How To Make Costco Meatballs Crockpot Recipe
- Mix and Shape Meatballs: In a large bowl, combine the ground beef, Italian bread crumbs, chopped onion, minced garlic, fresh parsley, and beaten egg. Use your hands to mix well until evenly combined, but be careful not to overwork the meat. Shape the mixture into 16 uniform meatballs.
- Combine Sauce and Add Meatballs: Pour the spaghetti sauce, crushed tomatoes, and tomato puree into the insert of a slow cooker and stir to combine. Gently place the raw meatballs into the sauce mixture.
- Slow Cook: Cover the slow cooker and cook on the Low setting for 6 to 8 hours.
- Serve: Once the meatballs are cooked through and tender, serve them hot with the sauce.

Recipe Tips
- How to get the most tender meatballs? The key is not to over-mix the meat mixture. Combine the ingredients with a light hand just until everything is blended. Overworking the ground meat can result in tough, dense meatballs.
- How can I add more flavor? For a deeper, richer flavor, you can take an extra step to brown the meatballs in a hot, oiled skillet before adding them to the slow cooker. This is not required for this easy recipe, but it adds a lot of complexity.
- How do I make sure the meatballs are all the same size? Using a medium cookie scoop (about 2 tablespoons) is the best way to ensure all your meatballs are uniform in size. This helps them cook evenly in the same amount of time.
- Can I use a different kind of meat? Absolutely. You can make these meatballs with a combination of ground beef and ground pork, or substitute ground turkey for a leaner option.
