Giant Slow Cooker Meatballs

I don’t know what it is with me and meatballs lately, but here we are again. #sorrynotsorry This weekend I made these deliciously Giant Slow Cooker Meatballs, which are a fun way to change up a simple spaghetti and meat sauce dinner. The whimsically large meatballs simmer away in marinara, the flavors from each seeping into the other, creating a luxe rich sauce for the spaghetti. And I’m telling you, the smell these meatballs create in your house as they cook is almost reason enough to make them! 

This is a great dish to meal prep for the week ahead! The pasta, sauce, and meatball package up quick and easy, reheat like a dream, and you can add a simple side salad (in a separate container) for each day. Done and done!

Ingredients

  • 1/2 lb. ground beef (85/15) $2.65
  • 1/2 lb. Italian sausage (mild, sweet, or hot) $1.16
  • 1 large egg, slightly beaten $0.26
  • 1/2 cup plain breadcrumbs $0.12
  • 1/4 cup grated Parmesan $0.44
  • 1/4 tsp onion powder $0.02
  • 1/4 tsp garlic powder $0.02
  • 1/4 tsp salt $0.01
  • 1 26 oz. jar marinara sauce $2.19
  • 12 oz. spaghetti $1.13

Instructions

  1. Add the ground beef, Italian sausage, beaten egg, breadcrumbs, Parmesan, onion powder, garlic powder, and salt to a bowl. Use your hands to combine the ingredients until they are evenly mixed. Divide the mixture into four equal portions, then shape each into a ball.

  2. Place the meatballs in the slow cooker and pour the marinara over top, making sure to coat the top of each meatball. The sauce will only come up about half way to the top of the meatballs, but that's okay. The slow cooker will fill with steam, which will help cook the meatballs even though they are not completely submerged.

  3. Place the lid on the slow cooker and then cook on high for 3 hours, or low for 6-7 hours. Use an instant read thermometer to make sure the meatballs have reached at least 160ºF on the inside (mine had exceeded this temperature after 3 hours on high). 

  4. Near the end of the cook time, cook the spaghetti according to the package directions, and then drain in a colander.

  5. Remove the cooked meatballs from the slow cooker, then add the cooked and drained spaghetti, and toss it to coat in the sauce. Divide the sauced spaghetti between four plates, add one giant meatball to each, then enjoy.

Giant Slow Cooker Meatballs Ingredients

In a large bowl combine 1/2 lb. ground beef (85/15), 1/2 lb. Italian sausage, 1/2 cup breadcrumbs, 1/4 cup grated Parmesan (sorry that one is not in the photo), 1 large slightly beaten egg, 1/4 tsp garlic powder, 1/4 tsp onion powder, and 1/4 tsp salt.

Use your hands to mix these ingredients together until they’re evenly combined, then divide the mixture into four equal portions, and shape each into a ball. The meatballs will be slightly smaller than a baseball.

Add Marinara Sauce to Giant Slow Cooker Meatballs

Place the meatballs in the slow cooker and pour one 26oz. jar of marinara sauce over top, making sure to coat the top of the meatballs. The sauce will only come up about half way up the meatballs, but that’s okay. The steam in the slow cooker will help cook the meatballs through even though they’re not completely submerged.

Place the lid on the slow cooker and cook on high for 3 hours or low for 6-7 hours. It’s always a good idea to use an instant read thermometer to make sure the internal temperature of the meatballs has reached 160ºF. (I use this thermometer – As an Amazon Associate I earn from qualifying purchases.) Mine had exceeded this temperature after 3 hours on high.

Remove Giant Meatballs from Slow Cooker

When the meatballs are almost done, cook 12oz. spaghetti according to the package directions, then drain it in a colander. Remove the meatballs from the sauce in the slow cooker.

Add Cooked Spaghetti to the Slow Cooker

Add the cooked and drained spaghetti to the sauce in the slow cooker and toss to coat. All that fat that was on top is quite flavorful and makes the sauce ultra rich and delicious!
