  • 4 lb Spaghetti Squash Washed & Scored
  • 2 lbs Lean Ground Beef
  • 24 oz jar Marinara Sauce Divided
  • 2 Tablespoons Dried Minced Onion
  • 2 teaspoons Minced Garlic I used freeze dried
  • 2 teaspoon Pizza Seasoning or Italian Seasoning
  • 2/3 Cup Shredded Parmesan
  • 2 Egg
  • Garnish Shredded Mozzarella or Parmesan
  • salt to taste.


  • After scoring the Spaghetti Squash, wrap it in foil and place in a 6 quart or larger slow cooker.
  • Mix together 1/2 cup of the Marinara with the beef, onion, garlic, seasoning, Parmesan cheese and eggs and form into 24 meatballs.
  • Carefully place meatballs around the squash, stacking as necessary but do not press them together.
  • Cook on high for 4-6 hours until meatballs are cooked to 165 degrees and you can easily insert a knife into the squash.
  • Carefully remove squash and set aside.  Squash will be hot. Slice quash in half and scoop out seeds to discard. Allow to cook briefly before handling further.
  • Meanwhile, carefully break apart meatballs in the slow cooker and stir in remaining marinara sauce.
  • Then use a spoon or fork to scrape squash until squash "noodles" begin to break off and place squash noodles in the crock pot, salting to taste and stir.
  • To serve, plate squash and meatballs and top with cheese.



  • We used our Low Carb Meatball Mix (doubled, 24 meatballs) for this dish. If you don't want quite as many meatballs, we have made this dish with 12 meatballs before and enjoyed it as well.
  • If you aren't eating Low Carb, you could also use the mix from our Freezer Meatballs instead.
  • When purchasing your spaghetti squash pay attention to shape. Try to find one that will easily fit inside your slow cooker.
  • Wash and score your spaghetti squash like you would a baked potato- pricking skin with a knife several times on all sides.
  • If you didn't pay attention to bullet point #3 ;) ... And the lid of your slow cooker does not lay like usual, you can always use foil around the lid and top of slow cooker to keep the heat in.
  • When using our recipes for homemade meatballs, no liquid needs added to the crock pot using this method. We haven't tested this method with pre-made frozen meatballs.
  • The marinara sauce you choose will greatly impact your carb counts. We typically use Rao's sauce but use it sparingly because of the cost. We recently were told about the brand Mezzetta that has a low carb count that we find is much cheaper in our grocery store.
  • Check out all our favorite recommendations for cookbooks, slow cookers and low carb essentials in our Amazon Influencer Shop.
  • You can find more low carb recipes in our Low Carb Recipe Library that we update weekly.
  • Looking for more recipes? Our Recipe Finder can help you find exactly what you need.
  • As with any of our recipes, carb counts, calorie counts and nutritional information varies greatly. As a result, your nutritional content depends on which products you choose to use when cooking this dish. The auto-calculation is just an automated estimate and should NOT be used for specific dietary needs.
  • All slow cookers cook differently, so cooking times are always a basic guideline. Recipes should always be tested first in your own slow cooker and time adjusted as needed.
