Crockpot Spaghetti Sauce
Ok so you want to make our Crockpot spaghetti and meatballs but make your own sauce. Totally possible. You’d want to start with this in the morning so it can get a deeper flavor throughout the day. Then add the noodles when you get home.
The next time you go to the store grab a roast. Simmered in the sauce it comes out super tender and creates a really hearty meal. Of course you can omit it entirely and make homemade vegetarian spaghetti sauce but…..
If you too love slow cooker recipes of all kinds, you’re going to go crazy over this one. First let’s go over a few resources:

Slow Cooker Ragu Sauce
As with any other recipe with beef cooked in a Crock, you’ll want to brown the outsides first. Ok, so you could skip this step but it is a good idea to keep it tender and add a bit of texture.
Slow Cooker Spaghetti Sauce with Beef
This time we just made the sauce. Timing for that is 8 hours. If you want to add noodles and make Crockpot spaghetti and meatballs with ground beef is closer to 6 hours. Both are excellent.
If you wanted to add noodles too you could during the last hour with 1 c. broth. You’d need to fully submerge it and small shells are the best, or break spaghetti noodles into thirds.
Can you put raw ground beef in spaghetti sauce?
No. You need to brown it first before adding. No matter how you cook it you’d be safer to cook it until it’s no longer pink beforehand. You could use our Crockpot ground beef recipe, quickly make some air fryer ground beef, or just use a pan on the stovetop.
If you have smaller kids I might opt for penne pasta instead of regular longer versions. It’s easier to eat and leads to less of a mess.

Crockpot Spaghetti Sauce Recipe
If you follow the below recipe exactly and when it’s done you think it is too thick, just add some broth. Easy peasy. This is what you’ll want to take out.
- Beef roast and large skillet to brown
- or brown ground turkey or Italian sausage and use that
- Onion
- Carrots
- Celery
- Diced tomatoes
- Beef broth
- Red wine vinegar
- Tomato paste
- Oregano
- Basil
- Salt and pepper to taste
- Garlic powder
- A bit of sugar
- Bay leaves
Once you sear the meat you just throw it all in. Slow coking makes for the most tender fall apart protein inside.

Slow Cooker Spaghetti Sauce with Meatballs
It saves well too. If you make too much just let it cool to room temperature. Then store in freezer bags, flatten them and stack in the freezer. They will stay well for several months.
My family loves it so much I sometimes make double when I batch cook. When you’re ready to enjoy again just put the frozen bags in the fridge. Let meat sauce defrost on it’s own.
Reheat in a sauce pan, again in the Crock pot just to reheat on low. Thin out with a bit of tomato sauce if needed. Could dice green pepper and add for some texture and serve pasta sauce over egg or spaghetti noodles.

Can you use jar sauce in slow cooker
I mean I guess so but why?? Make from scratch like this, there is an array of variations and add ins for this. Only have crushed tomatoes on hand, use that. Love Italian seasoning well then add some too. A bit of brown sugar adds a bit of sweetness too. It’s a great recipe where you can substitute away.
- Heat a skillet on the stovetop. Add a bit of olive oil with your cut up pieces of roast.
- Sear on all sides and then transfer beef into slow cooker.
- Add diced onions into the same skillet with drippings, add garlic powder
- could add diced garlic too if you’re a lover and cook down until caramelized.
- Add meat and onions into the crockpot.
- Then add all other ingredients with the bay leaves on top so they’re easier to remove at the end.
- Cover and cook for 8 hours or high for 6 hours. Remove bay leaves. Shred beef with two forks.
Serve over air fryer zucchini noodles or regular pasta. Printable recipe shared below so you can keep it on hand. Nutritional information included as well such as saturated fat (which will vary depending on meat selected), calories, etc…
