Slow Cooker Meatballs:

Tomato Sauce:

Spaghetti Squash (Optional):


  1. Prepare the meatballs. In a bowl, combine all ingredients. Using your fingers work the mixture together; work only until all the ingredients are evenly combined.
  2. Roll meat mixture into balls (about golf ball size) and set aside.The mixture should make 18-20 meatballs.
  3. Prepare the sauce. In the slow cooker, add the diced onion and minced garlic at the bottom, cover with tomatoes, tomato paste, add spices, and stir to combine.
  4. Add the meatballs to the slow cooker, laying them out evenly throughout the sauce. Don’t worry if they aren’t submerged completely in the sauce, this will happen naturally as they cook.
  5. Cover the slow cooker and cook on low for 4-6 hours. The meatballs are ready when they are no longer pink. They should be done around 4 hours, but I typically allow them to simmer for up to 5-6 hours.
  6. While the meatballs are cooking, prepare your spaghetti squash. Preheat the oven to 400° F.
  7. Slice the squash in half. You cut it in half either way, but you get longer strands when you cut it horizontally.
  8. Using a large spoon, remove the seeds from each side of the squash. You are looking to remove the seeds and excess pulp, but not the flesh of the squash. (Note: The seeds can be kept for roasting for a snack!)
  9. Place the squash on a roasting tray and transfer to the oven. Cook for 30 to 45 minutes depending on the size of your squash. Check the squash after 30 minutes to gauge cooking.
  10. The squash is done cooking when you can pierce a fork thru the skin and the flesh separates easily into spaghetti-like strands. If the noodles are still a bit crunchy, return squash to the oven for another 10-15 minutes.
  11. When the squash is done cooking, use a fork to scrape out the flesh from the skin into strands. I find allowing the squash to cook for 5-10 minutes helps to more easily remove the strands.
  12. When the meatballs are done cooking, stir the sauce to make sure everything is well combined.
  13. Serve 3-4 meatballs with a dollop of sauce over strands of spaghetti squash.
  14. Enjoy!
