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.

Pasta night once a week is a must; if we aren’t making this easy spaghetti sauce, we make Pink Sauce Chicken Pasta, or Olive Garden Chicken Pasta.

Why You’ll Want to Make This

  • 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 with little prep.
  • This is my mom’s recipe that I’ve adapted for the slow cooker. I think you’ll love it!
  • No standing at the stove stirring the pot, the crockpot does all the work.
  • Makes plenty for dinner, and leftovers for later in the week, or you can freeze.

Recipe Ingredients

Simple to toss in the crockpot, but this sauce comes together by simmering all day!

Tips & Variations

  • Meat Swaps: You can substitute one pound of Italian Sausage for the ground beef in this recipe. You can also use ground turkey or ground chicken or 2 lbs of frozen meatballs.
  • Adding Wine: 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).
  • Veggies: Add additional vegetables such as diced carrots, celery, or mushrooms.

How to Serve Slow Cooker Spaghetti Sauce

Here is how I serve this spaghetti sauce from the slow cooker to my family and guests:

  • Spoon this homemade spaghetti sauce over your favorite noodles—such as standard spaghetti, angel hair, or bucatini. Try zucchini noodles if you’re keeping it low-carb.
  • You can also use this sauce for slow cooker 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.
  • Reader Suggestion: Stir in some butter just before serving.

Can Raw Ground Beef Be Put in Spaghetti Sauce in the Crockpot?

No, not if you want it to turn out good. Raw meat cooked in the slow cooker, with sauces, turns into sandy bits and just makes the sauce bland and greasy. Cook that hamburger meat on the stove top.

How to Store Extra Spaghetti Sauce:

Place extras in the fridge for up to four days. Or for more extended storage, spoon into small portions and freeze for up to three months. Great for last-minute budget meals.

Sarah’s Notes

DO NOT add uncooked noodles to the slow cooker. The slow cooker doesn’t get hot enough, fast enough to properly cook noodles. The noodles will turn out mushy.

    I seen your recipe for this sauce and cooking it at t his very minute in my so cooker, I have made and tossed many other spaghetti sauce recipes in the trash, I’m hoping yours is going to be a keeper! I used mild ground Italian sausage 1 lb. My wife Susan who battled brain cancer died and her awsome recipes went with her, everyone is eating good in Heaven!

    1. Sarah Olson says:

      I hope you like this recipe Charles. I’m so sorry about your wife, you were lucky to enjoy her recipe while you did.

        It’s a keeper, I added a half of chopped bell pepper. Added more Basil and oregano one quarter cup Merlot wine. Definitely Will make it again, so good and so easy. Thx for sharing this recipe!

      2. Chuck Peters says:

        Almost forgot I also added 18 home made meatballs.

    I will be adding frozen meatballs instead of ground beef. When do I add them? Thanks

    1. Sarah Olson says:

      I would add them the last 2 hours.

      1. Anonymous says:

        Is this two hours low or high?

      2. Sarah Olson says:

        Either would work fine. You can not overcook frozen meatballs, they only get better in the slow cooker (any temp).
