Slow Cooker Spaghetti Sauce is a hearty blend of beef, tomatoes, and aromatic herbs, slow-simmered to perfection. This flavorful meat sauce pairs beautifully with any type of pasta for a satisfying, homemade meal.
When it comes to pasta sauce, your first thought might be to grab a few jars from the grocery store. While that’s certainly convenient, you can just as easily whip up a delicious, homemade sauce right in your own kitchen. Skip the store-bought jars and try this amazing recipe for a sauce that’s as good as grandma’s.
What You’ll Need
Ground Beef – Cooked and drained for a hearty base.
Canned Tomatoes – Crushed, diced (undrained), and tomato paste for rich texture and flavor.
Onion & Garlic – Diced onion and fresh minced garlic for depth and aroma.
Seasonings – A blend of brown sugar, oregano, basil, salt, pepper, and red pepper flakes for the perfect balance of sweet and savory.
A Large Crockpot
How to Make Slow Cooker Spaghetti Sauce
Making this slow cooker spaghetti sauce is as easy as it gets. Just brown some ground beef on the stove, then toss it into your crockpot with the tomatoes, seasonings, and a few extras for flavor. Let it simmer low and slow until everything melds into a rich, comforting sauce. By dinnertime, all you need to do is boil some pasta and sprinkle on a little parmesan—dinner’s done!
Cook’s Notes
You can substitute one pound of Italian Sausage for the ground beef in this recipe. Cut the salt in half for the recipe in half if you use Italian sausage. You can also use ground turkey or ground chicken.
Use a 2 lb. bag of frozen meatballs if desired in place of the ground beef.
Add a half cup of red wine at the beginning of the recipe if you would like a red wine flavored sauce. I like to use red blend when I’m cooking (and for drinking).
Add additional vegetables such as diced carrots or mushrooms.
How to Serve:
Here is how I serve this spaghetti sauce from the slow cooker to my family and guests:
- Spoon this hearty sauce over your favorite noodles—such as spaghetti, angel hair, or bucatini. Try zucchini noodles if you’re keeping it low-carb.
- You can also use this sauce for lasagna or try it in a ravioli lasagna for a fun and different twist.
- Serve it up with garlic bread, breadsticks, or any crusty bread you love to round out the meal.
- And don’t forget—this sauce freezes really well, so save some for an easy dinner later!
- Reader Suggestion: Stir in some butter just before serving.

This caught my eye as I’m looking for a new spaghetti sauce recipe, my question is this, can I use all crushed tomatoes instead of the diced tomatoes, still using the paste as well? I can’t do tomato chunks. Thank you
Yes, that will work fine!
Add some butter as an option near the end. Marcella Hazan would be proud.
Great recipe thank you.
Are these recipes available on tik tok ?
Hi Anthony! Some are! I need to start making more of them.
Will 4 QT crock pot be big enough for this recipe? Thank you
Yes!
How long will this last in the fridge? I need it for a big party (60 people) on Saturday. If I make it Thursday will it be ok for the party on Saturday?
I would make it fresh myself, ground beef can taste off if leftover that long.
Can you use meatballs and ground beef together in the crock pot
I don’t see why not!
Superb
This recipe sounds amazing! I have frozen tomatoes from my garden that I want to use up. Do you have a suggestion on how I could use them for this recipe?
