Crockpot spaghetti and meatballs with jar sauce is a game changer! NO need to boil noodles when making this pasta dinner in your slow cooker. Homemade comfort food starting with frozen meatballs in Crockpot, meatless, or create homemade if you’d rather.

Have you ever tried making Crockpot spaghetti and meatballs with jar sauce yet? Tender and super flavorful with just a few ingredients = the perfect easy Crockpot recipe your family will love. Use frozen meatballs or homemade, we will explain both below. (affiliate links present)
Slow Cooker Spaghetti
Yes you can make this much faster if you want to follow our Ninja foodi spaghetti recipe. Love the old fashioned method better? This is the best way to make it so dinner will be ready in the evening.
It may seem too obvious, but maybe you didn’t know you could put uncooked beef and noodles in your slow cooker and have it come out perfect! You can throw in some homemade precooked ground beef balls or make a few frozen meatballs in air fryer with the noodles separate and then combine at the end if you prefer.
with Frozen Meatballs
You can do this to make our Instant Pot spaghetti recipe too. A pressure cooker will make this much faster, like in 10 minutes, no kidding. BUT if you prefer low and slow ways of cooking then we have easy directions below. Just throw those in, no defrosting beforehand necessary which is nice.
with Jar Sauce
You can start with jarred sauce or make your own homemade slow cooker spaghetti sauce first and then just submerge the noodles. It depends on how much time I have whether I do one or the other.
Can you cook noodles in a crockpot?
Yes, you don’t even need to precook or boil them. Just throw them right in, submerge in your liquid, close the lid and walk away y’all!

Yep, you need what you’d normally bring out for this old fashioned Italian meal. BUT you don’t need a pot full of water this time!
Ingredient Notes
- Spaghetti noodles of course, but any shape will work
- Large jar of spaghetti sauce, or make your own with crushed tomatoes and seasonings etc…..
- Beef broth gives this a lot more flavor than just using water for liquid
- Ground beef for meatballs, these are optional, could use premade frozen meatballs, make these basic meatballs or add porcupine meatballs Instant Pot style at the end.
- Mozzarella and parmesan cheese – also optional but why wouldn’t you add cheese to everything??!!
Yes you could half this if you have a smaller family or crowd. This uses an entire package of noodles so if you typically cook 1/2 then just cut this entire slow cooker spaghetti recipe in half.


Crockpot Spaghetti and Meatballs Recipe
Equipment
- 1 slow cooker
Ingredients
- 2 lbs ground beef, or use frozen meatballs
- 1/4 c Italian bread crumbs
- 1 egg
- 1 tsp garlic salt
- 1 tsp garlic powder
- 1 tsp Italian seasoning
- 2 jars spaghetti sauce, 24 oz. each jar
- 1 c chicken broth, or beef broth
- 24 oz spaghetti noodles, uncooked
- 4 c mozzarella cheese, shredded
- parsley, optional
Instructions
- Pour one jar of spaghetti sauce into your crockpot.
- Combine ingredients for meatballs (ground beef, egg, Italian bread crumbs, garlic salt, garlic powder and Italian seasoning) in a bowl well. Form balls that are about 1.5" in size. (or skip and use frozen meatballs, defrosted first in microwave)
- Place formed meatballs in crockpot on top of sauce in one layer. Sprinkle 2 c of shredded mozzarella cheese on top of those, then pour second jar of spaghetti sauce on top of your cheese.
- Cook on high for 3 hours or low for 6 hours (I prefer low and slow)
- During the final hour of cooking add chicken broth and uncooked spaghetti noodles. Best way to do this is pour broth in, break noodles into thirds and gently submerge them on the top into the liquid.
- Top with remaining cheese, put lid back on and during that last hour the noodles the noodles will become tender.
- Garnish with parsley and serve!

Tips
You don’t always have to use traditional long spaghetti noodles to make this crock pot spaghetti and meatballs recipe either though. If you love small farfalle then use those. Tip: In order for your noodles to cook perfectly tender you’ll want to gently submerge them into the sauce below.
Don’t push it all the way down to the bottom past the meatballs, just under the surface is fine. I also usually break the long spaghetti noodles in half or even into thirds. Sprinkle them in instead of throwing them in in one big clump. If you do the latter they will likely cook but stick together in one big clump.
Adjust time if you want them al dente but cooking time below is for the perfect tenderness really.
You don’t have to precook the meatballs either!! Total time saver right?? We love meals like this crockpot lasagna casserole but these do require that the ground beef is cooked beforehand. Not a huge deal, takes maybe 10 minutes, but if you’re in a rush this crockpot spaghetti recipe is so quick.
Of course you can opt to go meatless and make this a vegetarian spaghetti using vegetable broth instead of chicken or beef. Totally up to you but we are all about the beef included within this baby.

Can I keep spaghetti warm in a crockpot?
If you are serving this for brunch where people will be eating at different times throughout a lengthy period of time you could keep this on warm. Just make as directed below, stir, and select keep warm setting on your crock.
I would suggest that you stir it at least every hour so the noodles stay moist with the sauce in your pot. Of course it is ideal to serve it fresh right after it’s done but this is another option for a potluck occasion too.
Other easy crockpot recipes
Our favorite meal is easy as ever and we call it 5 ingredient crockpot chili. A crockpot pizza is a fun dinner idea as well as our slow cooker pizza casserole. This easy crockpot lasagna recipe requires NO boiling ahead of time either. Total game changer for lasagna lovers. We have this pressure cooker lasagna casserole too if you need dinner done in 30 minutes or less

What adjustments do you recommend if making this in a Ninja Foodi using the slow cook function?
Let me be honest….do NOT ever use the slow cooker function with a Foodi or Instant Pot, it doesn’t work well at all. Instead use this tried and true loved version for your Foodi https://temeculablogs.com/cheesy-ninja-foodi-spaghetti/
Amazing recipe!
Yay, it’s our fave too
For the last hour does it matter if its low or high?
