would do. Hope that helps.
